Prevalencia de subtipos de cáncer de mama y su asociación con factores reproductivos / Prevalence of breast cancer subtypes and their association with reproductive factors

Introducción: Los factores reproductivos se asocian con cáncer de mama. Actualmente se estudia el comportamiento según subtipos moleculares. Objetivo: Establecer la prevalencia de estos subtipos y su asociación con factores reproductivos en mujeres atendidas en centros del nororiente colombiano. Método: Estudio observacional de corte transversal, en mujeres con cáncer de mama subtipos luminales y HER2 durante 2012-2021. Se indagaron variables sociodemográficas, factores reproductivos y estadio tumoral. Resultados: En total, 347 pacientes cumplieron criterios de elegibilidad, correspondiendo a luminal A el 49,8% (intervalo de confianza del 95% [IC95%]: 44,5-55,1), a luminal B el 29,1% (IC95%: 24,3-33,9) y a HER2 el 15,5% (IC95%: 11,7-19,4). Las mujeres con tumores de mama luminal B tenían más riesgo de tener estadios localmente avanzados (odds ratio [OR]: 1,83; IC95%: 1,11-3,01; p = 0,02). Agrupando los subtipos luminales frente a HER2 se encontró que el 40,72% de las pacientes con subtipos luminales no habían lactado, frente al 69,71% con HER2 (diferencia estadísticamente significativa a favor de luminal A; OR: 1,91; IC95%: 1,02-3,53; p = 0,041). Conclusiones: La prevalencia de tumores luminales es del 84,5%. Existe asociación diferencial entre el antecedente de lactancia materna y la aparición de subtipos luminales, es decir, las mujeres que no lactaron se corresponden con mayor frecuencia con HER2. No se estableció asociación con otros factores estudiados.

Introduction: Stimulus-estrogenic factors are associated with breast cancer. Currently, the behavior according to molecular subtypes is being studied. Objective: To establish the prevalence of these subtypes and their association with reproductive factors in women attended in centers in northeastern Colombia. Method: Observational cross-sectional study in women with breast cancer subtypes luminal and HER2 during 2012 -2021. Sociodemographic variables, stimulus-estrogenic factors and tumor stage were investigated. Results: In total, 347 patients met eligibility criteria, corresponding to luminal A 49.8% (95% confidence interval [95%CI]: 44.5-55.1), luminal B 29.1% (95%CI: 24.3-33.9) and HER2 15.5% (95%CI: 11.7-19.4). Women with luminal B breast tumors were at higher risk of having locally advanced stages (odds ratio [OR]: 1.83; 95%CI: 1.11-3.01; p = 0.02). Grouping the luminal subtypes versus HER2 showed that 40.72% of patients with luminal subtypes had not lactated, compared to 69.71% HER2 (statistically significant difference in favor of luminal A; OR: 1.91; 95%CI: 1.02-3.53; p = 0.041). Conclusions: The prevalence of luminal tumors is 84.5%. There is a differential association between the history of breastfeeding and the appearance of luminal subtypes, i.e., women who did not breastfeed are more likely to have HER2. No association was established with other factors studied.

Saúde mental e abortamento voluntário na audiência pública da ADPF442/STF / Mental health and voluntary abortion in the public hearing of ADPF442/STF / Salud mental y aborto voluntario en la audiencia pública del ADPF442/STF

O estudo teve como objetivo identificar os argumentos da estratégia de persuasão dos discursos apresentados na audiência pública sobre a Arguição de Descumprimento de Preceito Fundamental-ADPF 442, realizada em 2018, cujo propósito era discutir sobre a interrupção voluntária da gravidez até a 12ª semana. Para tal, foi realizada uma pesquisa de abordagem qualitativa, analítico-descritiva e documental. O objeto de análise foi o registro da audiência, apresentado em vídeo, disponibilizado na plataforma digital YouTube, e em ata lavrada pelo STF, ambos de acesso público. A partir de uma análise do discurso, identificou-se os argumentos utilizados na estratégia de persuasão, que foram sistematizados em quatro categorias de argumentos para cada um dos dois grupos identificados: o grupo pró e o grupo contra a descriminalização do aborto. As três primeiras categorias, Saúde mental, Direito e Saúde pública, mesmo com diferenças na forma de apresentar o argumento, se repetem nos dois grupos. Todavia, a quarta categoria, Pressupostos, se diferenciou. No grupo pró descriminalização do aborto, apresentou-se como Pressupostos filosóficos e científicos, e no grupo contra, como Pressupostos morais. Por fim, a defesa da saúde mental das mulheres foi o principal argumento numa forma de humanizar o sofrimento vivido pelas que desejam abortar e não encontram o suporte do Estado para assegurar sua dignidade, cidadania e efetiva igualdade, garantidas constitucionalmente.(AU)

The study aimed to identify the arguments of the persuasion strategy of the speeches presented at the public hearing on the Action Against the Violation of Constitutional Fundamental Rights -ADPF 442, held in 2018, whose purpose was to discuss the voluntary interruption of pregnancy until the 12th week. To this end, a qualitative, analytical-descriptive, and documentary research was carried out. The object of analysis was the video recording of the hearing available on the YouTube platform, and in minutes drawn up by the STF, both of which are public. Based on a discourse analysis, the arguments used in the persuasion strategy were identified, which were systematized into four categories of arguments for each of the two identified groups: the group for and the group against the decriminalization of abortion. The first three categories, Mental Health, Law and Public Health, even with differences in the way of presenting the argument, are repeated in both groups. However, the fourth category, Assumptions, differed. In the group for the decriminalization of abortion, it was presented as Philosophical and Scientific Assumptions, whereas the group against, as Moral Assumptions. Finally, the defense of women's mental health was the main argument in a way of humanizing the suffering experienced by those who wish to have an abortion and do not find the support of the State to guarantee their dignity, citizenship, and effective equality, constitutionally guaranteed.(AU)

El estudio tuvo como objetivo identificar los argumentos de la estrategia de persuasión de los discursos presentados en la audiencia pública sobre el Argumento por Incumplimiento de un Percepto Fundamental -ADPF 442, realizada en 2018, con el objetivo de discutir la interrupción voluntaria del embarazo hasta la 12.ª semana. Para ello, se llevó a cabo una investigación cualitativa, analítico-descriptiva y documental. El objeto de análisis fue la grabación de la audiencia, que está disponible en la plataforma digital YouTube, y actas levantadas por el Supremo Tribunal Federal -STF, ambas de acceso público. A partir de un análisis del discurso se identificaron los argumentos utilizados en la estrategia de persuasión, los cuales se sistematizaron en cuatro categorías de argumentos para cada uno de los dos grupos identificados: el grupo pro y el grupo en contra de la despenalización del aborto. Las tres primeras categorías ("salud mental", "derecho" y "salud pública") aún con diferencias en la forma de presentar el argumento se repiten en ambos grupos. Pero difiere la cuarta categoría "supuestos". En el grupo a favor de la despenalización del aborto se presentó como "supuestos filosóficos y científicos", y en el grupo en contra, como "supuestos morales". Finalmente, la defensa de la salud mental de las mujeres fue el principal argumento en un intento por humanizar el sufrimiento que viven aquellas que desean abortar y no encuentran el apoyo del Estado para garantizar su dignidad, ciudadanía e igualdad efectiva, preconizadas por la Constitución.(AU)

Prevalência, padrões e fatores associados à contracepção no Brasil e meta-análise da descontinuidade contraceptiva no cenário mundial / Prevalence, patterns and factors associated with contraception in Brazil and meta-analysis of contraceptive discontinuation on the global stage

Introdução: O Brasil tem uma elevada prevalência de uso de contraceptivos entre mulheres em idade reprodutiva. No entanto, observa-se que persistem desigualdades, tanto no acesso quanto em relação ao tipo de método usado, o que pode contribuir para as altas taxas de gestações não planejadas e abortos induzidos no país. Outro fator que contribui para esses desfechos é a descontinuidade contraceptiva, porém este indicador não é monitorado no país desde 1996, dificultando dimensionar a magnitude do problema. Objetivos: Estimar fatores individuais e contextuais associados ao uso de contraceptivos de acordo com a paridade das mulheres brasileiras em idade reprodutiva; estimar os fatores associados ao tipo de método contraceptivo usado pelas brasileiras; e estimar a magnitude da descontinuidade contraceptiva na literatura mundial a partir de uma meta-análise. Métodos: Foram utilizados dados da Pesquisa Nacional de Saúde de 2013 e 2019 para responder aos dois primeiros objetivos da tese. Os desfechos principais foram o uso de métodos contraceptivos (MC) e o tipo de método classificado quanto ao tempo de ação: contraceptivos reversíveis de curta duração (SARCs) e contraceptivos reversíveis de longa duração (LARCs), e MC permanentes. Os fatores individuais foram características da história reprodutiva, do acesso aos serviços de saúde e sociodemográficas; e os contextuais: Índice de Desenvolvimento Humano (IDH), Índice Sociodemográfico (SDI), Rendimento Mensal Médio e Cobertura da Atenção Primária (APS). Primeiramente, utilizou-se modelos de regressão logística multinível para estimar os fatores individuais e contextuais associados ao uso de MC, estratificados por paridade. Em seguida, para estimar os fatores associados ao tipo de MC usado pelas mulheres foram utilizados modelos de regressão logística multinomial, cuja categoria de referência foram as usuárias de SARC. Por último, foi conduzida uma revisão sistemática com meta-análise para estimar a magnitude da descontinuidade contraceptiva (abandono e troca) na literatura mundial, que também considerou a classificação dos métodos em SARCs e LARCs. Resultados: A prevalência do uso de MC foi superior a 80% em 2013 e 2019, e menor entre nulíparas. Entre 2013 e 2019, observou-se uma redução da variabilidade da chance de usar MC entre as Unidades Federativas (UFs) para nulíparas. Mesmo assim, nulíparas que residiam em UFs com melhores indicadores socioeconômicos, tais como maior IDH e SDI, tinham mais chance de uso de MC. Por outro lado, a cobertura da APS foi a única variável que permaneceu associada a maior probabilidade de uso de MC em 2019 entre primíparas/multíparas. Quanto ao tipo de MC, mais de 70% das mulheres usavam SARCs. Mulheres com melhores condições socioeconômicas tinham mais chance de usar LARCs e menos chance de usar métodos permanentes quando comparados aos SARCs. Por outro lado, mulheres com maior idade, paridade e que viviam com companheiro tinham maior chance de usar métodos permanentes em relação aos SARCs. Ao realizar a meta-análise dos dados identificou-se que a taxa de descontinuidade de SARCs foi de 56,8%, enquanto para LARCs foi de 17,8%. Para as usuárias de SARCs, a chance de abandono foi quase 7 vezes maior que a de troca. Das mulheres que descontinuaram, a maioria abandonou o uso de MC devido a efeitos colaterais. Conclusão: Existem desigualdades individuais e contextuais em relação ao acesso à contracepção no país, segundo a paridade das mulheres. Além disso, mulheres com melhores condições socioeconômicas têm mais acesso aos MC mais eficazes, como os LARCs. Destaca-se ainda as elevadas taxas de descontinuidade encontradas na meta-análise, principalmente para os SARCs, MC mais usados pelas brasileiras. Nossos achados indicam a necessidade de retomar a discussão da contracepção no país com políticas e programas voltados ao enfrentamento das iniquidades, à qualificação do acesso, à promoção da equidade, tendo em vista grupos mais alijados, bem como retomar o monitoramento da descontinuidade contraceptiva em âmbito nacional, além de incluir aspectos assistenciais que deem conta de manejar melhor esse fenômeno.

Brazil has a high prevalence of contraceptive use among women of reproductive age. However, it is observed that inequalities persist, both in access and in relation to the type of method used, which may contribute to the high rates of unplanned pregnancies and induced abortions in the country. Another factor that contributes to these outcomes is contraceptive discontinuity, but this indicator has not been monitored in the country since 1996, making it difficult to measure the magnitude of the problem. Objectives: To estimate individual and contextual factors associated with the use of contraceptives according to the parity of Brazilian women of reproductive age; to estimate the factors associated with the type of contraceptive method used by Brazilian women; and to estimate the magnitude of contraceptive discontinuity in the world literature based on a meta-analysis. Methods: Data from the National Health Survey of 2013 and 2019 were used to answer the first two objectives of the thesis. The main outcomes were the use of contraceptive methods (CM) and the type of method classified according to the time of action: short-acting reversible contraceptives (SARCs) and long-acting reversible contraceptives (LARCs), and permanent CM. Individual factors were reproductive history, access to health services and sociodemographic characteristics; and the contextual ones: Human Development Index (HDI), Sociodemographic Index (SDI), Average Monthly Income and Primary Care Coverage (PHC). First, multilevel logistic regression models were used to estimate the individual and contextual factors associated with CM use, stratified by parity. Then, to estimate the factors associated with the type of CM used by women, multinomial logistic regression models were used, whose reference category was users of SARCs. Finally, a systematic review was conducted with meta-analysis to estimate the magnitude of contraceptive discontinuity (abandonment and switch) in the world literature, which also considered the classification of methods in SARCs and LARCs. Results: The prevalence of MC use was greater than 80% in 2013 and 2019, being lower among nulliparous women. Between 2013 and 2019, there was a reduction in the variability of the chance of using CM between the Federative Units (FUs) for nulliparous women. Even so, nulliparous women residing in FUs with better socioeconomic indicators, such as higher HDI and SDI, were more likely to use MC. On the other hand, PHC coverage was the only variable that remained associated with a greater chance of CM use in 2019 among primiparous/multiparous women. As for the type of CM, more than 70% of the women used SARCs. Women with better socioeconomic conditions were more likely to use LARCs and less likely to use permanent methods when compared to SARCs. On the other hand, women of greater age, parity and who lived with a partner were more likely to use permanent methods in relation to SARCs. When performing a meta-analysis of the data, it was identified that the discontinuity rate for SARCs was 56.8%, while for LARCs it was 17.8%. For users of SARCs, the chance of dropping out was almost 7 times greater than switching. Of the women who discontinued, most discontinued MC use due to side effects. Conclusion: There are individual and contextual inequalities regarding access to contraception in the country, according to women's parity. In addition, women with better socioeconomic conditions have more access to the most effective CM, such as LARCs. Also noteworthy are the high rates of discontinuity found in the meta-analysis, especially for SARCs, the MC most used by Brazilian women. Our findings indicate the need to resume the discussion of contraception in the country with policies and programs aimed at confronting inequities, qualifying access, promoting equity, with a view to more marginalized groups, as well as resuming the monitoring of contraceptive discontinuity in nationwide, in addition to including assistance aspects that manage this phenomenon better.

Intention of breastfeeding and association with sociodemographic, obstetric characteristics and experience with breastfeeding among pregnant women / Intenção de amamentar e associação com características sociodemográficas, obstétricas e experiência com o aleitamento materno entre mulheres grávidas

Abstract Objectives: to estimate the intention of breastfeeding (IBF) duration and its association with sociodemographic, obstetric characteristics and experience with breastfeeding among pregnant women undergoing prenatal care. Methods: cross-sectional study, with pregnant women undergoing prenatal care in public health services in Colombo, Paraná, Brazil. The duration of IBF was questioned to pregnant women. Negative binomial Poisson regression with robust variance adjustment allowed estimating crude and adjusted prevalence ratios (PR), and 95% confidence intervals (CI95%) of the association between IBF duration and exposure variables. Results: among the participating pregnant women (n = 604), 7.9% reported having IBF for less than six months, 28.0% from six to 11 months, 38.3% from 12 to 23 and 25.9% for 24 months or more. The mean IBF time was 13.5 ± 8.4 and median of 12 months. Pregnant women with moderate food insecurity (PR=1.34; CI95%=1.04-1.73), multiparous women (PR=1.13; CI95%=1.00-1.26), and who reported having been breastfed as babies (PR=1.19; CI95%=1.02-1.40) had a longer IBF time. Conclusions: food security situation, primiparity and exposure to breastfeeding in childhood are determinants of IBF during pregnancy.

Resumo Objetivos: estimar o tempo de intenção de amamentar (IA) e sua associação com características sociodemográficas, obstétricas e experiência com amamentação entre gestantes em acompanhamento pré-natal. Métodos: estudo transversal com gestantes em serviços públicos de saúde em Colombo, Paraná. O tempo de IA foi questionado às gestantes. Regressão de Poisson binomial negativa com ajuste robusto da variância permitiu estimar razões de prevalência (RP) brutas e ajustadas, e intervalos de confiança de 95% (IC95%) da associação entre tempo de IA e variáveis de exposição. Resultados: dentre as gestantes (n = 604), 7,9% afirmaram IA por menos de 6 meses, 28,0% de 6 a 11 meses, 38,3% de 12 a 23 e 25,9% por 24 meses ou mais. O tempo médio de IA foi de 13,5 ± 8,4 e mediana de 12 meses. Gestantes em insegurança alimentar moderada (RP=1,34; IC95%=1,04-1,73), multíparas (RP=1,13; IC95%=1,00-1,26), e que referiram terem sido amamentadas quando bebês (RP=1,19; IC95%=1,02-1,40) apresentaram maior tempo de IA. Conclusões: situação de segurança alimentar, primiparidade e exposição ao aleitamento materno na infância são determinantes da IA na gestação.

Supresión de la visita de tercer trimestre en embarazo de bajo riesgo en la pandemia de SARS-CoV-2 / Third trimester suppression in low-risk pregnancy in the SARS-CoV-2 pandemic

Resumen Objetivo: La pandemia de SARS-CoV-2 ha obligado a una reorganización de las visitas presenciales, y por ese motivo se han minimizado hasta el punto de reconsiderar la realización de la visita del tercer trimestre. Nuestro centro suprimió dicha visita obstétrica y obtuvo datos propios para comparar los resultados perinatales logrados con dicho manejo. Método: Se realizó un estudio de cohortes retrospectivo, en marzo de 2020, con una cohorte con visita presencial única en la semana 40 de gestación (122 gestantes) frente a una cohorte con seguimiento convencional con visita presencial en la semana 36 de gestación (162 gestantes). Se evaluaron la restricción del crecimiento fetal, la edad gestacional al nacimiento, el peso neonatal y las tasas de inducciones, partos eutócicos y cesáreas urgentes en trabajo de parto. Resultados: Se encontraron diferencias leves en la tasa de nuliparidad (p < 0,04), sin hallarlas en el resto de las variables maternas. No hubo diferencias entre las dos cohortes en los resultados neonatales. Conclusiones: No hay diferencias entre los resultados materno-fetales obtenidos en gestantes con seguimiento gestacional con restricción de la visita del tercer trimestre respecto del seguimiento tradicional, excepto en el diagnóstico de las alteraciones de la estática fetal al término de la gestación.

Abstract Objective: The SARS-CoV-2 pandemic has forced a reorganization of face-to-face visits, for this reason they have been minimized to the point of reconsidering the completion of the third trimester visit. Our center eliminated the performance of this obstetric visit and obtained its own data to compare the perinatal results obtained with such management. Method: A retrospective cohort study was carried out in March 2020, with a cohort with a single face-to-face visit at 40th week of gestation (122 pregnant women), versus a cohort with conventional follow-up with face-to-face visit at 36th week of gestation (162 pregnant women). The following were evaluated fetal growth restriction, gestational age at birth, neonatal weight, rate of inductions, of eutocic deliveries, and of urgent cesarean sections in labor. Results: Slight differences were found in the nulliparity rate (p < 0.04), without finding them in the rest of the maternal variables. There were no differences between the two cohorts in neonatal outcomes. Conclusions: There were no differences between the maternal-fetal results obtained in pregnant women with gestational follow-up with restriction of the third trimester visit compared to traditional follow-up, except in the diagnosis of alterations in fetal statics at the end of pregnancy.

Estudiantes universitarias nuligestas en edad fértil y su postura acerca de posibles vías del parto / Nuligest university students of childbearing age and their position about possible ways of delivery

Resumen Introducción: Tanto a nivel sudamericano como mundial, el incremento de la tasa de cesáreas electivas ha sido abrumante. Esto se considera un problema de salud pública, ya que el parto vaginal es la vía más fisiológica para el nacimiento y trae beneficios de salud para la madre y el recién nacido, tanto inmediatos como a futuro. Objetivo: Evaluar la postura de mujeres nuligestas en edad fértil acerca de las vías del parto a través de sus conocimientos, percepciones y preferencias. Método: Estudio de corte transversal. Se aplicó una encuesta a estudiantes universitarias para la recopilación de datos mediante SPSS, y análisis con prueba de diferencias de proporciones y de χ2. Resultados: 210 mujeres encuestadas. Un 80% de ellas desconoce la menor morbilidad infantil asociada a un parto vaginal, más de la mitad estima una ventaja de la cesárea que evite el dolor y un gran porcentaje desconoce los riesgos médicos asociados a la cesárea. Conclusiones: Existe un alto nivel de desconocimiento respecto a beneficios, riesgos y consecuencias de las diferentes vías del parto.

Abstract Introduction: Both in South America and worldwide, the increase in the rate of elective caesarean sections has been overwhelming. This is considered a public health problem, since vaginal delivery is the most physiological route for birth and brings health benefits for the mother and the newborn, immediately and in the future. Objective: To evaluate the position of nulliparous women of childbearing age regarding the delivery pathways through their knowledge, perceptions, and preferences. Method: Cross-sectional study with an analytical component. A survey was applied to university students for data collection through SPSS, and analysis was made with the difference of proportions and χ2 test. Results: 210 women surveyed; 80% of them are unaware of the lower infant morbidity associated with a vaginal delivery, more than a half estimate an advantage of a cesarean section that it avoids pain, and a large percentage are unaware of the medical risks associated with cesarean sections. Conclusions: There is a high level of ignorance regarding the benefits, risks and consequences of the different delivery routes.

Factores sociales y demográficos asociados al embarazo y al embarazo repetido en mujeres adolescentes de Perú / Social and demographic factors associated with pregnancy and repeated pregnancy in adolescent women in Peru

OBJETIVO: Evaluar los factores sociales y demográficos asociados al embarazo y al embarazo repetido en mujeres adolescentes de Perú MÉTODO: Estudio transversal analítico realizado a partir de las encuestas de población ENDES 2009 a 2018 en Perú. Participaron mujeres adolescentes entre 12 y 19 años de edad. Se recogió información de condición de embarazo y características sociales y demográficas. Se aplicó la prueba de χ2 y se calculó la razón de prevalencia ajustada con su intervalo de confianza al 95% usando regresión de Poisson con varianza robusta. RESULTADOS: En el estudio se incluyeron 49 676 mujeres adolescentes. El 12,6% tuvieron un embarazo y el 5,1% tuvieron dos o más embarazos. Se evidenció asociación entre edad, región geográfica, origen étnico, nivel educativo, nivel económico y embarazo adolescente (p < 0,001). Los niveles educativo y económico inferiores presentaron una mayor razón de prevalencia de embarazo adolescente, siendo mayor incluso en situaciones de dos o más embarazos. CONCLUSIONES: En la población de mujeres adolescentes de Perú, el 17,7% estuvieron embarazadas y el 5,1% tuvieron embarazo repetido. Existe asociación entre embarazo adolescente y bajos niveles económico y educativo; esta asociación se incrementa en situaciones de embarazo repetido.

OBJECTIVE: To assess the social and demographic factors associated with pregnancy and repeated pregnancy in adolescent women in Peru. METHOD: Analytical cross-sectional study carried out from the ENDES population surveys 2009 to 2018 in Peru. Adolescent women between 12 and 19 years of age participated. Information on pregnancy status and number of children was collected, as well as social and demographic characteristics. The χ2 test was applied, the adjusted prevalence ratio with its 95% confidence interval was calculated using Poisson regression with robust variance. RESULTS: 49 676 adolescent women were included in the study. The 17.7% had one or more pregnancies and 5.1% two or more pregnancies. The analysis showed an association between geographic region, age, ethnic origin, educational level, economic level and adolescent pregnancy (p < 0.001). The lower levels of educational level and economic level presented a higher prevalence ratio of adolescent pregnancy, being higher even in situations of two or more pregnancies. CONCLUSIONS: In the population of adolescent women in Peru, 17.7% were pregnant and 5.1% had repeated pregnancy. Adolescent pregnancy is associated with low economic and educational levels; this association increases in situations of repeated pregnancy.

Correlates of exclusive breast feeding among nursing mothers attending child health clinic at a general hospital in Rivers State Nigeria

Background: Early initiation of breast feeding and feeding exclusively for six months have great implication for the survival, well-being and growth of new borne. Factors such as maternal age, occupation, religion, spouse age, spouse occupation, parity, antenatal care (ANC) attendance, mode of delivery (MOD) and birth order are significantly associated with exclusive breast feeding (EBF) Methodology: The study is a descriptive cross-sectional study conducted among nursing mothers attending child health clinic in General Hospital Bonny, in Bonny Island, Rivers State, Nigeria. All eligible nursing mother who presented at the clinic were enlisted for the study. Enlistment of eligible participants was done on every child welfare clinic day. Data was collected using a pretested, interviewer administered, structured questionnaire which was adapted and prepared in English Language. Categorical data was analyzed using multinomial logistic regression model with statistical significance set at 0.05. Result: Results from this study identified significant association between EBF and some maternal variables such as age, occupation and religion. Spouse age and occupation were significantly associated with EBF. ANC attendance, gestational age, MOD, parity and birth order were also significant variables associated with EBF. Conclusion: Maternal variables such as age, occupation, religion, parity, MOD, ANC attendance including spouse age and occupation significantly influence EBF of new borne.

The high rate of cervical cancer in Algeria and the absence of organized screening programs are well shown in this study, which aims to determine the prevalence of cervical cancer and describe the risk factors associated with this alarming prevalence. This retrospective study is based on data collected from medical records and A questionnaire was developed to assess the risk factors (such as: parity, age at first marriage, smoking, oral contraceptive, and Hormonal status) of cervical cancer among the participants. Face to Face interview were conducted with the participants. The result obtained from this study revealed that cervical cancer occupies the fourth place of cancer in the Wilaya of Ain Defla (4,71 %); the results confirm the effect of several risk factors such as early marriage age (below 20 years: 46.66 %), multiparity (53.33%), menopause (66.66 %); taking contraception (53.33%) and smoking in the development of this pathology. The adoption of an early and annual screening program in our region would be very important to us. In addition, the interest of annual screening is to raise women's awareness of this pathology, particularly in isolated regions. (

Age at childbirth and change in BMI across the life-course: evidence from the INCAP Longitudinal Study

Background: Parity has been associated with both short- and long-term weight gain in women. However, it is not clear if timing of parity across the reproductive age has different associations with BMI. Methods: To prospectively assess the association between age at childbirth and maternal change in BMI, we analyzed data from the ongoing INCAP Longitudinal Study, which started in 1969 in four villages in Guatemala. Cohort women (n=778) provided information on reproductive history and anthropometric measures were measured in 1988-89 (adolescence, 15 to 25y), 2002-04 (early adulthood, 26 to 36y) and 2015-17 (mid adulthood, 37 to 55y). We evaluated the associations of number of live births in the period preceding each study wave (1969-77 to 1988-89, 1988-89 to 2002-04 and 2002-04 to 2015-17) with BMI change in the same period using multivariable linear regression models. Results: Number of live births between 1988 and 89 and 2002-04 was positively associated with increased BMI, while there was not an association between number of live births and BMI in the other intervals. Women who had one, two, or three or more children between 1988 and 89 and 2002-04 had 0.90 (kg/m2, 95% CI: -0.55, 2.35), 2.39 (kg/m2, 95% CI: 1.09, 3.70) and 2.54 (kg/m2, 95% CI: 1.26, 3.82) higher BMI, respectively, than women who did not give birth in the same period. Conclusions: Our findings suggest that women who had three or more children during early adulthood gained more weight compared to women who had no children in the same period. In contrast, women who had children earlier or later in their reproductive lives did not gain additional weight compared to those who did not have children during that period. Childbirth may have different

Relações entre a saúde mental e a conjugalidade de gestantes primíparas / Relationship between mental health and conjugality of primiparous pregnant / Relación entre salud mental y la conyugalidad de embarazadas primíparas

Este estudo avaliou as relações entre variáveis sociodemográficas, saúde mental da mulher e conjugalidade durante a gestação. Participaram desta pesquisa correlacional 50 mulheres primíparas, que coabitavam com o genitor do bebê e que estavam no segundo ou terceiro trimestre de gestação do primeiro filho. Os sintomas de transtornos mentais comuns foram avaliados pelo Self-Reporting Questionnaire (SRQ-20) e os sintomas depressivos pelo Inventário Beck de Depressão (BDI-I). A conjugalidade foi avaliada com a Escala de Ajustamento Diádico. Os resultados de testes de correlação e de comparação de grupos mostraram que a presença de sintomas de transtornos mentais comuns e de depressão esteve associada a menor nível de ajustamento diádico. Discute-se a importância de identificar problemas na saúde mental da mulher e no ajustamento diádico durante a gestação, para favorecer o bem-estar da tríade mãe-pai-bebê na transição para a parentalidade.

This study evaluated the relation between sociodemographic variables and women's mental health and conjugality during pregnancy. Participated in this correlational research 50 primiparous women, who cohabited with the baby's father and were in the second or third trimester of their first child pregnancy. The symptoms of common mental disorders were evaluated by the Self-Report Questionnaire (SRQ-20) and the depressive symptoms by the Beck Depression Inventory (BDI-I). Conjugality was evaluated with the Dyadic Adjustment Scale. Results from correlations and group comparison tests showed that the presence of depressive symptoms and symptoms of common mental disorders were associated with lower levels of dyadic adjustment. The importance of identifying problems in women's mental health and dyadic adjustment during pregnancy is discussed in order to promote the well-being of the mother-father-baby triad at the transition to parenthood.

Este estudio evaluó las relaciones entre variables sociodemográficas, salud mental y conyugalidad de mujeres durante el embarazo. Participaron en este investigación correlacional 50 mujeres primíparas, viviendo con los padres del los bebés y estando en el segundo o tercer trimestre de embarazo del primer hijo. Los síntomas de trastornos mentales comunes fueron evaluados por el Cuestionario de Autoinforme (SRQ-20) y los síntomas de depresión por el Inventario de Depresión de Beck (IDB-I). La conyugalidad fue evaluada por la Escala de Ajuste Diádico. Los resultados de los testes de correlación y comparación de grupos muestraron que la presencia de síntomas depressivos y de trastornos mentales comunes se asoció a un menor nivel de ajuste diádico. Se discute la importancia de identificar problemas en la salud mental de las mujeres y en el ajuste diádico durante el embarazo para favorecer la tríada madre-padre-bebé en la transición para la parentalidad.

Recurrent preterm birth: data from the study "Birth in Brazil" / Prematuridade recorrente: dados do estudo "Nascer no Brasil"

ABSTRACT OBJECTIVE Describe and estimate the rate of recurrent preterm birth in Brazil according to the type of delivery, weighted by associated factors. METHODS We obtained data from the national hospital-based study "Birth in Brazil", conducted in 2011 and 2012, from interviews with 23,894 women. Initially, we used the chi-square test to verify the differences between newborns according to previous prematurity and type of recurrent prematurity. Sequentially, we applied the propensity score method to balance the groups according to the following covariates: maternal age, socio-economic status, smoking during pregnancy, parity, previous cesarean section, previous stillbirth or neonatal death, chronic hypertension and chronic diabetes. Finally, we performed multiple logistic regression to estimate the recorrence. RESULTS We analyzed 6,701 newborns. The rate of recurrence was 42.0%, considering all women with previous prematurity. Among the recurrent premature births, 62.2% were spontaneous and 37.8% were provider-initiated. After weighting by propensity score, we found that women with prematurity have 3.89 times the chance of having spontaneous recurrent preterm birth (ORaj = 3.89; 95%CI 3.01-5.03) and 3.47 times the chance of having provider-initiated recurrent preterm birth (ORaj = 3.47; 95%CI 2.59-4.66), compared to women who had full-term newborns. CONCLUSIONS Previous prematurity showed to be a strong predictor for its recurrence. Thus, expanding and improving the monitoring and management of pregnant women who had occurrence of prematurity strongly influence the reduction of rates and, consequently, the reduction of infant morbidity and mortality risks in the country.

RESUMO OBJETIVO Descrever e estimar a taxa de prematuridade recorrente no Brasil segundo o tipo de parto, ponderado pelos fatores associados. MÉTODOS Os dados foram obtidos do estudo nacional de base hospitalar "Nascer no Brasil", realizado em 2011 e 2012, a partir de entrevistas com 23.894 mulheres. Inicialmente foi utilizado o teste qui-quadrado para verificar as diferenças entre os recém-nascidos, segundo a prematuridade prévia e o tipo de prematuridade recorrente. Sequencialmente, aplicou-se o método de ponderação pelo escore de propensão para equilibrar os grupos de acordo com as seguintes covariáveis: idade materna, classificação socioeconômica, tabagismo durante a gravidez, paridade, cesárea anterior, natimorto ou óbito neonatal anterior, hipertensão crônica e diabetes crônica. Por último, foi realizada regressão logística múltipla para estimar a prematuridade recorrente. RESULTADOS Foram analisados 6.701 recém-nascidos. A taxa de prematuridade recorrente foi de 42,0%, considerando todas as mulheres com prematuridade prévia. Dentre os prematuros recorrentes, 62,2% foram espontâneos e 37,8% ocorreram por intervenção-obstétrica. Após a ponderação pelo escore de propensão, verificou-se que mulheres com prematuridade prévia têm 3,89 vezes a chance de terem prematuridade recorrente espontânea (ORaj = 3,89; IC95% 3,01-5,03) e 3,47 vezes a chance de terem prematuridade recorrente por intervenção obstétrica (ORaj = 3,47; IC95% 2,59-4,66), em comparação às mulheres que tiveram recém-nascidos termo completo. CONCLUSÕES A prematuridade prévia revelou-se um forte preditor para sua recorrência. Assim, ampliar e melhorar o monitoramento e manejo de gestantes com história de prematuridade impacta fortemente na redução das taxas e, consequentemente, na redução dos riscos de morbimortalidade infantil no país.

Introducción: El cáncer de endometrio, el cáncer de ovario y el cáncer cervicouterino son las neoplasias, dentro del cáncer del aparato reproductor femenino, que se consideran más frecuentes en la actualidad. La aparición de cáncer ginecológico en mujeres vírgenes demuestra que se deben consideran otras factores causales de la enfermedad, sin embargo, en nuestro país, no hay la suficiente evidencia de documentación sobre estos casos. El objetivo del presente estudio medir la prevalencia de cáncer de cuello uterino, útero y ovarios en mujeres vírgenes atendidas en un centro de referencia de Ginecología Oncológica de Guayaquil. Metodología: El estudio es observacional y transversal, se realizó en el Hospital de Especialidades Teodoro Maldonado Carbo, del Instituto Ecuatoriano de Seguridad Social, Guayaquil-Ecuador, de enero del 2013 al diciembre del 2017. Se incluyeron pacientes con cáncer cervicouterino, de útero y ovarios divididos en Grupo 1 (G1) Mujeres vírgenes y Grupo 2 (G2): Mujeres con vida sexual activa. Las variables fueron edad, órgano afectado, comorbilidades, antecedente familiar de cáncer, tipo histológico y muerte. La muestra fue no probabilística, tipo censo. Se utiliza estadística analítica, la muestra dividida en 2 grupos se compara usando Chi2. Se reporta Odds Ratio con intervalo de confianza del 95%. Resultados: En G1 fueron 44 casos y en G2 fueron 337 casos. Lo que representa una prevalencia de 11.55% (IC95% 11.38-11.71%). Cáncer de Ovario en G1 fue 29/44 casos (66%) versus 95/337 casos (28.2%) en G2 P<0.0001 con OR: 4.92 (2.53-9.60). Cáncer de endometrio en G1 13/44 casos (29.5%) versus 54/337 casos (16%) en G2, OR 2.20 (1.08-4.47) P=0.03. Cáncer cervical en G1 2/44 casos (4.5%) y en G2 188/337 casos (55.8%) OR 0.38 (0.009-0.159) P<0.0001. La mortalidad en G1 fue 30/44 casos en G2 fue 130/337 casos, OR 4.14 (2.12-8.08) P>0.0001. Conclusión: En mujeres sin antecedentes de vida sexual, existe mayor riesgo de cáncer de ovario y de endometrio y el riesgo de cáncer de cérvix se disminuye un 96%. La mortalidad de este grupo de mujeres se duplica por la mayor existencia de cáncer de ovario y endometrial.

Introduction: Endometrial cancer, ovarian cancer and cervical cancer are the neoplasias, within cancer of the female reproductive system, which are considered more frequent today. The appearance of gynecological cancer in virgin women shows that other causal factors of the disease must be considered, however, in our country, there is not enough documentary evidence on these cases. The objective of this study is to measure the prevalence of cervical, uterine and ovarian cancer in virgin women treated in a reference center for Gynecology Oncology in Guayaquil. Methodology: The study is observational and cross-sectional, it was carried out at the Teodoro Maldonado Carbo Specialties Hospital, of the Ecuadorian Social Security Institute, Guayaquil-Ecuador, from January 2013 to December 2017. Patients with cervical, uterine and cervical cancer were includ-ed. ovaries divided into Group 1 (G1) Virgin women and Group 2 (G2): Women with an active sexual life. The variables were age, affected organ, comorbidities, family history of cancer, histological type, and death. The sample was non-probabilistic, census type. Analytical statistics are used, the sample divided into 2 groups is compared using Chi2. Odds Ratio is reported with a confidence interval of 95%. Results: In G1 there were 44 cases and in G2 there were 337 cases. Which represents a prevalence of 11.55% (95% CI 11.38-11.71%). Ovarian cancer in G1 was 29/44 cases (66%) versus 95/337 cases (28.2%) in G2 P <0.0001 with OR: 4.92 (2.53-9.60). Endometrial cancer in G1 13/44 cases (29.5%) versus 54/337 cases (16%) in G2, OR 2.20 (1.08-4.47) P = 0.03. Cervical cancer in G1 2/44 cases (4.5%) and in G2 188/337 cases (55.8%) OR 0.38 (0.009-0.159) P <0.0001. Mortality in G1 was 30/44 cases in G2 it was 130/337 cases, OR 4.14 (2.12-8.08) P> 0.0001. Conclusion: In women with no history of sexual life, there is a greater risk of ovarian and endometrial cancer and the risk of cervical cancer is decreased by 96%. The mortality of this group of women doubles due to the increased existence of ovarian and endometrial cancer

Relação entre a diástase do músculo reto abdominal supraumbilical e infraumbilical e a contração dos músculos do assoalho pélvico de puérperas / Relationship between supra- and infraumbilical diastasis recti abdominis and pelvic floor muscles contraction of puerperal women

Objetivo: Avaliar a relação entre diástase músculo reto abdominal (DMRA) supra- e infraumbilical com a contração da musculatura do assoalho pélvico (MAP) de mulheres no pós-parto imediato, internadas em uma maternidade pública. Metodologia: Estudo transversal aprovado pelo Comitê de Ética em Seres Humanos (nº 1.674.698; CAA 6163616.8.0000.0096). Participaram 60 puérperas de baixo risco, assistidas nas enfermarias de uma maternidade. A DMRA foi avaliada pela palpação abdominal e graduada conforme a quantidade de polpas digitais. A contração da MAP foi avaliada por meio da inspeção visual. A correlação das variáveis foi realizada pelo teste de Spearman, com nível de significância em p<0,05. Resultados: 40 puérperas (66,7%) apresentaram DMRA supraumbilical e 23 participantes (38,4%) mantinham DMRA infraumbilical maior do que 2 polpas digitais. Cerca de 71,4% das puérperas contraíram MAP isoladamente e 12,7% contraíram MAP utilizando mecanismos compensatórios; 14,3% das puérperas não conseguiram realizar a contração. A DMRA supraumbilical está correlacionada com a contração da MAP com músculos acessórios de primíparas (p=0,03; r=-0,46); a sustentação da contração da MAP em multíparas (p=0,03; r=-0,43); e a ausência da contração da MAP (=0,03; r=0,35) e ao tempo de sustentação da contração (p=0,02; r=-0,40) em puérperas que realizaram parto vaginal. Conclusão: A presença da DMRA supraumbilical apresenta correlação com a função da MAP de puérperas de acordo com a paridade e a via de parto do último parto. (AU)

Aim: to analyze the relationship between supra- and infraumbilical diastasis recti abdominis (DRA) and pelvic floor musculature (PFM) contraction of women at immediate postpartum, admitted in a public maternity hospital. Methodology: Cross-sectional study approved by the Human Ethics Committee (nº 1.674.698; CAA 56163616.8.0000.0096). Sixty low-risk puerperal women attended at the maternity participated were included. DRA was assessed by abdominal palpation and graded according to number of digital pulps. PFM contraction was assessed by visual inspection. The correlation of variables was performed using the Spearman test, with a significance level of p <0.05. Results: 40 participants (66.7%) had supraumbilical DRA and 23 participants (38.4%) had infraumbilical DRA greater than 2 digital pulps. About 71.4% of women contract only PFM and 12.7% contract PFM using compensatory mechanisms; 14.3% of puerperal women were unable to perform a contraction. Supraumbilical DRA is correlated with PFM contraction and accessory muscles (p = 0.03; r = -0.46); to time of sustained PFM contraction in multiparous women (p = 0.03; r = -0.43); and absence of PFM contraction (= 0.03; r = 0.35) and the time of sustained PFM contraction (p = 0.02; r = -0.40) in puerperal women who underwent vaginal delivery. Conclusion: The presence of supraumbilical DRA correlates with PFM function according to the parity and the type of delivery. (AU)

Correlação entre disfunção do assoalho pélvico na ultrassonografia 3D dinâmica e parto vaginal, paridade e idade em mulheres com sintomas de defecação obstruída / Correlation between pelvic floor dysfunction on dynamic 3d ultrasound and vaginal delivery, parity, and age in women with obstructed defecation symptoms

ABSTRACT BACKGROUND: Few studies have investigated the constipation or obstructed defecation symptoms identified by using imaging, as dynamic three-dimensional ultrasound and correlate vaginal delivery, parity, and age. OBJECTIVE: The aim of this study was to assess the prevalence of pelvic floor dysfunctions in female patients with obstructed defection symptoms and to determine whether specific pelvic floor dysfunctions identified by dynamic three-dimensional ultrasonography (echodefecography) are correlated with vaginal delivery, parity, and age. The secondary goal is to report the prevalence of coexisting pelvic floor dysfunctions. METHODS: This is a retrospective cohort study including patients with obstructed defecation symptoms underwent echodefecographyto evaluate pelvic floor dysfunctions in the posterior compartment and correlate with vaginal delivery, parity, and age. RESULTS: Of 889 female: 552 (62%) had had vaginal delivery and 337 (38%) were nulliparous. The prevalence of dysfunctions identified by echodefecography (rectocele, intussusception, enterocele/sigmoidocele, and dyssynergia) was similar between the two groups and was not associated with number of deliveriesor age. However, the prevalence of sphincter defects showed higher rates in women with vaginal delivery and increased with the parity. Up to 33% of patients had coexisting dysfunctions. CONCLUSION: The prevalence of dysfunctions such as rectocele, intussusception, dyssynergia, and enterocele/sigmoidocele assessed by echodefecography in patients with obstructed defecation symptoms are found similar regardless of vaginal delivery, number of deliveries or stratified-age. In vaginal delivery, number of deliveries does impact on detection of sphincter defects and liability to fecal incontinence.

RESUMO CONTEXTO: Poucos estudos investigaram pacientes portadoras de defecação obstruída identificados por exames de imagens, como ultrassonografia tridimensional dinâmica, correlacionando parto vaginal, paridade e idade. OBJETIVO: O objetivo deste estudo foi avaliar a prevalência de disfunções do assoalho pélvico em pacientes do sexo feminino com sintomas de defecação obstruída e determinar se disfunções específicas do assoalho pélvico identificadas por ultrassonografia tridimensional dinâmica (ecodefecografia) estão correlacionadas com parto vaginal, paridade e idade. O objetivo secundário é relatar a prevalência de disfunções do assoalho pélvico coexistentes. MÉTODOS: Este é um estudo de coorte retrospectivo incluindo pacientes com sintomas de obstrução da defecação submetidas à ecodefecografia para avaliar disfunções do assoalho pélvico no compartimento posterior e correlacionar com parto vaginal, paridade e idade. RESULTADOS: De 889 mulheres: 552 (62%) tiveram parto vaginal e 337 (38%) eram nulíparas. A prevalência de disfunções identificadas pela ecodefecografia (retocele, intussuscepção, enterocele/sigmoidocele e dissinergia) foi semelhante entre os dois grupos e não foi associada ao número de partos ou à idade. No entanto, a prevalência de defeitos esfincterianos apresentou taxas mais elevadas em mulheres com parto vaginal e aumentou com a paridade. Até 33% dos pacientes apresentavam disfunções coexistentes. CONCLUSÃO: A prevalência de disfunções como retocele, intussuscepção, dissinergia e enterocele/sigmoidocele avaliada pela ecodefecografia em pacientes com sintomas de defecação obstruída são semelhantes independentemente do parto normal, número de partos ou idade estratificada. No parto vaginal, o número de partos tem impacto na detecção de defeitos esfincterianos e na possibilidade de incontinência fecal.

Cambios en el uso de anticonceptivos, embarazos no planificados e hijos en adolescentes chilenas entre 1997 y 2018 / Changes in the use of contraceptives, unplanned pregnancies and children in Chilean adolescents between 1997 and 2018

INTRODUCCIÓN: El embarazo en las adolescentes ha persistido como un problema de salud pública y social en Chile, afectando a las adolescentes más vulnerables y reflejando las desigualdades. OBJETIVO: Describir los cambios en el uso de anticonceptivos, embarazos no planificados e hijos en adolescentes chilenas entre 1997 y 2018. MÉTODO: Estudio ecológico de series temporales entre los años 1997 y 2018. Se midió la asociación entre variables sociodemográficas y efectividad del método anticonceptivo para los años 2006 y 2018, mediante la prueba estadística de Rao-Scott. Se estimaron tendencias del porcentaje de uso de métodos anticonceptivos según su eficacia y presencia de embarazos no planificados e hijos con modelos de regresión lineal (método de Prais-Winsten). RESULTADOS: Se observó un aumento en la frecuencia de adolescentes sexualmente activas y en el uso de anticonceptivos, especialmente píldoras e inyectables. La serie temporal de uso de anticonceptivos fue no estacionaria, la tendencia fue creciente (coeficiente: 4,59; intervalo de confianza del 95% [IC95%]: 3,43-5,74; p = 0,001), aumentando 4,59% cada 3 años. Las series de embarazos no planificados y tener hijos fueron series temporales no estacionarias y ambas presentaron una tendencia decreciente (coeficiente: −4,78; IC95%: −6,32 a −3,24; p = 0,002; y coeficiente: −3,93; IC95%: −6,18 a −1,68; p = 0,008), disminuyendo un 4,78% y un 3,93%, respectivamente, cada 3 años. CONCLUSIONES: El aumento en el uso de anticonceptivos en adolescentes ha ido unido a una importante disminución en los embarazos no planificados y los hijos en esta población.

INTRODUCTION: Adolescent pregnancy has persisted as a public and social health problem in Chile, affecting the most vulnerable adolescents and reflecting inequalities. OBJECTIVE: To describe the changes in the use of contraceptives, unplanned pregnancies and children in Chilean adolescents between 1997 and 2018. METHOD: Ecological study of time series between the years 1997 and 2018. The association between sociodemographic variables and the effectiveness of the contraceptive method for the years 2006 and 2018 was measured using the Rao-Scott statistical test. Trends in the percentage of use of contraceptive methods were estimated according to their efficacy and presence of unplanned pregnancies and children with linear regression models (Prais-Winsten method). RESULTS: An increase in the frequency of sexually active adolescents and the use of contraceptives, especially pills and injectables, was observed. The time series of contraceptive use was non-stationary, the trend was increasing (coefficient: 4.59; 95% confidence interval [95% CI]: 3.43-5.74; p = 0.001), increasing 4.59% every three years. The time series, unplanned pregnancies and having children were non-stationary time series, both showed a decreasing trend (coefficient: −4.78; 95%CI: −6.32 to −3.24; p = 0.002; and coefficient: −3.93; 95% CI: −6.18 to −1.68; p = 0.008), decreasing 4.78% and 3.93%, respectively, every 3 years. CONCLUSIONS: The increase in the use of contraceptives in adolescents has been linked to a significant decrease in unplanned pregnancies and children in this population.

Fatores sociodemográficos e clínicos associados à hemorragia pós-parto numa maternidade / Sociodemographic and Clinical Factors Associated with Postpartum Hemorrhage in a Maternity Ward / Factores sociodemográficos y clínicos asociados a la hemorragia posparto en una maternidad

Objetivo: investigar los factores sociodemográficos y clínicos asociados a la prevalencia de hemorragia posparto (HPP) en una maternidad de enseñanza. Materiales y métodos: estudio cuantitativo de corte transversal, en una maternidad de Salvador, Bahia, Brasil. En la recolección de los datos, se empleó formulario estandarizado que contenía datos sociodemográficos y clínicos de los historiales de 83 mujeres referentes al período de 2018. En los análisis, se utilizó el software STATA versión 14. Se realizó análisis bivariado, por medio de las pruebas de Pearson o exacto de Fisher. Además, regresión de Poisson con variación robusta en el análisis multivariado. Se estimaron razones de prevalencia (RP) y respectivos intervalos de confianza del 95 %. El nivel de significancia de las pruebas fue del 5 %. Resultados: la prevalencia de HPP fue del 38,6 % y del 25,6 % para atonía como causa. En el análisis bivariado, se evidenció asociación entre HPP y no lactancia en la primera hora de vida (p = 0,039). En el análisis multivariado, se identificó que mujeres multíparas tuvieron incremento en la prevalencia de HPP en casi dos veces (RP = 1,97). No lactar en la primera hora de vida aumentó esta prevalencia en más de cuatro veces (RP = 4,16). Conclusiones: monitorear multíparas durante la asistencia al parto e incentivar la lactancia materna en la primera hora de vida puede reducir la prevalencia de la HPP.

Objetivo: investigar os fatores sociodemográficos e clínicos associados à prevalência de hemorragia pós-parto (HPP) em uma maternidade escola. Materiais e métodos: estudo quantitativo de corte transversal, numa maternidade de Salvador, Bahia, Brasil. Na coleta de dados, utilizou-se formulário padronizado que continha dados sociodemográficos e clínicos dos prontuários de 83 mulheres referentes ao período de 2018. Nas análises, utilizou-se o software STATA versão 14. Foi conduzida análise bivariada, por meio dos testes de Pearson ou exato de Fisher. Realizou-se regressão de Poisson com variação robusta na análise multivariada. Foram estimadas razões de prevalência (RP) e respectivos intervalos de confiança de 95 %. O nível de significância dos testes foi de 5 %. Resultados: a prevalência de HPP foi de 38,6 % e de 25,6 % para atonia como causa. Na análise bivariada, evidenciou-se associação entre HPP e não amamentação na primeira hora de vida (p = 0,039). Na análise multivariada, identificou-se que mulheres multíparas tiveram incremento na prevalência de HPP em quase duas vezes (RP = 1,97). Não amamentar na primeira hora de vida aumentou essa prevalência em mais de quatro vezes (RP = 4,16). Conclusões: monitorizar multíparas durante a assistência ao parto e incentivar o aleitamento materno na primeira hora de vida pode diminuir a prevalência de HPP.

Objective: Checking the sociodemographic and clinical factors associated with the prevalence of postpartum hemorrhage (PPH) in a maternity school. Materials and methods: A quantitative cross-sectional study in a maternity hospital in Salvador, Bahia, Brazil. In data collection, we used a standardized form that contained sociodemographic and clinical data from the medical records of 83 women for the period of 2018. Stata version 14 software was used in the analyses. Bivariate analysis was conducted using Pearson's or Fisher's exact tests. Poisson regression was performed with robust variation in multivariate analysis. Prevalence ratios (PR) and respective 95 % confidence intervals were estimated. The significance level of the tests was 5 %. Results: The prevalence of PPH was 38.6 % and 25.6 % for atony as the cause. In the bivariate analysis, there was an association between PPH and non-breastfeeding in the first hour of life (p = 0.039). In the multivariate analysis, it was identified that multiparous women had an increase in the prevalence of PPH by almost twice (PR = 1.97). Not breastfeeding in the first hour of life increased this prevalence more than four times (PR = 4.16). Conclusions: Monitoring multiparous women during birth care and encouraging breastfeeding in the first hour of life may decrease the prevalence of PPH.

Risk Factors for Intrapartum Cesarean Section Delivery in Low-risk Multiparous Women Following at Least a Prior Vaginal Birth (Robson Classification 3 and 4)

Abstract Objective The aim of the present study was to evaluate the risk factors for cesarean section (C-section) in low-risk multiparous women with a history of vaginal birth. Methods The present retrospective study included low-risk multiparous women with a history of vaginal birth who gave birth at between 37 and 42 gestational weeks. The subjects were divided into 2 groups according to the mode of delivery, as C-section Group and vaginal delivery Group. Risk factors for C-section such as demographic characteristics, ultrasonographic measurements, smoking, weight gain during pregnancy (WGDP), interval time between prior birth, history of macrosomic birth, and cervical dilatation at the admission to the hospital were obtained fromthe charts of the patients. Obstetric and neonatal outcomes were compared between groups. Results The most common C-section indications were fetal distress and macrosomia (33.9% [n=77 and 20.7% [n=47] respectively). A bivariate correlation analysis demonstrated that mothers aged>30 years old (odds ratio [OR]: 2.09; 95% confidence interval [CI]: 1.30-3.34; p=0.002), parity >1 (OR: 1.81; 95%CI: 1.18-2.71; p=0.006), fetal abdominal circumference (FAC) measurement>360mm (OR: 34.20; 95%CI: 8.04 -145.56; p<0.001)) and<345mm (OR: 3.06; 95%CI: 1.88-5; p<0.001), presence of large for gestational age (LGA) fetus (OR: 5.09; 95%CI: 1.35-19.21; p=0.016), premature rupture of membranes (PROM) (OR: 1.52; 95%CI: 1-2.33; p=0.041), and cervical dilatation<5cm at admission (OR: 2.12; 95%CI: 1.34-3.34; p=0.001) were associated with the group requiring a C-section. Conclusion This is the first study evaluating the risk factors for C-section in low-risk multiparous women with a history of vaginal birth according to the Robson classification 3 and 4. Fetal distress and suspected fetal macrosomia constituted most of the Csection indications.
