RESUMO
Background: Women around the globe are increasingly engaging with pregnancy and parenting apps, almost becoming a routine part of the maternity experience. However, little is known about what perinatal women and health care professionals feel about those apps in Latin American countries, where the digital transformation has been slower but where digital technologies could also bridge gaps in access to quality health care. Methods: This study aimed to assess views towards pregnancy and parenting apps in perinatal women and perinatal health care professionals in Chile through an online survey. In perinatal women, we explored app use, what they value in the apps they use, and what an "ideal app" would be for them. In health professionals, we explored opinions about women using perinatal apps and what they think a perfect app for their clients would be. Results: The survey was completed by 451 perinatal women and 54 perinatal health care professionals. Results show that perinatal women in Chile frequently use perinatal apps, and they and health care professionals show a positive attitude towards them. The most valued attributes are information and monitoring of body changes during pregnancy, information and monitoring of the baby's development (in the uterus and after birth), information and tips on how to stay healthy, and having the possibility to interact with other women. Conclusions: Perinatal apps are accepted by perinatal women and health care professionals in Chile. Some needs for an "ideal app" emerged. Participants mentioned the need to address mental health, including the mental health of their partner, and the need for support during the transition to parenthood.
RESUMO
BACKGROUND: Recognizing the causes of stillbirths and their associated conditions is essential to reduce its occurrence. OBJECTIVE: To describe information on stillbirths in Brazil during the past decade. SEARCH STRATEGY: A literature search was performed from January 2010 to December 2020. SELECTION CRITERIA: Original observational studies and clinical trials. DATA COLLECTION AND ANALYSIS: Data were manually extracted to a spreadsheet and descriptive analysis was performed. RESULTS: A total of 55 studies were included; 40 studies (72.2%) used the official data stored by national public health systems. Most articles aimed to estimate the rate and trends of stillbirth (60%) or their causes (55.4%). Among the 16 articles addressing the causes of death, 10 (62.5%) used the International Classification of Diseases; most of the articles only specified the main cause of death. Intrauterine hypoxia was the main cause reported (ranging from 14.3% to 54.9%). CONCLUSION: Having a national system based on compulsory notification of stillbirths may not be sufficient to provide quality information on occurrence and, especially, causes of death. Further improvements of the attribution and registration of causes of deaths and the implementation of educational actions for improving reporting systems are advisable. Finally, expanding the investigation of contributing factors associated with stillbirths would create an opportunity for further development of prevention strategies in low- and middle-income countries such as Brazil.

Antecedentes: Hasta el momento actual, el abordaje bioético de los cuidados materno-perinatales se proyecta desde la visión integral de la salud bio - psico - social, la perspectiva de derechos humanos y el enfoque de género. En general, no se ha incorporado a los cuidados materno-perinatales la bioética ambiental, que surge de la perspectiva de la salud ambiental; integrando la ética global, la perspectiva de la consiliencia, el derecho al ambiente saludable y la ética ambiental. La actual situación de crisis global por la combinación de la Pandemia COVID 19 y la Sindemia Global, que caracterizaremos como Pan-sindemia, incrementa los riesgos y daños en el proceso reproductivo, sobre todo en las poblaciones vulneradas en sus derechos. Justificación: Es necesario minimizar el efecto de la Pan-sindemia en el proceso reproductivo. En la agenda global, la humanidad debe revertir las causas que provocan la Pan-sindemia. Mientras tanto, los profesionales y equipos de salud deben reformular su rol a la hora de los cuidados materno-perinatales, incorporando a la clínica el derecho a un ambiente saludable para la reproducción. Perspectivas: Las modificaciones en la práctica clínica de los equipos de salud sexual y reproductiva deben orientarse a: - incorporar la bioética ambiental a los cuidados materno-perinatales desde la formación hasta la práctica clínica - desarrollar un abordaje integral de los grandes síndromes obstétricos perinatales, la prematurez y la restricción de crecimiento, para minimizar el impacto de la Pan-sindemia en el proceso reproductivo humano.
Background: Until now, the bioethical approach to maternal perinatal care is projected from the integral vision of bio-psycho-social health, the perspective of Human Rights and the gender perspective. In general, environmental bioethics, which arises from the perspective of environmental health has not been incorporated into maternal-perinatal care with global ethics, the perspective of consilience, the right to a healthy environment and environmental ethics. The current global crisis situation due to the combination of the COVID 19 Pandemic and the Global Syndemic, characterized as Pan Syndemic, increases the risks and damages in the reproductive process, especially in populations violated in their rights. Justification: It is necessary to minimize the effect of the Pan Syndemic on the human reproductive process. On the global agenda, humanity must reverse the causes of the Pan Syndemic. Meanwhile, health professionals and teams must reformulate their role when it comes to maternal-perinatal care, incorporating into the clinic the right to a healthy environment for reproduction. Perspectives: Modifications in the clinical practice of sexual and reproductive health teams should be aimed at: incorporate environmental bioethics into maternal perinatal care from training to clinical practice; develop a comprehensive approach to major perinatal obstetric syndromes, prematurity and fetal growth restriction, to minimize the impact of the Pan Syndemic on the human reproductive process.
Até o momento, a abordagem bioética da atenção materna perinatal se projeta a partir da visão integral da saúde biopsicossocial, da perspectiva dos direitos humanos e da perspectiva de gênero. De modo geral, a bioética ambiental não foi incorporada à assistência materno-perinatal que surge na perspectiva da saúde ambiental; integrando a ética global, a perspectiva da consiliência, o direito ao ambiente saudável e a ética ambiental. A atual situação de crise global devido à combinação da Pandemia COVID 19 e da Sindemia Global, que caracterizaremos como Pan-sindêmica, aumenta os riscos e danos no processo reprodutivo, especialmente em populações cujos direitos são violados. Justificação: É necessário minimizar o efeito da Pan-sindemia no processo reprodutivo. Na agenda global, a humanidade deve reverter as causas que causam a Pan-sindemia. Nesse ínterim, os profissionais e equipes de saúde devem reformular seu papel no que se refere à assistência materno-perinatal, incorporando à clínica o direito a um ambiente saudável para a reprodução. Panorama: As modificações na prática clínica das equipes de saúde sexual e reprodutiva devem ter como objetivo: - incorporar a bioética ambiental ao cuidado perinatal materno, desde o treinamento até a prática clínica - desenvolver uma abordagem abrangente para as principais síndromes obstétricas perinatais, prematuridade e restrição de crescimento, para minimizar o impacto da Pan-sindemia no processo reprodutivo humano.

For more than a century, substantial racial and ethnic inequities in perinatal health outcomes have persisted despite technical clinical advances and changes in public health practice that lowered the overall incidence of morbidity. Race is a social construct and not an inherent biologic or genetic reality; therefore, racial differences in health outcomes represent the consequences of structural racism or the inequitable distribution of opportunities for health along racialized lines. Clinicians and scientists in obstetrics and gynecology have a responsibility to work to eliminate health inequities for Black, Brown, and Indigenous birthing people, and fulfilling this responsibility requires actionable evidence from high-quality research. To generate this actionable evidence, the research community must realign paradigms, praxis, and infrastructure with an eye directed toward reproductive justice and antiracism. This special report offers a set of key recommendations as a roadmap to transform perinatal health research to achieve health equity. The recommendations are based on expert opinion and evidence presented at the State of the Science Research Symposium at the 41st Annual Pregnancy Meeting of the Society for Maternal-Fetal Medicine in 2021. Recommendations fall into 3 broad categories-changing research paradigms, reforming research praxis, and transforming research infrastructure-and are grounded in a historic foundation of the advances and shortcomings of clinical, public health, and sociologic scholarship in health equity. Changing the research paradigm requires leveraging a multidisciplinary perspective on structural racism; promoting mechanistic research that identifies the biologic pathways perturbed by structural racism; and utilizing conceptual models that account for racism as a factor in adverse perinatal outcomes. Changing praxis approaches to promote and engage multidisciplinary teams and to develop standardized guidelines for data collection will ensure that paradigm shifts center the historically marginalized voices of Black, Brown, and Indigenous birthing people. Finally, infrastructure changes that embed community-centered approaches are required to make shifts in paradigm and praxis possible. Institutional policies that break down silos and support true community partnership, and also the alignment of institutional, funding, and academic publishing objectives with strategic priorities for perinatal health equity, are paramount. Achieving health equity requires shifting the structures that support the ecosystem of racism that Black, Brown, and Indigenous birthing people must navigate before, during, and after childbearing. These structures extend beyond the healthcare system in which clinicians operate day-to-day, but they cannot be excluded from research endeavors to create the actionable evidence needed to achieve perinatal health equity.

RESUMEN La mortalidad materna y perinatal representan un asunto prioritario de salud pública cuyo control reviste especial dificultad en zonas de frontera. Objetivos. Describir el comportamiento de la mortalidad materna y perinatal en los territorios fronterizos de Colombia, entre 1998 y 2016 y establecer su asociación con factores sociodemográficos, geográficos y de atención sanitaria. Métodos. Estudio observacional retrospectivo, basado en registros oficiales. Se calcularon las razones de mortalidad materna (RMM) y perinatal (RMP) para el período 1998-2016, identificando los puntos de inflexión mediante análisis de Joinpoint. Así mismo, se realizaron análisis bivariados y multivariados. Resultados. De los 54 municipios y 12 corregimientos de frontera, pertenecientes a 12 Departamentos, se obtuvieron 687 registros de mortalidad materna y 12,786 de mortalidad perinatal. Las razones observadas fueron 88 x 100,000 NV para la RMM y 16 x 1,000 NV para la RMP. La tendencia de estos tipos de mortalidad fue descendente, Los valores más altos de mortalidad perinatal se asociaron significativamente con la edad materna de 35 a 54 años, atención por régimen subsidiado, nivel educativo bajo, mujeres sin pareja, y embarazos múltiples. Conclusión. La mortalidad materna y perinatal registrada en los municipios fronterizos está por encima del promedio nacional.
ABSTRACT Abstract: Maternal and perinatal mortality is a priority public health issue that is particularly difficult to control in border areas. Objectives: To describe the behavior of maternal and perinatal mortality in the border territories of Colombia, between 1998 and 2016; and to establish its association with sociodemographic, geographic and health care factors. Methods: Retrospective observational study, based on official records. Maternal mortality ratio (MMR) and perinatal mortality ratio (RMP) were calculated for the period 1998-2016, identifying inflection points through Joinpoint analysis. Likewise, bivariate and multivariate analyses were performed. Results: From 54 municipalities and 12 borders townships belonging to 12 Departments, 687 records maternal mortality records and 12,786 perinatal mortality records were obtained. The ratios observed were 88 x 100,000 BA for MMR and 16 x 1,000 NV for PMR. The trend of these types of mortality was downward. The highest values of perinatal mortality were significantly associated with maternal age 35-54 years, care by subsidized regime, low educational level, women without a partner, and multiple pregnancies. Conclusion: Maternal and perinatal mortality registered in border municipalities is above the national average.
RESUMO
Health promotion and disease prevention are essential components of prenatal care. Maternal nutrient insufficiencies could negatively impact the morbidity and mortality of the mother-fetus pair as well as the health of the next generations. Although a healthy diet is usually sufficient to meet the increased nutrient needs, supplementation is part of routine care to ensure a healthy pregnancy and optimal fetal development. Currently, iron and folic acid supplementation is the only globally accepted recommendation for all pregnant women. However, there are vulnerable groups of women who could benefit from complementary individualized supplementation schemes. Recently, relevant information has been published related to the supplementation of single and multiple micronutrients with significant effects on maternal and fetal health, which could have implications in the clinical practice of health professionals. This review presents scientific evidence and the recommendations of different entities on the supplementation of iron, folic acid, calcium, vitamin D and multiple micronutrient supplementation during pregnancy.
La promoción de la salud y la prevención de enfermedades son componentes esenciales de la atención prenatal. Las insuficiencias de nutrimentos afectan negativamente la morbimortalidad del binomio madre-hijo, así como a la salud de las siguientes generaciones. Aunque una alimentación saludable generalmente es suficiente para cubrir las necesidades aumentadas de micronutrimentos, la suplementación es parte del cuidado habitual para garantizar un embarazo saludable y el desarrollo óptimo del producto. Actualmente la suplementación de hierro y ácido fólico es la única recomendación mundialmente aceptada para todas las mujeres embarazadas. Por otro lado, existen grupos de mujeres vulnerables que podrían beneficiarse de esquemas de suplementación individualizados complementarios. Recientemente se ha publicado información relevante relacionada con la suplementación de distintos micronutrimentos de forma individual y múltiple con efectos importantes en la salud materno-fetal, lo cual podría tener implicaciones en la práctica clínica de los profesionales de la salud. Esta revisión presenta la evidencia científica y las recomendaciones de distintos organismos sobre la suplementación de hierro, ácido fólico, calcio, vitamina D y suplementación múltiple de vitaminas y minerales durante el embarazo.

Background: Short interpregnancy interval (IPI) is associated with risk of adverse pregnancy outcomes; however, few studies have evaluated the role of depression as a risk factor for short IPI. Puerto Rican women in the United States experience disparities in adverse birth outcomes and have the highest birth rates. Methods: We analyzed the association between prenatal depressive symptoms and IPI in Proyecto Buena Salud, a prospective cohort of predominantly Puerto Rican women in Western Massachusetts (2006-2011). Depression was measured using the Edinburgh Postnatal Depression Scale (EPDS) in early, mid, and late pregnancy. We calculated follow-up time as the difference between the date of delivery of the index pregnancy and the last menstrual period of the subsequent pregnancy using medical records and billing data. We defined short IPI as ≤18 months. Results: Of 1262 eligible women, 35% (n = 440) had at least probable minor depression (EPDS scores ≥13) and 25% (n = 315) had probable major depression (EPDS scores ≥15). Participants were followed for a median of 3.7 years (interquartile range = 1.4-6.0 years) and 240 (20.6%) participants experienced a short IPI. After adjusting for risk factors, women with probable minor depression (adjusted odds ratio [aOR] = 1.39, 95% confidence interval [CI] = 1.02-1.88) and probable major depression (aOR = 1.42, 95% CI = 1.02-1.97) during pregnancy had increased odds of short IPI. Conclusions: Prenatal depressive symptoms were common in this Puerto Rican population and were associated with a modest increase in odds of short IPI. Further examination of the pathways through which mental health may affect IPI in vulnerable populations is warranted.

BACKGROUND: Studies comparing the outcome of spontaneous versus assisted reproductive technologies (ART) pregnancies report heterogeneous results. Despite the success of ART to overcome infertility, concern is growing regarding both its safety and its effect on maternal and child health. The objective of this study was to compare maternal and child-health outcomes after ART relative to natural conception. METHODS: A population-based birth cohort study was carried out among pregnant women expected to deliver in 2015 in Pelotas, southern Brazil. Maternal outcomes included pregnancy complications and gestational weight gain. Gestational age, weight, intrauterine growth restriction, length and head circumference, and 1-min and 5-min Apgar, as well as health problems at birth and breastfeeding were defined as offspring outcomes. Statistical analyses were performed using linear and logistic regression. G-formula was used to perform mediation analysis. RESULTS: The study included 4252 babies born by spontaneously pregnancies and 23 babies born after ART. Adjusted analyses showed that children conceived from ART presented lower means of gestational age (p = 0.001), birth weight (p = 0.002), length (p < 0.001), and head circumference at birth (p = 0.02). However, more than 90% of the effect of ART over these outcomes was mediated by multiple pregnancy. CONCLUSION: Our findings suggest that the possible negative effect on the child-health outcomes is due mainly to the higher incidence of multiple pregnancies and not because of ART. The reasons for the increase in adverse pregnancy outcomes associated with ART singleton pregnancies are still uncertain and warrants further research. Further large-population studies are needed to confirm these results.

OBJECTIVE: To address the essential characteristics of a network and aspects related to network sustainability. METHOD: A descriptive study based on a two-round Delphi survey was conducted from 2016 to 2018. Researchers participating in maternal and perinatal health networks were identified by searching PubMed for network-based publications and invited to complete a two-round Delphi questionnaire by email. RESULTS: Among 529 eligible researchers identified, 54 (10.2%) and 46 (8.7%) responses were received in the first and second rounds, respectively. A consensus on 13 of 21 [OK] questions, and 5 of 10 questions was achieved in the first and second rounds, respectively. The results indicated that a responsible leader is required, and both coordinators and members have a role in decision-making within the network. Good communication and periodic face-to-face meetings are key factors in sustainability and motivation. Rules for secure access to the network database and definition of authorship of scientific papers are essential. Mentioning the name of the network in publications is important for strengthening its activities and the obtainment of funds. CONCLUSION: Although operational characteristics of the network may differ according to setting and collaborators, homogeneous and essential network characteristics were identified.

Alma Ata is still in force in those experiences of comprehensive health care from all and for all that some countries have managed to implement, especially in the rural areas with populations affected by exclusion and poverty. Peru has several of them that find their roots in experiences previous to the 1978 Conference. It is interesting to confirm that many of these were initially dedicated to the care of pregnant women and newborns, and then they have translated their lessons learned to the care of the whole population.
Alma Ata sigue vigente en aquellas experiencias de Cuidado Integral de la Salud por todos y para todos que algunos países han logrado implementar, sobre todo en zonas rurales con poblaciones afectadas por la exclusión y la pobreza. El Perú detenta varias de ellas, que incluso encuentran sus raíces en experiencias previas a la Conferencia de 1978. Es interesante confirmar que muchas de estas se abocaron primero a la atención de las gestantes y recién nacidos, y luego han trasladado sus lecciones aprendidas al cuidado de toda la población.
RESUMO
Objectives To examine associations between depression and preterm birth and small-for gestational age (SGA) among women of predominantly Puerto Rican descent, a population who experiences disparities in adverse birth outcomes and one of the highest infant mortality rates in the United States. Methods Proyecto Buena Salud (PBS) was a prospective cohort study conducted from 2006 to 2011 at a large tertiary care center in Western Massachusetts. Caribbean Islander (i.e., Puerto Rican and Dominican Republic) women were interviewed in early, mid and late pregnancy. Among 1262 participants, associations between depression, assessed using the Edinburgh Postnatal Depression Scale, and risk of preterm birth and small-for-gestational age (SGA) were evaluated. Results Women with at least probable minor depression [odds ratio (OR) = 1.77 (95% confidence interval (CI) = 1.02, 3.07)] or probable major depression [OR = 1.82 (95% CI = 1.01, 3.25)] in mid-pregnancy had an increased risk of SGA compared to non-depressed women in adjusted analyses. Borderline significant associations were observed between increasing levels of depressive symptom scores in early and mid-pregnancy [OR = 1.05 (95% CI = 1.00, 1.11) and OR = 1.04 (95% CI = 1.00, 1.09), respectively] and each additional trimester of exposure to probable major depression across mid- to late pregnancy [OR = 1.66 (95% CI = 1.00, 2.74)] and SGA. Late pregnancy depression was not associated with SGA; depression during pregnancy was not associated with preterm birth. Conclusions for Practice In this population of predominantly Puerto Rican women, mid-pregnancy depression increased risk for SGA. Findings can inform culturally appropriate, targeted interventions to identify and treat pregnant women with depression.

BACKGROUND: Antenatal depression (AD) is a major public health issue but evidence regarding its prevalence and associated factors in low and middle-income countries (LMICs) is limited. The aim of the study was to estimate the prevalence and identify risk factors for AD among Brazilian pregnant women. METHODS: All women living in the urban area of the city of Pelotas, Southern Brazil, with confirmed pregnancy and estimated delivery date in the year 2015, were invited to take part. Eligible pregnant women were recruited from health services. Symptoms of antenatal depression were assessed using the Edinburgh Postnatal Depression Scale (EPDS) by face-to-face interviews. A cutoff-point of 13 or more was used to define probable AD. RESULTS: EPDS scores were available for 4130 women. The prevalence of AD was 16% (95%CI 14·9-17·1). After adjustment for potential confounders, the factors most strongly associated with higher EPDS scores were a previous history of depression (PR 2·81; 95%CI 2·44-3·25), high parity (PR 1·72; 95%CI 1·38-2·15 - ≥2 children vs. 1 child) and maternal education (PR 5·47; 95%CI 4·22-7·09 - 0-4 vs. ≥12 years of formal education). LIMITATIONS: EPDS was administered through face-to-face interviews rather than questionnaires and some women may have felt uncomfortable reporting their symptoms leading to underreporting and consequently underestimation of the prevalence found. CONCLUSION: AD prevalence is substantially higher in Brazil than in high-income countries (HICs) but similar to other LMICs. Our study identified relevant risk factors that may be potential targets to plan interventions, particularly a history of depression.

Few studies are available about racial inequalities in perinatal health in Brazil and little is known about whether the existing inequality is due to socioeconomic factors or to racial discrimination per se. Data regarding the Ribeirão Preto birth cohort, Brazil, whose mothers were interviewed from June 1, 1978 to May 31, 1979 were used to answer these questions. The perinatal factors were obtained from the birth questionnaire and the ethnic data were obtained from 2063 participants asked about self-reported skin color at early adulthood (23-25 years of age) in 2002/2004. Mothers of mulatto and black children had higher rates of low schooling (ú4 years, 27.2 and 38.0 percent) and lower family income (ú1 minimum wage, 28.6 and 30.4 percent). Mothers aged less than 20 years old predominated among mulattos (17.0 percent) and blacks (14.0 percent). Higher rates of low birth weight and smoking during pregnancy were observed among mulatto individuals (9.6 and 28.8 percent). Preterm birth rate was higher among mulattos (9.5 percent) and blacks (9.7 percent) than whites (5.5 percent). White individuals had higher rates of cesarean delivery (34.9 percent). Skin color remained as an independent risk factor for low birth weight (P < 0.001), preterm birth (P = 0.01), small for gestational age (P = 0.01), and lack of prenatal care (P = 0.02) after adjustment for family income and maternal schooling, suggesting that the racial inequalities regarding these indicators are explained by the socioeconomic disadvantage experienced by mulattos and blacks but are also influenced by other factors, possibly by racial discrimination and/or genetics.

We describe three birth cohort studies, respectively carried out in 1978/79 and 1994 in Ribeirão Preto, a city located in the most developed region of Brazil, and in 1997/98 in São Luís, a city located in a less developed region. The objective of the present report was to describe the methods used in these three studies, presenting their history, methodological design, objectives, developments, and difficulties faced along 28 years of research. The first Ribeirão Preto study, initially perinatal, later encompassed questions regarding the repercussions of intrauterine development on future growth and chronic adult diseases. The subjects were evaluated at birth (N = 6827), at school age (N = 2861), at the time of recruitment for military service (N = 2048), and at 23/25 years of age (N = 2063). The study of the second cohort, which started in 1994 (N = 2846), permitted comparison of aspects of perinatal health between the two groups in the same region, such as birth weight, mortality and health care use. In 1997/98, a new birth cohort study was started in São Luís (N = 2443), capital of the State of Maranhão. The 1994 Ribeirão Preto cohort and the São Luís cohort are in the second phase of joint follow-up. These studies permit comparative temporal analyses in the same place (Ribeirão Preto 1978/79 and 1994) and comparisons of two contrasting populations regarding cultural, economic and sociodemographic conditions (Ribeirão Preto and São Luís).
