O uso de métodos contraceptivos hormonais em pacientes com asma: repercussões clínicas / The use of hormonal contraceptives methods in patients with asthma: clinical repercussions

Objetivo: Analisar o uso dos contraceptivos hormonais em mulheres com asma e a escolha desses métodos contraceptivos para essa população, com avaliação de eventuais repercussões sobre novos episódios de asma e sibilos. Métodos: Foram selecionados estudos longitudinais, ensaios clínicos, revisões sistemáticas e metanálises. As plataformas consultadas foram PubMed, Embase, Cochrane e SciELO, com a utilização dos descritores: "contracepção", "contracepção hormonal", "sistema intrauterino liberador de levonorgestrel" e "asma". Resultados: Dois grandes estudos demonstraram que o uso de contraceptivos hormonais esteve associado à redução do risco de novos episódios de asma. Uma revisão sistemática concluiu que os resultados para o uso de contraceptivos hormonais para mulheres com asma foram mistos, com aumento ou redução dos seguintes riscos: novo episódio de asma e aumento da frequência das crises e dos sibilos. O uso da contracepção hormonal em pacientes obesas portadoras de asma é controverso. Conclusão: Os resultados para o uso de contraceptivos hormonais em mulheres com asma são inconsistentes, com relatos de aumento ou de redução do risco de novos episódios. O uso do método contraceptivo deve ser discutido individualmente, levando-se em consideração outros fatores de risco associados e o desejo da mulher. A paciente deverá ser orientada se houver piora dos sintomas clínicos de asma na vigência do uso de qualquer método contraceptivo hormonal.

Objective: To analyze the use of hormonal contraceptives in women with asthma and the choice of this contraceptive method for this population, evaluating possible repercussions on new episodes of asthma and wheezing. Methods: Longitudinal studies, clinical trials, systematic reviews and meta-analyses were selected. Platforms consulted: PubMed, Embase, Cochrane, SciELO, using the descriptors: "contraception", "hormonal contraception", "levonorgestrel-releasing intrauterine system" and "asthma". Results: Two large studies demonstrated that the use of hormonal contraceptives was associated with a reduced risk of new episodes of asthma. A systematic review concluded that the results for the use of hormonal contraceptives for women with asthma were mixed, with increased or decrease in the following risks: new asthma episodes, increased frequency and wheezing. The use of hormonal contraception in obese patients with asthma is controversial. Conclusion: The results for the use of hormonal contraceptives in women with asthma are inconsistent, with reports of increased or reduced risk of new episodes. The use of the contraceptive method should be discussed individually, taking into account other associated risk factors and the woman's desire. The patient will be advised if there is a worsening of the clinical symptoms of asthma while using any hormonal contraceptive method.

Trend of age of menarche among Chinese Han girls aged 9 to 18 years from 2010 to 2019 / 中华预防医学杂志

Objective: To analyze the trends of the age of menarche among Chinese Han girls aged 9 to 18 years from 2010 to 2019. Methods: Data were extracted from the Chinese National Surveys on Students' Constitution and Health in 2010, 2014 and 2019. A total of 253 037 Han girls aged 9 to 18 years with complete data on menarche were selected in this study. They were asked one-on-one about their menstrual status, age and residence information. The median age of menarche was estimated by probability regression. U tests were used to compare the difference in median age at menarche in different years. Results: The median age at menarche (95%CI) among Chinese Han girls was 12.47 (12.09-12.83) years in 2010, 12.17 (11.95-12.38) years in 2014 and 12.05 (10.82-13.08) years in 2019, respectively. Compared with that in 2010, the median age at menarche in 2019 decreased by 0.42 years (U=-77.27, P<0.001). The annual average changes were -0.076 years from 2010 to 2014 (U=-57.19, P<0.001) and -0.023 years from 2014 to 2019 (U=-21.41, P<0.001), respectively. The average annual changes in urban areas in the periods of 2010 to 2014 and 2014 to 2019 were -0.071 years and 0.006 years, respectively, while those in rural areas were -0.082 years and -0.053 years, respectively. The average annual changes in the regions of north, northeast, east, south central, southwest and northwest were -0.064, -0.099, -0.091, -0.080, -0.096 and -0.041 years in the period of 2010 to 2014 and 0.001, -0.040, -0.002, -0.005, -0.043 and -0.081 years in the period of 2014 to 2019. Conclusion: The age of menarche among Chinese Han girls aged 9 to 18 years shows an advanced trend from 2010 to 2019, and the trends in urban and rural areas and different regions have different characteristics.

Secular trends of age at menarche and age at menopause in women born since 1951 from a county of Shandong Province, China / 北京大学学报(医学版)

OBJECTIVE@#To describe the secular trends of age at menarche and age at natural menopause of women from a county of Shandong Province.@*METHODS@#Based on the data of the Premarital Medical Examination and the Cervical Cancer and Breast Cancer Screening of the county, the secular trends of age at menarche in women born in 1951 to 1998 and age at menopause in women born in 1951 to 1975 were studied. Joinpoint regression was used to identify potential inflection points regarding the trend of age at menarche. Average hazard ratios (AHR) of early menopause among women born in different generations were estimated by performing multivariate weighted Cox regression.@*RESULTS@#The average age at menarche was (16.43±1.89) years for women born in 1951 and (13.99±1.22) years for women born in 1998. The average age at menarche was lower for urban women than that for rural women, and the higher the education level, the lower the average age at menarche. Joinpoint regression analysis identified three inflection points: 1959, 1973 and 1993. The average age at menarche decreased annually by 0.03 (P < 0.001), 0.08 (P < 0.001), and 0.03 (P < 0.001) years respectively for women born during 1951-1959, 1960-1973, and 1974-1993, while it remained stable for those born during 1994-1998 (P=0.968). As for age at menopause, compared with women born during 1951-1960, those born during 1961-1965, 1966-1970 and 1971-1975 showed a gradual decrease in the risk of early menopause and a tendency to delay the age at menopause. The stratified analysis presented that the risk of early menopause gradually decreased and the age of menopause showed a significant delay among those with education level of junior high school and below, but this trend was not obvious among those with education level of senior high school and above, where the risk of early menopause decreased and then increased among those with education level of college and above, and the corresponding AHRs were 0.90 (0.66-1.22), 1.07 (0.79-1.44) and 1.14 (0.79-1.66).@*CONCLUSION@#The age at menarche for women born since 1951 gradually declined until 1994 and leveled off, with a decrease of nearly 2.5 years in these years. The age at menopause for women born between 1951 and 1975 was generally delayed over time, but the trend of first increase and then decrease was observed among those with relatively higher education levels. In the context of the increasing delay in age at marriage and childbearing and the decline of fertility, this study highlights the necessity of the assessment and monitoring of women' s basic reproductive health status, especially the risk of early menopause.

Fatores associados à idade da menopausa natural na coorte Elsa-Brasil / Factors associated with age at natural menopause in the Elsa-Brasil cohort

Introdução: No Brasil, a média etária da menopausa está entre 50 a 51,2 anos. Quando precoce, a menopausa se associa ao maior risco para doenças cardiovasculares, diabetes mellitus tipo 2 e osteoporose, entre outras doenças. Características sociodemográficas, hábitos de vida e fatores reprodutivos podem interferir na idade da menopausa natural, porém existem poucos estudos sobre essas relações no contexto brasileiro. Objetivo: Analisar os fatores associados à idade da menopausa natural em mulheres participantes do Estudo Longitudinal de Saúde do Adulto ELSA ­ Brasil, na primeira (2008 ­ 2010) e segunda visita (2012 ­ 2014). Metodologia: Estudo transversal, com dados da primeira (2008-2010) e segunda (2012-2014) visita do Elsa-Brasil. Foram elegíveis para participar deste estudo todas as 3.538 mulheres com relato de menopausa natural durante a 1ª ou 2ª visita ao ELSA. O desfecho do estudo foi a idade da menopausa natural (variável contínua). Variáveis explicativas: características sociodemográficas (idade, renda, escolaridade, raça/cor), reprodutivas (idade da menarca, histórico de gestação número de partos e abortos, duração do ciclo menstrual, uso de anticoncepcional), hábitos de vida (tabagismo, uso de álcool, consumo diário de frutas e verduras, atividade física), variáveis de saúde (obesidade, diabetes, hipertensão). A associação entre essas variáveis explicativas e o desfecho foi feita por regressão linear múltipla. Resultados: A média de idade da menopausa natural foi 49,07 anos. Encontramos que, quanto menor a escolaridade, menor a média da idade da menopausa (Fundamental incompleto versus Ensino Superior: ß -1.26; IC95%-1.93; -0.59; Fundamental versus Ensino Superior: ß-1.19; IC95%-1.79; -0.60; Ensino Médio versus Ensino Superior: ß-0.81; IC95%-1.16; -0.47). Adicionalmente, encontramos menores médias da idade da menopausa entre mulheres que reportaram raça/cor da pele parda (ß:-0.43; IC95%-0.80; -0.06) e indígena (ß:-1.71; IC95% -3.12; -0.30), quando comparadas às mulheres brancas. As tabagistas também apresentaram menor média de idade da menopausa (ß:-0.84; IC95%-1.29; - 0.39), em relação às que reportaram nunca ter fumado. Observamos também que mulheres com maior número de gestações apresentaram maior média de idade da menopausa quando comparadas às mulheres com nenhuma gestação (2 gestações ß:0.46; IC95% 0.01; 0.93, 3 gestações ß:1.01; 0.53;1.50, 4 ou mais ß:0.93; IC95% 0.45;1.41 em relação a nenhuma gestação). Por fim, também encontramos que, enquanto mulheres com ciclos menstruais curtos (<25 dias) foram associadas à menor idade da menopausa (ß -0.58; IC95% -1.15; -0.02), mulheres com ciclos menstruais longos (>35 dias) foram associadas à maior idade da menopausa (ß: 2.24; IC95% 1.43; 3.04), quando comparadas às mulheres com ciclos de 25-35 dias. Conclusão: Menor escolaridade, tabagismo, cor da pele parda e indígena e menor ciclo menstrual associaram-se a menores médias de idade da menopausa natural, enquanto o maior ciclo menstrual e o maior número de gestações associaram-se positivamente ao desfecho. Este estudo soma-se a outros estudos nacionais sobre o tema e tem potencial para auxiliar a compressão acerca de fatores relacionados à idade da menopausa e, consequentemente, ser fonte de evidências para formulação de políticas mais abrangentes na saúde da mulher, com a intenção de minimizar os impactos que podem ser gerados na idade da menopausa e, consequentemente, nas comorbidades advindas de uma menopausa precoce.

Introduction: In Brazil, the average age of menopause is between 50 and 51.2 years. When early, menopause is associated with a higher risk for cardiovascular diseases, type 2 diabetes mellitus and osteoporosis, among others. Sociodemographic characteristics, life habits and reproductive factors can interfere with the age of natural menopause, but there are few studies on these relationships in the Brazilian context. Objective: To analyze factors associated with age at natural menopause in women participating in the ELSA Adult Health Longitudinal Study ­ Brazil, at the first (2008 ­ 2010) and second visit (2012 ­ 2014). Methodology: Cross-sectional study, with data from the first (2008-2010) and second (2012-2014) visit in Elsa-Brasil. A total of 3,538 women were studied, considering the age of natural menopause as outcome. Explanatory variables: sociodemographic characteristics (age, income, education, race/color), reproductive characteristics (age at menarche, history of pregnancy - number of deliveries and abortions, duration of the menstrual cycle, use of contraceptives), life habits (smoking, use alcohol consumption, daily consumption of fruits and vegetables, physical activity), health variables (obesity, diabetes, hypertension, symptoms of depression). The association between these variables and the outcome was analyzed by multiple linear regression. Results: The mean age of natural menopause was 49.07 years. The following variables were associated with menopause age: low schooling (High school: ß-0.81; 95%CI-1.16;-0.47, Elementary school: ß-1.19; 95%CI-1.79;-0.60, Incomplete elementary school: ß -1.26;95%CI -1.93, -0.59) in relation to higher education; brown and indigenous skin color in relation to white skin color (ß: -0.43; 95%CI-0.80;-0.06 and ß:-1.71; 95%CI -3.12;-0.30); smoking (ß:-0.84;CI95%-1.29;- 0.39) in relation to never having smoked; number of pregnancies (2 pregnancies ß:0.46; 95%CI 0.01; 0.93, 3 pregnancies ß:1.01; 0.53;1.50, 4 or more ß:0.93; 95%CI 0.45;1.41); in relation to no pregnancy; and menstrual cycle <25 days and >35 days (ß -0.58; 95%CI -1.15; -0.02, ß: 2.24; 95%CI 1.43; 3.04), compared to 25-35 days. Conclusion: Lower schooling, smoking, brown and indigenous skin color and shorter menstrual cycle were associated with lower mean age at natural menopause, while longer menstrual cycle and higher number of pregnancies were positively associated with the outcome. This study adds to other national studies on the subject and is able to help in clinical practice when health professionals have access to quality data, in the discussion and formulation of more comprehensive women's health policies that work on associated factors with the intention of minimizing the impacts that can be generated in the age of menopause and consequently in the comorbidities arising from an early menopause.

Conclusiones: La anemia constituye un problema multifactorial con alta prevalencia en las adolescentes estudiadas. Se evidenció la presencia de varios factores de riesgo, como hábitos alimentarios inadecuados, malnutrición tanto por defecto como por exceso, menstruaciones abundantes y ausencia de profilaxis para la enfermedad(AU)

Introduction: Adolescence is a stage of life with many changes and greater vulnerability to health risks. Among the main health problems are nutritional disorders and, among them, deficiency anemia. Objectives: To determine the prevalence of anemia in female adolescents in a medical office, and to describe the clinical-epidemiological characteristics of anemic adolescents and the presence of some factors that could influence its occurrence. Methods: Was carried out a descriptive, observational and cross-sectional study in 76 female adolescents between 11 and 19 years old, from the Family Medical Clinic No. 16 of the Ramón López Peña Polyclinic, Santiago de Cuba, between March and December 2020. The sample was intentional, made up of 45 anemic adolescents. Were studied age, intensity of anemia, nutritional evaluation, toxic habits, age of menarche and characteristics of menstruation, eating habits, among others. Results: The prevalence of iron deficiency anemia was 59.2 percent . The mean age was 14.89 years; 15.6 percent of anemic adolescents were underweight and 20 percent were overweight or obese; 73.3 percent had bad eating habits, only 24.4 percent received prophylaxis with ferrous salts. In addition, heavy menstrual bleeding (22.3 percent ) and menarche before the age of 11 (20 percent ) stood out. Conclusions: Anemia constitutes a multifactorial problem with a high prevalence in the studied adolescents. The presence of several risk factors was evidenced, especially inadequate eating habits, malnutrition both by default and by excess, heavy menstruation and the absence of prophylaxis for the disease(AU)

Abnormal Uterine Bleeding in Adolescence: When Menarche Reveals other Surprises / Hemorragia uterina anormal na adolescência: Quando a menarca revela outras surpresas

Abstract Introduction Abnormal uterine bleeding is more frequent in adolescence. Although, most commonly, it has a non-structural etiology, it may be due to any cause described. Clinical case A 12-year-old adolescent, with no relevant personal history, menarche 1 month before, was observed in the emergency department for severemenstrual bleeding with progressive worsening, and hemodynamic repercussion in need of transfusion support. Physiological ovulatory dysfunction associated with possible previously unknown coagulopathy was considered to be the most likely diagnosis and medical treatment was initiated. Without response, the patient was submitted to sedated observation and uterine aspiration, which ultimately led to the diagnosis of a Burkitt Lymphoma. Discussion Although structural causes, and particularly malignancy, whether gynecological or not, are a rare cause of abnormal uterine bleeding in this age group, they must be considered, thus enhancing the fastest and most appropriate treatment.

Resumo Introdução A hemorragia uterina anormal é mais frequente na adolescência. Apesar de maioritariamente de etiologia não estrutural, pode dever-se a qualquer causa descrita. Caso clínico Adolescente de 12 anos, sem antecedentes pessoais relevantes, com menarca há 1 mês, observada no serviço de urgência por hemorragia menstrual grave com agravamento progressivo e repercussão hemodinâmica com necessidade de suporte transfusional. Foi colocada a hipótese de disfunção ovulatória fisiológica associada a eventual coagulopatia desconhecida previamente e foi instituído tratamento médico. Por ausência de resposta a tratamento médico, foi submetida a observação sob sedação e aspiração uterina que evidenciou tratar-se de um Linfoma de Burkitt. Discussão Apesar de as causas estruturais, e particularmente as neoplasias, do foro ginecológico ou não, serem uma causa rara de hemorragia uterina anormal nesta faixa etária, elas devem ser levadas em consideração potenciando assim um tratamento mais célere e adequado.

Gynecological/Obstetric Background and Rheumatoid Arthritis: A Cross-sectional Study in Brazilian Patients / Antecedentes ginecológicos/obstétricos e artrite reumatoide: Um estudo transversal em pacientes brasileiros

Abstract Objective To study a sample of rheumatoid arthritis (RA) patients for their gynecological/obstetric history and compare them to controls to determine their influences on number of pregnancies, menarche, menopause and reproductive years following RA onset. Methods This is a cross-sectional study of 122 RA patients and 126 controls. Patients and controls were questioned about age of menarche, age of menopause, number of pregnancies and abortions. Reproductive years were calculated as the difference between age at menopause and age at menarche. For comparison, we used the Mann-Whitney, unpaired t, chi-squared, and Spearman tests. The adopted significance was 5%. Results In the RA patients with disease beginning in the postmenopausal years, the period of reproductive years (age at menopause - age of menarche) showed a positive correlation with age at disease onset (rho=0.46; 95% confidence interval [CI]=0.20- 0.55 with p=0.0008). The number of pregnancies was higher in patients with postmenopausal disease onset when compared with those with premenopausal disease onset (median of 3 with interquartile range [IQR]=2-4 versus median of 2 with IQR=1-3; p=0.009), and RA patients had more pregnancies than controls (p=0.0002). Conclusion The present study shows that, in our population, the duration of reproductive years and the number of pregnancies are linked to the onset of RA.

Resumo Objetivo Estudar uma amostra de pacientes com artrite reumatoide (AR), com investigação da história ginecológica e obstétrica, comparando-a com controles, visando conhecer suas influências no número de gestações, menarcas, menopausa e anos reprodutivos no início da AR. Métodos Trata-se de um estudo transversal de 122 pacientes com AR e 126 controles. Pacientes e controles foram questionados sobre idade da menarca, idade da menopausa, número de gestações e abortos. Os anos reprodutivos foram calculados com a diferença entre a idade da menopausa e a idade da menarca. Para comparação, foram utilizados Mann Whitney, Teste t não pareados, Teste qui-quadrado e teste de Spearman. A significância adotada foi de 5%. Resultados Nas pacientes comAR e início da doença na pós-menopausa, o período de anos reprodutivos (idade da menopausa - idade da menarca) apresentou correlação positiva com a idade de início da doença (rho=0,46; intervalo de confiança de 95% [IC95%]=0,20-0,55 com p=0,0008). O número de gestações foi maior nas pacientes cominício da doença no período pós-menopausa quando comparadas às pacientes em pré-menopausa (mediana de 3 comintervalo interquartil [IIQ]=2-4 versusmediana de 2 com IIQ=1-3; p=0,009). Nas pacientes com AR, foi observado ummaior número de gestações do que no grupo controle (p=0,0002). Conclusão O presente estudo mostra que, em nossa população, a diminuição dos anos reprodutivos e o alto número de gestações estão relacionados ao surgimento da AR.

Ultrasound findings of pubertal development in girls with cystic fibrosis and their association with clinical outcomes and Tanner staging

ABSTRACT Objective: Patients with cystic fibrosis (CF) have a high incidence of pubertal and growth delay. In girls with CF, pubertal delay has an important psychological impact. Still, only a few studies have explored the occurrence of pubertal delay in girls with CF. The aims of this study were to compare the pubertal development of girls with CF compared with healthy controls regarding Tanner staging and pelvic ultrasound and, in girls with CF, correlate the findings with those of spirometry, body mass index, Shwachman-Kulczycki score (SKS), and genotyping. Subjects and methods: This was a cross-sectional, case-control study including 35 girls with CF aged 6-17 years and following up at the Pediatric Pulmonology Outpatient Clinic of a tertiary hospital. These patients were compared with 59 healthy controls who had undergone pelvic ultrasound as part of another study conducted by the same group. Girls with CF were consecutively enrolled in the study during their annual routine check-up visit. Data collected in the CF group included spirometry and anthropometric results, SKS values, bone age, occurrence of current cystic fibrosis-related diabetes (CFRD) and Pseudomonas aeruginosa colonization, history of meconium ileus, genotype, ultrasound parameters, and Tanner stage. Results: Pelvic ultrasound findings and Tanner stage reflected less pubertal development in girls with CF compared with healthy controls. Pubertal stage in patients with CF who presented CFRD (3.17 ± 1.16), had chronic colonization by Pseudomonas aeruginosa (3.10 ± 1.10), or were homozygous for the F508del mutation (1.91 ± 1.30) was more delayed than in controls (3.41 ± 1.41). Tanner stage correlated with age at menarche, bone age, and anthropometric and ultrasound data. Conclusions: Girls with CF presented a delay in pubertal development evaluated by Tanner stage and ultrasound parameters, which was more evident in the presence of comorbidities.

Factores de riesgo asociados al cáncer de mama / Risk Factors Associated with Breast Cancer

RESUMEN Introducción: El cáncer de mama es el tumor maligno más frecuente entre las mujeres de todo el mundo. Considerando los dos sexos, es el segundo en frecuencia después del cáncer de pulmón. En Cuba, sigue siendo la neoplasia maligna que más se diagnóstica en mujeres. Se estima que una de cada 9 a 12 mujeres con factores de riesgo padecerá la enfermedad a lo largo de su vida en los países del mundo occidental. Objetivo: Profundizar acerca de los factores de riesgo asociados al cáncer de mama. Métodos: Se realizó una revisión bibliográfica temática, observacional y retrospectiva de 25 artículos en el período comprendido desde septiembre 2018 a enero 2019. Se accedió a las bases de datos de Scielo. La búsqueda se hizo en artículos nacionales e internacionales, con textos completos, estos se sometieron a una lectura crítica utilizando métodos teóricos (análisis histórico-lógico y análisis-síntesis) y empíricos (análisis documental). Conclusiones: Se evidenció que el sexo femenino, la edad, el sobrepeso, la obesidad, el tabaquismo, el alcoholismo, el color de la piel, los antecedentes heredofamiliares de cáncer, la edad de la menarquía, la edad de la menopausia, los antecedentes de enfermedades benignas de la mama, el uso de tratamiento de reemplazo hormonal, la cantidad de hijos, el tiempo de lactancia materna y la actividad física, entre otros, constituyen factores de riesgo predisponentes al cáncer de mama, de ahí la importancia del reconocimiento de estos para la prevención y el diagnóstico precoz.

ABSTRACT Introduction: Breast cancer is the most frequent malignant tumor among women worldwide. Considering the two sexes, it is the second in frequency, after lung cancer. In Cuba, it is still the malignant neoplasm that is most diagnosed in women. It is estimated that one in 9 to 12 women with risk factors will suffer the disease throughout their lives in countries of the western world. Objective: To elaborate on the risk factors associated with breast cancer. Methods: A thematic, observational and retrospective bibliographic review of 25 articles was carried out in the period from September 2018 to January 2019. We accessed the Scielo databases. The search was performed in national and international articles, with full texts, which were subjected to critical reading using theoretical (historical-logical analysis and analysis-synthesis) and empirical (documentary analysis) methods. Conclusions: Evidenced showed that the female sex, age, overweight, obesity, smoking, alcoholism, skin color, hereditary family history of cancer, age of menarche, age of menopause, history of benign breast diseases, the use of hormone replacement treatment, the number of children, the time of breastfeeding, physical activity, among others, are risk factors predisposing to breast cancer; hence the importance of recognizing them for prevention and early diagnosis.

Pubertad en pacientes con hiperplasia adrenal congénita por déficit de 21hidroxilasa y asignación femenina / Puberty in patients with congenital adrenal hyperplasia due to a 21-hydroxylase deficit and female assignment

RESUMEN Introducción: En la hiperplasia adrenal congénita el aumento de los niveles de andrógenos suprarrenales en las pacientes no tratadas o mal controladas, puede alterar el inicio y/o la progresión puberal (progresión puberal/progresiones puberales?). Objetivos: Describir las características puberales de pacientes con hiperplasia adrenal congénita asignadas como femeninas e identificar si existe asociación entre elementos relacionados con la enfermedad y el inicio y progresión puberales. Métodos: Se incluyeron todas las pacientes con diagnóstico de hiperplasia adrenal congénita asignadas como femeninas, que fueron atendidas en el INEN de enero 2000 a mayo 2019. Resultados: Fueron estudiadas 47 pacientes, con una media de edad de 14,76 ± 7,04 años. Se comprobó un predominio de las formas clínicas clásicas en 25 pacientes (53,19 por ciento), de ellas 11 (23,40 por ciento) fueron formas virilizantes simples, 14 (29,78 por ciento) perdedoras de sal y 22 (46,80 por ciento) formas no clásicas. El inicio del vello pubiano fue a una edad promedio de 7,78 ± 3,2 años. El comienzo de la telarquia resultó en una media de 10,09 ± 2,4 años y la menarquia a los 12,2 ± 2,3 años como promedio. De las 29 pacientes que ya habían menstruado 16 (55,2 por ciento) presentaban irregularidades menstruales. El tiempo entre el inicio puberal y la menarquia fue de 3,4 años en las formas no clásicas, 5,6 años en las perdedoras de sal y 7,0 años en las virilizantes simples. La edad al diagnóstico, la edad de inicio del tratamiento y la dosis de esteroides empleada se relacionaron con algunos aspectos puberales. Conclusiones: El diagnóstico oportuno y el ajuste cuidadoso del esquema esteroideo, constituyen pilares importantes en el inicio y progresión puberales, y en la consecución de ciclos ovulatorios regulares que aseguren desde la adolescencia, un inicio y desarrollo puberales normales y en edades reproductivas, la optimización de la fertilidad(AU)

ABSTRACT Introduction: In the congenital adrenal hyperplasia, the increased levels of adrenal androgens in patients untreated or poorly controlled can alter the start and/or pubertal progression (pubertal progression/pubertal progressions). Objectives: To describe the pubertal characteristics of patients with congenital adrenal hyperplasia assigned as females and to identify whether there is an association between elements related to the disease and the pubertal onset and progression. Methods: There were included all patients diagnosed with congenital adrenal hyperplasia assigned as females that were attended at the National Institute of Endocrinology from January 2000 to May 2019. Results: 47 patients were studied, with an average age of 14.76 ± 7.04 years. It was found a predominance of classic clinical forms in 25 patients (53.19 percent, of which 11 (23.40 percent) had simple virilization forms, 14 (29.78 percent) were salt-losers and 22 (46.80 percent) had non-classical forms. The onset of the pubic hair was at an average age of 7.78 ± 3.2 years. The beginning of the thelarche resulted in an average of 10.09 ± 2.4 years and menarche at the 12.2 ± 2.3 years on average. Of the 29 patients who had menstruated, 16 (55.2 percent) presented menstrual irregularities. The time between the puberty onset and menarche was 3.4 years in the non-classical forms, 5.6 years in the salt-losers, and 7.0 years in the simple virilizations. The age at initial diagnosis treatment and the dose of steroids used were related to some pubertal aspects. Conclusions: Early diagnosis and careful adjustment of the steroid scheme are important pillars in the pubertal onset and progression, the achievement of regular ovulatory cycles, and with it, in the optimization of fertility(AU)

Association of body composition and age at menarche in girls and adolescents in the Brazilian Legal Amazon / Associação da composição corporal e idade da menarca em meninas e adolescentes na Amazônia Brasileira

Abstract Objective: To analyze the association between age at menarche and variables of body composition in girls from the Northern region of Brazil, the Brazilian Legal Amazon. Method: The sample was composed of 926 school girls, aged between 8 and 18 years, divided into two groups, those who had (G1; n = 727; 72.5%) and had not undergone menarche (G2; n = 199; 21.5%), from public and private schools, using the stratified random proportional sampling technique. Weight, fat weight, muscle weight, and body mass index were measured using bioimpedance analysis. Body height was measured using a stadiometer. Age at menarche was obtained using the conventional method. For the evaluation of sexual maturation, self-assessment was performed according to criteria described by Tanner. Results: The highest cumulative distribution of menarche was found at age 11, and presented significant differences between G1 and G2 at ages 11 and 12 years in all variables of body composition, except body mass index Z-score. Fat and muscle mass were associated with age at menarche. Conclusion: The present results support the notion of menarche anticipation in girls from Brazilian Amazon and its association with body composition. Further studies are needed to investigate the influence of other possible factors that may interfere with the time of growth spurt, thus determining the timing of puberty in these girls in comparison to other regions of Brazil.

Resumo Objetivo Analisar a associação entre idade da menarca e variáveis da composição corporal em meninas na região norte do Brasil, a Amazônia brasileira. Método A amostra foi composta por 926 meninas em idade escolar, entre 8 e 18 anos, divididas em dois grupos, com presença de menarca (G1), n = 727 (72,5%) e ausência (G2) n = 199 (21,5%), provenientes de escolas públicas e privadas, com a técnica de amostragem aleatória estratificada proporcional. Peso, massa de gordura, massa muscular e índice de massa corporal foram medidos através da análise de bioimpedância. A altura foi medida com um estadiômetro. A idade da menarca foi obtida pelo método status quo. Para a avaliação da maturação sexual, a autoavaliação foi realizada de acordo com os critérios descritos por Tanner. Resultados A maior distribuição cumulativa da menarca foi encontrada aos 11 anos e apresentou diferenças significativas entre a presença e ausência de menarca aos 11 e 12 anos em todas as variáveis de composição corporal, exceto o escore-z do índice de massa corporal. Massa de gordura e massa muscular foram associadas com a idade da menarca. Conclusão Os resultados apresentados corroboram a antecipação da menarca em meninas da Amazônia brasileira e sua associação com a composição corporal. Mais estudos são necessários para investigar a influência de outros possíveis fatores que podem interferir na época do estirão de crescimento e determinar, assim, a ocorrência da puberdade em meninas amazônicas em comparação com as de outras regiões do Brasil.

Early menarche and its association with anthropometric and body composition variables in young university students / Menarquia precoz y su asociación con parámetros antropométricos y de composición corporal en jóvenes universitarias

OBJECTIVE: Evaluate the association between early menarche and anthropometric/body composition variables in young female university students. METHODS: Cross-sectional study involving female university students at a public university in northeastern Brazil. Anthropometric and body composition data were collected, along with a self-report of age at menarche. The conceptual model considered demographic, socioeconomic and lifestyle variables as well as the perception of weight in childhood and at menarche. RESULTS: Among the 162 students analyzed, 62.3% were less than 20 years of age. The frequency of underweight and overweight was 8.6% and 22.3%, respectively. The frequency of above-average body fat and obesity was 32.1% and 14.8%, respectively. Early menarche was reported in 35.2%. The frequency of self-reported excess weight in childhood and at menarche was 31.3% and 25.9%, respectively. A statistically significant association was found between early menarche and height < 1st tertile (< 1.62 m). A tendency toward an association was found between early menarche and both weight, circumference in the risk range and the perception of excess weight in childhood and at menarche. CONCLUSION: Current excess weight was more associated with excess weight in childhood and at menarche than the occurrence of early menarche.

OBJETIVO: Evaluar asociación entre menarquia precoz, parámetros antropométricos y de composición corporal en jóvenes universitarias. MÉTODOS: Estudio transversal en 162 jóvenes universitarias del Nordeste brasileño. Se recogieron datos antropométricos, de composición corporal y relato sobre la edad de la menarquia. Se consideraron, además, variables demográficas, socioeconómicas, estilo de vida e histórico del peso. RESULTADOS: De las 162 jóvenes el 62,3% tenía menos de 20 años de edad. Un 8,6% y 22,3% presentaron bajo peso, y exceso de peso respectivamente. La frecuencia de grasa corporal y obesidad por encima de la media fue de 32,1% y 14,8%, respectivamente. La menarquia temprana fue reportada en el 35,2% de los casos. El 31,3% y 25,9% repostaron tener exceso de peso en la infancia y en la menarquia respectivamente. Se verificó asociación estadísticamente significativa entre menarquia precoz y talla <1 tercil (<1,62cm). Además de una tendencia de asociación entre menarquia precoz, circunferencia de la cintura y exceso de peso, tanto en la infancia como en la edad de menarquia. CONCLUSIÓN: el exceso de peso actual está, mas asociado con el exceso de peso en la infancia y la edad de la menarquia que con la menarquia precoz.

Height and sexual maturation in girls with juvenile idiopathic arthritis / Estatura e maturação sexual em meninas com artrite idiopática juvenil

Abstract Objective To evaluate height, sexual maturation, and the difference between final and expected height in girls with juvenile idiopathic arthritis and no glucocorticoid treatment for at least six months, as compared to a group of healthy girls. Methods This cross-sectional study involved 44 girls with juvenile idiopathic arthritis, diagnosed according to the International League of Associations for Rheumatology criteria, and 59 healthy controls aged between 8 and 18 (incomplete) years with no comorbid chronic diseases. Demographic data were collected from all participants, and disease and treatment variables were compiled for the patient group. Anthropometric measurements were converted into Z-scores based on World Health Organization standards. Sexual maturation was classified according to Tanner stages. Results Body mass index and height Z-scores were lower in girls with juvenile idiopathic arthritis as compared to control participants. These values differed significantly in Tanner stage II. Three (6.8%) girls with juvenile idiopathic arthritis had height-for-age Z-scores <−2 (short stature). Girls with polyarticular juvenile idiopathic arthritis and higher cumulative glucocorticoid doses were significantly more likely to present with short stature. The percentage of prepubertal girls in the juvenile idiopathic arthritis group was significantly higher than that observed in the control group, (p = 0.012). Age of menarche, adult height, and the difference between actual and expected height did not differ between groups. Conclusion These findings suggest that even six months after the suspension of glucocorticoid treatment, children with polyarticular/systemic juvenile idiopathic arthritis subtypes are still susceptible to low height and delayed puberty.

Resumo Objetivo Avaliar a estatura, maturação sexual e a diferença entre a estatura final e a esperada em meninas com artrite idiopática juvenil (AIJ) sem tratamento com glicocorticoides por pelo menos seis meses, em comparação com um grupo de meninas saudáveis. Métodos Este estudo transversal avaliou 44 meninas com artrite idiopática juvenil, diagnosticadas de acordo com os critérios da International League of Associations for Rheumatology e 59 controles saudáveis, entre oito e 18 anos (incompletos) sem comorbidades por doenças crônicas. Os dados demográficos foram coletados de todos os participantes e as variáveis de doença e tratamento foram compiladas para o grupo de pacientes. As medidas antropométricas foram convertidas em escores-z com base nos padrões da Organização Mundial da Saúde. A maturação sexual foi classificada de acordo com os estágios de Tanner. Resultados Índice de massa corporal e escores-z de estatura foram menores em meninas com artrite idiopática juvenil em comparação com os participantes-controle. Esses valores diferiram significativamente no estágio II de Tanner. Três (6,8%) meninas com artrite idiopática juvenil tinham escores-z de estatura para idade < -2 (baixa estatura). Meninas com artrite idiopática juvenil poliarticular e doses cumulativas de glicocorticoides foram significativamente mais propensas a apresentar baixa estatura. A porcentagem de meninas pré-púberes no grupo artrite idiopática juvenil foi significativamente maior do que a observada no grupo controle (p = 0,012). A idade da menarca, a estatura adulta e a diferença entre a estatura real e a esperada não diferiram entre os grupos. Conclusão Esses achados sugerem que, mesmo após seis meses da suspensão do tratamento com glicocorticoides, as crianças com os subtipos poliarticular/sistêmico de AIJ ainda são suscetíveis a baixa estatura e atraso na puberdade.

Aspectos reprodutivos de mulheres celíacas no Brasil / Reproductive aspects in brazilian celiac women

ABSTRACT BACKGROUND: Celiac disease (CD) is a chronic enteropathy in response to ingestion of gluten. CD was associated with gynecological disorders. OBJECTIVE: In this retrospective study, we aimed to investigate the age of menarche, age of menopause, number of pregnancies and abortions in Brazilian celiac patients. METHODS: We studied 214 women diagnosed with CD and as control group 286 women were investigated. RESULTS: Regarding the mean age of menarche, a significant difference was found (12.6±1.40 in CD and 12.8±1.22 years in healthy group; P=0.04). Regarding abortions, in CD women 38/214 (17.8%) and 28/286 (9.8%) in the control group reported abortion (P=0.0092, OR:1.98; CI95%=1.1- 3.3). There was no significant difference in the mean age of menopause nor number of pregnancies per woman. CONCLUSION: In this study, we found that celiac women had a higher mean age of menarche and higher risk of spontaneous abortions.

RESUMO CONTEXTO: A doença celíaca é uma enteropatia crônica em resposta à ingestão de glúten e já foi associada a distúrbios ginecológicos. OBJETIVO: Neste estudo retrospectivo, visamos investigar a idade da menarca, idade da menopausa, número de gestações e abortos em pacientes celíacas brasileiras. MÉTODOS: Foram estudadas 214 mulheres com diagnóstico de doença celíaca e no grupo controle, 286 mulheres foram investigadas. RESULTADOS: Em relação à média de idade da menarca foi encontrada diferença significativa (12,6±1,40 na doença celíaca e 12,8±1,22 anos no grupo controle; P=0,04). Em relação aos abortos, nas mulheres com doença celíaca 38/214 (17,8%) relataram ter tido pelo menos um abortamento espontâneo, enquanto que 28/286 (9,8%) no grupo controle relataram aborto (P=0,0092, OR: 1,98; IC95% = 1,1-3,3). Não houve diferença significativa na idade média da menopausa nem no número de gestações por mulher. CONCLUSÃO: Neste estudo, constatamos que as mulheres celíacas apresentaram maior idade média de menarca e maior risco de abortos espontâneos.

The influence of maturational and morphological status pre- and post-menarche on the 100-m freestyle swimming performance of competitive teenagers

Abstract Aim: This study investigated whether the difference anthropometric of swimmers pre- and post-menarche influence the motor performance of a 100-m freestyle swimming test. Methods: Twenty-five female swimmers participated in this study, nine swimmers have not had menarche (age 11.7 ± 0.63), and sixteen swimmers already have had it (age 15.17 ± 1.36). Body composition (skinfold thickness), anthropometrical parameters (height and weight), and biological age (Tanner self-assessment) were measured. A univariate and multivariate linear regression analysis was run to assess which personal or anthropometric variable predicts the motor performance (time trial) on a 100-m freestyle swimming test in pre- and post-menarche participants. As well, it was performed a Pearson's correlation test between the maturational status on Tanner self-assessment and the motor performance. Results: Post-menarche swimmers demonstrated better motor performance than pre-menarche swimmers. Anthropometric characteristics did not predict the motor performance of pre-menarche swimmers. Age, height, and weight predicted 47.8% of the motor performance of post-menarche swimmers. The Tanner classification demonstrated a strong negative correlation with swimming performance. Conclusion: Anthropometric characteristics only impacted the motor performance of post-menarche swimmers.

Menarca y estado nutricional en niñas del periurbano de la ciudad de La Plata, Argentina / Menarche and nutritional status in peri-urban girls of La Plata city, Argentina

La menarca constituye un hito madurativo importante. A escala mundial ocurre, en promedio, a los 12,5 años y está sujeta a factores genéticos y/o ambientales. El objetivo fue analizar, en niñas residentes en la periferia urbana de La Plata: a) la edad mediana de menarca y b) si el estado nutricional y la distribución adiposa influyen en la edad de ocurrencia de menarca. Se evaluaron, durante los ciclos 2014-2017, en 657 niñas de 10-14 años: presencia(P)/ausencia(A) de menarca, peso, talla y pliegues subcutáneos tricipital y subescapular. Se determinaron: edad mediana de menarca (EM) según método status quo y regresión logística; estado nutricional -desnutrición, exceso ponderal y normonutrición- empleando como referencia y puntos de corte a la OMS; y distribución de adiposidad según índice subescapular/tricipital, considerando valores >1 indicativos de adiposidad centralizada. Se calcularon en general y por estado nutricional la EM y las prevalencias de ocurrencia comparándose mediante Chi2. La menarca estuvo presente en el 44,10% de las niñas con EM de 12,13 años. Alrededor del 54% de las niñas se mantuvo dentro de los límites normales (P: 41,20%; EM: 12,28 años) y el 45,70% estaban desnutridas; de estas 4,90% mostraron desnutrición debido a la baja estatura (P: 25,00%; MS: 13,40 años) y 40,80% tenían exceso de peso (P: 50,40%; MS: 11,78 años). El 32,72% de las niñas tenían adiposidad centralizada (P: 59,10%; EM: 11,79 años). Los resultados permiten concluir que el estado nutricional influye en la edad mediana de ocurrencia de la menarca, la cual es mayor en las niñas desnutridas y menor en las niñas con exceso ponderal. La disposición centralizada de la adiposidad favorece la presencia de menarca(AU)

Menarche is an important maturation milestone. It normally occurs at an average age of 12.5 years and is influenced by genetic and/or environmental factors. The aim of this study was to analyze in girls residing at suburbs of La Plata city a) the median age of menarche; b) if nutritional status and fat distribution have any influence in the age of menarche. During years 2014 to 2017, 657 girls aged between 10 and 14 years(y) were surveyed, determining: presence(P)/absence(A) of menarche, weight, height, and tricipital and subscapular skinfolds. It was measured: median age of menarche (MA) according to the status quo method and logistic regression; nutritional status -undernutrition, excess weight, and normonutrition- using WHO as a reference and their cut-off points; and the distribution of adiposity through the use of subscapular/tricipital index, considering values >1 an indicative of centralized adiposity. The median age of menarche was calculated both in the general sample and by nutritional status; general and age-prevalence of menarche were compared by Chi2. Menarche was present in 44.10% of the girls with MS of 12.13 years. About 54% of the population stayed within normal limits (P: 41.20%; MS: 12.28 years) and 45.70% were malnourished; of these 4.90% showed malnutrition due to short stature (P: 25.00 %; MS: 13.40 years) and 40.80% had weight excess (P: 50.40%; MS: 11.78 years). 32.72% of the girls had centralized adiposity (P: 59.10%; MS: 11.79 years). These results allow us to conclude that nutritional status influences the median age of menarche: it is higher in undernourished girls and lower in those with weight excess. Centralized disposition of adiposity promotes the presence of menarche(AU)

ERICA: age at menarche and its association with nutritional status / ERICA: idade da menarca e sua associação com o estado nutricional

Abstract Objective: To estimate the mean age at menarche and its association with nutritional status in Brazilian adolescents. Methods: The study sample included female adolescents aged 12-17 who participated in a multicenter, school-based, country-wide, cross-sectional study entitled The Study of Cardiovascular Risk in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes [ERICA]). Mean and median ages at menarche in Brazil were estimated. The association of age at menarche with sociodemographic data and nutritional status were described as means and their respective 95% confidence intervals. Survival analysis was used to assess the age at menarche according to nutritional status categories and the log-rank test was used to compare the medians. Bivariate and multivariate analyses were performed using Cox regression to verify the association between menarche and other variables. Results: A total of 73,624 students were evaluated, comprising 40,803 girls, of whom 37,390 reported menarche at a mean age of 11.71 years and a median of 12.41 years. Median age at menarche was lower in overweight and obese girls (p < 0.001). The multivariate analysis showed that excess weight (HR = 1.28; 95% CI 1.21-1.36; p < 0.001) and studying in a private school (HR = 1.06; 95% CI 1.02-1.10; p = 0.003) were associated with menarche. Conclusions: This is a pioneering study in Brazil with national and regional representativeness to estimate the mean and the median age of occurrence of menarche. Adolescents with excess weight had an earlier menarche than their peers, even after adjustment for confounding factors.

Resumo Objetivo: Estimar a média de idade de ocorrência da menarca e sua associação com o estado nutricional em adolescentes brasileiras. Métodos: Foram avaliados dados de meninas com 12 a 17 anos a partir de um estudo seccional de base escolar, com representatividade nacional e macrorregional, o ERICA (Estudo de Riscos Cardiovasculares em Adolescentes). Foram estimadas média e mediana de idade de ocorrência da menarca no Brasil, pelo método recordatório. A associação da idade da menarca com dados sociodemográficos e estado nutricional foi descrita como médias e seus respectivos IC95%. Análise de sobrevida foi utilizada para explorar a idade da menarca segundo categorias de estado nutricional e teste logrank foi utilizado para comparação das medianas. Análises bivariada e multivariada foram realizadas por meio da regressão de Cox para verificar a associação entre menarca e demais variáveis. Resultados: Foram avaliados 73.624 estudantes, 40.803 meninas, das quais 37.390 referiram ter apresentado menarca, sendo a média da idade de ocorrência de 11,71 anos e a mediana de 12,41 anos. As medianas da idade de ocorrência da menarca foram menores naquelas com sobrepeso e obesidade (p < 0,001). A análise multivariada evidenciou que excesso de peso (HR = 1,28, IC95% 1,21-1,36, p < 0,001) e estudar em escola privada (HR = 1,06, IC95% 1,02-1,10, p = 0,003) estão associados à menarca. Conclusões: Este foi o primeiro estudo brasileiro com representatividade nacional a estimar a média de idade de ocorrência da menarca. As adolescentes com excesso de peso apresentaram menarca em idade inferior às demais, mesmo após ajuste.Full English text available from: www.revespcardiol.org/en
