Yet, as recently described by the World Health Organization (WHO), increased recognition of the importance of adolescent health rarely transforms into action. One challenge is lack of data, particularly on adolescent fertility. Adolescent pregnancy and childbirth are widespread and affect lifetime health and social outcomes of women, men, and families. Other important components of adolescent fertility include abortion, miscarriage, and stillbirth. Access to reliable, consistently-collected data to understand the scope and complexity of adolescent fertility is critical for designing strong research, developing meaningful policies, building effective programs, and evaluating success in these domains. Vital surveillance data can be challenging to obtain in general, and particularly in low- and middle-income countries and other under-resourced settings (including rural and indigenous communities in high-income countries). Definitions also v...

However, studies investigating these associations in low- and middle-income settings are scarce, especially for middle-aged populations. Understanding the validity of SRH in relation to objective health measures in low-income populations could assist in decision making about health policy and strategies, especially in under-resourced settings. Objective Assess the relationship between SRH and physical performance measures in middle-aged and older women in a low-income setting of Brazil. Methods This is a cross-sectional study of 571 middle-aged (40–59 years old) and older (60–80 years old) women living in Parnamirim and Santa Cruz in the Northeast region of Brazil. Participants reported their health status and were allocated to the “SRH good” or “SRH poor” groups. The physi...

Our objective is to establish whether OSA increases adverse maternal and neonatal outcomes. Methods: We performed a retrospective cohort study using the Healthcare Cost and Utilization Project − National Inpatient Sample from the United States. All pregnant patients with a diagnosis of OSA were identified using International Classification of Disease-9 coding from 2006 to 2015. Trends of OSA over time were calculated, baseline characteristics were compared between pregnancies with and without OSA, and multivariate logistic regression analysis was used to estimate the effect of OSA on maternal and neonatal outcomes. Results: Among 7,907,139 births included in our study, 3,115 were to women with OSA, for an overall incidence of 39 per 100,000 births. Rates increased over the 10-year study period, from 10.14 per 100,000 births in 2006 and 78.12 per 100,000 births in 2015 (p<0.05). Women with OSA were more likely to have pregnancies complicated by preeclampsia 2.2 (2.0−2.4), eclampsia 4.1 (2.4−7.0), postpartum hemorrhage 1.4 (1.2−1.7), need of blood transfusion 2.2 (1.9−2.7), disseminated intravascular coagulation, 2.4 (1.0−5.4), and venous thromboembolisms, 2.7 (2.1−3.4). Women with OSA were also more likely to develop cardiovascular and respiratory complications. Neonates born to mothers with OSA were more likely to be premature, 1.3 (1.2−1.5), and have congenital malformations, 2.3 (1.7−3.0). Conclusions: OSA in pregnancy is associated with and increased risk of adverse maternal and neonatal outcomes. Women with OSA may benefit from management in Tertiary care centres and closer follow-up during pregnancy.

We evaluate the association between age at natural menopause (ANM) and physical functioning in a sample of postmenopausal women drawn from the International Mobility in Aging Study (IMIAS). Study Design: Retrospective cohort study of 775 women aged 65-74, from Albania, Brazil, Colombia and Canada, who had experienced natural menopause. Main outcome measures: Gait speed and grip strength were obtained following standardized protocols. The association between self-reported ANM (< 40, 40-44, 45-49, 50-54 and ≥55) and gait speed (m/s) and grip strength (kg) was assessed by linear regression analyses adjusting for several life-course economic and reproductive exposures, height, BMI and smoking. Results: Overall, women with ANM ≥ 55 had higher gait speed than those with ANM 50-54 (β = 0.05; 95%CI: 0.01, 0.10). Women with ANM < 40 had significantly lower grip strength compared with all other groups (β= −2.58; 95%CI: −4.43, −0.74). In region-specific analyses, ANM was associated with grip strength in Albania and Latin America and with gait speed in Albania only. No associations were observed in Canada. Conclusions: ANM is associated with markers of physical functioning. Differences across study sites suggest that women in socially disadvantaged areas may reach menopause with different physiological reserves than those from more advantaged settings, leading to greater losses in muscle strength in postmenopausal years. More work comparing distinct populations is needed to better understand the underlying mechanisms.

Herein, we examine the association of AFB with a summary cardiovascular risk measure (Framingham Risk Score [FRS]). As part of the IMIAS (International Mobility in Aging Study), data were collected in 2012 among 1047 women, aged 65 to 74 years, from Canada, Albania, Colombia, and Brazil. FRSs were calculated to describe cardiovascular risk profiles, and linear regression analyses were performed, adjusting for early life and socioeconomic variables. Women with an AFB of <20 years were compared with women with an AFB of 20 to 24, 25 to 29, and ≥30 years, as well as nulliparous women. We also compared FRS between combinations of AFB and parity categories: nulliparous women, parity 1 to 3 combined with AFB <20 years, parity ≥4 with AFB <20 years, parity 1 to 3 with AFB ≥20 years, and parity ≥4 with AFB ≥20 years. Women with an...

Sabe-se que a FMI é determinante na estabilidade corporal e na locomoção, sendo de extrema importância sua avaliação de forma precisa. Portanto, o objetivo desse estudo foi avaliar a correlação entre a FPM e FMI (flexores e extensores de joelho) em mulheres de meia idade. Trata-se de um estudo observacional analítico, transversal, com 395 mulheres (40 a 65 anos), avaliadas quanto à FPM e FMI (flexores e extensores de joelho). Foi utilizada correlação de Pearson, regressão linear e análise de Bland-Altman para análise dos dados, considerando significância de 5%. A média de idade das mulheres foi de 49,75(±5,8) anos. A média da FPM e FMI (flexão e extensão de joelho) foram, respectivamente: 25,8 (±5,4), 14,7 (±4,9) e 16,5 (±4,5) Kgf. Após análise de regressão linear e análise ...

The aim of this paper is to investigate whether reproductive history is associated with physical function in middle-aged women from Northeast Brazil. Methods: The relationship between poor physical performance (grip strength, gait speed and chair stand), early maternal age at first birth (<18 years old), and multiparity (≥3 children) was evaluated in a community sample of 473 women living in Parnamirim (Northeast Brazil). Linear regression models were used to examine the relationship of interest; in addition, mediation analyses were employed to assess indirect effects of obesity and family income. Results: Women who gave birth at less than 18 years of age took approximately 0.50 s longer to complete the chair stand test compared to women who gave birth at 18 years or older. Moreover, women who gave birth to < 3 children completed the chair stand test 0.42 s faster compared to those who had ≥ 3 children. The relation between reproductive history and physical performance was mediated by BMI. Reproductive history was not associated with performance in gait speed. Conclusions: This study provides evidence that adolescent childbirth and multiparity are related to worse physical performance in middle-aged women from a low income setting. Reproductive history may partially account for earlier physical decline and greater disability in women from lower income settings.

Understanding the health literacy of young pregnant women in low-income settings could support strategies to reduce adverse outcomes in this population. This exploratory study assessed the health literacy of young pregnant adolescents and young adults from a rural area in Northeast Brazil and associated factors such as socioeconomic conditions, adequacy of prenatal care, and social support from family and friends. In this cross-sectional study, 41 pregnant adolescents (13–18 years) and 45 pregnant adults (23–28 years) from the Rio Grande do Norte state, Brazil, were assessed regarding health literacy through the Short Assessment of Health Literacy for Portuguese-Speaking Adults (SAHLPA, score from 0–18, inadequate if <15). Income sufficiency, self-perceived school performance, compliance with recommen...

Methods: Study conducted with 510 women divided into three age groups: 45–54, 55–64 and 65–74 years. Socioeconomic, reproductive and lifestyle variables were self-reported. We defined metabolic syndrome using the National Cholesterol Education Program Adult Treatment Panel III criteria (abdominal obesity, diabetes, reduced high-density lipoprotein, elevated triglycerides, and hypertension). Logistic regression assessed the association between age groups, and metabolic syndrome was adjusted for covariates (socioeconomic variables, age at menarche and at first childbirth, parity, menopausal status, physical activity variables and smoking). Results: Women aged 55–64 years presented higher prevalence of all metabolic syndrome criteria than the other groups, except for abdomi...

This study aimed to analyze associations between late-onset sepsis in very low birth weight infants (<1500 g) and days of parenteral nutrition, days to reach full enteral nutrition, and maternal and nutritional factors. Methods: A cross-sectional study was carried out with very low birth weight infants admitted to a neonatal intensive care unit (NICU) of a reference maternity hospital of high-risk deliveries. Data regarding days of parenteral nutrition, days to reach full enteral nutrition, fasting days, extrauterine growth restriction, and NICU length of stay were extracted from online medical records. Late-onset sepsis was diagnosed (clinical or laboratory) after 48 h of life. Chi-squared, Mann–Whitney tests, and binary logistic regression were applied. Results: A total of 97 preterm ...

It is known that the lower limb strength is determinant in the body stability and locomotion, being extremely important assess it accurately. Therefore, the objective of this study is to evaluate the correlation between grip strength and lower limb strength (knee flexors and extensors) in middle-aged women. It was a cross-sectional study with 395 women (40 to 65 years old) assessed regarding the grip strength and lower limb strength (knee’s flexors and extensors). It was used Pearson’s correlation, linear regression and Bland-Altman analysis for data analysis and it has been taking into consideration a 5% of significance. The average age of women was 49.75 (±5.8) years. The mean of grip strength and knee’s flexor and extensor strength were, respectively: 25.8 kgf (±5.4), 14.7 kgf ...
