“… [49] The equiplots also showed that the birthweight indicators would be worse for mothers aged <19 years; this observation agrees with the literature on the subject. [ 50 , 51 ] Regarding low birthweight prevalence, the youngest mothers were closely followed by those aged 36+ years, which has also been documented before. [52] Both extremes of the reproductive age are considered at risk for adverse birth outcomes, and the prevalence of adverse birth outcomes have kept similar along time.…”

Summary Background National and subnational characterization of birthweight profiles lacks in low- and middle-income countries, yet these are needed for monitoring the progress of national and global nutritional targets. We aimed to describe birthweight indicators at the national and subnational levels in Peru (2012-2019), and by selected correlates. Methods We studied mean birthweight (g), low birthweight (<2,500 g) and small for gestational age (according to international growth curves) prevalences. We analysed the national birth registry and summarized the three birthweight indicators at the national, regional, and province level, also by geographic area (Coast, Highlands, and Amazon). With individual-level data from the mother, we described the birthweight indicators by age, educational level and healthcare provider. Following an ecological approach (province level), we described the birthweight indicators by human development index (HDI), altitude above sea level, proportion of the population living in poverty and proportion of rural population. Findings Mean birthweight was always the lowest in the Highlands (2,954 g in 2019) yet the highest in the Coast (3,516 g in 2019). The same was observed for low birthweight and small for gestational age. In regions with Coast and Highlands, the birthweight indicators worsen from the Coast to the Highlands; the largest absolute difference in mean birthweight between Coast and Highlands in the same region was 367 g. All birthweight indicators were the worst in mothers with none/initial education, while they improved with higher HDI. Interpretation This analysis suggests that interventions are needed at the province level, given the large differences observed between Coast and Highlands even in the same region.

“…In addition to its adverse impacts on physical growth and health status, anemia can also negatively affect cognitive development, school attendance and school performance [ 13 , 15 ], hindering their educational achievement as well as their future labor productivity [ 16 ]. In pregnant adolescents, anemia may raise the risk of maternal and neonatal mortality [ 17 , 18 ], delivery of low birth-weight infants, as well as birth complications [ 19 ]. Therefore, anemia does not only represent a concern for today’s adolescents, but also for the future development of communities and societies [ 20 ].…”

This study assesses the prevalence and correlates of anemia among adolescents living in the war-affected region of Hodeida in Yemen. A secondary objective was to examine the effect of a nutrition education intervention on hemoglobin levels among anemic adolescents. A cross-sectional study was conducted on a random sample of adolescents aged 15–19 years in Hodeida (n = 400). A questionnaire was administered to inquire about demographic, socioeconomic, lifestyle and clinical characteristics. Capillary blood was obtained, anthropometric characteristics were measured and stool samples were collected. As for the secondary objective, anemic adolescents were randomly assigned to an intervention group (nutrition education and iron supplementation) and a control group (iron supplements only). The prevalence of anemia was 37.8%. Female gender, khat chewing, excessive menstruation, and experiencing headaches, fatigue, or dizziness were independent predictors of anemia. In contrast, adolescents who attended private schools, and reported snack consumption or handwashing had a significantly lower risk of anemia. A sample of 116 adolescents participated in the intervention (3 months). Hemoglobin levels were significantly higher in the intervention group compared to the control. Our findings contribute to the identification of high-risk groups that should be targeted by context-specific interventions. The implemented multicomponent intervention may serve as a prototype for larger-scale preventive programs.

“…These factors include: advanced maternal age, educational level, grand multiparity, adolescent pregnancy, primiparity, low socioeconomic status, place of delivery, maternal comorbidity (diabetes mellitus, hypertension, HIV infection, preeclampsia), fetal condition (prematurity, low birthweight, post-term pregnancy, congenital anomalies), Antepartum Hemorrhage (APH), prolonged labor, and lack of antenatal care. 4,7,[12][13][14][15][16][17][18][19][20][21][22] However, these factors may vary across countries and time trends depending on the quality and accessibility of care in the health facility and estimates for stillbirth determinants are impeded by various classification systems because of the unavailability of reliable data.…”

Background Worldwide, 2.6 million stillbirths occur annually and more than three-quarters of them are recorded in South Asia and Sub-Saharan Africa. Thus, the aim of this study was to identify risk factors of stillbirth among women who gave birth in Amhara region referral hospitals found in northwest and northcentral, Ethiopia in 2019. Methods A multi-center institution-based unmatched case-control study was conducted among 456 mothers who gave birth in Amhara region referral hospitals from October 1 to December 30, 2019. Consecutive and simple random sampling was used to select the cases and controls, respectively. A semi-structured, interviewer-administered questionnaire and patient chart reviews were used to collect the data. Epidemiological (Epi) data version 4.4.2.1 and Statistical Package for the Social Sciences (SPSS) version 25.0 were used for data entry and analysis, respectively. Binary logistic regression was employed. An adjusted odds ratio with a 95% confidence interval was used to declare statistically significant variables on the basis of p -value<0.05 in the multivariable binary logistic regression model. Results Alcohol drinking (adjusted odds ratio (AOR)=3.02, 95% confidence interval (CI)=1.24–7.35), antepartum hemorrhage (AOR=5.74, 95% CI=2.67–12.33), premature rupture of membrane (AOR=2.21, 95% CI=1.09–4.44), meconium-stained amniotic fluid (AOR=8.18, 95% CI=4.29–15.60), non-use of partograph for labor follow-up (AOR=3.89, 95% CI=2.12–7.17), induction of labor (AOR=2.12, 95% CI=1.09–4.11), previous history of stillbirth (AOR=2.15, 95% CI=1.08–4.26), and birthweight less than 2,500 grams (AOR=7.36, 95% CI=3.43–15.81) increase the odds of stillbirth. Conclusion Stillbirth was higher among women who drank alcohol during their pregnancy, experienced antepartum hemorrhage, premature rupture of membrane, meconium-stained amniotic fluid, induction of labor, labor not followed by partograph, previous history of stillbirth, and birthweight less than 2,500 grams. As such, education to stop alcohol drinking during pregnancy, monitoring the progress of labor with partograph, and improving the quality of care for mothers and newborns at the time of pregnancy and childbirth will contribute to preventing stillbirth.
