Abstract
We established the 2019 Rio Grande birth cohort to investigate the life course epidemiology of mental health and its intergenerational transmission. In 2019, we systematically identified all hospital births in the city of Rio Grande, located in Southern Brazil. Mothers who delivered a singleton liveborn child were administered a standardized, face-to-face questionnaire. In 2020, we conducted 2 follow-up assessments (WebCOVID-19 1 and 2), a third in 2021-22 (WebCOVID-19-3), and a fourth in 2023-24 (WebPOST-COVID). Across these follow-ups, we collected data on socio-demographic, environmental, and behavioral factors pertaining to both mother and child, as well as maternal mental health. Child mental health and development were specifically evaluated during the fourth follow-up. At baseline, 2,051 mothers were interviewed. Response rates for the online follow-ups were 54.1%, 51.1%, 48.7%, and 34.6%, respectively. In WebCOVID-19-3, the highest prevalence rates for depression (34.7%) and anxiety (33.1%) were observed. This cohort provides novel insights into maternal mental health, child development, and post-coronavirus disease 2019 behaviors, emphasizing culturally specific risk factors. Our findings are based on both published and ongoing studies. Data may be requested upon reasonable request.
Summary
Key Message
The 2019 Rio Grande Birth Cohort is a prospective study that has been following over 2,000 mothers and their children since 2019. It is designed specifically to understand the intergenerational transmission of mental health problems. The cohort's unique design combines detailed face-to-face questionnaires at baseline with remote, web-based follow-ups, and serves as a comprehensive overview of the cohort's methodology, data collection instruments, and study design, demonstrating its potential to generate valuable insights into maternal and child health.

Abstract
OBJECTIVES
Anemia in children under 5 years of age is often overlooked despite its detrimental effects. The public health approach to anemia prevention includes the maternal pre-pregnancy phase. This study investigated the association between pre-pregnancy anemia and the risk of anemia in children under 5 years of age.
METHODS
This cohort study included non-pregnant women from the 2007 Indonesian Family Life Survey (IFLS) and their children under 5 in the 2014 IFLS. The anemia status of mothers and children was determined based on hemoglobin (Hb) levels using Hemocue. Mantel-Haenszel adjusted relative risks (aRRs), including risk stratification by covariates, were used for the final risk assessment.
RESULTS
In total, 637 children in the 2014 IFLS were included. The risk of having a child with anemia was 1.71-fold higher in women with pre-pregnancy anemia than in women without pre-pregnancy anemia (aRR, 1.71; 95% confidence interval [CI], 1.03 to 2.85). After risk stratification based on potential confounding variables, maternal pre-pregnancy anemia remained an independent risk factor for anemia in children who still breastfed at the time of data collection (relative risk [RR], 2.11; 95% CI, 1.16 to 3.86), in children who were given water earlier than 6 months of age (RR, 2.08; 95% CI, 1.20 to 3.61), in children of mothers with a normal or underweight pre-pregnancy body mass index (RR, 1.94; 95% CI, 1.20 to 3.14), and in children of mothers without current anemia (RR, 2.20; 95% CI, 1.21 to 3.99).
CONCLUSIONS
Pre-pregnancy anemia increased the risk of childhood anemia. A public health approach emphasizing pre-conception maternal health would enable better maternal and child morbidity risk prevention.
Summary
Key Message
Pre-pregnancy anemia increased the risk of childhood anemia by 1.7 times compared to without pre-pregnancy anemia, and increased when the child was still breastfed, given water before 6 months of age, and the mother had a normal or underweight pre-pregnancy BMI, regardless of the mother’s current no anemia status.

Abstract
OBJECTIVES
Since many Millennium Development Goals (MDGs) were not achieved, countries including Iran—despite achieving some of the MDGs—need regular planning to achieve the Sustainable Development Goals (SDGs) by 2030. This article examines maternal and child health indicators in the early years of the SDGs in Iran relative to several other countries.
METHODS
This study was carried out through a secondary analysis of maternal and child health indicators in Iran. The results were compared with data from other countries divided into three groups: countries with upper-middle income levels, countries in the Eastern Mediterranean region, and the countries covered by the Outlook Document 1,404 (a regional classification). Then, the relationship between these indicators and the Human Development Index was investigated.
RESULTS
Iran has attained better results than other countries with respect to maternal mortality, family planning, skilled birth attendance, under-5 deaths, incidence of hepatitis B, diphtheria-tetanus-pertussis vaccination coverage, and antenatal care. In contrast, Iran performed worse than other countries with respect to under-5 wasting, under-5 stunting, and care-seeking behavior for children.
CONCLUSIONS
Overall, among the 11 indicators surveyed, Iran has attained better-than-average results and seems to be improving. We recommend that Iran continue interventions in the field of maternal and child health.
