The influence of nutritional status, the home environment, and schooling on behavioral outcomes of hyperactivity and inattention among grade-school children in rural Nepal
Attention-deficit/hyperactivity disorder (ADHD) in children is characterized by frequent inattention and/or hyperactivity that can affect child development, including learning, social adaptation, and mental health. Despite the impact of these behaviors, data on the prevalence and risk factors of child behavioral and neurodevelopmental disorders in low- and middle-income countries are limited. This paper aims to identify maternal, child and enviro…
Covid-19 vaccine coverage among adults in Sarlahi District of Nepal in 2022
Nepal launched its COVID-19 vaccination campaign in January 2021 through the COVID-19 Vaccines Global Access (COVAX) facility. Vaccine coverage, especially in low- and middle-income countries (LMICs), is measured using administrative-level data; however, this source is often subject to biases and limitations. We conducted a household survey in rural Sarlahi District, Nepal, to estimate COVID-19 vaccine coverage and assess associations with partic…
Impact of topical applications of sunflower seed oil on neonatal mortality and morbidity in southern Nepal
INTRODUCTION: Hospital-based studies have demonstrated topical applications of sunflower seed oil (SSO) to skin of preterm infants can reduce nosocomial infections and improve survival. In South Asia, replacing traditional mustard with SSO might have similar benefits. METHODS: 340 communities in Sarlahi, Nepal were randomised to use mustard oil (MO) or SSO for community practice of daily newborn massage. Women were provided oil in late pregnancy …

Validation of maternal reports for low birthweight and preterm birth indicators in rural Nepal
BACKGROUND: Tracking progress towards global newborn health targets depends largely on maternal reported data collected through large, nationally representative surveys. We evaluated the validity, across a range of recall period lengths (1 to 24 months post-delivery), of maternal report of birthweight, birth size and length of pregnancy. METHODS: We compared maternal reports to reference standards of birthweights measured within 72 hours of deliv…
Why some mothers overestimate birth size and length of pregnancy in rural Nepal
BACKGROUND: Quantitative validation studies alone may not be able to distinguish between instances when participants did not accurately report an event vs when participants did not understand a question. We used an explanatory qualitative study design to acquire an in-depth understanding of why some mothers in rural Nepal overestimate birth size of their newborn and their length of pregnancy. METHODS: We conducted two focus group discussions (FGD…

The post‐partum mid‐upper arm circumference of adolescents is reduced by pregnancy in rural Nepal
The purpose of this study was to examine whether changes in the mid‐upper arm circumference (MUAC) in pregnancy and early post‐partum varied by maternal age. The MUAC of 3359 nulliparous pregnant women ≤25 years of age in rural Nepal was measured in early pregnancy and at 3 months post‐delivery of a live‐born infant. Regression was used to model the change in MUAC and prevalence of MUAC < 20 cm by maternal age, adjusted for confounders. A total o…
Preterm delivery but not intrauterine growth retardation is associated with young maternal age among primiparae in rural Nepal
Pregnancy during adolescence is associated with adverse birth outcomes, including preterm delivery and low birthweight. The nutrient availability to the fetus may be limited if the mother is still growing. This research aims to study the effects of pregnancy during adolescence in a nutritionally poor environment in rural Nepal. This study utilized data from a randomized controlled trial of micronutrient supplementation during pregnancy in south-e…
Risk of flood-related mortality in Nepal
In July 1993, severe flooding devastated Sarlahi district in Nepal. The next month, a follow-up study of a large population cohort was undertaken. The study is unique in that a prospective research database was used to verify residency prior to the flood and to confirm vital status afterwards. It evaluated 41,501 children aged between two and nine years and adults aged 15-70 in 7,252 households. Flood-related fatality rates were 13.3 per 1,000 fo…
