Determinants of Neonatal Mortality in Nepal, 2011- 2016: A Comparative Analysis

Neonatal mortality refers to the risk of death within the first month of life. This study investigates the key factors influencing neonatal mortality in Nepal between 2011 and 2016, focusing on changes over this period.

Data for this research were sourced from the Nepal Demographic and Health Survey (NDHS) for the years 2011 and 2016. Neonatal mortality was the primary outcome variable. Key determinants examined included community-level factors (residence), socio-economic factors (maternal and paternal education, wealth index), maternal characteristics (age, pregnancy duration, antenatal care visits), infant characteristics (sex, birth order, birth interval, birth weight), delivery factors (assistance and location of delivery), and post-delivery factors (breastfeeding status, postnatal check-ups).

Statistical analysis utilized the Chi-squared test to identify significant relationships between determinants and outcomes, alongside a full logistic model based on treatment contrasts. Findings indicated that in 2011, the significant factors included pregnancy duration, postnatal checks, antenatal visits, and having twins. By 2016, important determinants shifted to the mother's age, breastfeeding status, pregnancy duration, postnatal checks, and antenatal visits.

The study highlights that pregnancy duration, postnatal check-ups, and antenatal visits consistently influenced neonatal mortality across both surveys. Given the rarity of studies addressing program impacts on neonatal mortality, this research suggests conducting panel studies to better understand the slow decline of neonatal mortality in Nepal.
