<![CDATA[Maternal nutrition during pregnancy plays a critical role in determining neonatal birth weight, particularly in low-income communities. This cross-sectional study examined the association between maternal nutritional status and infant birth weight among 80 postpartum mothers in Deli Serdang Regency, North Sumatra. Maternal nutrition was assessed using body mass index, upper arm circumference, energy and protein intake, and hemoglobin levels, while birth weight was obtained from medical records. Multivariate regression analysis controlling for maternal and socioeconomic factors showed that low upper arm circumference, inadequate energy and protein intake, and maternal anemia were significant independent predictors of low birth weight. The findings highlight the importance of strengthening community-based maternal nutrition interventions to reduce low birth weight in economically disadvantaged settings]]>
