Low birth weight is the leading cause of infant and child mortality and contributes to several poor health outcomes. Proper knowledge of risk factors of low birth weight is important for identifying those mothers at risk and thereby for planning and taking appropriate actions. The cross sectional study was designed to investigate the prevalence and possible determents for low birth weight neonate’s delivered at District Head Quarter hospital of District Pakpattan. The overall prevalence of LBW was 8.2%. LBW was significantly associated with mother's gestational age, previous history of low birth weight, poor or no intake of nutrient dense diet during pregnancy, < 4 prenatal care visits and no education. Preterm birth (AOR = 2(1.4-10.4), history of any pregnancy complication (AOR = 3(0.3-7.09) and intake of additional diet (AOR=5(1.9-18.0) were predictors of low birth weight. Preterm birth, poor and no intake of nutrient dense diet, history of low birth weight were possible predictors of low birth weight. Improving maternal socio-demographic could mimic the low birth weight and its associated complications.
