Maternal and socio-demographic determinants of low birth weight (LBW): A community-based study in a rural block of Assam

Background and Rationale: Low birth weight (LBW) leads to high neonatal and infant deaths. There is also high prevalence of childhood morbidities and mortalities that are consequences of LBW. Objectives: To find out the prevalence of LBW babies among the study population and to find out the effect of certain maternal and socio-demographic characteristics on birth weight. Materials and Methods: This cross-sectional study was carried out in a rural block of Assam. Cluster sampling was done to choose 30 villages and 15 infants were selected randomly from each village to get a sample size of 450. Results: Prevalence of LBW was found to be 21.8%. Percentage of LBW babies was more among the teenage mothers (36%) and primipara mothers (27%). Maternal anemia [ odds ratio (OR) 1.93; confidence interval (CI) 1.3-2.9], short interpregnancy interval (OR 3.93; CI 2.16-7.13), and teenage pregnancy (OR 3.93; CI 2.16-6.45) were found to be the independent risk factors associated with LBW of the babies. Discussion: The study findings indicated the high prevalence of LBW babies in rural areas of Assam and illiterate teenage mothers, grand multipara, anemic mothers, and short interpregnancy intervals were the important risk factors for LBW.
