The risk of low birth weight and associated factors in West Bengal, India: a community based cross-sectional study

Abstract

Abstract Background Low birth weight (LBW) is a challenging multifaceted public health problem as it associated with infant mortality. Present study was undertaken to assess magnitude and risk factors associated with LBW in West Bengal, India. A community-based cross-sectional study was carried out among 2611 birth episodes in different districts of West Bengal using multi-stage stratified cluster sampling, followed by systematic random sampling methodology. Participants were interviewed by semi-structured questionnaires containing socio-demographic, pregnancy, and mothers’ health-related variables. Results This study revealed that 21.49% infants were born LBW. The risk of LBW was higher among women those age < 20 years and BMI < 18.5 kg/m2. The odd of giving LBW baby were higher among women having weight < 45 kg and height < 150 cm. Anemic (AOR 3.33) and hypertensive (AOR 1.69) women were more likely to give LBW baby. Preterm delivery (AOR 1.93) and history of chronic illness (AOR 2.09) were the determinants of LBW. The odd of LBW was higher among women who never followed ANC visit (AOR 1.35). The likelihood of giving LBW baby was higher among women who did not consume iron folic acid tablet and additional diet during pregnancy. More LBWs were observed among women who were from low socioeconomic family, rural residence, and illiterate. Conclusions This study provided scientific recommendations during preconception period which will help to target women who may potentially benefit from lifestyle and dietary interventions. To reduce LBW community specific strategies such as improving awareness of the community and utilization of existing maternal health services is essential.
