Low birth weight (LBW), defined as a weight of less than 2.5 kg at birth, is a significant public health concern in India, contributing to higher infant mortality rates and long-term health issues for affected children. A recent analysis of the National Family Health Survey conducted by researchers from Duke and Harvard University’s highlights that nearly half of India’s low birth weight cases can be traced back to just four states: Uttar Pradesh, Bihar, Maharashtra, and West Bengal. Although India has made progress in reducing the overall prevalence of LBW—from 26% in 1993 to 18% in 2021—the disparity among states is notable, with some regions still experiencing alarmingly high rates.
The study indicates that a substantial portion of low birth weight cases is linked to inadequate healthcare infrastructure. It was found that babies who were not weighed at birth show significantly higher rates of low birth weight, suggesting that those births likely occurred outside of health facilities where proper medical care is available. Moreover, a strong correlation exists between low socioeconomic status and LBW, as families facing economic difficulties often struggle to access necessary healthcare services and proper maternal nutrition.
Educational disparities also emerge as a critical factor contributing to low birth weight. Data suggests that mothers with little or no formal education are significantly more likely to give birth to underweight infants. This emphasizes the necessity of education, as it impacts women’s understanding of health and nutrition during pregnancy. Furthermore, researchers noted that the prevalence of low birth weight among newborns showed a decline over the decades, but approximately 42 lakh babies were born with low weight in India in a single year, largely from the already mentioned four states.
The findings of the analysis draw attention to the health implications associated with low birth weight, which may signal underlying health issues in mothers and can lead to cognitive development problems and increased vulnerability to chronic conditions later in life. The authors of the study stress that sustained efforts must be made to address the maternal and neonatal health disparities evident in different regions of India.
