India faces persistent challenges wiht low birth weight despite overall progress,finds a new study.While the rate of smaller babies is dropping, disparities persist, especially among underserved communities. Uttar Pradesh,Bihar,Maharashtra,and West bengal account for a significant portion of these births,with poverty and lack of education linked to the prevalence of low birth weight. Researchers also emphasize the importance of better data collection to address this critical issue. From the News Directory 3 team, this analysis dives into the state-wise trends, highlighting the urgent need for improved maternal and neonatal healthcare. Discover what’s next for India’s efforts to combat low birth weight.
Low Birth Weight Still a Challenge in India Despite Progress
updated June 16, 2025
Despite overall improvements, low birth weight remains a notable concern in certain Indian states, according to a recent survey. While there has been a general decline in teh prevalence of low birth weight babies across India, disparities persist, particularly among women with little or no formal education and those from the poorest households.
the study, which examined trends over nearly three decades, indicated a convergence among states, with those having higher rates of low birth weight in the early 1990s experiencing faster declines. Though,researchers caution that data quality issues,especially in older surveys,require careful interpretation of specific numbers.
In 2021, approximately 2.5 million children were born smaller than average size, as reported by their mothers. Uttar Pradesh (462,000), Bihar (318,000), Maharashtra (261,000), and West Bengal (208,000) accounted for 50% of these births. These same four states also have a high prevalence of low birth weight babies; babies weighing less than 2.5 kilograms (5.5 pounds) at birth in these states—Uttar Pradesh (21%), Bihar (13%), Maharashtra (7%) and West Bengal (6%)—accounted for nearly half (47%) of all such births.
Researchers suggest that the prevalence of low birth weight might potentially be even higher than reported, as non-weighed children are more likely to be underweight, and weighing is closely linked to health care access. They added that low socioeconomic status contributes to both limited health care access and low birth weight.
“Low birth weight is highly likely to be more prevalent among non-weighed children, as weighing correlates strongly with health care infrastructure and being born in a health facility. Also, low socioeconomic status is linked to both lack of access to health care and low birth weight,” explain the researchers.
The study highlights the need for continued efforts to address maternal and neonatal health disparities in states with persistently high rates of low birth weight. Researchers emphasize the importance of enhancing data collection at health care facilities to ensure quality data for informed decision-making across India.
What’s next
Ongoing efforts to improve maternal and neonatal health, particularly in states with high prevalence of low birth weight, are crucial. Enhancing data collection at healthcare facilities will provide better insights for decision-making and resource allocation.
