NEW DELHI, June 16, 2025 – Despite advancements, low birthweight rates persist in several Indian states, with almost half of such births concentrated in Uttar Pradesh, Bihar, Maharashtra, and West Bengal, according to a study published in BMJ Global Health.
A Persistent Challenge in India
despite overall progress in reducing low birthweight numbers across India, certain states continue to struggle.
- low birthweight is linked to maternal health and future child health issues.
- Four states account for nearly half of all low birthweight births.
- Data quality issues may affect the accuracy of the findings.
The study highlights the continuing challenge of low birthweight in India,a condition often signaling underlying maternal health problems and impacting a child’s future development and susceptibility to chronic conditions. The research underscores the urgent need for continued efforts to address disparities in maternal and neonatal health.
Researchers analyzed data from the National Family Health Survey, spanning from 1992-93 to 2019-21, to understand progress across India. Low birthweight was defined as less than 2,500 g.
Of the 626,087 live births during the study period,birthweight details was missing for some,and a significant portion was assessed subjectively by the mother.
The recorded number of births increased over time, with a rise in the proportion of babies weighed, which improved data quality over the years.
The average prevalence of low birthweight at the state level dropped across surveys, from 25% in 1993 and 1999, to 16% in 2021.The overall prevalence across india decreased from 26% in 1993 to 18% in 2021.
Did you know?-globally, the World Health Institution estimates that 14.6% of all births are low birthweight. This translates to more than 20 million babies each year.
State-Level Variations
In 1993, Rajasthan (48%) and Chhattisgarh (42%) had the highest prevalence of low birthweight, while Mizoram (6%) and nagaland (11%) had the lowest.
By 2021, Punjab and Delhi showed the highest prevalence (22%), while Mizoram (4%), Nagaland (5%), and Manipur (7%) had the lowest.
The 2019-21 survey indicated 4.2 million low birthweight babies in a single year in India. Uttar Pradesh (858,000), Bihar (430,000), Maharashtra (399,000), and West Bengal (318,000) accounted for nearly half (47%) of those births.
Reader question:-What are some effective strategies that you think could help reduce low birthweight rates in your community or region?
states with higher prevalence in 1992-93 saw faster declines, suggesting a degree of convergence.
In 2021, 2.5 million children were born smaller than average size, as assessed by their mothers.
These births were concentrated in Uttar Pradesh (462,000), Bihar (318,000), Maharashtra (261,000), and West Bengal (208,000), accounting for 50% of such births.
Babies with low birthweight or smaller-than-average size were more likely born to women with little or no formal education and from the poorest households.
“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,” the researchers explained.
Looking Ahead
The study shows progress and ongoing challenges. “Our results point to a general decline in the prevalence of low birth weight and convergence between states over time,” thay suggest.
Though, data quality, especially in older surveys, needs consideration, they caution.
Researchers concluded that the persistence of high low birthweight in certain states underlines the need for continued efforts to address health disparities. Improving data collection at health care facilities is also crucial for better decision-making across India.
what does low birthweight signify? Low birthweight frequently enough indicates underlying maternal health issues, poor nutrition, and potential future developmental and chronic health problems for the child.

Delving Deeper: The Root Causes of Low birthweight
While the recent study highlights crucial progress in combating low birthweight in India, a deeper understanding of the underlying causes is essential. Low birthweight, defined as a baby weighing less than 2,500 grams, is not just a statistic. It is a critical indicator of complex issues impacting both the mother and child. These include maternal health, nutrition, access too healthcare, and socioeconomic factors.
Consider the multifaceted nature of maternal health. Pre-existing conditions such as anemia,diabetes,and hypertension,if unmanaged,can substantially increase the risk of low birthweight. inadequate prenatal care,including insufficient check-ups and lack of access to essential micronutrients like folic acid and iron,also contributes to the problem. Poor nutrition during pregnancy is another crucial factor. A diet deficient in essential vitamins and minerals can hinder fetal growth, resulting in babies born smaller than average.
Access to quality healthcare plays a pivotal role. Regular antenatal care allows for early detection and management of potential complications during pregnancy. Deliveries assisted by skilled birth attendants ensure safe childbirth practices, reducing risks. Sadly, many women in India, especially in rural areas, face significant barriers to accessing these vital services. These include geographic limitations, financial constraints, and cultural factors.
Socioeconomic status profoundly influences the likelihood of low birthweight. Women from lower-income households frequently enough experience food insecurity,limited access to healthcare,and poorer living conditions. These challenges can exacerbate the risk factors associated with low birthweight. Education levels also matter. A mother’s level of education frequently enough correlates with her awareness of health practices and her ability to seek timely medical attention.
What are the major drivers of low birthweight? Poor maternal health, inadequate nutrition, lack of access to healthcare, and lower socioeconomic status often lead to low birthweight.
How can we reduce low birthweight rates? Improving maternal health services, promoting good nutrition during pregnancy, and addressing socioeconomic disparities are critical steps.
Breaking Down the Barriers: Practical Steps for Healthier Pregnancies
Addressing the complex issue of low birthweight requires a multifaceted approach. Here are actionable strategies:
- Enhance Maternal Healthcare: Expand access to comprehensive prenatal care, including regular check-ups, screening for health conditions, and management of complications. This involves strengthening public health infrastructure and training more healthcare professionals.
- Improve Nutrition: Implement targeted programs that provide nutritional supplements to pregnant women, especially in vulnerable communities. Promote dietary diversity and educate women about the importance of a balanced diet during pregnancy, offering information on locally available, affordable, and nutritious foods.
- Increase Access to Healthcare: Reduce barriers to healthcare access by establishing more healthcare facilities in underserved areas. Address financial constraints through subsidies or insurance schemes, and promote awareness campaigns to educate communities about the importance of seeking timely medical attention.
- Empower Women Through Education: support initiatives that promote girls’ education and women’s empowerment.Educated women are generally better informed about health practices and more likely to seek appropriate medical care.
- Address Socioeconomic Disparities: Implement poverty reduction programs, provide financial assistance to low-income families, and create job opportunities to improve living conditions. These measures can reduce the stress and challenges faced by pregnant women.
- Strengthen Data Collection and Analysis: Improve the quality and accuracy of data collection at healthcare facilities. This will enable better monitoring of progress, and informed decision-making, allowing for targeted interventions, and the evaluation of the effectiveness of various programs.
By focusing on strategies like these, India can accelerate its progress in reducing low birthweight and improve the health and well-being of future generations. this focused approach is essential not onyl for improving child survival but also for enhancing the overall health and progress of the nation.
