Recent research highlights that while India has made significant strides in reducing the prevalence of low birthweight babies over the past three decades, major disparities persist across states, with four—Uttar Pradesh, Bihar, Maharashtra, and West Bengal—accounting for nearly half of all low birthweight cases nationwide.
According to a study published in the British Medical Journal (BMJ) Global Health, the national prevalence of low birthweight (defined as under 2.5 kg) has declined from 26% in 1993 to 18% in 2021. However, in certain states, as many as one in three newborns still falls below this critical threshold. The 2019–21 National Family Health Survey (NFHS) data revealed that out of approximately 4.2 million low birthweight babies born in a single year, nearly 47% were concentrated in these four states: Uttar Pradesh (858,000), Bihar (430,000), Maharashtra (399,000), and West Bengal (318,000).
Root Causes and Implications
The study underscores that low birthweight is a key indicator of maternal health issues and poor nutrition. It is also linked to challenges in a child’s cognitive development and an increased risk of chronic diseases later in life. The research further notes that babies born to women with little or no formal education and from the poorest households are especially vulnerable to low birthweight, highlighting the interplay between socioeconomic status, access to healthcare, and maternal health.
Progress and Persistent Challenges
While many states—such as Rajasthan and Delhi—have improved and now align with the national average, others continue to lag behind. The researchers emphasize that low birthweight is more prevalent among babies who are not weighed at birth, which correlates with weaker healthcare infrastructure and lower institutional delivery rates.
Looking Ahead
The findings call for targeted interventions in high-burden states, focusing on improving maternal nutrition, expanding healthcare access, and addressing underlying socioeconomic determinants. The researchers highlight the need for continued monitoring and tailored public health strategies to bridge these persistent gaps.
