Providing nutritional support to 2.8 million tuberculosis (TB) patients in India could prevent more than 1,20,000 deaths every year, according to a new study. Researchers highlight that food-based interventions can significantly improve survival rates while remaining more cost-effective than many traditional biomedical approaches. Pranay Sinha noted that for a relatively low cost, such interventions could save over 100,000 lives annually, making nutrition a powerful yet underutilised tool in TB control.
Strong Evidence from National and Global Collaboration
The study, conducted in collaboration with National Tuberculosis Elimination Programme, found that nutritional support improves health outcomes in 94% of simulated scenarios. The findings have been published in BMJ Global Health, further strengthening the evidence base for integrating nutrition into TB care strategies. Researchers compared standard TB care with a household-level food basket intervention, drawing on multiple datasets and systematic reviews to validate their conclusions.
Undernutrition: A Root Cause of Tuberculosis
The study identifies undernutrition as one of the most significant modifiable risk factors for TB. Poor nutrition weakens immunity, increases the risk of treatment failure, and raises mortality rates. Urvashi Singh emphasised that undernutrition is not just a consequence but a root cause of TB. She pointed out that while the world awaits more effective vaccines, food itself can act as a preventive and therapeutic tool.
Measurable Health Gains and Cost Effectiveness
The study projects substantial health benefits from nutritional interventions. Specifically, providing food support could avert 10,470 disability-adjusted life years (DALYs) per 10,000 TB patients. When scaled to India’s annual TB burden, this translates to approximately 1,20,120 deaths prevented nationwide under full coverage. Moreover, each health gain would cost around USD 141—well below India’s cost-effectiveness benchmark of USD 550. This makes nutritional support not only impactful but also a highly efficient public health investment.
Bridging Research and Policy
Julia Gallini explained that the study aims to provide policymakers with clear, data-driven insights into the national impact of nutritional support. By quantifying outcomes, the research strengthens the case for integrating food assistance into TB elimination strategies.
Supporting Evidence from Previous Studies
The findings align with earlier research published in The Lancet in August 2023. That study showed that providing protein-rich food and multivitamins reduced new TB cases among family members by nearly 50%. The RATIONS trial, conducted across multiple TB units in Jharkhand, further demonstrated that household-level nutritional interventions can significantly curb transmission and improve outcomes.
Policy Context: India’s TB Elimination Efforts
India’s TB control programme has evolved significantly over the years. In 2020, the Revised National Tuberculosis Control Programme was renamed as the National Tuberculosis Elimination Programme, reflecting a stronger commitment to eradicating the disease. However, the study suggests that achieving elimination goals will require a broader approach—one that combines medical treatment with social and nutritional support.
As reported by ndtv.com, the evidence is clear: nutritional support can play a transformative role in reducing TB-related deaths in India. By addressing undernutrition, policymakers can tackle one of the root causes of the disease while improving treatment outcomes. As India continues its fight against tuberculosis, scaling up food-based interventions could prove to be one of the most impactful and cost-effective strategies for saving lives and accelerating progress toward elimination.
