Does nutritional support under programmatic settings result in weight and body mass index changes among tuberculosis patients? Evidence on the impact of nutritional support through Pradhan Mantri Tuberculosis Mukt Bharat Abhiyan under national tuberculosis elimination programme from Ramgarh district of Jharkhand

Background: To increase community participation in tuberculosis (TB) elimination efforts, the government of India has launched ‘Pradhan Mantri TB Mukt Bharath Abhiyan’ (PMTBMBA) under the national TB elimination programme. The scheme allows interested parties (Ni-kshay mitras) to offer nutritional support to TB patients. This study aims to understand the impact of such a support in improving weight and body mass index (BMI) among TB patients as most available evidence comes from research settings. Methods: This is a retrospective cross-sectional study carried out in Ramgarh district of Jharkhand, India, for the period first quarter 2023. Relevant data was extracted from Ni-kshay web portal and TB treatment cards. The data is analyzed using excel 365. Results: Of the 114 participants, 69 received nutritional support during the entire duration of treatment and 45 received support partially. Single factor ANOVA on weight and BMI gain revealed statistically significant difference in mean weight/BMI between the two groups with F (1, 110)=35.4660, p=3.16×10-08 and F (1, 110)=22.9994, p=5.12×10-06. Correlation analysis showed a moderate correlation between the number of nutritional kits received and the weight/BMI gain with correlation coefficients r=0.5, p=1.07×10-07 and r=0.4, p=1.65×10-05 respectively. Conclusions: The study concludes that the impact of nutritional supplementation in programmatic setting is comparable with that of implementation research study settings.
