Social determinants of tuberculosis: context, framework, and the way forward to ending TB in India

Introduction Social determinants are involved in the causation of TB and its adverse outcomes. This review was conducted to evolve a framework for action on social determinants with special reference to India in the context of the new END TB strategy. Areas covered We reviewed the social context of TB in India as a neglected disease of the poor, its emergence in epidemic form in the colonial period, and the factors that resulted in its perpetuation and expansion in post-independence India. We examined the role of social determinants in two key pathways - the pathway of TB causation and its outcomes, and the care cascade for patients with TB, and its consequences. We reviewed the most important social determinants of TB including poverty, membership of certain castes and indigenous population, undernutrition and poor access to healthcare, especially in rural areas. Expert opinion We suggest that TB elimination will require an optimal mix of enhanced biomedical and social interventions. TB elimination strategy in India needs a pro-poor model of patient - centered care inclusive of nutritional, psycho-social and financial support, universal health coverage, and social protection; and convergence with multi-sectoral efforts to address poverty, undernutrition, unsafe housing, and indoor pollution.

Automated summary

The study found that social determinants play a significant role in the causation and outcomes of TB in India, indicating that a combination of enhanced biomedical and social interventions is necessary for TB elimination.
