ABSTRACT
The focus of behavioural sciences in shaping behaviour of individuals and populations is well documented. Research and practice insights from behavioural sciences improve our understanding of how people make choices that in turn determine their health, and in turn the health of the population. However, we argue that an isolated focus on behaviour - which is one link in a chain from macro to the micro interventions - is not in sync with the public health approach which per force includes a multi-level interest. The exclusive focus on behaviour manipulation then becomes a temporary solution at best and facilitator of reproduction of harmful structures at worst. Several researchers and policymakers have begun integrating insights from behavioural economics and related disciplines that explain individual choice, for example, by the establishment of Behavioural Insight Teams, or nudge units to inform the design and implementation of public health programs. In order to comprehensively improve public health, we discuss the limitations of an exclusive focus on behaviour change for public health advancement and call for an explicit integration of broader structural and population-level contexts, processes and factors that shape the lives of individuals and groups, health systems and differential health outcomes.
ABSTRACT
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.
