Theory and health disparities: Explaining the relevance of theory in public health research in India

This paper aims to address the concern that quantitative public health studies do not integrate theoretical considerations. This qualitative study uses content analysis to explore the application of theory in Indian public health articles listed on PubMed. Social determinants such as poverty, income, social class, education, gender, caste, socioeconomic position, socioeconomic status, immigrant status, and wealth were the keywords used to identify the articles analysed in this study. From a selection of 91 public health articles, we identified potential theoretical frameworks based on the pathways/recommendations/explanations mentioned. Additionally, using the case of tuberculosis in India, we highlight how theoretical perspectives play a critical role in providing a holistic view of major health challenges. Finally, by emphasising the need to adopt a theoretical perspective in empirical quantitative research on public health in India, we hope to motivate scholars to include a theory or theoretical paradigm in their future research.
