Effect of caste on health, independent of economic disparity: evidence from school children of two rural districts of India

Health disparity at the intersection of religion and caste: Evidence from India

Objective

The provisions and recognition of Schedule Castes (SCs), the constitutional term for the Dalits in India, have been exclusively extended to Hindus, Buddhists, and Sikhs (HBS). Omission of Dalit Muslims and Christians (MC) from the SC category stripped them of the affirmative action benefits tied with the SC status. This study aimed to explore how such differential treatment might play a role in differential health outcomes in Dalit women in India.

Methods

Drawing data on 177,346 Dalit women, aged 20 to 49 years, from two successive nationally representative surveys, we assessed the differential likelihood of hypertension and diabetes, between MC- and HBS- Dalit women. Accounting for birth cohort-, survey wave-, and state of residence- fixed effects, along with socioeconomic conditions and cardiometabolic risk factors, we obtained adjusted odds of having hypertension and diabetes in MC women. To check the validity of our results, we conducted similar analyses using data on 170,889 Scheduled Tribe (ST) women, another marginalized group, whose ST-status recognition were not tied to religion.

Results

We found that Dalit MC women were 1.13 (95% CI: 1.03-1.25) and 1.19 (95% CI: 1.05-1.36) times more likely to have hypertension and diabetes, respectively, compared to Dalit HBS women. Conversely, no statistically significant differential likelihood of these conditions was observed between MC and HBS women in the ST sample.

Conclusion

Our investigation thus, indicated a potential link at the crossroads of religion and caste that may contribute to the health disparities among marginalized women in India.

Racism, xenophobia, and discrimination: mapping pathways to health outcomes

Despite being globally pervasive, racism, xenophobia, and discrimination are not universally recognised determinants of health. We challenge widespread beliefs related to the inevitability of increased mortality and morbidity associated with particular ethnicities and minoritised groups. In refuting that racial categories have a genetic basis and acknowledging that socioeconomic factors offer incomplete explanations in understanding these health disparities, we examine the pathways by which discrimination based on caste, ethnicity, Indigeneity, migratory status, race, religion, and skin colour affect health. Discrimination based on these categories, although having many unique historical and cultural contexts, operates in the same way, with overlapping pathways and health effects. We synthesise how such discrimination affects health systems, spatial determination, and communities, and how these processes manifest at the individual level, across the life course, and intergenerationally. We explore how individuals respond to and internalise these complex mechanisms psychologically, behaviourally, and physiologically. The evidence shows that racism, xenophobia, and discrimination affect a range of health outcomes across all ages around the world, and remain embedded within the universal challenges we face, from COVID-19 to the climate emergency.
