Examining the effect of various factors such as class, gender, and status on health inequalities in India is crucial for improving access to health services. However, most research on castes in India is done using broad, government-defined categories, including “Scheduled Castes,” “Scheduled Tribes,” “Forward Classes,” and “Other Backwards Classes.” These general categories erase the experiences that more specific caste groups have in their health and their livelihood. Using the 2015-2016 Demographic and Health Survey of India, this study analyzes data on 699,686 women aged 15-49 to investigate the association of socioeconomic status, assessed by wealth, education, and community status on two types of contraceptive use–sterilization and other modern methods. Those with secondary education or higher were much less likely to be sterilized and more likely to use non-sterilization forms of modern contraception. Interestingly, those with greater household wealth were more likely to be sterilized but had no different chance of using non-sterilization forms of modern contraception. After controlling for other socioeconomic factors, members of Scheduled Castes and Backward Classes are more likely to be sterilized. However, there was additional heterogeneity between groups, with Muslim groups and Northeastern tribes much less likely to be sterilized, and Southern tribes more likely to be sterilized. Moreover, Muslim groups as well as Northern and Northeastern tribes were more likely to use non-sterilizations forms of contraception, whereas Southern tribes were less likely to use non-sterilization forms of contraception. These findings illustrate that in addition to differences by major caste categories, there is still religious and regional variation in the likelihood of using different forms of contraception. Future research should examine how unique community factors erased within the already present government caste system can affect health. In addition, more research should be done on the various effects of discrimination faced by these communities and how this discrimination affects their health education, access, and autonomy.

Fumonisins are fungal metabolites found in corn and cereals. Fumonisins pose health risks, including suspected carcinogenicity, yet their mechanism of toxicity remains unclear. While modifications in the human gut microbiome can impact host health, the effects of fumonisins on the microbiome are not well understood. Thus, our study aimed to assess a possible dose-response relationship between fumonisin B1 (FB1) and the gut microbiome. We utilized in vitro anaerobic bioreactors with media simulating most of the nutrients in the human large intestine, inoculated them with fecal samples from 19 healthy adults and treated them with FB1 at concentrations of 0, 10, 100, and 1000 ppb. Analyses of bioreactor headspace revealed declining methane production over time, possibly influenced by the addition of dimethyl sulfoxide (DMSO). Significant differences in acetic acid production were observed in 10 ppb reactor (Day 2) and 100 ppb reactor (Day 8) when compared to 0 ppb control. Microbiome analysis showed minimal shifts in microbial relative abundances during FB1 treatment, except for Desulfovibrio desulfuricans C at Day 8 when compared between 0 ppb and 10 ppb as well as 10 ppb and 1000 ppb at Day 16. Alpha diversity analyses indicated significant differences in observed features within bioreactors of different treatments, with some variation in Faith’s Phylogenetic Diversity between the 0 ppb and 10 ppb bioreactors. Beta diversity analyses, however, revealed no significant differences between bioreactors. Overall, our findings suggest no clear dose-response relationship between FB1 treatment and gut microbiome composition/functions. The presence of DMSO may have obscured potential effects. This research will help contribute to our understanding of mycotoxicity influence on the human gut microbiome.
