Constructing a South Asian cardiovascular disease: a qualitative analysis on how researchers study cardiovascular disease in South Asians

Abstract

BackgroundDebates on the use of race in biomedical research have typically overlooked immigrant groups outside of the black-white racial dichotomy. Recent biomedical research on South Asians and cardiovascular disease provides an opportunity to understand how scientists define race and interpret racial health disparities from an underexamined perspective.PurposeTo examine how researchers in the Mediators of Atherosclerosis in South Asians Living in America (MASALA) study defined a South Asian population, and then compared health differences between South Asians and other populations.MethodsQualitative content analysis was performed on eleven articles from August 2013 to January 2021 that directly compared the South Asian cohort in MASALA to four other groups. The MASALA study design article was also included in this analysis. Articles were analysed for how South Asians were defined, and for how health differences between South Asians and other populations were studied and discussed.ResultsResearchers in MASALA were neither clear nor precise in defining South Asians as either an ancestral group or ethnic group. Their studies also prioritised investigating genetic and molecular causes of the cardiovascular health disparity between South Asians and other populations and failed to examine possible social factors.ConclusionsThese findings reflect a broader trend in biomedical research in which race and racial health disparities are poorly defined and studied, limiting scientists’ understanding of the relationship between race and health. I propose methodologies to help researchers define populations and design studies without relying on biologically reductive assumptions.

The wrong word for the job? The ethics of collecting data on ‘race’ in academic publishing

“…This has been discussed in a recently published student essay by Kawano. 14 He makes an argument in favour of race when collecting data about South Asian cardiovascular disease in the USA. However, he does not suggest that his argument should be extended beyond that case.…”
