A significant study has revealed that elderly and middle-aged individuals living with diabetes are at a heightened risk of developing cardiovascular diseases (CVD) due to prolonged exposure to air pollution. The research, conducted by scientists affiliated with Northwest University in Shanxi Province, China, utilized data from the China Health and Retirement Longitudinal Study (CHARLS), tracking 5,430 participants over four years starting in 2011 to establish this critical link. The study found that the prevalence of CVD was considerably higher among diabetic participants (13.8%) compared to non-diabetic individuals (8.5%). Crucially, for every interquartile range increase in pollutant concentration, the risk of cardiovascular disease in the diabetic group escalated by 19% to 28%, with PM10 showing the strongest correlation. Other harmful pollutants considered included PM1, PM2.5, and ozone. The researchers identified the Inflammatory Lipid Ratio (ILR) as a key biomarker, suggesting that elevated ILR values can exacerbate inflammatory responses and lipid metabolism disorders, thereby intensifying cardiovascular disease risk in diabetic patients exposed to air pollution. Although the study was conducted in China, its implications are profoundly relevant for India, a nation grappling with persistently high levels of air pollution and a substantial diabetes burden, estimated to affect approximately 90 million adults. Prior Indian research, notably a landmark study from Delhi and Chennai, has already demonstrated a clear association between exposure to PM2.5 pollution and increased blood sugar levels, contributing to the risk of developing Type 2 diabetes. Health experts consistently highlight that individuals with pre-existing conditions like diabetes, alongside children and the elderly, are particularly vulnerable to the severe and often irreversible health impacts of air pollution, making public health interventions to mitigate exposure critically important.
