Air Pollution and Obesity: A Complex Interplay

While the exact mechanisms are complex, research suggests that chronic exposure to fine particulate matter (PM2.5) can contribute to obesity. This may occur through the induction of insulin resistance, inflammation, and oxidative stress. Additionally, air pollution has been linked to decreased physical activity, further exacerbating weight gain. Interestingly, previous studies have shown a heightened mortality risk from air pollution in individuals who are more physically active, likely due to increased pollutant intake during outdoor activities. Recognizing the intricate interplay between air pollution, physical activity, and weight gain is crucial. This knowledge underscores the importance of mitigating air pollution and promoting healthy lifestyle behaviors to reduce the burden of disease, particularly among older adults, who may be more susceptible to the adverse effects of this environmental hazard.
