Combined effects of habitual exercise and PM2.5 exposure on incident dyslipidemia in adults in Taiwan. The results are fully adjusted for age, sex, educational level, season, baseline calendar year, physical labor at work, smoking status, alcohol consumption, occupational exposure, vegetable intake, fruit intake, BMI, hypertension, diabetes, self-reported cardiovascular disease, and self-reported cancer. Combined effects were analyzedwith participants classified into nine groups according to exercise and PM2.5 exposure categories, with the inactive-exercise group exposed to a high-PM2.5 concentration comprising the reference group. The inactive, moderate, and high levels of exercise were 0, 0.01–8.75, and > 8.75 MET-h, respectively. The low, moderate, and high level of PM2.5 were ≤22.37, 22.37–25.96, and >25.96 μg/m3, respectively. MET, metabolic equivalent of task.
