CI, confidence interval; GMR, geometric mean ratio; HDL, high-density lipoprotein; PR, prevalence ratio(estimated with robust Poisson regression); T1-T3, tertiles of the total physical activity score. The estimates for β and the GMR are based on a restricted dataset excluding participants with known raised cholesterol and/or triglyceride levels. Estimates are adjusted for age and sex.
^aTriglyceride levels were skewed and therefore log-transformed in the model. The values represent the GMRs compared to each reference group. Low HDL cholesterol < 1.04 mmol/L (< 40 mg/dL) for men and < 1.29 mmol/L (< 50 mg/dL) for women. Raised triglycerides ≥1.7 mmol/L (≥150 mg/dL) or receiving cholesterol/triglycerides lowering medication.
