Serum triglyceride levels according to leisure-time physical activity by the NOS3 T-786C genotype. Serum triglyceride levels are presented as mean ± SD. Trends of serum triglyceride levels across leisure-time physical activity classes, namely, sedentary, moderately active, and very active, and differences in serum triglyceride levels between the classes were tested after adjustment for age (continuous), sex (male and female), enrollment area (Shizuoka, Aichi, Shiga, Kyoto, Tokushima, Fukuoka, Saga, and Kagoshima), BMI (continuous), fat energy ratio (continuous), smoking habits (never, light, moderate, and heavy), and blood sampling time from last meal (≥ 12 h, 8 h to < 12 h, 4 h to < 8 h, and 2 h to < 4 h) by multiple linear regression analysis. Values of serum triglyceride levels were log-transformed before analysis was carried out. * P < 0.05 compared to the sedentary group in each genotype group.
