Independent relationships of daily life activity and leisure-time exercise with metabolic syndrome and its traits in the general Japanese population.

Abstract

This study aimed to investigate independent relationships of daily non-exercise life activity and leisure-time exercise volume and intensity with the prevalence of metabolic syndrome and its traits in Japanese adults. Data of 24,625 eligible subjects (12,709 men, 11,916 women) who participated in the baseline survey of the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study were analyzed. Information about lifestyle characteristics was obtained from a questionnaire. Logistic regression analyses were performed to evaluate the independent associations of daily life activity as well as leisure-time exercise volume and intensity with the prevalence of metabolic syndrome and its traits by sex. Male subjects with higher daily life activity as well as with higher leisure-time exercise volume had a lower prevalence of metabolic syndrome, independently with each other. Female subjects with higher daily life activity also had a lower prevalence of metabolic syndrome. Particularly, male and female subjects with the highest daily life activity quartile showed considerably low odds ratios of 0.66 (95% CI, 0.53-0.81) and 0.64 (0.52-0.79), respectively, for low HDL-cholesterol even after the adjustment for BMI compared with the first quartile. Meanwhile, male subjects with the higher leisure-time exercise showed a quite lower prevalence of elevated triglycerides. Higher moderate-intensity exercise was more intensely associated with a lower prevalence of metabolic syndrome and some of its traits in both sexes. Our results suggest that higher daily life activity and higher moderate-intensity exercise may be independently associated with a lower risk of metabolic syndrome in Japanese adults.
