| Outline of Final Research Achievements |
Although smoking is a well-known risk factor of sarcopenia, the mechanism remains unclear. If peroxidation is involved, anti-oxidants such as carotenoids might have preventive effects on sarcopenia, especially in smoking population. The aim of this study is to clarify the interactive effects of carotenoids and smoking on muscle mass decline with aging. The subjects were the participants in a population-based longitudinal cohort study. Mixed effects models were used to estimate whether carotenoids, smoking and their interaction influenced muscle mass decline with aging. The main outcomes were; smoking showed progressive effects, whereas several serum carotenoids showed preventive effects on muscle mass decline with aging in males, but not in females. Moreover, interaction between beta-cryptoxanthin intake and smoking was observed. Beta-cryptoxanthin intake may prevent the muscle mass decline in male smokers.
