Abstract Objective: Although BMI is associated with sarcopenia, factors that modify this association are unclear. This study aimed to clarify how demographic and lifestyle factors affect the association between BMI and sarcopenia in middle-aged and older adults. Design: A 9-year follow-up study. Setting: Community-based cohort in Japan. Participants: A total of 6632 individuals aged 40–74 years participated in this study. BMI, demographic and lifestyle factors and disease history were assessed in a baseline survey conducted between 2011 and 2014. Sarcopenia was not assessed at baseline. Sarcopenia status was assessed based on the diagnostic criteria of the Asian Working Group for Sarcopenia 2019 during follow-up examinations conducted in 2021 and 2022. The OR for the presence of sarcopenia at follow-up was calculated using multivariable logistic regression analysis. Results: A lower BMI was associated with a higher odds of sarcopenia in both males and females ( P for trend < 0·0001). Significant interactions were observed between BMI and age ( P for interaction = 0·0003) and between BMI and physical activity (PA) level ( P for interaction = 0·0272), in sarcopenia. Specifically, the odds of sarcopenia among underweight individuals (< 18·5 kg/m 2 ) were significantly higher than that of their counterparts in the subgroup aged < 68 years and in the subgroup with high total PA (≥ 40·1 MET-h/d). Conclusions: Low BMI is strongly associated with sarcopenia, and this relationship is modified by age and PA level. Specifically, the adverse impact of being underweight on sarcopenia was greater among middle-aged individuals and those with high PA levels.
