A cutoff value for body composition on the severity of locomotive syndrome in Japanese older women: A cross-sectional study.

We aimed to investigate the relationship between body compositions and locomotive syndrome in older women and derive body composition cutoff values to evaluate locomotive syndrome severity. In total, 236 women were included in this study. The percentage of body fat and skeletal muscle mass index was measured using multi-frequency bioelectrical impedance analysis. The locomotive syndrome severity (stage 0-3) was determined using the standup test, the two-step test, and a self-administered questionnaire. The receiver operating characteristic curve analysis indicated that the cutoff value for body fat percentage was 33.1% for locomotive syndrome stage 1 in women. This finding may aid in designing exercise and nutritional interventions to prevent locomotive syndrome in older women.
