Interaction Between Sarcopenic Obesity and Nonlocomotive Physical Activity on the Risk of Depressive Symptoms in Community-Dwelling Older Adult Japanese Women.

Abstract

This study aimed to investigate the interaction between sarcopenic obesity and locomotive and nonlocomotive physical activity (PA) on the risk of depressive symptoms in community-dwelling older Japanese women. Participants were 143 community-dwelling older women aged 64-94years. PA was measured using a three-axis accelerometer. Participants were classified according to two levels of total, locomotive, and nonlocomotive PA. Depressive symptoms were assessed by a self-administered survey consisting of the 15-item Japanese version of the Geriatric Depression Scale (GDS-15-J). The interaction between sarcopenic obesity groups and total or locomotive PA did not affect GDS-15-J scores. However, the interaction between sarcopenic obesity groups and nonlocomotive PA significantly affected GDS-15-J scores (p < .05). Moreover, sarcopenic obesity in the low PA group had significantly higher GDS-15-J scores compared with sarcopenic obesity in the high PA group (p < .05). We concluded that sarcopenic obesity combined with low nonlocomotive PA may exacerbate depressive symptoms in older women.
