Association of waist-calf circumference ratio with frailty by Fried Frailty Phenotype questionnaire in older adults from Japan

Résumé fourni par la source

The waist circumference (WC) to calf circumference (CC) ratio (WCR), a measure of visceral fat, was calculated from WC and CC, measures of abdominal obesity and skeletal muscle mass, respectively. In this study, we investigated the relationship of WCR with pre-frailty and frailty using the Fried Frailty Phenotype Questionnaire (FFPQ). A total of 175 community-dwelling older adults in Wakasa-cho, Kaminaka-Mikata-gun, Fukui Prefecture, Japan were included in this study. Frailty was determined by the FFPQ scores, with those who scored 0, 1-2, and ≥ 3 on the FFPQ being considered robust, pre-frailty, and frailty, respectively. Pre-frailty and frailty were diagnosed in 90 (51.4%) and 18 (10.3%) patients, respectively, using the FFPQ (p < 0.001). CC was not significantly different between the groups (p = 0.415). WCR was significantly higher in the pre-frailty and frailty groups than in the robust group (p < 0.001). The FFPQ scores were significantly positively correlated with WCR (r = 0.364, p < 0.001). Pre-frailty and frailty diagnosed by FFPQ were analysed in relation to WCR, WC, and CC by ordinal logistic regression analysis, which showed that WCR and CC were associated with pre-frailty and frailty after adjustment (WCR: odds ratio (OR) 5.72, 95% confidence interval (CI) 1.43-23.70, p = 0.015; CC: OR 0.81, 95% CI 0.69-0.94, p = 0.006). This study investigated the association of WCR with prefrailty and frailty diagnosed using the FFPQ in community-dwelling older adults. High abdominal fat and low lower leg muscle mass were significantly associated with frailty and WCR during the pre-frailty stage.
