The waist-calf circumference ratio (WCR) is an index that combines waist and calf circumference measurements, offering a potentially effective method for evaluating the imbalance between abdominal fat and leg muscle mass in older adults. To assess the association between WCR and indicators of body composition, muscle strength, and physical performance in community-dwelling older women. This was a cross-sectional study involving 133 older women (≥65 years) from an urban-marginal community in Guayaquil, Ecuador. The WCR was categorized into quartiles (Q1: 2.07-2.57; Q2: 2.58-2.75; Q3: 2.76-3.05; Q4: 3.06-4.76). Body indicators included fat-free mass (FFM), skeletal muscle mass (SMM), appendicular muscle mass (ASM), appendicular muscle mass index (ASMI), visceral fat (VF), fat mass (FM), and fat mass index (FMI). Handgrip strength (HGS) and the Short Physical Performance Battery test (SPPB) score were used to assess muscle strength and function, respectively. The median age of the participants was 75 [IQR: 65-82] years. The mean WCR was 2.92 ± 0.93. Statistically significant associations were found between WCR and VF ( < 0.001), WCR and SMM ( = 0.039), and WCR and ASM ( = 0.016). Regarding muscle function, WCR was associated with HGS ( = 0.025) and SPPB score ( = 0.029). A significant association was observed between WCR and body composition, and muscle strength and function in older women.
腰小腿围比（WCR）是一种综合了腰围和小腿围测量值的指标，为评估老年人腹部脂肪与腿部肌肉量之间的失衡提供了一种潜在有效的方法。旨在评估社区居住的老年女性中WCR与身体成分、肌肉力量和身体机能指标之间的关联。这是一项横断面研究，涉及来自厄瓜多尔瓜亚基尔一个城市边缘社区的133名老年女性（≥65岁）。WCR被分为四分位数（Q1：2.07 - 2.57；Q2：2.58 - 2.75；Q3：2.76 - 3.05；Q4：3.06 - 4.76）。身体指标包括去脂体重（FFM）、骨骼肌量（SMM）、附属肌肉量（ASM）、附属肌肉量指数（ASMI）、内脏脂肪（VF）、脂肪量（FM）和脂肪量指数（FMI）。握力（HGS）和简短身体机能测试电池测试（SPPB）得分分别用于评估肌肉力量和功能。参与者的年龄中位数为75岁[四分位间距：65 - 82岁]。平均WCR为2.92±0.93。发现WCR与VF（<0.001）、WCR与SMM（=0.039）以及WCR与ASM（=0.016）之间存在统计学显著关联。关于肌肉功能，WCR与HGS（=0.025）和SPPB得分（=0.029）相关。在老年女性中，观察到WCR与身体成分、肌肉力量和功能之间存在显著关联。
