To evaluate the relationship between waist-to-hip ratio (WHR) and fall-related outcomes in community-dwelling individuals aged 55 and above.
Cross-sectional data obtained from the first wave of the Malaysian Elders Longitudinal Research (MELoR) study were utilized for this study. Participants aged 55 years and over were recruited using simple random sampling from the electoral rolls of three local parliamentary constituencies. Socio-demographics, falls history and medical history were obtained through home-based computer-assisted interviews while anthropometric measurements, including WHR, and physical performance were obtained during hospital-based health checks. WHR was categorized into three arbitrary categories stratified by gender.
Data on both falls and WHR were available for 1335 participants, mean age ± standard deviation (SD) = 68.4 ± 7.1 years. Logistic regression analyses using dummy variables revealed that individuals within the higher WHR group were significantly more likely to report a history of fall in the preceding 12 months {adjusted odds ratio (aOR) [95% confidence interval (CI)] = 1.78 (1.18-2.67)}, fear of falling [aOR (95% CI) = 1.58 (1.08-2.32)], impaired timed-up-and-go [2.14 (1.44-3.17)] and reduced functional reach [1.68 (1.18-2.38)] compared to those with lower WHR. A higher WHR remained independently associated with increased risk of falls compared to those with lower WHR after additional adjustment for fear of falling and functional performance.
Our finding suggests WHR as an independent risk factor for higher risk of fall which may indicate body shape as a potentially modifiable risk factor for falls in adults in aged 55 years and over.
评估55岁及以上社区居住个体的腰臀比（WHR）与跌倒相关结局之间的关系。
本研究使用了从马来西亚老年人纵向研究（MELoR）第一波中获得的横断面数据。采用简单随机抽样从三个当地议会选区的选民名单中招募55岁及以上的参与者。通过家庭计算机辅助访谈获取社会人口统计学、跌倒史和病史，同时在医院健康检查期间获取人体测量数据，包括腰臀比和身体表现。腰臀比按性别分为三个任意类别。
1335名参与者提供了跌倒和腰臀比数据，平均年龄±标准差（SD）=68.4±7.1岁。使用虚拟变量的逻辑回归分析显示，与腰臀比低的个体相比，腰臀比高的个体在前12个月内报告跌倒史的可能性显著更高{调整优势比（aOR）[95%置信区间（CI）]=1.78（1.18 - 2.67）}，害怕跌倒[aOR（95%CI）=1.58（1.08 - 2.32）]，计时起立行走功能受损[2.14（1.44 - 3.17）]和功能性伸展降低[1.68（1.18 - 2.38）]。在对害怕跌倒和功能表现进行额外调整后，与腰臀比低的个体相比，较高的腰臀比仍然独立地与跌倒风险增加相关。
我们的研究结果表明腰臀比是跌倒风险较高的独立危险因素，这可能表明身体形态是55岁及以上成年人跌倒的潜在可改变危险因素。
