目的 分析社区老年人体质量指数(BMI)与虚弱的关系,为超重和肥胖老年人预防乃至延缓虚弱进程提供依据.方法 2016年3月至11月,采用方便抽样的方法,将郑州市1571名老年人作为研究对象,根据BMI分为未超重、超重、肥胖三组,采用Fried虚弱量表进行调查.结果 郑州市社区老年人超重率和肥胖率分别为38.6%、10.9%;不同BMI组间,虚弱水平有非常高度显著性差异(χ2=86.659,P<0.001).Logistic回归分析显示,超重和肥胖是虚弱前期的危险因素(P<0.05),肥胖是发生虚弱的危险因素(P<0.05).结论 郑州市老年人超重率和肥胖率较高,控制体质量或可有效降低虚弱的发生率,延缓虚弱进程.%Objective To explore the relationship between body mass index (BMI) and frailty among community aged people. Methods A total of 1571 aged people in two communities in Zhengzhou, Henan, China were recruited by convenience sampling method. They were divided into normal group, overweight group and obesity group according to BMI, and were assessed with Fried Frailty Criteria. Results The rates of overweight and obesity were 38.6%and 10.9%, respectively. There was significant difference in the level of frailty among dif-ferent groups (χ2=86.659, P<0.001). Multivariate Logistic regression analysis showed that overweight and obesity were independent risk fac-tors of pre-frailty (P<0.05), and obesity was the independent risk factor of frailty (P<0.05). Conclusion The prevalence of overweight and obesity was higher in community aged people in Zhengzhou, and normal BMI was important to postpone the process of frailty.
