Abstract: 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 different groups (χ2=86.659, P<0.001). Multivariate Logistic regression analysis showed that overweight and obesity were independent risk factors 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.
