摘      要：Objective This study aimed to analyze the temporal trends and characteristics associated with waist circumference(WC)among elderly Chinese people.Methods We used data from 3,096 adults≥65 years who participated in the China Health and Nutrition Survey(CHNS),an ongoing cohort study,between 1993 and 2015.We used longitudinal quantile regression models to explore the temporal trends and characteristics associated with WC.Results WC increased gradually among the elderly Chinese population during the survey.The WC curves shifted to the right with wider distributions and lower peaks in men and women.All WC percentile curves shifted upward with similar growth rates in the 25th,50th,and 75th percentiles.The WC means increased from 78 cm to 86 cm during the 22 years of our study.WC significantly increased with age and body mass index and decreased with physical activity(PA).These associations were stronger in the higher percentiles than in the lower percentiles.Conclusions WC is rising among Chinese adults≥65 years.Factors affecting WC in elderly people may have different effects on different percentiles of the WC distribution,and PA was the most important protective factor in the higher percentiles of the WC distribution.Thus,different interventional strategies are needed.
