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.
目的
本研究旨在分析中国老年人腰围（WC）的时间趋势和相关特征。
方法
我们使用了参加中国健康与营养调查（CHNS）的 3096 名≥65 岁成年人的数据，该调查是一项正在进行的队列研究，时间范围为 1993 年至 2015 年。我们使用纵向分位数回归模型来探讨 WC 的时间趋势和相关特征。
结果
在调查期间，中国老年人群体的 WC 逐渐增加。男性和女性的 WC 曲线向右移动，分布变宽，峰值降低。所有 WC 百分位曲线都向上移动，25 百分位、50 百分位和 75 百分位的增长率相似。在我们的研究 22 年期间，WC 均值从 78 厘米增加到 86 厘米。WC 随年龄和体重指数增加而增加，随身体活动（PA）减少而减少。这些关联在较高百分位比在较低百分位更强。
结论
中国≥65 岁成年人的 WC 正在上升。影响老年人 WC 的因素对 WC 分布的不同百分位可能有不同的影响，而 PA 是 WC 分布较高百分位最重要的保护因素。因此，需要采取不同的干预策略。
