Abstract
OBJECTIVES
To investigate the associations between body mass index (BMI), waist-to-hip ratio (WHR) and cognitive function among Chinese elderly.
DESIGN
Cross-sectional study.
SETTING
Community.
PARTICIPANTS
Data were obtained from the baseline survey of a community-based cohort in Zhejiang Province, and 9326 persons aged 60 years and older were enrolled.
PRIMARY OUTCOME MEASURES
We investigated the association between BMI and cognition, and then explored the association between WHR and cognition across different quartiles of BMI.
RESULTS
A sample of 9087 persons was used in this study, including 4375 men and 4712 women. Higher WHR increased cognitive impairment risk in those with BMI >25.3 kg/m (OR (per 0.1 increase) 1.39; 95% CI 1.13 to 1.70). No statistically significant association was found in other BMI categories.
CONCLUSIONS
Higher WHR could increase the risk of cognitive impairment among elderly with BMI >25.3 kg/m. Our results suggest that it could be of benefit to the elderly with high BMI to control WHR.
摘要
目的
调查中国老年人的体重指数（BMI）、腰臀比（WHR）与认知功能之间的关联。
设计
横断面研究。
地点
社区。
参与者
数据来自浙江省基于社区的队列的基线调查，共纳入 9326 名 60 岁及以上的老年人。
主要观察指标
我们研究了 BMI 与认知功能的关系，然后探讨了不同 BMI 四分位组中 WHR 与认知功能的关系。
结果
本研究共纳入 9087 人，其中男性 4375 人，女性 4712 人。在 BMI＞25.3kg/m²的人群中，较高的 WHR 增加了认知障碍的风险（OR（每增加 0.1）1.39；95%CI 1.13 至 1.70）。在其他 BMI 类别中未发现统计学显著关联。
结论
较高的 WHR 可能会增加 BMI＞25.3kg/m²的老年人认知障碍的风险。我们的结果表明，对于 BMI 较高的老年人来说，控制 WHR 可能会带来益处。
