Body mass index, waist-to-hip ratio and cognitive function among Chinese elderly: a cross-sectional study.

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/m² (OR (per 0.1 increase) 1.39; 95% CI 1.13
