Abstract

Obesity is associated with cognitive decline, yet evidence regarding the role of different obesity indices is heterogeneous. This study aims to investigate the impact of the weight-adjusted waist index (WWI), an indicator providing an optimised assessment of abdominal obesity, on cognition in middle-aged and older adults in China.

Research summary

The study investigates the association between the weight-adjusted waist index and cognitive function in middle-aged and older adults. This research is relevant as it explores factors related to obesity and cognition, which are important in understanding age-related diseases and their potential impact on longevity.
