Impact of visceral adiposity index on cognitive impairment and cognitive trajectories in Chinese middle-aged and older adults.

ABSTRACT:

Introduction

The association between the visceral adiposity index (VAI) and cognitive function in middle-aged and older Chinese adults is not well understood. The "obesity paradox"-where obesity appears to be linked with better health outcomes-has also been observed. This study aims to clarify the association by using data from a nationally representative longitudinal survey.

Methods

This study analyzed five waves of data from the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2020. The Cox proportional hazards regression model was used to assess the effect of VAI on the occurrence of cognitive impairment. Additionally, cognitive trajectories over the study period were identified using group-based trajectory modeling (GBTM), and the association between
