Outline
Based on the life course theory, this study aims to understand the relationship between adverse childhood experiences (ACEs) and body roundness index (BRI) among Chinese older adults, as well as gender heterogeneity, in order to provide scientific evidence for the formulation of obesity prevention and control policies for older adults.
Data from 7 695 participants in the China Health and Retirement Longitudinal Study (CHARLS, 2013-2015) were analyzed. OLS regression and RCS models were used to assess the linear and dose-response relationships, respectively, and examine gender differences.
Of the 7 695 older adults included in the analysis, those who had experienced ACEs exhibited higher BRI compared to those who had not (β1=0.68, P<0.01;β2=0.74, P<0.01;β3=0.78, P<0.01;β4=0.74, P<0.01). The impact of ACEs on BRI was partially explained by family environment, living conditions, and policy environment, as outlined in the theory of health ecology. The RCS results showed a significant non-linear inverted “J” shaped distribution between ACEs and BRI in the overall population. Gender heterogeneity was observed, with a significant non-linear inverted “U” shaped distribution among males and a significant non-linear relationship among females.
ACEs are significantly linked to BRI in Chinese seniors, with gender differences. This has key implications for policy improvement, emphasizing healthy environments, risk prevention, counseling, and early interventions to reduce future health risks.
