The associations between adverse childhood experiences and body pain among middle-aged and older adults: findings from China

Abstract

Abstract Background Adverse Childhood Experiences (ACEs) have been implicated in the development of body pain, yet research on their impact on body pain and its progression remains scarce. This study aimed to examine the associations between ACEs and the presence and areas of body pain, as well as their developmental trajectories among middle-aged and older Chinese adults. Methods We included participants aged 45 years and above from the China Health and Retirement Longitudinal Study (CHARLS) conducted between 2011 and 2018. Retrospective data on ACEs and pain sites were collected with questionnaires. The presence of pain at different body sites was categorized into three areas: head & neck, trunk, and limbs. ACEs consisted of ten types of adverse experiences and were cumulatively scored. For the cross-sectional analysis (2011), logistic regressions were performed to estimate the associations between ACEs and pain presence in specific areas. In the longitudinal analysis (2011–2018), we further applied group-based trajectory modelling (GBTM) to determine the developmental trajectories of body pain. Multinomial logistic regressions were then conducted to estimate the associations between ACEs and pain trajectories. Results In the cross-sectional analysis (n = 8157), ACEs were positively associated with the presence of pain in the head & neck (odds ratio [OR] = 3.55, 95% confidence intervals [CI] = 2.37–4.74), trunk (OR = 3.28, 95% CI = 2.47–4.34), and limbs areas (OR = 2.30, 95% CI = 1.77-3.00) compared to no ACEs. These associations varied by sex and residence. In the longitudinal analysis (n = 5188), GBTM identified three developmental trajectories of body pain (n = 9521): high-increasing (7.44%), low-moderate (33.67%) and maintained-low trajectories (58.89%) trajectories. Compared to participants without ACEs, individuals had three ACEs and 4 or more ACEs were consistently associated with low-moderate (three ACEs: OR = 2.26, 95% CI = 1.81–2.83, four or more ACEs: OR = 3.11, 95% CI = 2.51–3.87) and high-increasing (three ACEs: OR = 3.28, 95% CI = 2.03–5.30, four or more ACEs: OR = 6.78, 95% CI = 4.30-10.68) body pain trajectories across sexes and residence. Conclusion This study highlighted the significant association between ACEs and body pain among middle-aged and older Chinese, emphasizing the importance of preventing or mitigating ACEs as a strategy for the prevention and management of body pain.
