The effect of unhealthy lifestyle on the association between adverse childhood experiences and multimorbidity
-
摘要:
目的 探讨童年不良经历(adverse childhood experiences, ACEs)对中老年人共病患病的影响,并进一步分析不健康生活方式在两者关系中的中介效应。 方法 选取2011―2018年中国健康与养老追踪调查队列中的7 513名年龄≥45岁的个体作为研究对象。收集研究对象的年龄和性别等基本资料、ACEs情况、不健康生活方式及慢性非传染性疾病患病资料。采用t检验或χ2检验比较不同特征的中老年人共病患病情况差异,采用非条件logistic回归分析ACEs和不健康生活方式对中老年人共病患病的影响,采用Bootstrap程序检验中介效应。 结果 7 513名研究对象共病患病率为36.34%(95% CI: 35.25%~37.44%)。多因素分析显示,每增加1种ACEs,中老年人共病患病风险增加10.4%(95% CI: 1.058~1.152);与经历1种ACEs的中老年人相比,经历3种和≥4种ACEs的中老年人共病患病风险分别增加38.3%(95% CI: 1.023~1.870)和43.2%(95% CI: 1.065~1.926);每增加1种不健康生活方式,中老年人共病患病风险增加14.4%(95% CI: 1.077~1.216)。与有健康生活方式的中老年人相比,存在≥4种不健康生活方式的中老年人共病患病风险增加99.1%(95% CI: 1.365~2.903)。中介效应分析发现,不健康生活方式的中介效应均无统计学意义(均P>0.05)。 结论 ACEs与中老年人共病患病呈正相关,尚未发现不健康生活方式在中老年人ACEs和共病关联中起中介作用。 Abstract:Objective This study aimed to examine the association between adverse childhood experiences (ACEs) and multimorbidity in middle-aged and older adults, and to investigate whether unhealthy lifestyle mediates this relationship. Methods We analyzed data from 7 513 participants aged ≥45 years in the China Health and Retirement Longitudinal Study from 2011 to 2018. Demographic characteristics, ACEs exposure, unhealthy lifestyle behaviors and chronic disease diagnoses were assessed. Group differences in multimorbidity prevalence were evaluated using t-tests or χ2 tests. Unconditional logistic regression models quantified the effects of ACEs and lifestyle on multimorbidity. Mediation analysis was conducted using the Bootstrap method. Results The prevalence of multimorbidity among the 7 513 participants was 36.34% (95% CI: 35.25%-37.44%). Multivariate analysis revealed that each additional ACE was associated with an 10.4% increase in the risk of multimorbidity (95% CI: 1.058-1.152). Compared to individuals with one ACE, those with 3 and ≥4 ACEs had 38.3% (95% CI: 1.023-1.870) and 43.2% (95% CI: 1.065-1.926) higher risks of multimorbidity, respectively. Additionally, each additional unhealthy lifestyle behavior increased multimorbidity risk by 14.4% (95% CI: 1.077-1.216). Compared to those with healthy lifestyles, individuals with ≥4 unhealthy behaviors had a 99.1% higher risk (95% CI: 1.365-2.903). Mediation analysis revealed that unhealthy lifestyle did not have a significant mediating effect on multimorbidity in middle-aged and older adults (all P>0.05) Conclusions ACEs were positively correlated with multimorbidity, no significant mediating role of an unhealthy lifestyle was found between ACEs and multimorbidity among middle-aged and older adults. -
