Indiana University-Purdue University Indianapolis (IUPUI) / Epidemiologic studies suggest that depression is an independent risk factor for cardiovascular disease (CVD). Although several possible mediators of this association have been proposed, few studies have examined the role of moderators. Accordingly, I examined adverse childhood experiences (ACE) as a potential moderator of the depression-CVD association, given that individuals with a history of ACE show a greater
inflammatory response to depression, and inflammation plays a role in the development of CVD. Data from Waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were analyzed. Participants were 29,282 adults (58% female, 42% non–white) aged 18–97 years, free of CVD diagnoses at baseline. Lifetime depressive disorder (LDD) was assessed by the Alcohol Use Disorder and Associated Disabilities Interview Schedule–IV (AUDADIS–IV), and adverse childhood experiences (abuse, neglect, and household dysfunction), and CVD were assessed during separate
interviews. The primary outcome was incident CVD (n = 1,255), defined as nonfatal arteriosclerosis, angina pectoris, myocardial infarction, and/or stroke reported during the Wave 2 interviews. All analyses were adjusted for demographic and traditional CVD risk factors. Logistic regression models revealed that both LDD (OR = 1.44, 95% CI: 1.28–1.62, p < .001) and any ACE (OR = 1.25, 95% CI: 1.16–1.35, p < .001) were independent predictors of incident CVD. Interactions between LDD x any ACE (p = .024), LDD x neglect (p = .003), and LDD x household dysfunction (p < .001), but not LDD x abuse (p = 0.16), were detected. Analyses stratified by the ACE variables revealed that LDD was
a predictor of incident CVD among adults with a history of (1) any ACE (OR = 1.51,
95% CI: 1.32–1.73, p < .001), but not among those without a history (OR = 1.15, 95% CI: 0.87–1.50, p = .332); (2) neglect (OR = 1.59, 95% CI: 1.36–1.87, p < .001) and among those without a history (OR = 1.25, 95% CI: 1.07–1.62, p = .005); (3) household dysfunction (OR = 1.73, 95% CI: 1.46–2.04, p < .001), but not among those without a history (OR = 1.18, 95% CI: 0.96–1.43, p = .11). Overall, the present findings suggest that depression may be a stronger risk factor for CVD among adults with a history of ACE, especially neglect and household dysfunction, than among adults who did not have these experiences.
