Association Between Child Abuse and Risk of Adult Coronary Heart Disease: A Systematic Review and Meta-Analysis

Abstract

Introduction: This meta-analysis aimed to examine the association of child abuse with adult coronary heart disease risk and separately by abuse subtypes, including emotional abuse, sexual abuse, and physical abuse.

Methods: Data were extracted from studies published up through December 2021 and on the basis of research from PubMed, Embase, CINAHL, and PsycINFO. Studies were selected if they included adults with or without any type of child abuse and measured the risk of any type of coronary heart disease. Statistical analyses were conducted in 2022. The random effects model was used to pool the effect estimates presented by RRs with 95% CIs. Heterogeneity was assessed using Q and I² statistics.

Results: The pooled estimates were synthesized using 24 effect sizes from 10 studies with a sample size of 343,371 adults. Adults with child abuse were associated with a higher risk of coronary heart disease than those without (RR=1.52; 95% CI=1.29, 1.79), and the association was similar for myocardial infarction (RR=1.50; 95 % CI=1.08, 2.10) and unspecified coronary heart disease (RR=1.58; 95% CI=1.23, 2.02). Moreover, emotional (RR=1.48; 95% CI=1.29, 1.71), sexual (RR=1.47; 95% CI=1.15, 1.88), and physical (RR=1.48; 95% CI=1.22, 1.79) abuse were associated with increased risk of coronary heart disease.

Discussion: Child abuse was associated with an increased risk of adult coronary heart disease. Results were generally consistent across abuse subtypes and sex. This study advocates further research on biological mechanisms linking child abuse to coronary heart disease as well as improvement in coronary heart disease risk prediction and targeted prevention approaches.
