Increased Cardiometabolic and Mortality Risk Following Childhood Maltreatment in the United Kingdom

BACKGROUND: Childhood maltreatment remains a significant public health issue associated with a number of poor health outcomes. This study explores the association between childhood maltreatment and the subsequent development of cardiometabolic disease and all‐cause mortality. METHODS AND RESULTS: Using a UK primary care database between January 1, 1995 and December 31, 2018, we conducted a population‐based open retrospective cohort study. We matched 80 657 adult patients with a historic recording of childhood maltreatment or maltreatment‐related concerns (exposed group) to 161 314 unexposed patients. Outcomes of interest were the development of cardiovascular disease, hypertension, type 2 diabetes mellitus, and risk of all‐cause mortality. During the study period there were 243 new diagnoses of cardiovascular disease (incidence rate 8.3 per 10 000 person‐years) in the exposed group compared with 254 in the unexposed group (incidence rate 4.6 per 10 000 person‐years). Following adjustment for key covariates, this translated to an adjusted incidence rate ratio of 1.71 (95% CI 1.42–2.06). Additionally, the exposed group had an increased risk of hypertension (adjusted incidence rate ratio 1.42; 95% CI, 1.26–1.59), type 2 diabetes mellitus (adjusted incidence rate ratio 2.13; 95% CI, 1.86–2.45) and all‐cause mortality (adjusted incidence rate ratio 1.75; 95% CI, 1.52–2.02) during the study period compared with the unexposed group. CONCLUSIONS: Considering the high prevalence of exposure to childhood maltreatment, we have demonstrated the substantial associated burden of preventable cardiometabolic disease. There is a clear need to ensure that public health approaches are implemented to prevent the adverse consequences following exposure to childhood maltreatment.
