The association between childhood trauma and lipid levels in an adult low-income, minority population.

BACKGROUND

The objective of this study is to investigate the association between childhood trauma and lipid profiles in adults from a highly traumatized population at-risk for cardiovascular disease.

METHOD

We recruited 452 participants, primarily African-American and of low socioeconomic status, from general medical clinics in a large urban hospital. We performed direct comparisons, univariate analysis of variance and regression analyses together and separated by sex, examining the associations of child abuse, body mass index, lipid lowering drug use, blood pressure, age, and substance use to HDL levels and HDL/LDL ratios.

RESULTS

A history of moderate to severe levels of childhood trauma and abuse was associated with a significant decrease in HDL levels (P ≤ .01) and HDL/LDL ratios (P ≤ .001) relative to males with low levels of abuse. This relationship held when the status of lipid-lowering drugs was considered. When controlling for age, substance abuse, tobacco use, and adult trauma, the effects of childhood trauma remained significant. We found a significant child abuse by sex interaction on HDL/LDL ratios [F(1,369)=13.0, P ≤ .0005] consistent with a differential effect of trauma on dyslipidemia in male but not female subjects.

CONCLUSIONS

Our data suggest that childhood trauma exposure, obtained with self-report measures, may contribute to increased risk of cardiovascular disease by way of stress-mediated alterations of lipid concentration and composition in male, but not female, subjects.
