OBJECTIVE: The pathways underlying the early life adversity and cardiovascular reactivity association remain unclear. The current study examined the role of current depressive symptoms on this relationship.
METHODS: Mediation analyses were conducted using data from 639 participants drawn from the Midlife Development in the United States 2 Biomarker Project. Responses were derived from the Childhood Trauma Questionnaire and Center for Epidemiologic Studies Depression Scale. Participants had their systolic and diastolic blood pressure (SBP, DBP) and heart rate monitored throughout a standardized stress testing protocol.
RESULTS: The association between early life adversity and reactivity was mediated by current depressive symptoms; all adversity factors were linked to higher levels of current depressive symptoms, which, in turn, were associated with lower cardiovascular reactivity. For emotional abuse, this was noted for SBP (β = -0.06 [95% confidence interval {CI}, -0.13 to -0.01]) and DBP (β = -0.04 [-0.07 to -0.01]), physical abuse (SBP: β = -0.05 [-0.11 to -0.01]; DBP: β = -0.03 [-0.06 to -0.01]), sexual abuse (SBP: β = -0.04 [-0.09 to -0.01]; DBP: β = -0.02 [-0.05 to -0.01]), emotional neglect (SBP: β = -0.04 [-0.09 to -0.01]; DBP: β = -0.02 [-0.05 to -0.01]), physical neglect (SBP: β = -0.09 [-0.17 to -0.02]; DBP: β = -0.05 [-0.09 to -0.02]), and total Childhood Trauma Questionnaire score (SBP: β = -0.02 [-0.03 to -0.00]; DBP: β = -0.01 [-0.02 to -0.00]).
CONCLUSIONS: The present findings extend research and demonstrate that depression is an underlying mechanism linking early life adversity and blunted cardiovascular reactivity.
