| Abstract: | The current study investigated high‐frequency heart rate variability (HF‐HRV) as a potential mediator between childhood parental warmth and later health and mortality outcomes. Participants were 1,255 adults (56.9% female). Childhood parental warmth was reported retrospectively at mean age 46; resting HF‐HRV was measured at mean age 57; cardiovascular health and self‐evaluated health were assessed at mean ages 57 and 63, and mortality records extracted at mean age 63. Results revealed a positive association between childhood parental warmth and resting HF‐HRV, as well as associations between higher HF‐HRV and reduced risk of having a later cardiovascular health problem and of mortality by age 63. Mediation analyses revealed a small significant indirect effect of parental warmth, through HF‐HRV, on cardiovascular health. |
