Key result
Greater perceived stressor severity and affective reactivity to daily stressors were associated with lower resting heart rate variability indices, including SDRR (B=-0.05, SE=0.02).
Why the study?
Are trait-like patterns of stress in daily life associated with laboratory-assessed heart rate variability in midlife and older adults?
Population
909 participants aged 35 to 85 years in the Midlife in the United States Study

Daily stress reactivity may relate to lower HRV in midlife adults; hypothesis-generating cross-sectional link leaves causal and clinical implications open.

Are trait-like patterns of stress in daily life associated with laboratory-assessed heart rate variability in midlife and older adults?
Effect estimate: B = -0.05 (SE 0.02) for SDRR
Individual differences in daily negative affect and responses to daily stressors are more strongly related to cardiovascular autonomic regulation than the mere frequency of such stressors.
Sin et al. (2016) conducted a cross-sectional in General population (Midlife and older adults) (n=909). Daily stress processes (perceived severity, affective reactivity, negative affect) vs. Lower levels of daily stress processes was evaluated on Laboratory-assessed heart rate variability (SDRR, RMSSD, and HF-HRV) (B = -0.05 (SE 0.02) for SDRR). Greater perceived stressor severity and affective reactivity to daily stressors were associated with lower resting heart rate variability indices, including SDRR (B=-0.05, SE=0.02).
