“…These studies tend to provide evidence for the stress-buffering hypothesis by reporting reduced cardiovascular reactivity when a supportive "other" is present (see Uchino et al [2011] for a discussion of factors that can moderate this association). Consistent with the stress-buffering hypothesis, Lee et al (2012) found that psychometrically assessed social support was associated with reduced heart rate (HR) reactivity, while Schwerdtfeger and Schlagert (2011) reported lower HR reactivity in those with high perceived social support during an enacted support condition in a sample of young adults. Additionally, Clark (2003) reported that high perceived social support was associated with lower blood pressure reactivity.…”

The benefits of perceived social support for physical and psychological health are well-established. However, little research has explored associations between perceived social support and cardiovascular reactivity in older adults. This exploratory study recruited a sample of older adults (M=69years, SD=5.62) and examined quality and quantity of perceived social support as predictors of cardiovascular reactivity to laboratory-based stress (N=39 participants) and ambulatory cardiovascular activity in everyday life (n=28). The results suggest that quality, but not quantity, of perceived social support predicts reduced blood pressure reactivity to stress in the laboratory. Although quality of support was not associated with ambulatory blood pressure, results suggest that quantity of daily social support may be associated with higher ambulatory heart rate, but not with social contact during measurement. This preliminary study extends prior work on social support and cardiovascular function to a group of older adults in both laboratory and field settings. Challenges for much-needed future research in this area are discussed.

“…We found that racial discrimination was associated with HF‐HRV under stress, even after controlling for baseline HF‐HRV. Some previous data show that chronic psychological vulnerabilities such as low social support (Schwerdtfeger & Schlagert, ) may exert their effect, or exert a stronger effect, under conditions of acute stress. These findings may have clinical significance since it has been demonstrated that HRV responses to laboratory challenge correlate well with HRV response to naturalistic stressors (Dikecligil & Mujica‐Parodi, ).…”

Exposure to Discrimination and Heart Rate Variability Reactivity to Acute Stress among Women with Diabetes

Exposure to racial discrimination has been linked to physiological reactivity. This study investigated self-reported exposure to racial discrimination and parasympathetic [high-frequency heart rate variability (HF-HRV)] and sympathetic (norepinephrine and cortisol) activity at baseline and then again after acute laboratory stress. Lifetime exposure to racial discrimination was measured with the Schedule of Racist Events scale. Thirty-two women (16 Black and 16 White) with type 2 diabetes performed a public speaking stressor. Beat-to-beat intervals were recorded on electrocardiograph recorders, and HF-HRV was calculated using spectral analysis and natural log transformed. Norepinephrine and cortisol were measured in blood. Higher discrimination predicted lower stressor HF-HRV, even after controlling for baseline HF-HRV. When race, age, A1c and baseline systolic blood pressure were also controlled, racial discrimination remained a significant independent predictor of stressor HF-HRV. There was no association between lifetime discrimination and sympathetic markers. In conclusion, preliminary data suggest that among women with type 2 diabetes mellitus (T2DM), exposure to racial discrimination is adversely associated with parasympathetic, but not sympathetic, reactivity.

“…A large body of literature documents a supporting role of the vagus in emotional regulation and pro-social behavior. Adults with high vagal tone show greater self-regulatory capacity [138], better regulation of negative facial expressions [139, 140], increased perceived social support [141], and increased feelings of social integration and acceptance [142]. Vagal tone has also been shown to moderate the impact of negative life experiences, acting as a buffer to shield at risk individuals from negative emotional and physical consequences [143–145].…”

BackgroundAutonomic dysfunction is implicated in a range of psychological conditions, including depression and anxiety. The fragile X mental retardation-1 (FMR1) premutation is a common genetic mutation that affects ~1:150 women and is associated with psychological vulnerability. This study examined cardiac indicators of autonomic function among women with the FMR1 premutation and control women as potential biomarkers for psychological risk that may be linked to FMR1.MethodsBaseline inter-beat interval and respiratory sinus arrhythmia (a measure of parasympathetic vagal tone) were measured in 35 women with the FMR1 premutation and 28 controls. The women completed anxiety and depression questionnaires. FMR1 genetic indices (i.e., CGG repeat, quantitative FMRP, FMR1 mRNA, activation ratio) were obtained for the premutation group.ResultsRespiratory sinus arrhythmia was reduced in the FMR1 premutation group relative to controls. While depression symptoms were associated with reduced respiratory sinus arrhythmia among control women, these variables were unrelated in the FMR1 premutation. Elevated FMR1 mRNA was associated with higher respiratory sinus arrhythmia.ConclusionsWomen with the FMR1 premutation demonstrated autonomic dysregulation characterized by reduced vagal tone. Unlike patterns observed in the general population and in study controls, vagal activity and depression symptoms were decoupled in women with the FMR1 premutation, suggesting independence between autonomic regulation and psychopathological symptoms that is atypical and potentially specific to the FMR1 premutation. The association between vagal tone and mRNA suggests that molecular variation associated with FMR1 plays a role in autonomic regulation.

Abstract: Together, these findings support the assumption that different aspects of social support are related to different physiological processes.
