Objective: Little is known about the cardiovascular effects of mutual emotional spousal support given for health concerns. We examined the hypotheses that: (a) mutual support (both spouses giving and receiving support) compared to one-sided or no support, would decrease blood pressure and heart rate in both spouses during a recovery period; and (b) wives would benefit more from mutual support than would husbands. A second aim was to examine gender differences in cardiovascular reactivity, distress, and closeness in response to receiving support regardless of mutuality. Method: In 98 married couples (Age 50+), spouses discussed health concerns and were assigned randomly to one of four conditions: neither spouse received support (n = 26), only the wife received support from the husband (n = 22), only the husband received support from the wife (n = 23), or both received support (n = 27). Systolic and diastolic blood pressure and heart rate were measured during baseline, the discussions, and recovery. Distress, closeness, and support were self-reported. Support quality was observationally coded. Results: Mutual support did not affect cardiovascular reactivity. When husbands received support from wives, husbands’ blood pressure and distress decreased, and both partners’ closeness increased. When wives received support, husbands and wives felt closer, but both partners’ heart rate remained elevated and wives felt more distressed. Conclusions: Receiving support individually may be more important than receiving support mutually for older adult spouses coping with their health concerns. Also, support interventions for couples coping with health conditions should take into account that husbands receive greater benefits from spousal support than wives.

Stress may contribute to illness through the impaired recovery or sustained activity of stress-responsive biological systems. Rumination, or mental rehearsal of past stressors, may alter the body’s stress-responsive systems by amplifying and prolonging exposure to physiological mediators, such as cortisol. The primary aim of the current investigation was to test the extent to which the tendency to ruminate on stress predicts diminished diurnal cortisol recovery (i.e., elevated evening cortisol) in a sample of sexual and gender minority young adults. Participants included 58 lesbian, gay, bisexual, and transgender young adults (Mage = 25.0, SD = 4.1) who completed an initial online survey that assessed trait rumination and current depressed mood. Participants completed daily evening questionnaires and provided salivary cortisol samples at wake, 45 min post-wake, 12 h post-wake, and at bedtime over seven consecutive days. Trait rumination predicted significantly higher cortisol concentrations at bedtime, but was unrelated to other cortisol indices (e.g., morning cortisol, diurnal slope, total output). The association with trait rumination was not accounted for by daily negative affect, and was largely independent of depressed mood. These results have implications for identifying and treating those who may be at risk for impaired diurnal cortisol recovery and associated negative health outcomes.

Disclosure to family members uniquely predicted cortisol AUCg. Therefore, these results suggest that effects of disclosure on diurnal cortisol and its associated health outcomes may occur in the context of familial relationships.
