Women's participation in stress management interventions for chronic heart failure: a meta-analysis of randomized controlled trials

Stress management interventions (SMIs) can alleviate the psychosocial stress often experienced by women with heart failure. The purpose of this meta-analysis was to summarize women's participation rates, and predictors of participation, in SMIs for the management of psychosocial distress in women with chronic HF. Studies were retrieved from bibliographic databases, reference sections of relevant papers, and research registries. Included studies (a) evaluated a SMI approach for the management of chronic HF, (b) sampled chronic HF patients, and (c) used a randomized controlled trial (RCT) design. Independent coders extracted the relevant data. Thirty-five RCTs met inclusion criteria (N = 3,649; mean age = 63.5 ± 7.0 years). All studies sampled both men and women; the mean proportion of women who participated in the trials was 38.8% (95% confidence interval [CI] = 34.5-43.4; I² = 82.4, 95% CI = 81.0-83.6). Women's participation rates were higher in studies sampling more HF patients with hypertension (B = 1.01, SE = 0.45, P = .046) but fewer HF patients prescribed beta blockers (B = -1.10, SE = 0.33, P = .006), F (2,12) = 6.27, P = 0.014, adjusted R² = 61%. SMIs may offer women a complementary or integrative approach to standard treatment to help manage the psychological distress associated with HF. Future research should explore the potential benefits of offering stress management approaches to women as part of comprehensive HF care.
