Abstract
In a secondary analysis of the TRIUMPH clinical trial, psychological outcomes in patients with resistant hypertension (RH) receiving a diet and exercise intervention delivered in a cardiac rehabilitation setting were compared with those receiving a similar prescription of diet and exercise provided in a single counseling session by a health educator. One hundred forty patients with RH were randomly assigned to a 4-mo program of dietary counseling, behavioral weight management, and exercise (C-LIFE) or a single counseling session providing standardized education and physician advice (SEPA). Participants completed a battery of questionnaires to assess psychological functioning before and after the intervention. A global measure of psychological functioning was derived from the General Health Questionnaire (GHQ), Perceived Stress Scale (PSS), Medical Outcomes Study 36-item Short Form Health Survey, Spielberger State-Trait Anxiety Inventory, Hospital Anxiety and Depression Scale (HADS), Beck Depression Inventory-II, and Patient-Reported Outcomes Measurement Information System (PROMIS) Anger scale. Participants in the C-LIFE intervention achieved greater improvements in psychological functioning compared with SEPA (C-LIFE: 58.9 [56.1, 61.8] vs SEPA: 66.5 [62.1, 70.9]; P = .024). Greater improvements were especially evident for the GHQ, PSS, and HADS. Examination of mediation revealed that greater weight loss ( B =-0.17, P = .004) and improved oxygen uptake ( B =-0.12, P = .044) were associated with improved psychological functioning. Compared with standard education and physician advice, a structured program of diet and exercise not only reduced blood pressure but also improved psychological functioning in patients with RH.
