Efficacy of empowerment strategies for patients with hypertension: A systematic review and meta-analysis.

<bold>Background: </bold>Cardiovascular disease has caused heavy health care burdens in many countries, and hypertension (HTN) is a well-known independent cardiovascular risk factor.<bold>Objective: </bold>To assess the efficacy of empowerment strategies that affect systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), quality of life, and self-management behaviours for patients with hypertension.<bold>Methods: </bold>A literature search of the Cochrane Library, PubMed, MEDLINE, Embase, Web of Science, and several Chinese medical databases was performed. Study screening, quality assessment, data extraction, and meta-analysis were conducted according to Cochrane standards.<bold>Results: </bold>Eleven randomised controlled trials with 988 subjects were identified. Relative to control groups, the empowerment strategies showed significant decreases in SBP (the mean difference [MD] = 9.46, 95 % confidence interval [CI] = 6.36-12.55, p <  0.00001) and DBP (MD = 6.68, 95 % CI = 3.07-10.29, p =  0.0003). However, no significant difference was found in BMI (p = 0.05). Subgroup analysis showed significant differences in the improvement of both SBP and DBP among the various groups, regardless of the duration and type of interventions.<bold>Discussion: </bold>Empowerment strategies can decrease both SBP and DBP in hypertension patients. However, its influence on patients' BMI, quality of life, and self-management behaviour remains unclear.<bold>Practical Value: </bold>Empowerment strategies are useful for controlling the blood pressure of hypertension patients.
