How effective are hypertension self-care interventions?

Simplification of the dosing regimen (eg, once-daily instead of multiple dosing) improves patients’ adherence to antihypertensive medications (strength of recommendation [SOR]: B, based on a high-quality systematic review of lower-quality randomized controlled trials). Dietary advice promotes modest short-term improvements in self-reported fat intake and fruit and vegetable consumption (SOR: B, based on a high-quality systematic review of lower-quality, randomized controlled trials). Educational interventions alone, in general, do not improve patient adherence to antihypertensive medication regimens (SOR: B, based on a high-quality systematic review of lower-quality, randomized controlled trials). Physicians’ advice to increase physical activity is not effective, even as part of a self-care plan for hypertension (SOR: B, based on 1 randomized trial).
