3. Adherence to non-pharmacological treatment
The efficacy of non-pharmacological therapy, including reduction in dietary salt intake, weight reduction, moderation of alcohol intake and increased physical activity, in lowering blood pressure has been shown by several studies (30,31). In general, among small, well-supervised and motivated groups of patients receiving counselling on moderate salt restriction, most of the patients followed the regimen (30,32,33). There is limited information, however, on adherence to other lifestyle measures intended to lower blood pressure. Most of the problems related to adherence to non-pharmacological treatment are currently assumed to be similar to those related to adherence to antihypertensive drug therapy and this is an area that warrants further investigation.
