Hypertension (HTN) is a leading cause of cardiovascular and cerebrovascular diseases. Lifestyle modification may be the preferential approach to prevent and control HTN. The purpose of this study was to evaluate the effects of a community intervention program, which focused on improving the HTN knowledge, diets and lifestyles in a rural Chinese area. The study was carried out in a rural area of the Hubei Province from May 2003 to April 2006. A total of 1632 participants were recruited. Of the participants, 826 from the town of Xiaoxita and 806 from the town of Fenxiang were assigned to the intervention group (group I) and to the control group (group C), respectively. Group I participants underwent an intervention that included HTN education and dietary and lifestyle guidance. Group C participants were not subjected to an intervention. The outcome measures included HTN knowledge, dietary and lifestyle behaviors, and prevalence, awareness, treatment and control rates of HTN. Along with the changes in HTN education (P<0.05), the participants in group I exhibited a significantly greater improvement in dietary habits and lifestyle behaviors, including reducing salty food intake (13.6%), fat intake (22.9%) and alcohol consumption (9.6%), after 3 years in comparison with those in group C (21.7, 31.9 and 18%, respectively). The prevalence of HTN was significantly lower in group I (22.5%) than in group C (36%) after the intervention strategies. The study showed that the implementation of a community intervention program involving HTN education and lifestyle modifications for rural residents is a powerful approach to reduce HTN prevalence and improve long-term health outcomes.
