The objectives of this study were: 1) to evaluate the acceptance, effectiveness, and sustainability of a promotora (community health worker) pilot program to improve hypertension control among medically underserved Mexican Americans of the El Paso, Texas area, and 2) to demonstrate improvements in clinical measures of blood pressure, BMI and waist circumference, self-reported behaviors and changes in attitudes and beliefs about blood pressure among Mexican American hypertensives. Participants were eligible if they had been diagnosed with hypertension and if they were willing to be randomized as either participants in the intervention or as controls. A total of 58 participants enrolled in the intervention group and 40 participants served as controls. This was a 9-week promotora intervention. Health behavior constructs and clinical data were measured pre-post intervention. Perceived benefits, and two heart-healthy behaviors (salt and sodium, and cholesterol and fat) were shown to be statistically significantly different between the intervention and control groups.
1）评估一项由社区健康工作者（promotora）开展的试点项目的接受度、有效性和可持续性，该项目旨在改善德克萨斯州埃尔帕索地区医疗服务不足的墨西哥裔美国人的高血压控制情况；2）证明墨西哥裔高血压患者在血压、体重指数（BMI）和腰围等临床指标、自我报告行为以及对血压的态度和信念方面有所改善。参与者若被诊断患有高血压且愿意被随机分配为干预组参与者或对照组，则符合条件。共有58名参与者纳入干预组，40名参与者作为对照组。这是一项为期9周的社区健康工作者干预项目。在干预前后测量健康行为构成因素和临床数据。结果显示，干预组和对照组在感知益处以及两种有益心脏健康的行为（盐与钠、胆固醇与脂肪）方面存在统计学显著差异。
