The high prevalence of cardiovascular disease (CVD) in the Hispanic population of the United States, together with low rates of health insurance coverage, suggest a potential cardiovascular health crisis. The objective of Project HEART (Health Education Awareness Research Team) was to promote behavior changes to decrease CVD risk factors in a high-risk Hispanic border population.
Project HEART took place from 2005 through 2008 as a randomized community trial with a community-based participatory research framework using promotores de salud (community health workers). A total of 328 participants with at least 1 CVD risk factor were selected by randomizing 10 US Census tracts in El Paso, Texas, to either the experimental or the control group. The experimental group (n = 192) was assigned to a series of 8 health classes using the Su Corazón, Su Vida curriculum. After 2 months of educational sessions, the group was followed for 2 months. The control group (n = 136) was given basic educational materials at baseline, and no other intervention was used. Main outcomes of interest included changes in health behaviors and clinical measures.
Participants in the experimental group showed more awareness of CVD risk factors, more confidence in the control of these factors, and improved dietary habits (ie, lower salt and cholesterol intake, better weight-control practices) compared with the control group. Total cholesterol was 3% lower in the experimental than in the control participants, and nonhigh-density lipoprotein cholesterol and low-density lipoprotein cholesterol were both 5% lower.
The HEART trial suggests that community health education using promotores de salud is a viable strategy for CVD risk reduction in a Hispanic border community.
美国西班牙裔人群中心血管疾病(CVD)的高发率,加上健康保险覆盖率低,表明存在潜在的心血管健康危机。HEART 项目(健康教育意识研究团队)的目的是促进行为改变,以降低高危西班牙裔边境人群的 CVD 风险因素。
HEART 项目于 2005 年至 2008 年期间进行,采用以社区为基础的参与性研究框架,利用 promotores de salud(社区卫生工作者)进行随机社区试验。从德克萨斯州埃尔帕索的 10 个美国人口普查区中随机选择了 328 名至少有 1 个 CVD 风险因素的参与者,将他们分为实验组(n=192)和对照组(n=136)。实验组接受了一系列 8 节健康课程,使用 Su Corazón, Su Vida 课程。在 2 个月的教育课程结束后,对该组进行了 2 个月的随访。对照组在基线时获得了基本的教育材料,没有使用其他干预措施。主要观察指标包括健康行为和临床指标的变化。
与对照组相比,实验组参与者对 CVD 风险因素的认识提高了,对控制这些因素的信心增强了,饮食习惯也得到了改善(即摄入的盐和胆固醇减少,体重控制措施更好)。实验组参与者的总胆固醇降低了 3%,非高密度脂蛋白胆固醇和低密度脂蛋白胆固醇分别降低了 5%。
HEART 试验表明,使用 promotores de salud 进行社区健康教育是降低西班牙裔边境社区 CVD 风险的可行策略。
