Low literacy skills may negatively affect health through misuse of medication, inability to follow medical directions or due to limitations placed on the consumer's ability to access health information. The association between low literacy among adults and cardiovascular disease has not been thoroughly investigated in some ethnic groups. The purpose of this comprehensive study is to describe the results of a nutritional-related cardiovascular health program for limited English proficient adults enrolled in English-as-a-second-language (ESL) classes. Subjects (n = 408), nearly 87% of whom were Latino, were exposed to either nutrition education (intervention group) or stress management (attention-placebo control group) classes designed specifically for ESL classes. Subjects completed physiological measures assessing blood pressure, total and high-density lipoprotein (HDL) cholesterol, waist and hip circumference, and body mass. Self-report surveys were administered to collect students' nutrition-related knowledge, attitudes and behaviors. Data were collected at baseline, 3 month post-test and 6 month follow-up. Analyses showed that differential group change was seen for fat avoidance, nutrition knowledge, HDL and total cholesterol:HDL ratio, but, for the two latter variables, the effect was not maintained at the 6 month follow-up. Both groups showed positive changes in blood pressure, total cholesterol and nutrition-related attitudes. Results showed moderate success of the intervention, but suggest contamination between experimental groups may have occurred.
低读写能力可能会因用药不当、无法遵循医嘱或因消费者获取健康信息的能力受限而对健康产生负面影响。在一些种族群体中，成年人低读写能力与心血管疾病之间的关联尚未得到充分研究。这项综合研究的目的是描述一项针对参加英语作为第二语言（ESL）课程的英语水平有限的成年人的营养相关心血管健康项目的结果。受试者（n = 408），其中近87%为拉丁裔，被分为专门为ESL课程设计的营养教育（干预组）或压力管理（注意力安慰剂对照组）课程。受试者完成了评估血压、总胆固醇和高密度脂蛋白（HDL）胆固醇、腰围和臀围以及体重的生理指标测量。进行了自我报告调查以收集学生与营养相关的知识、态度和行为。在基线、测试后3个月和6个月随访时收集数据。分析表明，在避免脂肪摄入、营养知识、HDL以及总胆固醇与HDL比值方面，两组出现了不同的变化，但对于后两个变量，在6个月随访时效果未持续。两组在血压、总胆固醇和与营养相关的态度方面均呈现出积极变化。结果显示干预取得了一定成功，但表明实验组之间可能发生了相互影响。
