Results of language for health: cardiovascular disease nutrition education for Latino English-as-a-second-language students

Abstract

This report presents the final evaluation of Language for Health, part of a federally funded initiative to develop heart disease prevention interventions for low-literate populations. Language for Health specifically intervened with recent immigrants enrolled in English-as-a-second-language classes, incorporating nutritional behavior change materials into English-language curricula. Latino participants (n = 732) were exposed to either nutrition education or stress management classes (attention-placebo group) designed specifically for low-English-literate adults. Participants completed physiological measures assessing blood pressure, total and high-density lipoprotein (HDL) cholesterol, waist and hip circumference, and weight. Self-report surveys were administered to collect students' nutrition-related knowledge, attitudes, self-reported fat avoidance behaviors, and demographic information. Data were collected at baseline, 3-month posttest, and 6-month follow-up. Results indicated long-term effects of the intervention on nutrition knowledge and fat avoidance, yet only short-term effects on total cholesterol:HDL ratio and systolic blood pressure.
