Development of a protocol to assess dietary intake among Hispanics who have low literacy skills in English.

Hispanic adults who had low literacy in English (n = 14.3) and who attended community college English-as-a-Second-Language (ESL) classes, completed 24-hour dietary recalls using version 2.5 of the computerized Minnesota Nutrition Data System (NDS), which included many Hispanic foods. The purposes of our study were to assess the appropriateness of NDS for a Hispanic group who had low literacy in English, to describe the development and implementation of training procedures for NDS interviewers, and to discuss the special problems that occurred using the enhanced version of NDS. Further, nutrient, intakes for the study population, as calculated using NDS, were compared with nutrient estimates from the Hispanic Health and Nutrition Examination Survey (HHANES). Results suggest that version 2.5 of NDS is a useful tool for collecting dietary information for Hispanics who have low literacy in English. Challenges encountered during data collection for this study could be categorized into three types: regional differences in foods, food preparation differences, and lack of appropriate options in NDS for preparation methods. Generally, the study group and HHANES participants had similar intakes, although the study group tended to have a more healthful nutrition profile. Overall, findings indicate that NDS is a promising assessment tool for nutrition practitioners who work with Hispanics who have low literacy in English. Continued improvements to the NDS system can correct its shortcomings related to regional/ cultural food differences.
