Native American childhood obesity prevention interventions: a systematic review

Native American populations are at higher risk for becoming obese and suffering from obesity-related illness compared with other populations. Concurrently, prevention methods have not been successful with this group, especially intervention attempts aimed at children, which have been few and ineffective. The purpose of this systematic review was to evaluate the effectiveness and methodologies of childhood obesity prevention interventions targeting Native American youth, and to make recommendations to future researchers and practitioners. Seven databases (Medline, Academic Search Premier, CINAHL, ERIC, Health Source Nursing, PsychINFO, and Sport Discus) were utilized to retrieve articles, using four sets of keywords; 1. Children AND Obesity AND Native American AND Program; 2. Children AND Obesity AND Native American AND Intervention; 3. Children AND Obesity AND Indian AND Program; and 4. Children AND Obesity AND Indian AND Intervention. Overall, six articles were found and evaluated for salient findings and key methodological issues such as use of theory, intervention duration, research design, outcome measures, process evaluation, and validated measures. Results indicated that theory was seldom used in planning the interventions, process evaluations were used some of the time, and half of the interventions were smaller pilot studies. This review suggests that there have been few interventions targeting obesity prevention among Native American youth over the past decade. Recommendations for enhancing such programs are discussed.
