- W2952181508 abstract "Abstract Objectives To identify sociodemographic and psychosocial factors associated with diet quality among Native American adults. Methods Cross-sectional data from the baseline assessment of a cluster-randomized obesity prevention trial (OPREVENT2) of 580 Native American adults from six tribal communities in the Midwest and Southwest. The Healthy Eating Index (HEI-2015) was used to define diet quality, calculated from a semi-quantitative food frequency questionnaire (modified Block FFQ). Sociodemographic (age, sex, education, food assistance) and psychosocial factors (nutrition knowledge, self-efficacy, health eating intentions) were assessed via questionnaires administered by trained data collectors. One-way ANOVA, linear regression models, and two-tailed t-tests assessed compared mean total HEI scores among sociodemographic categories. Bivariate linear regression models assessed the relation between psychosocial factors and diet quality. Results Overall diet quality was low, with a mean HEI-2015 score of 49 (SD + 8), which is 10 points lower than in the general U.S. population. The HEI scores of smokers were an average of 3 points lower than those of non-smokers (P < 0.001), and females had better diet quality (2.2 points higher) than males (P < 0.01). Those receiving commodity food assistance had mean total HEI scores 2.7 points lower than those who did not receive commodities (P < 0.005), and no other source of food assistance was associated with HEI. Self-efficacy (b = 0.66; P < 0.001) and healthy eating intentions (b = 0.72; P < 0.001) were positively associated with mean HEI. Conclusions While nutrition knowledge has been a key focus of many dietary interventions, it does not appear to be associated with better diet quality among Native Americans. This finding suggests that it is necessary to focus interventions on factors other than nutrition knowledge that may impact food choice. Because higher self-efficacy and healthy eating intentions were associated with better diet quality, a social-cognitive approach to dietary interventions may be more effective in Native American populations. Funding Sources OPREVENT2 is funded by a grant from the National Heart, Lung, and Blood Institute." @default.
