Social-Cognitive Correlates of Fruit and Vegetable Consumption in Minority and Non-Minority Youth.

摘要

Objective: Inadequate fruit and vegetable (FV) consumption signals a need for identifying predictors and correlates of intake, particularly in diverse adolescents. Design: Participants completed an on-line assessment in early 2010. Setting: Computer classrooms in 4 high schools. Participants: One hundred twenty-two Caucasian and 125 minority (African American and Hispanic) high school students (mean age = 15.3 years, SD = 1.0) with parental consent. Response rate was 89%. Variables Measured: Self-efficacy as measured by confidence in goal setting and decision making about healthful eating; perceived benefits and barriers to eating FVs; healthful eating-related social support; body esteem; and FV intake. Analysis: t tests were used to examine group differences, and binary logistic regression analyses were conducted to explore the predictors of 5-A-Day FV consumption. Results: Thirty-four percent of the non-minority group and 28% of the minority group reported eating 5 or more portions of FVs a day (P = .34). Self-efficacy and perceived benefits predicted consumption in minority participants, whereas barriers and social support were significant predictors in the non-minority group. Conclusions and Implications: These findings suggest different variables predict consumption for minority and non-minority groups and that self-efficacy is an important variable to consider in dietary change programs for minority adolescents
