To investigate the impact of social cognitive determinants on healthy eating behaviors among adolescents, with a specific focus on gender differences.Cross-sectional analysis of survey data.Bangkok, Thailand.A total of 1,200 undergraduates from public and private universities.Dependent variable: healthy eating behaviors measured by the total score of 11 items adapted from the Australian Dietary Guideline Index. Independent variables: self-efficacy, intentions, outcome expectations, perceived benefits, perceived barriers, situations, social support from parents and guardians, and social support from peers (measured by 54 Likert-type items).Multiple linear regressions (α and P < .01).Self-efficacy, intentions, perceived barriers, and situations had statistically significant relationships with healthy eating behaviors (ß = .17, .16, −.15, and .19, respectively). The predictor variables explained 18.1% of variance. Healthy eating in male adolescents was best predicted by perceived barriers, whereas that in female adolescents was best predicted by situations.These results indicate that relevant agencies should deliver gender-specific approaches to promote healthy eating in adolescents. The findings demonstrate the need for further studies to explore a broader range of factors influencing adolescent eating behaviors.
