This study examines the fruit and vegetable intake behavior of senior and vocational high school students with reference to their personal backgrounds, psychosocial, and environmental factors. The study sample was composed of 542 students from senior and vocational high schools in Sinying, Tainan, Taiwan. The results showed that nearly 50% of the students reported consuming 3 portions of vegetables daily, and that only 30% of the students consumed 2 portions of fruit daily. The female students, students who reported a higher perceived health status were more likely to intake fruit and vegetables. Self-efficacy and a preference for fruit and vegetables are important psychosocial factors. In addition, role modeling and the availability at home of fruit and vegetables are significant environmental correlates of intake behavior. The personal backgrounds, psychosocial, and environmental variables contained in research model accounted for 51% of the variance in fruit and vegetable intake behavior. These findings demonstrate that a variety of multi-level factors is associated with students’ intake of fruit and vegetables. Therefore, it would be beneficial to incorporate a multi-level approach into health promotion and health education intervention strategies to encourage high school students to consume fruit and vegetables.
