    Abstract
    Purpose: The purpose of this article is to examine the effect of a school-based nutrition intervention using an ecological approach to improve adolescents’ nutrition-related knowledge, attitudes and behaviour in rural China. Methods: A cluster-randomised intervention trial design was employed. Two middle schools were randomly selected and assigned to the school that was conducting a holistic school-based intervention using health-promoting school (HPS) framework, ‘HPS School’, or to the ‘Control School’ in Mi Yun County, Beijing. From each school we randomly selected 65 seventh-grade students to participate in the study. ...

    Purpose: The purpose of this article is to examine the effect of a school-based nutrition intervention using an ecological approach to improve adolescents’ nutrition-related knowledge, attitudes and behaviour in rural China. Methods: A cluster-randomised intervention trial design was employed. Two middle schools were randomly selected and assigned to the school that was conducting a holistic school-based intervention using health-promoting school (HPS) framework, ‘HPS School’, or to the ‘Control School’ in Mi Yun County, Beijing. From each school we randomly selected 65 seventh-grade students to participate in the study. Their nutrition-related knowledge, attitudes and behaviour were measured by pre- and post-intervention surveys with the same instrument. The nutrition intervention lasted for six months. Results: Adolescents in the intervention school were more likely to know the nutrition knowledge items, with an odds ratio (OR) ranging from 1.86 (95% confidence interval (CI): 1.11–3.09) to 6.34 (95% CI: 3.83–10.47); more likely to think nutrition is very important to health, developing healthy dietary habits is very important, and that expired foods should be thrown away, with ORs of 3.03 (95% CI: 1.60–5.76), 2.76 (95% CI: 1.66–4.59) and 2.35 (95% CI: 1.33–4.17) respectively, and more likely to consume no soft drinks, desserts or fried food, and to eat vegetables every day of the last week, with ORs of 1.99 (95% CI: 1.31–3.04), 3.96 (95% CI: 2.43–6.46), 3.63 (95% CI: 2.26–5.85), and 2.51 (95% CI: 1.41–4.48) respectively, as compared with those in the control school after interventions. Conclusions: Our intervention using the HPS framework, an ecological approach, was an appropriate model to promote nutrition among adolescents in rural China and its use should be advocated in future school-based nutrition promotion programmes for adolescents.
