Abstract

BACKGROUND: Relatively little is known about the peer influence in health behaviors within university dormitory rooms. Moreover, in China, the problem of unhealthy behaviors among university students has not yet been sufficiently recognized. We thus investigated health behavior peer influence in Peking University dormitories utilizing a randomized cluster-assignment design. STUDY DESIGN: Cross-sectional in-dormitory survey. Study population: Current students from Peking University Health Science Center from April to June, 2009. MEASUREMENT: Self-reported questionnaire on health behaviors: physical activity (including bicycling), dietary intake and tobacco use. RESULTS: Use of bicycle, moderate-intensity exercise, frequency of sweet food and soybean milk intake, frequency of roasted/baked/toasted food intake were behaviors significantly or marginally significantly affected by peer influence. CONCLUSION: Health behavior peer effects exist within dormitory rooms among university students. This could provide guidance on room assignment, or inform intervention programs. Examining these may demand attention from university administrators and policy makers.
