| Summary: | Abstract Background Disordered eating behaviours (DEB) are significant public health challenges among adolescents. DEB are prevalent among Chinese young people and replication epidemiological studies in DEB are needed due to ongoing rapid modernization and socio-economic change. In addition, there has been no prevention or intervention programs for DEB in most of rural areas in China and research in DEB in rural China is limited. More research in DEB in rural China is needed for increased awareness of prevention strategies. The objectives of the study are to examine the prevalence and associated factors of DEB among rural Chinese adolescents. Methods Four hundred and sixty-six students aged 11–18 years old from a middle school in rural China were invited to complete a self-reported questionnaire that included measures on DEB and psychosocial factors. The SCOFF questionnaire was applied to measure DEB (i.e., a score of > = 2 indicates a likely case of DEB). Logistic regression models were applied for data analyses. A p-value <0.05 was regarded as statistically significant. Results There were 389 adolescents (11–18 years) included in this study with the prevalence of DEB being 28.8%. No significant differences were found between male adolescents (30.5%) and female adolescents (27.1%). Independently, perceived overweight (OR = 2.80, 95% CI = 1.05–7.48), negative affect (OR = 1.07, 95% CI = 1.03–1.12), body dissatisfaction (OR = 0.96, 95% CI = 0.93–0.99), and watching TV (OR = 2.40, 95% CI = 1.11–5.18) were significantly (p < 0.05) associated with DEB. Conclusion This study indicates a high prevalence rate of DEB among rural adolescents and associated factors of DEB from a school-based sample. Such findings imply that local public health systems should pay more attention to DEB and design prevention and intervention strategies for DEB.
