Eating Disorder Risk, Sleep Status, and Anthropometric Indices among Teenage Female Students

Introduction: Eating disorder (ED) is characterized by a persistent disturbance of eating or eating-related behavior that results in significantly impaired physical health and psychosocial functioning. It has been revealed that ED patients had significantly lower sleep efficiency. The purpose of this study was to evaluate the prevalence of ED risk and its possible relationship with body mass index (BMI) and sleep status among primary high school girls in Zanjan, Iran. Methods: Teenage girl students (12–15 years old, n = 370) participated in a descriptive study with a cross-sectional design and completed the Eating Attitude Test-26 and Pittsburgh Sleep Quality Index questionnaires. Cluster random sampling method was applied. Disordered eating attitudes, recent sleep quality, and anthropometric measures were extracted. Statistical analysis was performed using SPSS software version 24.0. Results: A statistically significant relationship was found between sleep quality score and ED risk in this study (P 0.001). No significant relationship was found between waist circumference, weight, and BMI with the risk of ED (P 0.05). Conclusion: The high prevalence of ED risk was found among school students in this study. Further studies are needed to evaluate the correlation between ED risks and sleep quality as well as BMI.
