Prevalence of Body Dysmorphic Disorder (BDD) among the Lebanese University students: associated risk factors and repercussion on mental health.

Introduction: Body Dysmorphic Disorder (BDD) is a psychological illness characterized by persistent and intrusive preoccupation with an imagined or slight defect in appearance. This study aimed to determine the prevalence of BDD and investigate its association with mental health status (depression and anxiety), religiosity, eating disorder risk, and self-esteem among Lebanese University students. Methods: A cross-sectional study was conducted in March 2020, involving students from the Lebanese University. Data were collected using the dysmorphic concern questionnaire (DCQ), Rosenberg self-esteem scale (RSE), religiosity scale, patient health questionnaire (PHQ-9), generalized anxiety disorder assessment (GAD-7), Eating Attitude test-26 scale (EAT-26). Results: A total of 6,448 participants were enrolled in our study. The overall prevalence of BDD among university students was (6.4%).Our results showed that Lebanese students with BDD were more likely to have anxiety ORadj 1.3 (95% CI: 1.2-1.7) p-value 0.001, depression ORadj 1.2 (95% CI: 1.15-1.5) p-value 0.007, and eating disorder (Bulimia & Food preoccupation ORadj 1.06 (95% CI: 1.03-1.2) p-value 0.0, and oral control ORadj 1.09 (95% CI: 1.05-1.1) p-value < 0.001) compared to those with no BDD. We also found that students with BDD had Lower Self-esteem ORadj 0.88 (95% CI: 0.78-0.9) p-value < 0.001), and less likely to be religious ORadj 0.88 (95% CI: 0.82-0.9) p-value 0.02) compared to those with no BDD. Conclusions: This pioneering study sheds light on the prevalence of BDD among Lebanese university students and its associated factors. Our findings underscore the importance of early detection of BDD during adolescence and young adulthood, necessitating timely psychological intervention to prevent chronicity and complications.
