The indirect role of orthorexia nervosa and eating attitudes in the association between perfectionism and muscle dysmorphic disorder in Lebanese male University students – results of a pilot study

Abstract

Abstract Background The literature highly concentrates on disorders related to body image among women but only minimally when it comes to the male population; hence, in order to provide general practitioners, and primary care physicians in general, and psychiatrists in particular, with additional information concerning muscle dysmorphia among male university students in Lebanon, this study seemed essential, and was therefore conducted to (1) identify the prevalence of MDD, and (2) evaluate the indirect effect of eating attitudes in general and orthorexia nervosa in particular, in the association between perfectionism and muscle dysmorphic disorder (MDD) among a sample of male university students. Methods In this cross-sectional study conducted between September 2021 and May 2022, 396 male university students from multiple universities in Lebanon filled the online Arabic questionnaire. Results The results showed that 26 (6.6%) of the participants had MDD. Orthorexia nervosa and eating attitudes mediated the association between perfectionism and MDD; higher perfectionism was significantly associated with higher ON and more inappropriate eating; higher ON and more inappropriate eating were significantly associated with higher MDD, whereas perfectionism had a significant total direct effect on MDD. The high prevalence of MDD among male university students in Lebanon implies further investigation on the national level in the country. Conclusion Awareness campaigns among the university students could be adopted at the national level to increase the level of knowledge on the concepts of obsessive self-destructive perfectionism, orthorexia nervosa and muscle dysmorphia.
