Abstrakt:	Background and Aims: The internalization of ideal hypermuscular body and pro-muscularity media's influence have shown their importance in muscle dysmorphia development. The aim of the current study is to have a better understanding of links between specific body checking behaviors and muscle dysmorphia in social network context. Methods: In total, 342 students practicing weightlifting at the university gym in Bordeaux answered to a survey with sociodemographic information and body checking symptoms including taking specific selfies of muscles and muscularity "Muscle Pics" and the MDDI (Muscle Dysmorphic Disorder Inventory). Results: Muscle dysmorphia was prevalent in 18.7% of our population (64 students). We observed that muscle dysmorphia was correlated to "Muscle Pics", "Follow-up", "Message", "Selfie", and gym mirror checking with significant results (P<0.01). Also, « Muscle Pics » were linked to APEDs use, pro-muscularity websites, fitness model comparison and gym mirror checking (P<0.01). For muscle dysmorphia, "Muscle Pics" have strong predictive results (OR=5.10, P=0.000) and (OR=4.08, P=0.000) for adjusted. "Follow up" (OR=4.76, P=0.000) and (OR=3.83, P=0.000) for adjusted, "Muscle Pics Selfie" (OR=11.20, P=0.000) and (OR=11.55, P=0.000) for adjusted, "Muscle Pics Message" (OR=4.49, P=0.001) and (OR=5.78, P=0.001) for adjusted. Conclusion: "Muscle Pics" showed several links with muscle dysmorphia for global score "drive for size", "functional impairment" but not for "appearance intolerance" dimension. Pro-muscularity websites, fitness model comparisons and gym mirror checking are linked to muscle dysmorphia and "Muscle Pics". Future research on "Muscle Pics" will help to provide a better understanding of muscle dysmorphia and its link with pro-muscularity influence websites. (Copyright © 2022 L'Encéphale, Paris.
