Relationship between bullying and type 1 diabetes mellitus in children and adolescents: a systematic review

Objective: To carry out a systematic review on the relationship of bullying with type 1 diabetes in children and adolescents. Methods: Systematic review, according to the PRISMA methodology, in which the databases PubMed, Web of Science, Scopus, Thomson Reuters, Eighteenth Century Collections Online, Begell House Digital Library, LILACS, and SciELO were searched using the terms "bullied", "aggression", "peer victimization", "victimization", "school violence", "diabetes mellitus", "type 1 diabetes mellitus", "autoimmune diabetes", "children" and "adolescents." The authors included original studies, involving bullying associated with type 1 diabetes, with children and adolescents, without language restriction and publication period, with texts available in full. Results: Of the 32 articles found, four studies met the selection criteria. Of these studies 85.7% identified occurrence of victimization in diabetics or found a higher frequency in diabetic children and adolescents when compared with young people with other chronic conditions or with healthy peers. Association between bullying and worse gtycemic control was observed in two studies, and all the studies mention the fact that type 1 diabetes is a limiting factor for socialization related to diabetes, with less social support and difficulties for the management of the disease in public environments, such as school. The type of bullying suffered varied, including physical, verbal, social, psychological, and sexual. Conclusion: Most of the studies showed an association between bullying and type 1 diabetes when compared to individuals with no such condition. Knowledge of this association has become essential for the follow-up of these patients and the implementation of preventive programs. (C) 2018 Sociedade Brasileira de Pediatria.
