Objective To investigate the current situation of disordered eating behaviors in adolescents with type 1 diabetes mellitus，and to analyze the influencing factors of disordered eating behaviors. Methods A total of 187 adolescents with type 1 diabetes mellitus were recruited from a tertiary hospital during follow-up by the convenient sampling method from December 2021 to September 2022. The General Information Questionnaire，the Diabetes Eating Problem Survey-Revised，the Problem Areas in Diabetes Scale-5，the Diabetes Strengths and Resilience Measure for Adolescents，and the Dual-Mode of Self-Control Scale were used to explore the current status of disordered eating behaviors in adolescents with type 1 diabetes. We adopted the multiple linear regression model to analyze the influencing factors of disordered eating behaviors. Results 174 participants completed the questionnaires. The scores of disordered eating behaviors were（21.25±10.93） points. The incidence of disordered eating behaviors was 54.60%. The multiple linear regression analysis showed that the influencing factors of disordered eating behaviors involved gender，BMI，mental distress，resilience，and self-control. Conclusion High disordered eating behaviors exist in adolescents with type 1 diabetes. Medical practitioners should regularly evaluate patients’ disordered eating behaviors，especially female，obese or overweight patients. Through correcting the patients’ problematic body image cognition，and enhancing their confidence in disease control，medical staff could help them cope with stress positively，reduce negative emotional experiences，and further decrease the occurrence of disordered eating behaviors.

Objectives To explore the level of resilience among adolescents with Type 1 diabetes and its association with glycemic control,diabetes distress,and quality of life. Methods A total of 360 adolescents with Type 1 diabetes were recruited from the outpatient and inpatient in Endocrinology departments of 2 public hospitals in Nanjing by convenience sampling method. The data were collected by the Diabetes Strengths and Resilience Measure for Adolescents,the Problem Areas in Diabetes Scale-5,the Short Form of the Chinese version Diabetes Quality of Life for Youth Scale,and the Self-Designed General Information Questionnaire. Results The resilience of adolescents with Type 1 diabetes was 40.18±9.27,which was above the medium level. Resilience was negatively correlated with glycosylated hemoglobin value（r=-0.373,P<0.001） and diabetes distress（r=-0.336,P<0.001）,while it was positively correlated with quality of life（r=0.431,P<0.001）. Hierarchical regression analysis showed that resilience independently explained 10.0% of the variation in glycemic control,7.8% of diabetes distress,and 17.7% of the quality of life,after controlling for demographic and disease variables. Conclusions Interventions that target patients’ resilience may improve their glycemic control,mental health,and quality of life,which should arouse the attention of medical workers.
