Abstract : The aim of this study was to describe the sociodemographic, socioeconomic, anthropometric and biochemical characteristics of children and adolescents with T1D in the pediatric unit of the El-Jadida provincial hospital. The study involved a sample of 378 diabetic children and adolescents aged between 2 and 15 years. A structured questionnaire was used to collect information on sociodemographic status and disease characteristics. Weight, height, waist circumference and skinfold sum were measured, and WHtR and BMI were calculated. Biochemical measurements were performed. The main results of this research showed that 51.9% of respondents were female and 62.4% were from urban areas. The average age of the study population was 9.01 ± 4.18 years, with 45.2% aged between 11 and 15 years. Only 23.3% of the children achieved an optimal GC level (HbA1c<7.5%). It should therefore be emphasized that optimal management of diabetes requires good knowledge of the disease and practical advice, through patient education.
