Abstract
To determine the frequency of metabolic syndrome (MS) and insulin resistance (IR) in first-degree relatives of type 1 diabetic patients (FDR1) and to study the relationship between these two disorders and some clinical, biochemical and immunological characteristics. We studied 289 persons, of which 193 were children/adolescents and 96 were adults. Weight, height, waist and hip circumference, blood pressure, blood glucose, insulin, cholesterol, triglycerides, high-density lipoprotein-cholesterol, glutamic acid decarboxylase autoantibodies (GADA) and tyrosine phosphatase autoantibodies were determined. IR was assessed through the insulin resistance index (HOMA-IR). The criteria of the World Health Organization for adults and the Cuban consensus for children and adolescents were used to define MS. The prevalence of MS in child and adolescent FDR1 was 5.7% (11/193) while IR was found in 24.9% (48/193). For adult FDR1, the frequency of MS was 6.2% (6/96) and that of IR was 14.6% (14/96). Interestingly, an association was found between IR and MS in adults but not in children and adolescents. IR was more frequent in children and adolescents than in adults (p<0.05). The presence of GADA was associated with IR but not with MS (p<0.05). ...Continue Reading
