Patients And Methods: We studied 2,519 randomly selected patients, from 11 hospitals, 2 endocrine and one general public care clinics from 10 cities. Overweight was defined as body-mass index (BMI) > 25 and obesity as BMI > 30 kg/m2.

[Prevalence of immunologic markers (Anti-GAD and Anti-IA2) in first-degree relatives of patients with type I diabetes in the greater area of São Paulo].

Background: Increasingly accurate prediction of Type I Diabetes Mellitus (DMI), based on analysis of autoantibody markers, has become possible in first-degree relatives of patients with diabetes (PDMI). These markers indicate autoimmune process against pancreatic islet beta-cells. Anti-GAD and anti-IA2 are considered predictive of DMI, whose prevalences are considerably variable in different populations studied.
