Diabetic nephropathy is a major cause of morbidity and mortality among young adults with type 1 diabetes. Many risk factors may influence its onset or progression.The aim of the present study was to assess the microalbuminuria, in type 1 DM patients at DEMPU, the screening protocol and its association with potential risk factors. We studied 284 patients with T1DM; mean ages were 17.1± 5.4 yrs and mean duration of diabetes of 10.1± 4.8 yrs. They were fully evaluated clinically and reviewing the records.Microalbuminuria was present in 14.8 % of patients with type 1 DM after a mean follow up of 10 yrs at DEMPU. Microalbuminuria was associated with female sex, longer duration of diabetes, hypertension, poor glycemic control, short stature and limited joint mobility but not significantly associated with dyslipidemia and age of onset of diabetes
