Abstract

Background: Recently, the cut-off point for normal fasting glucose (FG) level, was decreased to 100 mg/dl. Aim: To determine the frequency of abnormal carbohydrate abnormalities in children with obesity and evaluate if the fasting glucose level is a useful tool for the screening of glucose intolerance (GI). Patients and methods: Children and adolescents, referred for evaluation of obesity were evaluated with an oral glucose tolerance test (OGTT) and FG. The sensitivity of FG for detection of GI, using the 100 and 110 mg/dl cut-off point, was evaluated. Results: We studied 186 patients (125 females) aged 12.1 (range: 5.4-19.3) years with a body mass index (BMI) of 29.9 (18.3-44.6) kg/mt
