Risk factors of impaired glucose tolerance in obese children aged 12-15 years old

Methods A cross sectional study was performed in 12-15 years old obese children from 10 Junior High Schools in Jakarta. History of T2DM in the family was determined by anamnesis with the parent. Clinical sign of acanthosis nigricans (AN) was fixed by physical finding. The intensity of physical activity was measured using the activity criteria according to World Health Organization. The diagnosis of IGT was determined using an oral glucose tolerance test (OGTT) according to American Diabetes Association (ADA) criteria in 2006. Proportion of AN, history of T2DM in the family, physical activity, and IGT were measured. Fisher test was used to analyse the risk of IGT based on BMI; Mann-Whitney test was based on AN, physical activity, and history of T2DM. Logistic regresion analysis was done based on the clinical judgement.
