Abstract
BACKGROUND: Measurement of sagittal abdominal diameter using a revalidated caliper is simple, inexpensive, non-invasive method. It strongly correlates with insulin resistance and can be used as a surrogate marker to predict risk for Type II Diabetes Mellitus. AIM: To assess visceral abdominal fat by measuring sagittal abdominal diameter using sliding calipers and to predict insulin resistance in obese or overweight adolescent children. STUDY DESIGN: Explorative study for Paediatric age group among over weight and obese children aged 10-18 years in urban population in a Tertiary Care Centre. MATERIALS AND METHODS: Paediatric population satisfying ADA guidelines for diagnosis of prediabetes were included in the study. Anthropometric measurements with SAD were recorded. Blood was collected to investigate for prediabetes and insulin resistance using HOMA-IR. RESULTS: Out of 924 subjects who gave assent to participate in study 108 fulfilled ADA criteria. 33 subjects who didn't come for the follow up were excluded. Out of 75 subjects 12 were detected to have insulin resistance (16%) and 63 were normal (84%). Pearson's partial correlation of HOMA-IR and OGTT with SAD has demonstrated it to be better correlation with Insulin Resistance (IR) than other anthropometric measurements. Fasting Glucose correlated better with Waist Hip Circumference. CONCLUSION: Insulin Resistance was diagnosed in 16% of the population and these had high levels of insulin resistance. SAD in relation to glucose metabolism, had a better correlation with OGTT followed by HOMA-IR and fasting Insulin. SAD with anthropometric measurements had better correlation all the parameters other than Waist Circumference, which had negative correlation. SAD can be used in evaluation of obese or overweight children for evaluation.
