The number of obese children has increased with almost 100 % in a few decades. Deceases like insulin-resistance and type-2 diabetes often comes with overweight and worldwide research to prevent and cure these complications is constantly approaching. This study provides with greater knowledge of what correlations there are between anthropometric measurements, insulin resistance and respiratory quotient.For this study, data from 83 children and teenagers was included. The medical records from their first visit to the pediatric science unit at Uppsala University Hospital was used. To measure basal metabolic rate (BMR), indirect respiratory calorimetrics was used to measure the respiratory ratio at rest and fasting (RQ-BMR), and blood samples were collected to analyze fs-(fasting) insulin. The anthropometric measurements that were taken were waist, waist-height-ratio (WtHR), waist-hip ratio (WHR), waist-hip-height ratio (WHtR), waist circumference (AC), waist circumference-height ratio (ACHR), sagittal abdominal diameter (SAD) and Sagittal abdominal diameter-height ratio (SADHR).Correlations between fs-insulin and WHtR, WCHR, SAD and SADHR was found for the whole group of participators in this study. The strongest correlation was to WHtR for boys and SAD for girls. The RQ-BMR correlated the best with SADHR and ACHR. No correlations between RQ-BMR were found specifically for boys or girls.
