Obesity and overweight in childhood leads to insulin resistance, elevated blood lipids and cardiovascular effects. Obesity is caused by positive energy intake, poor exercise habits, environmental factors, food habits and stress etc. It is also known that hormones influence the incidence of obesity. It has been found that individuals with overweight and obesity has elevated glucagon levels in the bloodstream Purpose: This work aims to investigate whether there is a difference in glucagon concentration between the sexes at ages 10-18 years with obesity, and if there is an association between glucagon concentration and weight, FM and FFM. Materials and Methods: In this study, obesity is determined by BIA and the caliper in combination as three compartment model. Blood samples were taken by venipuncture and glucagon were analyzed in fasting plasma. Results: BIA and the caliper together had a significant correlation with body composition. Blood glucagon was found to be high in obese children. Conclusion: Glucagon concentration in obese children correlates with weight and FM. However, further investigation is needed regard to how glucagon interact with weight, FM and FFM
