Link between chemerin, central obesity, and parameters of the Metabolic Syndrome: findings from a longitudinal study in obese children participating in a lifestyle intervention

Chemerin has been suggested as a potential link between obesity and associated comorbidities in humans. Therefore, we studied the relationships between chemerin, parameters of fat mass, and Metabolic Syndrome (MetS) in obese children before and after weight reduction. We determined chemerin, bioactive leptin (bioLep), BMI-SDS, waist circumference (WC), body fat based on skinfold measurements and bioimpedance analyses, lipids, transaminases, insulin resistance index HOMA, and blood pressure in 88 obese children participating in a lifestyle intervention at baseline and 1 year later. Furthermore, we determined chemerin concentrations in 23 normal-weight children. Obese children demonstrated significantly (p
