    Abstract:
    AIM: The aim of this study was to assess the vaspin and adiponectin concentrations on markers of insulin sensitivity and obesity in pubertal obese children and adolescents. MATERIAL AND METHODS: Plasma vaspin and adiponectin level and its relationships with body mass index standard deviation score (BMI-SDS), insulin sensitivity and lipids were analyzed in 33 pubertal obese children (19 girls and 14 boys) and 36 healthy control children (18 girls and 18 boys) aged 11-16 years. Insulin resistance was evaluated by homeostasis model assessment (HOMA-IR) and fasting glucose-to-insulin ratio (FGIR). Plasma vaspin and adiponectin concentrations were determined with radioimmunoassay. RESULTS: Mean vaspin levels were found significantly higher and inversely, adiponectin levels were found significantly lower in obese pubertal group than control subjects. Vaspin levels were positively correlated with BMI-SDS, triglycerides, fasting insulin and HOMA-IR and negatively correlated with adiponectin levels and FGIR. Adiponectin levels were positively correlated with high density lipoprotein-chloesterol, FGIR and negatively correlated with vaspin, BMI-SDS, fasting insulin and HOMA-IR. CONCLUSION: We found higher vaspin and lower adiponectin levels in obese children and these adipokines were significantly correlated with insulin sensitivity indices in this age.
