Association between eating behavior, anthropometric and biochemical measurements, and peptide YY (PYY) hormone levels in obese adolescents in outpatient care

Association between eating behavior, anthropometric and biochemical measurements, and peptide YY... AbstractObjectiveTo evaluate the eating behavior of obese adolescents and its association with biochemical, anthropometric and peptide YY (PYY) measures.MethodsFifty-one obese adolescents received counseling for weight management at 12 monthly appointments. Fasting serum PYY levels, total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglycerides (TG), low density lipoprotein cholesterol (LDL-C), insulin and glucose levels, waist circumference (WC) and results from the Three-Factor Eating Questionnaire (TFEQ-21) were assessed.ResultsOver one year there was a significant increase in PYY levels (p = 0.026), reduction in TC (p = 0.003), TG (p = 0.022), BMI (p = 0.002), BMI z-score (p < 0.001) and WC (p = 0.003). During this period there was a decrease in the uncontrolled eating score (UE), illustrating that adolescents displayed more self-control (p = 0.008) at the end of the study; however, this result was independent of BMI and BMI z-score (p = 0.407). The reduction in UE was associated with a significant improvement in insulin levels (rs = 0.326; p = 0.020). The reduction in UE was also associated with lower levels of blood glucose (r = 0.332; p = 0.017), and the increase of cognitive restriction, with the reduction of insulin insulin (rs = −0.294; p = 0.036) and TG (r = −0.368; p = 0.008) and an increase in Cognitive Restraint.ConclusionsOur results show that after a year of monitoring weight loss, adolescents had more controlled eating behaviors, increased PYY levels, and reduced weights. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Pediatric Endocrinology and Metabolism de Gruyter
