AbstractAlthough adiponectin is correlated inversely with obesity, some obese adults without metabolic complications of obesity have paradoxically high adiponectin. Therefore, we assessed adiponectin risk factor relations in 133 obese 16-year-old school girls from a cohort of 448, focusing on paradoxically high adiponectin-risk in obesity and the healthy obese phenotype. Median adiponectin (11.9 mg/L) in nonobese girls (body mass index [BMI] < 24.6 kg/m²) was selected as a cutpoint to identify high adiponectin in obese girls. Of 90 black and 43 white obese girls (BMI ≥ 24.6), 25 black (28%) and 13 white (30%) girls had paradoxically high adiponectin (>11.9). The 38 obese girls with adiponectin >11.9 versus the 95 obese girls with adiponectin ≤11.9 had higher median high-density lipoprotein (HDL) cholesterol (54 vs 46 mg/dL, P = 0.0007) and apolipoprotein A1 (ApoA1) (181 vs 164 mg/dL, P = 0.011) and had lower insulin (14 vs 20 uU/mL, P = 0.0006). In the 133 obese girls, through stepwise regression, the adiponectin category (>11.9, ≤ 11.9 mg/L) was a significant independent positive determinant of HDL cholesterol (partial r² = 8.4%, P = 0.001), ApoA1 (partial r² = 4.1%, P = 0.025), and it was associated inversely with fasting serum insulin (partial r² = 5.4%, P = 0.0074). By stepwise logistic regression in the 133 obese girls, the adiponectin category (high vs low) was a significant inverse explanatory variable for metabolic syndrome (odds ratio 0.20, 95% confidence intervals 0.04-0.95, P = 0.043). We conclude that paradoxically high adiponectin is associated with the healthy obese phenotype in obese adolescent black and white girls.Copyright © 2010 Mosby, Inc. All rights reserved.
