The aim of this study was to evaluate the association between serum adiponectin concentrations and anthropometric indices and lipid profiles among Iranian women with different grades of obesity. Materials and Methods: In this analytical de-scriptive study of 157 non-diabetic women (33 normal weight, BMI&lt; 25 kg/m2 and 124 over-weight and obese, BMI≥ 25kg/m2), serum adipo-nectin and leptin levels were measured using an enzyme-linked immunoassay. Fasting glucose and lipid profile levels determined by the glu-cose oxidize and enzymatic methods, respective-ly. Results: Mean serum adiponectin concentra-tion significantly decreased with obesity (p&lt;0.05). Although adiponectin showed a significant neg-ative correlation with BMI (r=-0.321), it was cor-related with serum leptin (r=-0.139), glucose (r=0.259), LDL-C (r=-0.125), TGs (r=-0.210) levels, TSF (r=-0.145), WHR (r=-0.159), and positively with serum HDL-C concentration (r=0.218) in all subjects (p&lt;0.05). Results of multiple regression analyses showed that adiponectin as a dependent variable had a significant correlation with BMI (&#223;=-0.605, P=0.017), waist circumference (&#223;=0.624, p=0.029), WHR (&#223;=-0.251, p=0.048), frame (&#223;=0.260, p=0.018), TC/HDL-C ratio ( &#223;=-0.1.309, p=0.040) and LDL/HDL ratio (&#223;=-1.343, p=0.007) and changes in waist size had a significant effect on serum adiponectin levels. Conclusion: Our results suggested that adiponectin had an inverse correlation with adiposity indices and un-favorable lipid profiles, and that variation of waist circumference mostly affected Iranian women.Adiponectin, BMI, Obese, Lipid profile, Anthropometric indicesAdiponectin in obese subjectsZarghami N.10/24/2009 12:00:00 AM1/3/2010 12:00:00 AMZarghamin@yahoo.com37170178http://www.ijem.org/Default.aspx
