The present study was designed to explore the possible mechanism of obesity associated metabolic syndrome. 150 subjects (120 men and 30 women) in the age-group of 17 - 26 years were studied. Body Mass Index and Waist-to-Hip Ratio were taken as a measure of generalized obesity and abdominal adiposity. The serum concentration of glucose-6-phosphate dehydrogenase increased with increasing levels of Body Mass Index and was found to be significant in obese subjects (Body Mass Index ≥ 30.0 kg/m2) and more so in the obese subjects with abdominal adiposity (p = 0.002) as compared to normal-weight subjects. Karl Pearson coefficient of correlation revealed a significant positive correlation of glucose-6-phosphate dehydrogenase with Body Mass Index (r = 0.499; p < 0.001) and malondialdehyde (a biomarker of oxidative stress) (r = 0.736; p < 0.001) but inverse correlation with adiponectin (r = -0.524; p < 0.001). Thus, we conclude that increased expression of glucose-6-phosphate dehydrogenase in obese subjects (more if it is associated with abdominal adiposity) might mediate the onset of obesity associated metabolic disorders by increasing oxidative stress.
