Sex hormone-binding globulin levels and cardiovascular risk factors in morbidly obese subjects before and after weight reduction induced by diet or malabsorptive surgery.
One of the main goals of weight reduction in morbidly obese subjects is its benefit on coronary heart disease ( CHD ) risk . A cross-sectional study was design ed to r and omly assign 79 morbidly obese subjects ( 27 men and 52 women ; age : 30 - 45 years ) either to a diet protocol ( 20 kcal per kg fat-free mass ( FFM ) ; 55 % carbohydrates , 30 % fat , and 15 % proteins ) or to malabsorptive surgery ( biliopancreatic diversion ) .  Fatness parameters , measured by dual-energy X-ray absorptiometry , lipid profile , insulin , leptin , sex steroid hormones and sex hormone-binding globulin ( SHBG ) levels were compared at baseline and 1 year after the beginning of the study . The data showed that plasma SHBG levels , but not testosterone levels , correlated negatively to fasting insulin levels and positively to HDL-cholesterol in both men and women . Total leptin levels were significantly lower ( P<0.0001 ) in post-BPD subjects of both sexes compared to dietary treated obese subjects . The logarithm of plasma leptin correlated significantly and positively with insulin but negatively with SHBG.A step-down regression analysis showed that FFM and SHBG , but not insulin levels , were the most powerful independent variables for predicting HDL-cholesterol levels in morbidly obese patients . The negative relationship between SHBG levels and CHD risk appears to be mediated by a concomitant variation in body fatness . Finally , in obese patients , SHBG levels seem to be an indicator of total adiposity rather than an index of an altered insulin/glucose homeostasis
Furthermore , except for certain cardiovascular indicators , bariatric surgery was superior to conventional arms in terms of metabolic secondary parameters ( P < 0.05 ) .
