Abstract
Context: Low testosterone (T) has been associated with incident metabolic syndrome (MetS), but it remains unclear if this association is independent of sex hormone binding globulin (SHBG). Estradiol (E2) may also be associated with MetS, but few studies have investigated this. Objective: To study the association between baseline sex steroids and the development of incident MetS and to investigate the influence of SHBG, BMI and insulin resistance on this risk. Methods: 3369 community-dwelling men aged 40-79 years were recruited for participation in EMAS. MetS was defined by the updated NCEP ATP III criteria. Testosterone and E2 levels were measured by liquid and gas chromatography/mass spectrometry respectively. Logistic regression was used to assess the association between sex steroids and incident MetS. Results: 1651 men without MetS at baseline were identified. During follow-up 289 men developed incident MetS, while 1362 men did not develop MetS. Men with lower baseline total T levels were at higher risk for developing MetS (Odds ratio (OR)=1.72, p<0.001), even after adjustment for SHBG (OR=1.43, p=0.001), BMI (OR=1.44, p<0.001) or HOMA-IR (OR=1.64, p<0.001). E2 was not associated with development of MetS (OR=1.04; p=0.56). However, a lower E2/T ratio was associated with a lower risk of incident MetS (OR=0.38; p<0.001), even after adjustment for SHBG (OR=0.48; p<0.001), BMI (OR=0.60; p=0.001) or HOMA-IR (OR=0.41; p<0.001). Conclusions: In men, lower T levels, but not E2, are linked with an increased risk of developing MetS, independent of SHBG, BMI or insulin resistance. A lower E2/T ratio may be protective against developing MetS.
