Abstract
The influence of sex steroids on calcaneal quantitative ultrasound (QUS) parameters was assessed in a population sample of middle-aged and elderly European men. Higher free and total E-2 though not testosterone, were independently associated with higher QUS parameters. The aim of this study was to investigate the association between QUS parameters and sex steroids in middle-aged and elderly European men. Three thousand one hundred forty-one men aged between 40 and 79 years were recruited from eight European centres for participation in a study of male ageing: the European Male Ageing Study. Subjects were invited by letter to attend for an interviewer-administered questionnaire, blood sample and QUS of the calcaneus (Hologic-SAHARA). Blood was assessed for sex steroids including oestradiol (E-2), testosterone (T), free and bio-available E-2 and T and sex hormone binding globulin (SHBG). Serum total T was not associated with any of the QUS parameters. Free T and both free and total E-2 were positively related to all QUS readings, while SHBG concentrations were negatively associated. These relationships were observed in both older and younger (< 60 years) men. In a multivariate model, after adjustment for age, centre, height, weight, physical activity levels and smoking, free E-2 and SHBG, though not free T, remained independently associated with the QUS parameters. After further adjustment for IGF-1, however, the association with SHBG became non-significant. Higher free and total E-2 are associated with bone health not only among the elderly but also middle-aged European men.
