Association of sex hormone-binding globulin and free testosterone with mortality in men with type 2 diabetes mellitus

Abstract

Objective: Low circulating testosterone levels have been associated with increased mortality in men. We hypothesized that the prognostic role of testosterone in men with type 2 diabetes mellitus (T2DM) is influenced by its carrier protein sex hormone-binding globulin (SHBG). Design: We conducted a prospective cohort study at a tertiary referral centre. Methods: In total, 531 men with T2DM presenting to a diabetes clinic in 2004-2005 were followed prospectively until death, or July 31, 2014, and a survival analysis was performed. The main outcome measure was all cause mortality. Results: Over a mean (S.D.) follow up of 7.6 years (2.6) 175 men (33%) died. In Cox proportional hazard models both..
