Background Emerging data from longitudinal studies suggest that low sex steroid concentrations in men are associated with increased cardiovascular risk and mortality. The impact of longitudinal trajectory patterns from serial sex steroid and gonadotrophin measurements on the observed associations is unknown to date. Methods We prospectively evaluated 254 elderly men (mean age, 75 center dot 5years) of the Framingham Heart Study with up to four serial measurements of serum total testosterone (TT), dehydroepiandrosterone sulphate (DHEAS), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and total estradiol (EST); and constructed age- and multivariable-adjusted Cox proportional hazard regression models relating baseline hormone concentrations and their mean, slope and variation over time (modelled as continuous and categorized into quartiles) to the incidence of clinical cardiovascular disease (CVD) and all-cause mortality at 5- and 10-year follow-up. Results We observed no association between baseline concentrations of sex steroids, gonadotrophins and their trajectories with incident clinical CVD over 5- and 10-year follow-up. Although higher baseline TT concentrations were associated with lower mortality risk at 5years (hazard ratio per quartile increment, 0 center dot 74; 95% confidence interval, 0 center dot 560 center dot 98), correction for multiple statistical testing (P<0 center dot 005) rendered this association statistically nonsignificant. Repeat analyses at the 10-year follow-up time point also demonstrated no significant association between sex steroids, gonadotrophins or their trajectories and mortality. Conclusion Investigating longitudinal trajectory patterns of serial sex steroid and gonadotrophin measurements, the present study found no consistent associations with incident clinical CVD and all-cause mortality risk in elderly men from the community.
