Abstract

Summary: Objective: Previous studies suggest that androgens have a sexually dimorphic impact on metabolic dysfunction. However, the sex‐specific link between circulating androgens and risk of type 2 diabetes mellitus (T2DM) has not been examined in a large scale, longitudinal cohort, a task we undertook in this study. Design: A retrospective cohort study in a UK primary care database. Patients: We included men and women with available serum testosterone and sex hormone‐binding globulin (SHBG) results. Measurements: We categorized serum concentrations according to clinically relevant cut‐off points and calculated crude and adjusted T2DM Incidence Rate Ratios (IRRs and aIRRs). Results: Serum testosterone concentrations were available in 70 541 men and 81 889 women; serum SHBG was available in 15 907 men and 42 034 women. In comparison to a reference cohort with serum testosterone ≥20 nmol/L, men with lower serum testosterone had a significantly increased risk of T2DM, with the highest risk in those with serum testosterone <7 nmol/L (aIRR 2.71, 95% CI 2.34‐3.14, P < 0.001). In women, the risk of T2DM started to increase significantly when serum testosterone concentrations exceeded 1.5 nmol/L, with the highest risk in women with serum testosterone ≥3.5 nmol/L (aIRR 1.98, 95% CI 1.55‐2.52, P < 0.001). These observations were verified in a continuous rather than categorized analysis. The risk of T2DM increased in men and women with serum SHBG <40 and <50 nmol/L, respectively. Conclusions/Interpretation: In this longitudinal study, we found sexually dimorphic associations between serum testosterone and risk of incident T2DM. Androgen deficiency and excess should be considered important risk factors for diabetes in men and women, respectively.

  • Lower SHBG was an independent risk factor for the development of T2D, inferring a five- or ninefold higher risk for male and female subjects, respectively, as compared to the reference group.

    “In a large longitudinal cohort study, lower SHBG was an independent risk factor for the development of T2D, inferring a five- or ninefold higher risk for male and female subjects, respectively, as compared to the reference group, hereby confirming findings from smaller studies [117–119].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
