Abstract

OBJECTIVES: To explore the associations between frailty and reproductive axis hormones (as an important regulatory system) in middle aged and older men. DESIGN: Cross‐sectional. SETTING: The European Male Aging Study. PARTICIPANTS: Three thousand two hundred nineteen community‐dwelling European men aged 40 to 79. MEASUREMENTS: Interviewer‐assisted questionnaires to assess physical activity, health status, and mood were administered. Testosterone (T), luteinizing hormone (LH), follicle‐stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEAS), and sex hormone–binding globulin (SHBG) were measured in a fasting morning blood sample. Frailty was assessed as an index (FI) according to the number (out of 43 possible) of health deficits (symptoms, signs, and functional impairments). Relationships between FI and hormone levels (as outcomes) were explored using regression models. RESULTS: Mean FI was 0.12 ± 0.11 (range 0–0.67) was highest in the oldest group. After adjustment for confounders, higher levels of FI were significantly associated with lower levels of total T, free T, and DHEAS and higher levels of gonadotropins and SHBG; a 1‐standard deviation cross‐sectional increase in FI was associated with a regression coefficient of −0.30 nmol/L (95% confidence interval (CI)=−0.53 to −0.07) decrease in total T and 0.66 U/L (95% CI=0.48–0.83) increase in LH. CONCLUSIONS: The associations between high FI, high gonadotropins, and well‐maintained circulating T suggest that these changes are markers of aging‐related disruptions of multiple physiological regulation, of which alterations in pituitary–testicular function represent a sensitive marker rather than an underlying pathogenic mechanism for frailty.

  • Testosterone levels have been linked to frailty, but this may reflect a sensitive marker rather than a causal mechanism.

    “Although an association between testosterone levels and frailty has been identified (44) this may be a sensitive marker rather than a pathological mechanism (45).”

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.
