Abstract

Little is known about the descriptive epidemiology of androgen deficiency. In this study, we sought to address this issue by providing estimates of the crude and age-specific prevalence and incidence rates of androgen deficiency in a randomly sampled population-based cohort of middle-aged and older men. Data on androgen deficiency (defined using both signs/symptoms plus total and calculated free testosterone) were available for n = 1691 (baseline) and n = 1087 (follow-up) men from the Massachusetts Male Aging Study. Crude and age-specific prevalence and incidence rates were calculated. Based on these estimates, projections for the number of cases of androgen deficiency in the 40- to 69-yr-old U.S. male population were computed. Estimates of the crude prevalence of androgen deficiency at baseline and follow-up were 6.0 and 12.3%, respectively. Prevalence increased significantly with age. From baseline age-specific prevalence data, it is estimated that there are approximately 2.4 million 40- to 69-yr-old U.S. males with androgen deficiency. The crude incidence rate of androgen deficiency was 12.3 per 1,000 person-years, and the rate increased significantly (P < 0.0001) with age. Based on these incidence data, we can expect approximately 481,000 new cases of androgen deficiency per year in U.S. men 40-69 yr old.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Testosterone deficiency is highly prevalent, with rates increasing with age from 4% in men aged 40-49 years to nearly 50% in men over 80 years, and some studies suggest a 17% increase per decade of life.

    “Testosterone deficiency is highly prevalent, with rates increasing with age from 4% in men aged 40–49 years to nearly 50% in men over 80 years of age, with some studies suggesting a 17% increase in testosterone deficiency for every decade of life (2-4).”
  • Community prevalence estimates of potentially functional hypogonadism in middle-aged and older men vary from 2.1% to 12.3%.

    “The community prevalence estimates of potentially functional hypogonadism in middle-aged and older men (also referred to as late-onset, age-related, or adult-onset hypogonadism) vary from 2.1% to 12.3% (8–10)”
  • In other observational studies of middle-aged and older men, symptoms and low testosterone also seldomly occurred together.

    “In other observational studies of middle-aged and older men, symptoms and low testosterone also seldomly occurred together (Supplemental Fig. 1) (8–10).”

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.
