Abstract

CONTEXT: The distribution of serum TSH shifts progressively to higher concentrations with age. OBJECTIVE: The aim of the study was to determine whether the population shift in TSH distribution to higher concentrations with aging extends to people of exceptional longevity, namely centenarians, and to assess the relationship between concentrations of TSH and free T(4) (FT4). DESIGN/SETTING/PATIENTS: We analyzed TSH, FT4, and TSH frequency distribution curves in thyroid disease-free Ashkenazi Jews with exceptional longevity (centenarians; median age, 98 yr), in younger Ashkenazi controls (median age, 72 yr), and in a population of thyroid disease-free individuals (median age, 68 yr) from the U.S. National Health and Nutrition Examination Survey 1998-2002 (NHANES controls). RESULTS: Serum TSH was significantly higher in centenarians [1.97 (0.42-7.15) mIU/liter] than in Ashkenazi controls [1.55 (0.46-4.55) mIU/liter] and NHANES controls [1.61 (0.39-6.29) mIU/liter] (median, 2.5 and 97.5 centiles) (P < 0.001). The TSH frequency distribution curve of centenarians was relatively similar in shape to controls but shifted significantly to higher TSH, including TSH concentration at peak frequency. The TSH distribution curve of the NHANES control group was superimposable to and not significantly different from the Ashkenazi controls. FT4 was similar in centenarians and Ashkenazi controls, and there was a significant inverse correlation between FT4 and TSH in both groups. CONCLUSIONS: The TSH population shifts to higher concentrations with age appear to be a continuum that extends even to people with exceptional longevity. The inverse correlation between TSH and FT4 in our populations suggests that changes in negative feedback may contribute to exceptional longevity.

  • In individuals with genetically higher TSH concentrations there is enhanced longevity.

    “Furthermore, in individuals with genetically higher TSH concentrations there is enhanced longevity.134”

    From Hypothyroidism (2024) · cites this paper as [134]

    The Abstract reports higher serum TSH in Ashkenazi centenarians than in younger controls, supporting an association with exceptional longevity. The study does not establish that their higher TSH was genetic or that it enhanced longevity; the Discussion describes a favorable role in healthy aging as a possibility and lists other possible explanations for elevated TSH.

  • Studies in several populations have shown progressively increasing TSH concentrations with age.

    “Studies in several populations (Americans, Scottish, Ashkenazi Jews, Chinese) have shown progressively increasing TSH concentrations with age.”
  • The 97.5th percentiles of the reference population are considerably higher in the elderly (older than 70 years old) than in younger adults.

    “The 97.5th percentiles of the reference population are considerably higher in the elderly (older than 70 years old) than in younger adults [32–35], which is not explained only by higher prevalence of thyroid autoimmunity [36, 37].”
  • Longevity was associated with higher TSH concentrations in the Ashkenazi population and confirmed by two Dutch studies.

    “Longevity was associated with higher TSH concentrations in the Ashkenazi population (19) and confirmed by two Dutch studies (the Leiden 85-Plus Study and the Leiden Longevity Study) (33–35).”
  • Studies in the oldest centenarians indicate that individuals with genetically higher TSH concentrations have enhanced longevity.

    “Studies in the oldest centenarians indicate that individuals with genetically higher TSH concentrations have enhanced longevity [105].”

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.
