Abstract

CONTEXT: Thyroid dysfunction is one of the leading endocrine disorders. Previous data show that about half of the population with thyroid dysfunction remains undiagnosed. OBJECTIVE: Our objective was to estimate epidemiologic data on thyroid dysfunction in Europe. DATA SOURCES: PubMed, EMBASE, and SCOPUS databases were searched to identify studies that evaluated the prevalence and/or incidence of thyroid dysfunction in Europe published between 1975 and 2012. STUDY SELECTION: Of the 541 identified abstracts examined, 178 were considered for evaluation and 17 were included. Studies were excluded if they included participants with an underlying disease or were limited by age or gender. DATA EXTRACTION: Results were grouped into 3 categories: 1) prevalence of undiagnosed thyroid dysfunction, 2) prevalence of thyroid dysfunction, and 3) incidence of thyroid dysfunction. Extraction was conducted independently by 2 investigators. DATA SYNTHESIS: An empirical Bayesian random-effects model was used. The prevalence of undiagnosed thyroid dysfunction was assessed in 7 studies with a mean result of 6.71% (95% credibility interval, 6.49%-6.93%): 4.94% (4.75%-5.13%) and 1.72% (1.66%-1.88%) for undiagnosed hypothyroidism and hyperthyroidism, respectively. The prevalence of both previously diagnosed and undiagnosed thyroid dysfunction was assessed in 9 studies with a mean result of 3.82% (3.77%-3.86%): 3.05% (3.01%-3.09%) and 0.75% (0.73%-0.77%) for hypothyroidism and hyperthyroidism, respectively. The incidence rate of thyroid dysfunction was assessed in 7 studies with a mean result of 259.12 (254.39-263.9) per 100 000 per year: 226.2 (222.26-230.17) and 51 (49.23-52.88) per 100 000 per year for hypothyroidism and hyperthyroidism, respectively. CONCLUSION: This meta-analysis provides extensive data on the prevalence and incidence of thyroid dysfunction in Europe.

  • The prevalence of hypothyroidism in North America and Europe ranges from 0.3% to 2%.

    “The prevalence in North America and Europe ranges from 0.3%to2%, 3-5 but may affect up to 12% of the population, primarily as subclinical hypothyroidism,withhigherprevalenceinareaswith inadequate nutritional iodine levels. 2,6”

    From Hypothyroidism: A Review (2025) · cites this paper as [3]

    The “Prevalence of thyroid dysfunction” section reports hypothyroidism prevalence of 3.05% in Europe, above the claimed 2% upper bound. The Discussion also reports unknown hypothyroidism in 4.6% of a U.S. sample. The paper does not support a 0.3%–2% range for hypothyroidism across North America and Europe. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • Primary hypothyroidism has a female:male ratio of approximately 5:1.

    “Primary hypothyroidism has a female:male ratio of approximately5:1. 3”

    From Hypothyroidism: A Review (2025) · cites this paper as [3]

    The Incidence of thyroid dysfunction section reports hypothyroidism rates of 369.96 per 100,000 per year in females and 72.48 in males, approximately a 5:1 ratio. The paper reports this for hypothyroidism in Europe but does not specify that the ratio applies to primary hypothyroidism. (LLM, conf=0.87)

  • Undiagnosed thyroid disease may be common among the general population.

    “There is less of a consensus regarding screening of the population for undiagnosed thyroid disease, which may be common among the general population.”
  • A meta-analysis of studies from Europe found a prevalence of undiagnosed hyperthyroidism of about 2%.

    “A meta-analysis of studies from Europe found a high prevalence of undiagnosed hypothyroidism of about 5% and of undiagnosed hyperthyroidism of about 2% [5].”

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.
