Abstract

Objectives Studies have suggested that ethnicity and environment may influence thyroid disease. We aim in this study to determine the prevalence of thyroid disease among Saudi (Arab) patients with laboratory-diagnosed obstructive sleep apnea (OSA) and the characteristics and predictors of thyroid disease associated with OSA. Methods Serum thyroid-stimulating hormone (TSH) and free-thyroxine (FT4) levels were measured in all patients referred to the sleep disorders center for an overnight sleep study. The levels were measured within 4 weeks of the sleep study. Type I attended polysomnography (PSG) was performed for all patients. Results During the study period, 271 patients with OSA and a mean age of 48.7 ± 14.1 yr, a body mass index (BMI) of 37.7 ± 9.6 kg/m(2) and an AHI of 55.2 ± 37/hr as well as 76 non-OSA patients with a mean age of 40.8 ± 14.9 yr, a BMI of 33.7 ± 8.9 kg/m(2) and an AHI of 3.8 ± 3.1/hr underwent thyroid function tests. In the OSA patients, the prevalence of newly diagnosed clinical hypothyroidism was 0.4%, and the prevalence of newly diagnosed subclinical hypothyroidism was 11.1%. In the non-OSA patients, the prevalence of newly diagnosed clinical hypothyroidism was 1.4%, and the prevalence of newly diagnosed subclinical hypothyroidism was 4%. There were no cases of clinical or subclinical hyperthyroidism in the studied group. Female gender was the only predictor of clinical hypothyroidism. Conclusion In the OSA patients, the prevalence of newly diagnosed clinical hypothyroidism was low; however, subclinical hypothyroidism was common among patients with OSA.

  • Bahammam et al. evaluated 271 patients referred for sleep studies and found that among patients with confirmed OSA, the prevalence of newly diagnosed clinical hypothyroidism was 0.4%, whereas it was 1.4% in patients without OSA.

    “A study by Bahammam et al. (20) evaluated 271 patients referred for sleep studies and measured the patients’ TSH and T4 levels to determine the prevalence of thyroid disease. Among the patients with confirmed OSA, the prevalence of newly diagnosed clinical hypothyroidism was 0.4%, whereas it was 1.4% in patients without OSA.”

    From Thyroid Dysfunction and Sleep Disorders (2021) · cites this paper as [20]

    The Results report the claimed 0.4% and 1.4% prevalences of newly diagnosed clinical hypothyroidism. However, 271 was the number of patients with OSA, not the total referred group: the study also tested 76 patients without OSA. (LLM, conf=0.93)

    Experimental — accuracy not yet measured

  • Bahammam et al. showed that the prevalence of newly diagnosed clinical hypothyroidism in OSAS patients is low while subclinical hypothyroidism is common.

    “Interestingly, Bahammam et al. [1] showed that the prevalence of newly diagnosed clinical hypothyroidism in OSAS patients is low while subclinical hypothyroidism is common.”

    From Sleep apnea syndrome and hypothyroidism (2013) · cites this paper as [1]

  • In Bahammam et al.'s study, the prevalence of newly diagnosed subclinical hypothyroidism was 11.1% for patients with OSA and 4% for patients without OSA.

    “However, the prevalence of newly diagnosed subclinical hypothyroidism was 11.1% for patients with OSA and 4% of patients without OSA.”

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.
