Abstract:
Objective To assess the prevalence,development and prognosis of thyroid disorders in adult healthy subjects aged over 60 years.Methods We performed a cross-sectional study in 1999 and a 5-year follow-up study in 2004.A total of 102 men and 147 women aged 60 to 88 years from rural communities in north China were studied.Serum thyrotropin(TSH),thyroid peroxidase antibody(TPOAb)and thyroglobulin antibody(TgAb)were determined by an immunochemiluminometry assay in all participants.Free triiodothyronine(FT_3)and free thyroxine(FT_4)were determined in subjects with abnormal TSH results.Results We dropped the reference range for TSH into 0.28~4.75 mU/L.The prevalence of thyroid dysfunction,positive TPOAb and TgAb was 10.84%,12.85%and 11.65%,respectively.six newly diagnosed patients were found in the follow-up study,3 cases(all women)with hypothyroidism and 3(all men)with hyperthyroidism.Conclusion The high prevalence of thyroid dysfunction in the elderly indicates screening is necessary.Most elderly patients with subclinical dysfunction can recover spontaneously.The strategy should be focused on whether we monitor these patients.
