Relationship of subclinical hypothyroidism with metabolic syndrome and its components / 中华内分泌代谢杂志

ABSTRACT

The relationship between subclinical hypothyroidism (SCH) and the components of metabolic syndrome (MS) was explored.A total of 2 252 subjects aged 20 to 79 years from medical examination were identified.The prevalence of SCH was 4.88％.The rate of 7.30％ in female was markedly higher than 2.17％ in male(P＜0.01).The highest SCH prevalence in adults was in the ≥70 years old group.The prevalence of SCH in female was increased with age(P＜0.01).Compared with the euthyroid group,body mass index,triglyceride,and low density lipoprotein-cholesterol were significantly elevated (P＜0.05),while high density lipoprotein-cholesterol was significantly decreased in SCH group(P＜0.05).The incidences of hypertension,dyslipidosis,and MS in SCH group were significantly higher than those in euthyroid group(P＜0.05 or P＜0.01) ; Serum TSH in the MS group was higher than that in the Non-MS group[(2.43 ± 1.55 vs 2.21 ± 1.48) mU/L,P＜0.01].The incidence of SCH in MS group was significantly higher than that in the Non-MS group (7.69％ vs 4.25％,P＜0.05).The prevalence of SCH in women was increased with age.Multiple factors of dysbolism were clustered in subjects with SCH.There is a correlation between SCH and MS.
