Relationship of subclinical hypothyroidism with gestational diabetes mellitus during early pregnancy / 中华内分泌代谢杂志

ABSTRACT

A screening of thyroid function was performed in 2 320 pregnant women whose gestational age was less than 12 weeks.The incidence of subclinical thyroid disease and its relationship with gestational diabetes mellitus were analyzed.The results showed that there were 8 patients (0.34％) with clinical hypothyroidism,226 (9.74％) with subclinical hypothyroidism,and 14 patients (0.6％) with hyperthyroidism among 2 320 pregnant women.The prevalence of gestational diabetes mellitus in pregnant women with subclinical hypothyroidism was apparently higher than that in normal pregnant women (33.3％ vs 12.9％,P＜0.05),suggesting that the increased incidence of gestational diabetes mellitus seems to be related to subclinical hypothyroidism during early pregnancy.Therefore,it is important to screen the function of thyroid during early pregnancy
