[Prevalence of thyroid function in pregnant and lactating women in areas with different iodine levels of Shanxi province].

To investigate the effects of high iodine intake on thyroid function in pregnant and lactating women. A cross sectional epidemiological study was conducted among 130 pregnant women and 220 lactating women aged 19-40 years in areas with high environment iodine level (>300 μg/L) or proper environment iodine level (50-100 μg/L) in Shanxi in 2014. The general information, urine samples and blood samples of the women surveyed and water samples were collected.

Dried Blood Spot Thyroglobulin as a Biomarker of Iodine Status in Pregnant Women.

Context: Thyroglobulin (Tg) could be a sensitive biomarker of iodine nutrition in pregnant women (PW). A dried blood spot (DBS) assay would simplify collection and transport in field studies.

Objectives: Our aims were to (1) establish and test a reference range for DBS-Tg in PW; (2) determine whether co-measurement of Tg antibodies (Abs) is necessary to define population iodine status.

[Epidemiological investigation on thyroid disease among fertile women in different iodine intake areas of Shanxi province].

Objective: To understand the prevalence of thyroid diseases and its influencing factors of iodine on thyroid gland function and autoimmune among fertile women in different iodine intake areas.

Methods: Cross-sectional method was used for descriptive epidemiology. 236 women aged 19 to 45 years were sampled in 2011, in Shanxi province.
