Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* To analyse the longitudinal changes of urinary iodine, urinary iodine/creatinine ratio, thyroid function and related factors in different periods of early, middle, late pregnancy and 6 weeks postpartum in Beijing area.
* To explore the relationship between iodine nutrition status and the changes of thyroid function and to further clarify the effect of iodine nutrition status on thyroid function of women of childbearing age during pregnancy and postpartum in combination with dietary intake of iodine questionnaire.
Participants will be detected there thyroid function, the level of median urinary iodine and urinary iodine/creatinine.
Researchers will compare healthy women of childbearing age served as the control group in the same period.
