Study Groups

Normal iron
Normal iron
The intervention was divided into two stages, the first stage lasted for 4 weeks, and the dosage used was the dietary nutrient recommendation amount, namely the dietary recommendation amount standard for early pregnancy (iron 20mg/d), and the middle stage of pregnancy (iron 24mg/d). The second stage lasts for 4 weeks. For subjects in iron deficiency, the maximum tolerable amount (iron 42mg/d) is used for intervention. For those with good nutritional status, the dietary recommendation amount is maintained.
Weak iron
The intervention was divided into two stages, the first stage lasted for 4 weeks, and the dosage used was the dietary nutrient recommendation amount, namely the dietary recommendation amount standard for early pregnancy (iron 20mg/d), and the middle stage of pregnancy (iron 24mg/d). The second stage lasts for 4 weeks. For subjects in iron deficiency, the maximum tolerable amount (iron 42mg/d) is used for intervention. For those with good nutritional status, the dietary recommendation amount is maintained.

Normal selenium
Normal selenium
The intervention was divided into two stages, the first stage lasted for 4 weeks, and the dosage used was the dietary nutrient recommendation amount, namely the dietary recommendation amount standard for early pregnancy (selenium 60ug/d), and the middle stage of pregnancy (selenium 65ug/d). The second stage lasts for 4 weeks. For subjects in selenium deficiency, the maximum tolerable amount (selenium 400ug/d) is used for intervention. For those with good nutritional status, the dietary recommendation amount is maintained.
