妇女围受孕期服用FA或MM的依从性得分与孕早期血清Vit.E浓度的关系

The association between compliance score of taking FA or MM during periconceptional period and serum Vit.E concentration in the 1st trimester of gestational period among the women

Compliance score	n	Vit.E concentration/(mg/L)		β	Adjusted βa
		x±s	Median (P25-P75)
The compliance of FA or MM supplementation was divided into no-use (score=0), irregular use and initiated after pregnancy (score=1), irregular use and initiated before pregnancy (score=2)，regular use and initiated before pregnancy (score=3). Consideration of the number of women who started to take FA regularly initiating after pregnancy was only 2, and the number of women who take MM regularly initiating after pregnancy was 9, the two groups were deleted in the analysis. a, the confounding factors adjusted in the multivariate Logistic regression model include: delivery year, age, education level, household registration, occupation, pre-pregnancy body mass index, parity. FA, folic acid only; MM, multiple micronutrients. *P < 0.05; #P < 0.001.
