Abstract Title:
The effect of folic acid throughout pregnancy among pregnant women at high risk of pre-eclampsia: A randomized clinical trial.
Abstract:
BACKGROUND: Pre-eclampsia is a serious hypertension disease that occurs during pregnancy. Folic acid (FA) supplementation has been reported to reduce pre-eclampsia risk in pregnant women. Here, we aimed to assess whether treatment of high doses of FA in pregnant women with high pre-eclampsia risk could prevent the onset of pre-eclampsia.METHODS: We conducted a randomized clinical trial in 1576 women who had pre-eclampsia or eclampsia in their last pregnancy and had a pregnancy plan. Subjects were randomized into two groups. The low dose (LD) group (n = 788) received 0.4 mg of FA daily from the first 3 months of pregnancy until the entire pregnancy, and the high dose (HD) group (n = 788) received 4 mg of FA per day. We followed up the subjects until production.RESULTS: The plasma homocysteine (homocysteine) and FA levels were significantly higher in the HD group that in the LD group. Severe gestational hypertension, early onset pre-eclampsia (
