Pregnancy and Birth to 24 Months Systematic Review

Systematic Review Question

What is the relationship between dietary patterns before and during pregnancy and risk of hypertensive disorders of pregnancy?

Conclusion Statement

Limited evidence in healthy Caucasian women with access to health care suggests that dietary patterns before and during pregnancy higher in vegetables, fruits, whole grains, nuts, legumes, fish, and vegetable oils and lower in meat and refined grains are associated with a reduced risk of hypertensive disorders of pregnancy, including preeclampsia and gestational hypertension. Not all components of the assessed dietary patterns were associated with all hypertensive disorders.

Grade: Limited

Evidence is insufficient to estimate the association between dietary patterns before and during pregnancy and risk of hypertensive disorders of pregnancy in minority women and those of lower socioeconomic status. 

Grade: Grade Not Assignable
