N-3 fatty acids supplementation reduces preeclampsia during pregnancy

Objectives:
The efficacy of n-3 fatty acids supplementation on the prevention of pregnancy-induced hypertension or preeclampsia remains unclear. Therefore, this meta-analysis (systematic review) has been conducted.

Does n-3 fatty acids supplementation (EPA and/or DHA and/or ALA) decrease risk of pregnancy-induced hypertension and preeclampsia during pregnancy?

Study design:
This review article included 14 RCTs.

Results and conclusions:
The investigators found that n-3 fatty acids supplementation significantly reduced risk of preeclampsia with 18% [RR = 0.82, 95% CI = 0.70 to 0.97, p = 0.024. I2 = 19.0%].
However, n-3 fatty acids supplementation did not associated with a reduced risk of pregnancy-induced hypertension [RR = 0.98, 95% CI = 0.90 to 1.07, p = 0.652, I2 = 0%].

The investigators concluded n-3 fatty acids supplementation (EPA and/or DHA and/or ALA)  reduces risk of preeclampsia during pregnancy.
