| Popis: | Background The hypertensive disorders of pregnancy include pre‐eclampsia, gestational hypertension, chronic hypertension, and undefined hypertension. Pre‐eclampsia is considerably more prevalent in low‐income than in high‐income countries. One possible explanation for this discrepancy is dietary differences, particularly calcium deficiency. Calcium supplementation in the second half of pregnancy reduces the serious consequences of pre‐eclampsia, but has limited effect on the overall risk of pre‐eclampsia. It is important to establish whether calcium supplementation before, and in early pregnancy (before 20 weeks' gestation) has added benefit. Such evidence could count towards justification of population‐level interventions to improve dietary calcium intake, including fortification of staple foods with calcium, especially in contexts where dietary calcium intake is known to be inadequate. This is an update of a review first published in 2017. |
