Objective:

To demonstrate that hypomagnesemia is a risk factor for severe preeclampsia.

Materials and methods:

A case-control study conducted in patients treated at the Hospital de la Mujer between the months of January 2015 and January 2016. The study group included patients with severe preeclampsia and healthy pregnant controls with determination of concentrations of magnesium serum.

Results:

200 patients were studied; the average age of the hypertensive pregnant women was 24.6 years, and 23.5 years of the normotensive women. The difference between the two was 1.1 years (p > 0.05). The median in weeks of gestation of hypertensive women was 37 and 39 for healthy women, respectively; the difference was 2 (p = 0.0001). The median magnesium of the hypertensive women was 1.7 mg/dL, and in the non-hypertensive 1.8 mg/dL, (p = 0.0053); RM: 1.72 IC95%: 1.0- 3.13; p = 0.005.

Conclusions:

in this study group, it was shown that hypomagnesemia is a risk factor for severe preeclampsia.
