Magnesium supplementation does not reduce the frequency of leg cramps or improve recovery during pregnancy, and it also does not have significant side effects compared to the control group.
Leg cramps are one of the common symptoms during pregnancy. About 30%-50% of pregnant women experience leg cramps twice a week. Leg cramps may cause severe pain and sleep disturbance, hinder performance of daily activities and may lengthen the duration of pregnancy and the type of childbirth. Several randomized controlled trial (RCT) studies focused on the effects of the magnesium supplement for relieving leg cramps. However, the results were inconsistent. Five databases were searched from their inception to July 2, 2020. We summarized the weighted mean difference (WMD) with 95% CIs for the frequency of leg cramps after treatment, and summarized the odds ratio (OR) with 95% confidence intervals (CIs) for recovery from leg cramps and side effects. Four RCTs with a total of 332 pregnant women were identified. The frequency of leg cramps after treatment was not decreased in the treatment group compared to the control group (WMD = -0.47, 95% CI: -1.14-0.20, P = 0.167). Magnesium supplementation cannot improve the recovery from leg cramps compared to the control group (OR = 0.47, 95% CI: 0.14-1.52, P = 0.207). Magnesium supplementation had no significant side effects in the treatment group compared to the control group (OR = 1.82, 95% CI: 0.90-3.69, P = 0.094). Oral magnesium supplementation is not effective in the treatment of leg cramps during pregnancy. Prospero: CRD42020196572. (c) 2021 Taiwan Association of Obstetrics & Gynecology.
