Resumen
PERICHART-PERERA, Otilia y RODRIGUEZ-CANO, Ameyalli M. Micronutrient supplementation during pregnancy: narrative review of systematic reviews and meta-analyses. Ginecol. obstet. Méx. [online]. 2022, vol.90, n.12, pp.968-994. Epub 14-Abr-2023. ISSN 0300-9041. https://doi.org/10.24245/gom.v90i12.8010.
OBJECTIVE:
To describe the effects of vitamin B12, vitamin D, calcium, magnesium, zinc and multiple micronutrient (MMS) supplementation on perinatal complications. METHODS: We performed a search of systematic reviews/meta-analyses of supplementation in healthy women, and/or with metabolic disorders, with a single pregnancy (Medline/PubMed; 2012-2022).
RESULTS:
51 reviews/meta-analyses were included. Vitamin D supplementation appears to reduce the risk of gestational diabetes (GDM) and preeclampsia; and possibly the risk of low birth weight (LBW) and small for gestational age (SGA). Calcium supplementation reduces the risk of gestational hypertension, preeclampsia, in women at high risk and with low calcium intake. MMS showed an effect in reducing LBW, SGA, stillbirth, and possibly preterm birth. Few studies reported that magnesium supplementation could decrease maternal hospitalization and improve glycemic control in women with GDM. More studies on vitamin B12, zinc and magnesium supplementation are required.
CONCLUSION:
There is no single effective micronutrient supplementation scheme for all women; this must be individualized in terms of the type of nutrient, dose, specific characteristics, individual risks and context of each woman, her dietary intake/micronutrient deficiencies, among others. Supplementation should be part of a policy to improve gestational clinical care, ensure food security and improve public health conditions.
