Effects of Vitamin D in Pregnancy on Maternal and Offspring Health-Related Outcomes: An Umbrella Review of Systematic Review and Meta-Analyses
Open accessAbstract
Background: Vitamin D deficiency has been linked with several adverse maternal and fetal outcomes. Objective: To summarize systematic reviews and meta-analyses evaluating the effects of vitamin D deficiency and of vitamin D supplementation in pregnancy on maternal and offspring health-related outcomes. Methods: Prior to conducting this umbrella review, we registered the protocol in PROSPERO (CRD42022368003). We conducted searches in PubMed, Embase, and Cochrane Library for systematic reviews and meta-analyses on vitamin D in pregnancy, from database inception to October 2, 2023. All outcomes related to vitamin D in pregnancy obtained from the systematic reviews and meta-analyses were extracted. Data Extraction: Two reviewers independently chose studies and collected information on health outcomes. The quality of the included articles’ methodology was assessed using AMSTAR 2 (A Measurement Tool to Assess Systematic Reviews–2). Results: We identified 16 eligible systematic reviews and meta-analyses, which included 250,569 women. Our results demonstrated that vitamin D deficiency in pregnancy is associated with increased risk of preterm birth, small-for gestational age/low birth weight infants, recurrent miscarriage, bacterial vaginosis and gestational diabetes mellitus. Vitamin D supplementation in pregnancy increases birth weight, and reduces the risk of maternal pre-eclampsia, miscarriage, and vitamin D deficiency, fetal or neonatal mortality, as well as attention-deficit hyperactivity disorder, and autism spectrum disorder in childhood. In women with gestational diabetes mellitus, vitamin D supplementation in pregnancy can reduce the risk of maternal hyperbilirubinemia, polyhydramnios, macrosomia, fetal distress, and neonatal hospitalization. Conclusion: Due to the association with adverse maternal and offspring health outcomes, we recommend the vitamin D status in pregnancy should be monitored, particularly in women at high risk of vitamin D deficiency. It is suggested that pregnant women take a dose of >400 IU/day of vitamin D supplementation during pregnancy to prevent certain adverse outcomes.

Low vitamin D levels in pregnant women, especially those who are obese, have been associated with disruptions in glucose and lipid metabolism, which may contribute to higher risks of diabetes and obesity later in life for their offspring.
“Low vitamin D levels in pregnant women, especially those who are obese, have been associated with disruptions in glucose and lipid metabolism, which may contribute to higher risks of diabetes and obesity later in life for their offspring.”
From Maternal Overnutrition and Fetal Programming: Long-Term Metabolic, Cognitive, and Epigenetic Consequences (2026) · cites this paper as [141]
In Results, the observational-studies section reports lower maternal vitamin D levels among children with type 1 diabetes, and the section on women with gestational diabetes reports changes in maternal glucose and lipid measures after vitamin D supplementation. The paper does not establish that these associations are especially pronounced in obese pregnant women, or that disrupted maternal metabolism contributes to offspring obesity later in life. No page numbers are available in our copy. (LLM, conf=0.86)
Experimental — accuracy not yet measuredVitamin D deficiency during pregnancy is linked to adverse outcomes not only at birth but also for long-term health of both mothers and their children.
“It is now widely recognized that vitamin D deficiency during pregnancy is linked to adverse outcomes not only at birth but also for long-term health of both mothers and their children.”
From Maternal Overnutrition and Fetal Programming: Long-Term Metabolic, Cognitive, and Epigenetic Consequences (2026) · cites this paper as [141]
The Discussion’s Principal findings link vitamin D deficiency during pregnancy to adverse maternal and offspring outcomes, including pregnancy and birth outcomes. The Results section also reports associations with childhood developmental outcomes. However, the maternal outcomes reported concern pregnancy; the paper does not establish long-term health effects for mothers. (LLM, conf=0.87)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
