“…Mannion et al interviewed 264 women who agreed to participate out of 1000 who were attending a prenatal course in Alberta, Canada. 96 They calculated calcium intake using an FFQ via telephone and included the use of calcium supplements and antacids with calcium. They acknowledge the difficulty of the methodology used to estimate antacid intake and state that a 500mg/day dose was used when information was missing.…”

Background Evidence shows that adequate calcium intake during pregnancy reduces the risk of hypertensive disorders of pregnancy. In most low‐ and middle‐income countries ( LMIC s) the daily calcium intake is well below recommendations. Mapping calcium intake during pregnancy worldwide and identifying populations with low calcium intake will provide the evidence base for more targeted actions to improve calcium intake. Objective To assess dietary calcium intake during pregnancy worldwide. Search strategy MEDLINE and EMBASE (from July 2004 to November 2017). Selection criteria Cross‐sectional, cohort, and intervention studies reporting calcium intake during pregnancy. Data collection and analysis Five reviewers working in pairs independently performed screening, extraction, and quality assessment. We reported summary measures of calcium intake and calculated the weighted arithmetic mean for high‐income countries ( HIC s) and LMIC s independently, and for geographic regions, among studies reporting country of recruitment, mean intake, and total number of participants. When available, inadequate intakes were reported. Main results From 1880 citations 105 works met the inclusion criteria, providing data for 73 958 women in 37 countries. The mean calcium intake was 948.3 mg/day (95% CI 872.1–1024.4 mg/day) for HIC s and 647.6 mg/day (95% CI 568.7–726.5 mg/day) for LMIC s. Calcium intakes below 800 mg/day were reported in five (29%) countries from HIC s and in 14 (82%) countries from LMIC s. Conclusion These results are consistent with a lack of improvement in calcium dietary intake during pregnancy and confirm the gap between HIC s and LMIC s, with alarmingly low intakes recorded for pregnant women in LMIC s. From the public health perspective, in the absence of specific local data, calcium supplementation of pregnant women in these countries should be universal. Tweetable abstract Despite dietary recommendations, women in LMIC s face pregnancy with diets low in calcium.

“…Adverse effects on foetal health are prematurity, reduced intrauterine growth resulting in lower birthweight, and most importantly, poor bone mineralisation. Adverse maternal outcomes related to poor calcium supply during pregnancy include hypertensive disorders such as pre‐eclampsia 8–13 . The World Health Organization (WHO) recommends calcium supplementation of 1500–2000 mg/d for the prevention of pre‐eclampsia, which is still one of the main causes for maternal death, especially in low‐ and middle‐income countries (LMICs) 9,11,12,46,47 …”

“…Calcium specifically plays a major role for the mineralisation of the foetal skeleton, especially during the last gestational trimester and thus, contributes to normal foetal growth. As insufficient calcium is linked to hypertensive disorders like pre‐eclampsia that is associated with an increased risk of maternal mortality and severe foetal outcome the WHO recommends daily calcium supplementation to prevent those morbidities 8–13 …”

[8][9][10][11][12][13] The assumption that dietary calcium intake of vegans is below calcium status compared to vegetarians and omnivores in nonpregnant women and men of different ages is described by various studies.

BackgroundVegetarian diets are currently experiencing increasing popularity and are also becoming more common in pregnant women. Calcium plays a crucial role for skeletal health and for physiologic processes during pregnancy for the mother and foetus.AimsOur study aimed to evaluate calcium intake of vegetarian versus nonvegetarian expectant mothers.Materials and MethodsWe searched PubMed and retrieved seven studies (six prospective cohort and one cross‐sectional) for inclusion in our random‐effects meta‐analysis. We calculated standardised mean differences (SMD).ResultsResults showed a significantly higher calcium intake in vegetarian than nonvegetarian pregnant women [SMD: 0.25; 95% confidence interval (CI): 0.14, 0.36].DiscussionMost studies showed that the recommendations for calcium intake during pregnancy (ranging from 700 to 1200 mg/d) were met. Both vegetarian and nonvegetarian pregnant women showed higher calcium intakes in Europe and North America than in Asia. Serum calcium levels did not differ between vegetarian and nonvegetarian pregnant women (SMD: − 0.15; 95% CI: −0.42, 0.11), confirming that the tight regulation of calcium metabolism is not affected by dietary calcium intake.ConclusionTo prevent inadequate calcium intake potentially associated with adverse gestational outcomes, we recommend adherence to existing recommendations by means of calcium supplementation (1.5–2 g/d), food fortification strategies, or behavioural interventions.
