A substantial proportion of pregnant women do not meet the recommended daily calcium intake, even in developed countries. Nonetheless, calcium supplementation is not routinely advised to pregnant women in most countries. We aimed to predict the impact of advising pregnant women to use calcium supplements (1,000\u00a0mg\/day) on the number of cases of pre\u2010eclampsia prevented and related health care costs. By use of a decision\u2010analytic model, we assessed the expected impact of advising calcium supplementation to either (1) all pregnant women, (2) women at high risk of developing pre\u2010eclampsia, or (3) women with a low dietary calcium intake compared with current care. Calculations were performed for a hypothetical cohort of 100,000 pregnant women living in a high\u2010income country, although input parameters of the model can be adjusted so as to fit other settings. The incidence of pre\u2010eclampsia could be reduced by 25%, 8%, or 13% when advising calcium supplementation to all pregnant women, women at high risk of pre\u2010eclampsia, or women with a low dietary calcium intake, respectively. Expected net financial benefits of the three scenarios were of \u20ac4,621,465, \u20ac2,059,165, or \u20ac2,822,115 per 100,000 pregnant women, respectively. Advising pregnant women to use calcium supplements can be expected to cause substantial reductions in the incidence of pre\u2010eclampsia as well as related health care costs. It appears most efficient to advise calcium supplementation to all pregnant women, not subgroups only.<\/jats:p>","DOI":"10.1111\/mcn.12479","type":"journal-article","created":{"date-parts":[[2017,6,19]],"date-time":"2017-06-19T04:13:14Z","timestamp":1497845594000},"source":"Crossref","is-referenced-by-count":23,"title":["Should women be advised to use calcium supplements during pregnancy?
