研究表明 維生素D缺乏可能增加流產的風險大綱

Women not receiving enough vitamin D take longer to get pregnant and may even increase their risk of having a miscarriage, a study has found.

一項研究發現，沒有攝入足夠維生素D的女性需要更長的時間才能懷孕，甚至可能面臨更高的流產風險。

Researchers analyzed levels of the essential nutrient in the blood, before pregnancy and eight weeks after, of 1,200 women who had experienced a previous pregnancy loss and were hoping to conceive again.

研究人員比對分析了1200名女性孕前和孕後8周血液中必需營養素的水平，這些女性此前都曾經歷過妊娠失敗，並希望能重新受孕。

Those whose vitamin D levels were in line with recommended levels prior to conception were 15% more likely to have a live birth, and risk of miscarriage decreased as levels of the vitamin rose.

那些在孕前體內維生素D水平與推薦水平一致的女性活產的可能性要高出15%，流產風險會隨着維生素D水平的提高而降低。

"Our findings suggest that vitamin D may play a protective role in pregnancy," said Dr Sunni Mumford from the Eunice Kennedy Shriver National Institute of Child Health and Human Development in Rockville, Maryland.

馬里蘭州羅克維爾市尤妮斯甘乃迪施萊佛國家兒童健康與人類發展研究所的桑尼·芒福德博士表示：“我們的發現表明維生素D可能在懷孕中起到保護作用。”

The findings add to earlier studies which had suggested higher levels of vitamin D were beneficial in women undergoing in vitro fertilization.

這一發現進一步證實了早前的研究，即高水平的維生素D對人工授精的婦女有益。

In fact, vitamin D is also essential for the human body to absorb calcium and other minerals from the food and drinks we consume.

實際上，維生素D也是人體從食物和飲料中吸收鈣和其他礦物質的必需物質。

Deficiencies can cause bone weakness and deformities, particularly in children who are growing rapidly where it can lead to rickets.

維生素D攝入不足會導致骨質疏鬆或骨頭變形，尤其對於快速長身體的孩子而言，缺乏維生素D可能導致佝僂病。
