Skinny or underweight women at greater risk of miscarriage 研究表明：過瘦女性易流產

According to a new study, thin or skinny women who get pregnant are 72 percent more likely to miscarry in the first three months of pregnancy than their normal weight counterparts. However, the risk can be reduced up to 50 percent by eating the right food or taking multivitamins like folic acid, say researchers.

The researchers from the London School of Hygiene and Tropical Medicine carried out their study on 603 British women aged 18 to 55 who had miscarried within three months of getting pregnant.

BBC reports that the new research also indicated that eating fruit and vegetables, and also chocolate, helped reduce the risk of miscarriage.

Those classed as underweight had had a body mass index under 18.5.

Additionally, unmarried women or those living with a partner were also at a greater risk than those who "planned" their pregnancies. Planning parents were 40 per cent less likely to miscarry than those for whom conception was an accident.

The research also discovered that woman who separated from their partners after becoming pregnant increased her odds of a miscarriage by 60 per cent.

If a woman has had a previous abortion, it also raised the chances of a subsequent miscarriage by more than 60 percent, while fertility problems were associated with 41 per cent higher odds.

The research leader, Noreen Maconochie, a senior lecturer at the London School of Hygiene and Tropical Medicine said, "The findings related to low pre-pregnancy weight, previous termination, stress and change of partner are noteworthy, and we suggest further work be initiated in other study populations."

一項最新研究表明，過瘦的女性在懷孕前三個月流產的幾率比正常體重的女性高72%。但據研究人員介紹，合理的飲食及攝取如葉酸等多種維生素可將這一風險降低至50%。

倫敦衛生及熱帶醫學院的研究人員對603名年齡在18至55歲之間的英國女性進行了調查，這些女性均有懷孕前三個月內流產的經歷。

據英國廣播公司報道，這項最新研究還發現，女性在懷孕期間多吃水果、蔬菜和巧克力也有助于降低流產的風險。

體重指數低于18.5的人被認定為“過瘦”。

此外，未婚女性和同居女性意外懷孕后流產的風險比“有計劃”懷孕的女性高。“有計劃”懷孕的女性流產幾率比意外懷孕的女性低40%。

研究同時發現，女性在懷孕期間與伴侶分居，發生流產的可能性要比正常情況高60%。

此外，有墮胎史及有生育問題的女性流產幾率分別高出60%和41%。

研究小組組長、倫敦衛生及熱帶醫學院高級講師諾琳·麥克諾奇說：“這些研究結果很有意義，體重過輕、有過墮胎史、壓力過大及與伴侶分居等易造成流產的幾個因素應引起女性的注意，同時我們希望這一研究能盡快在別國進行。”
