2014年2月24日讯 /生物谷BIOON/ --孕妇的流产问题一直是医学界关注的重点。最近英国科学家在Journal of Obstetrics and Gynaecology杂志上发表了一项研究成果,提醒孕妇可以通过改变自己的生活习惯来降低流产的可能性。据调查,英国孕妇中每7名孕妇中就有一名最终流产。针对这一现象,来自University of Copenhagen的Anne-Marie Nybo Andersen领导的研究团队调查分析了1996年到2002年间总计91427名孕妇的研究数据后发现,酗酒女性和经常夜间加班的孕妇流产概率远远高于平均水平。同时体重过高和过低也会增加流产的概率。而这次大样本的调查分析结果也首次直接表明了怀孕状况和生活习惯有直接影响。Anne-Marie Nybo Andersen在文中表示,通过建立正常的生活习惯,超过四分之一的首次怀孕孕妇流产现象可以被避免。(生物谷Bioon.com)

详细英文报道:

More than a quarter of first-time miscarriages could be prevented by making a combination of lifestyle changes, research in Denmark suggests.

Researchers said lifting more than 20kg (44lbs) each day during pregnancy and being obese or underweight increased the risk of miscarriage.

Women beyond their early 30s, who drank alcohol and worked night shifts during pregnancy were also more likely to miscarry, they said.

The study analysed 91,427 women.

In the UK, more than one in seven pregnancies ends in miscarriage.

'Subject for prevention'

Researchers at the University of Copenhagen, which carried out the work, said only by reducing all of the risk factors could they be prevented.

The paper was published in the International Journal of Obstetrics and Gynaecology.

Anne-Marie Nybo Andersen, senior researcher at the University of Copenhagen, said: "The main message from the paper is that miscarriages are a subject for prevention."

Ms Nybo Andersen said the paper was significant as it showed the relative importance of different lifestyle factors in causing miscarriage, rather than more specific factors, such as certain pharmaceutical drugs.

As the findings were from the health perspective of a population, they could apply to lots of people - from individual couples to people in charge of maternity policies, work place regulations and supporting students who get pregnant, she said.

She added: "Everybody, young men and women, as well as those who have political responsibilities should bear in mind that postponing pregnancy to the mid-30s implies a seriously increased risk of miscarriage."

Healthy-pregnancy advice

Pregnancies included in the Danish National Birth Cohort between 1996 and 2002 were analysed for the study. Researchers found 3.5% of the women miscarried.

They looked for links between the miscarriages and lifestyle by collecting data through computer-assisted telephone interviews.

Caroline Overton, spokesperson at the Royal College of Obstetricians and Gynaecologists, said: "This is a very interesting study in terms of the very large population size."

She said it confirmed much of the advice currently given out in the UK to promote healthy pregnancy, such as not drinking, but questioned how applicable the study would be to British women.

On the subject of the findings, Ms Overton added: "Twenty kilograms is the size of a large holiday suitcase. Most of us would only lift that very occasionally."

Women wanting to conceive should also eat a balanced diet, make sure they are not "too skinny", or overweight, cut out smoking and ask their partners to follow suit, she said.
