【medical-news】老龄妈妈“也健康”
Older mums 'just as healthy'

WOMEN who give birth in their fifties are just as healthy, both physically and psychologically, as those who start families much earlier in life, according to new research that will significantly strengthen the case against upper age limits for fertility treatment.
The first study to investigate the parenting experiences of older IVF mothers has revealed that they cope equally well with the stress of motherhood as those who have children in their 30s and 40s and are no more likely to suffer physical or psychological ill health.
The US findings come just a week after experts in Britain argued that maternal age should not be a sufficient reason to refuse IVF treatment. Doctors should instead be left to choose patients according to their own clinical judgment, the British experts argued.
Controversy surrounding the issue of older mothers centres on the likely effects on their physical and mental health and that of their children. Older women, particularly those over 55, have a higher risk of pregnancy complications such as pre-eclampsia and many people question their capacity to care for their children as they grow old themselves. The new research from the University of Southern California indicates that at least some of these concerns are misplaced.
"There is reason to say, in the absence of other data, that maybe we shouldn't jump to the conclusion that it's wrong for women to become mothers at this age," said Anne Steiner, who conducted the work with colleague Richard Paulson.
In the study, which will be presented today at the American Society for Reproductive Medicine conference in New Orleans, the researchers investigated 49 women who had given birth at 50 or over between 1992 and 2004, after treatment with donated eggs at the USC clinic.
Each was matched with an IVF mother in her 30s and another in her 40s and all were sent questionnaires. The results showed no significant differences between the three groups on any of these measures. The oldest mothers suffered slightly fewer psychological problems than younger ones.
"If we look from the perspective of stress and physical and mental functioning, it doesn't seem like we can restrict parenting based on these reasons," Dr Steiner said.
Older women in the study tended to have younger partners and this may influence their ability to cope, she said.
Dr Paulson said opposition to older mothers rested not on evidence, but on prejudice.

一项新研究的结果显示，50多岁生育的女性与生育时远比她们年轻的女性相比，在身体和心理上同样健康，这对生育年龄的上限提出了强有力的质疑。
这项首次对大龄体外受精母亲的亲职经验进行的研究发现，她们与30多岁或者40多岁生育的妇女一样，可以很好的处理作为母亲这一角色所带来的焦虑，并没有因此而受到身体或者心理疾病的困扰。
在该研究的结果发表1周前，英国的专家声称，母亲的年龄并不是拒绝为其进行体外受精的充分理由，相反，医生应该根据他们的临床经验对病人进行选择。
对于大龄母亲问题的争论主要集中在是否会影响母亲及孩子的身心健康。大龄母亲，尤其是55岁以上的大龄母亲，发生子痫前症等孕期综合症的危险增加，随着她们自己逐渐变老，许多人对她们照顾孩子的能力表示怀疑。这项美国南加州的研究显示，这些顾虑中至少有一部分是没必要的。
Anne Steiner和他的同事Richard Paulson共同指导了这项研究，她表示，目前在没有其他数据的情况下，我们有理由相信，武断的认为这个年龄的女性进行生育是错误的是不对的。
这项研究的结果将在美国生殖医学学会上公布。研究者选择了1992-2004年间在南加州大学医学中心进行体外受精的49名50岁或50岁以上女性进行观察研究。给这些大龄母亲分别配对一个30多岁和一个40多岁的IVF母亲作为对照。对所有研究对象进行问卷式调查。结果显示，3组研究对象的各项指标均无显著差异。年龄最大的母亲与年轻母亲相比，较少出现心理问题。
Steine博士说，从应激、身体和心理的角度来看，我们没有理由对女性甚于年龄做出限制。
