Children fathered by older men are likely to be less intelligent than the offspring of younger dads, Australian and US scientists have found in a report published yesterday.

The surprise result contrasted sharply with earlier studies showing that older mothers produced children more likely to record above average intelligence scores, the researchers concluded.

Lead scientist John McGrath, from the Queensland Brain Institute, said the result was a world first and had implications for men in Western societies who have delayed fatherhood until their 40s or older.

"The results were quite startling as it was thought that the age of the father was less of a concern compared to the age of the mother," McGrath said. "Now we are getting more evidence of the age of the father being just as important - the older a dad is, the worse his children tend to do in intelligence tests."

Researchers examined data collected on 33,000 children in the US between 1959 and 1965 fathered by men aged from 15 to 65. They found that the children of older dads performed less well in intelligence tests conducted at age eight months, four years and seven years.

The researchers said previous studies had linked older fathers to an increased risk of health problems in their children, including schizophrenia, autism, dyslexia, epilepsy and dwarfism.

However, the study published in the journal Public Library of Science Medicine is the first to suggest there is also a link with general intelligence.

The trend towards children of older fathers being less intelligent remained statistically significant even when factors such as socio-economic status and parental mental health were taken into account.

McGrath said the research team could not draw conclusions on how having an older father impacted on children later in life because the subjects in their study were only examined until they were aged seven.

"It is feasible that the offspring of older fathers 'catch up' during later childhood," the researcher said.

"How the subtle neurocognitive features associated with (older fathers) translate into later educational and mental health outcomes across the lifespan remains to be determined."

Children fathered by older men are likely to be less intelligent than the offspring of younger dads, Australian and US scientists have found in a report published yesterday
澳大利亚和美国的研究人员在昨天发表的一份报告中指出：那些出生时父亲年龄较大的孩子不及父亲年龄小的孩子来的聪明。

The surprise result contrasted sharply with earlier studies showing that older mothers produced children more likely to record above average intelligence scores, the researchers concluded.
这个惊人的结果与早些时候的一项研究形成了反差，当时的研究人员总结说大年龄的母亲生出的孩子更有可能在智力评分上得到高于平均水平的分数。

Lead scientist John McGrath, from the Queensland Brain Institute, said the result was a world first and had implications for men in Western societies who have delayed fatherhood until their 40s or older.
该研究的首席科学家、来自昆士兰闹研究所的John McGrath说这个结果是世界上首个并且是能对西方社会的那些推迟做父亲年龄直到40多岁及以后的男性有暗示作用的。

"The results were quite startling as it was thought that the age of the father was less of a concern compared to the age of the mother," McGrath said. "Now we are getting more evidence of the age of the father being just as important - the older a dad is, the worse his children tend to do in intelligence tests."
“这个结果是非常令人惊讶的，因为过去认为与母亲的年龄相比父亲的年龄与孩子智力的相关性更小”McGrath说道，“现在我们有更多的证据表明父亲的年龄也是一样重要的——父亲年龄越是大，他的孩子在智力测试上的得分趋向于越低。”

Researchers examined data collected on 33,000 children in the US between 1959 and 1965 fathered by men aged from 15 to 65. They found that the children of older dads performed less well in intelligence tests conducted at age eight months, four years and seven years.
研究人员分析了美国1959年到1965年间出生，出生时父亲的年龄从15到65岁不等的33，000个孩子的数据。他们发现年长父亲的孩子在其8个月、四岁、七岁时进行的智力测试中的表现略逊一筹。

The researchers said previous studies had linked older fathers to an increased risk of health problems in their children, including schizophrenia, autism, dyslexia, epilepsy and dwarfism.
研究人员说以前的研究已经表明年长的父亲在孩子的健康问题比如精神分裂症、自闭症、阅读障碍、癫痫、侏儒症上的风险增高有关。

However, the study published in the journal Public Library of Science Medicine is the first to suggest there is also a link with general intelligence.
然而，这项刊登在《公共科学图书馆·医学》上的研究结果是第一个提示父亲年龄与孩子的普通智力有关。

The trend towards children of older fathers being less intelligent remained statistically significant even when factors such as socio-economic status and parental mental health were taken into account.
即便我们将诸如社会经济地位和双亲心理健康这样的因素纳入统计范围，父亲年龄越大的孩子越不聪明的趋势仍然有统计学意义。

McGrath said the research team could not draw conclusions on how having an older father impacted on children later in life because the subjects in their study were only examined until they were aged seven.
McGrath说研究队伍不能就在将来的生活中有一个年长的父亲有什么影响做出结论，因为对他们项目中的研究对象的智力测试只持续到他们7岁。

"It is feasible that the offspring of older fathers 'catch up' during later childhood," the researcher said.
研究人员说：“年长父亲的后代可以在将来的孩童时代追赶上来，这一点是行得通的.”

"How the subtle neurocognitive features associated with (older fathers) translate into later educational and mental health outcomes across the lifespan remains to be determined."
“敏感的神经系统的识别与父亲年长有关，这个特点如何转变为在将来生命过程中的迥异的教育及心理健康状况，仍然有待论证。”
