福克斯新闻 新晋奶爸平均年龄推迟

We've known that women have been delaying motherhood, now there's also more data out on dads. The average age of newborns' fathers was nearly 31-years-old in 2015, up by almost four years since the 1970's, according to a study published in the Journal Human Reproduction. Researchers at Stanford University finding the number of newborns dads who are over 40 more than doubled over the past four decades, accounting¹ for about nine percent of all U.S. births.

A study's co-author says the trend existed for every race, ethnicity, education level and region of the country scientists looked at.

Doctor Michael Eisenberg also saying the findings could mean fewer childbearing years and smaller families with potentially large economic and public health impact.

我们已经知道很多女性推迟了生育的时间，这里还有一些关于奶爸们的数据。《人类生殖》杂志刊登的一项研究表示，2015年新晋奶爸的平均年龄差不多是31岁，相比七十年代推迟了将近4年。

斯坦福大学研究人员也发现，过去的40年里，新晋奶爸年龄在40岁以上的数目翻了一倍多。某项研究的联名作者还说，科学家们考察的多个种族、民族、教育阶层以及地区都表现出了这一趋势。

迈克·埃森博格博士还说，这些发现可能意味着子女数目的减少，家庭规模的缩减，还可能带来较大的经济和公共卫生影响。
