More Women Try to Get Pregnant With Medical Help
A growing share of American women are seeking medical help to become pregnant.
Data from the Centers for Disease Control & Prevention show that roughly 12.5% of women between the ages of 25 and 44 had sought such help--everything from counseling to artificial insemination--during the 2006-2010 survey period, up from 11.2% in 1995.
Among women 35 to 39 years old who have experienced one or more births, 15.8% got medical help, up from 13.1% in 1995. For women in this age group who have never had children, the share rose slightly to 19.6% from 19.1%.
The findings are part of the CDC's National Survey of Family Growth, which was conducted between June 2006 and June 2010. More than 12,000 women were interviewed, not all of whom had fertility problems or were seeking to get pregnant.
While the CDC survey is nationally representative, individual demographic percentages--for example, women in their late 30s who have had no children--may have a larger margin of error because they rely on smaller sample sizes. Also, the CDC's definition of 'medical help to get pregnant' is broad--ranging from getting advice and infertility testing to artificial insemination, which is fairly rare.
Women who are white, better-educated and wealthier are more likely to make use of infertility services, the CDC said.
Still, the agency's latest figures highlight the effects of one of America's biggest demographic trends: Young and middle-aged Americans are delaying childbearing, often until their 30s or mid-30s, or even beyond.
The average age of a U.S. mother at first birth rose to 25.8 years old in 2012, up from 25.6 years in 2011 and around 21 in 1970, CDC data show. Research has shown that improved access to contraception, growing numbers of women in the workforce and the higher costs of raising families are factors in women putting off having children. <纽约时报中英文网 http://www.qqenglish.com/>
Fertility generally declines in the 30s, according to the American Society for Reproductive Medicine.
While the percentage of women aged 30 to 34 receiving help to get pregnant rose just slightly to 11.1% from 10% in 1995, that may suggest women are trying to have children even later in their lives. The share of women 35 to 39 getting medical help for pregnancy rose to 16.4% from 14.3% in the earlier survey.
The CDC found that among women aged 25 to 44 who had fertility problems and had never had children, 38% had used infertility services, compared with 56% in 1982--a sizable drop.
But this 'may partly reflect the greater delays in childbearing over this time period, such that women in 2006-2010 were more likely to be older than women in 1982 when trying to have their first child, and also more likely to use services beyond age 44,' the CDC said.
Indeed, 23.4% of women aged 40 to 44 who have never had a child have sought medical help to get pregnant.
美国疾病控制和预防中心(Centers for Disease Control & Prevention)的数据显示，在2006-2010年的调查期间，25-44岁之间的女性大约有12.5%曾经寻求从咨询到人工授精更各类帮助，比例高于1995年的11.2%。
据美国生殖医学会(American Society for Reproductive Medicine)的数据，30多岁的女性生育能力普遍出现下降。
