意大利一项研究证实。高龄爸爸的子女早产的危险较高,如果再加上妈妈的年纪较轻的话,妊娠32周以前早产的危险更高。专家认为父母年龄落差大可能是导致早产的一个危险因素。研究人员分析资料后发现。在妊娠37周以前早产的危险和爸爸的年龄成正比。对20～24岁之间的妈妈而言,高龄爸爸的影响又大于对25～29岁的妈妈的影响。举例而言,爸爸的年龄是45～49岁,若妈妈的年龄在20～24岁之间,那么早产的危险会是25～29岁妈妈的两倍。帕维亚大学的艾丝托菲和同事在《流行病 A study in Italy confirmed. Older dad’s children have a higher risk of preterm delivery and, if coupled with younger moms, have a higher risk of preterm birth by 32 weeks of gestation. Experts believe that a big gap in parents’ age may be a risk factor for preterm birth. Researchers analyzed the data found. The risk of preterm birth at 37 weeks of gestation is directly proportional to the age of dad. For mothers between the ages of 20 and 24, older dads have greater impact than mothers aged 25-29. For example, my father’s age is 45 to 49 years old. If the mother’s age is between 20 and 24 years old, then the risk of premature delivery will be twice that of 25-29-year-old mother.
