关于这个话题我们已经知道了什么？ 从2007年到2014年，美国的青少年出生率和早产率下降。早产在最年轻和最年长的母亲中更为常见。这份报告补充了什么？所有年龄组的早产率都有所下降，总体上从10.41%降至9.54%。母亲的平均年龄从27.4岁增加到28.3岁。青少年和20-24岁妇女的生育减少对早产总体下降的贡献被高龄母亲的生育增加所抵消。对公共卫生实践的影响是什么？进一步降低早产率的有效公共卫生战略需要适合不同年龄组。
What is already known about this topic? Rates of births to teens and of preterm births declined in the United States from 2007 to 2014. Preterm births are more common among the youngest and oldest mothers.What is added by this report?Preterm birth rates declined for all age groups and overall from 10.41% to 9.54% of live births. Mean maternal age increased from 27.4 years to 28.3 years. The contribution of fewer births to teens and to women aged 20-24 years to the overall decline in preterm births was offset by increases in births to older mothers.What are the implications for public health practiceThe changing distribution of maternal age might indicate success of programs to prevent teen and unintended pregnancies. Effective public health strategies for further reducing preterm birth rates need to be tailored to different age groups.
