To discuss changes in female demographic parameters in the US and associated increase in utilization of fertility services.
Fractions of women earning bachelor's, master's, and doctoral degrees increased from 1970 to 2018 (32.6 vs 64.8; 7.9 vs 27.3; 0.54 vs 5.7 per 10,000 women; P < .001; respectively). This was associated with decrease in percentage of married women (61.9% vs 50.8%) and increase in median age at first marriage (20.8 vs 27.8). In parallel, mean age of mothers at first birth increased (21.4 vs 26.8), and pregnancy rates of women aged 35-39 and 40-44 years doubled between 1980 and 2010 (0.036 vs 0.077; 0.009 vs 0.019 per 1,000 women). With later pregnancy attempts, female fertility rates decreased from 1970 to 2017 (87.9% vs 60.3%; P < .001). Women undergoing assisted reproductive technologies (ART) treatment with a DOR diagnosis increased (12% vs 31%), and ART cycles using donor eggs increased (16,161 vs 24,300), between 2005 and 2016.
Participation of women in education is paralleled by increased female employment, later occurrence of marriage, increased age of childbearing, decreased fertility rates, and increased DOR diagnosis.
讨论美国女性人口统计学参数的变化以及由此导致的生育服务利用率的增加。
1970 年至 2018 年,获得学士、硕士和博士学位的女性比例有所增加(分别为 32.6%比 64.8%、7.9%比 27.3%、0.54%比 5.7%,每 10000 名女性中分别增加;P<0.001)。这与已婚女性的比例下降(61.9%比 50.8%)和初婚年龄中位数增加(20.8 比 27.8)有关。与此同时,初产妇的平均年龄增加(21.4 比 26.8),1980 年至 2010 年,35-39 岁和 40-44 岁女性的怀孕率增加了一倍(分别为 0.036 比 0.077、0.009 比 0.019,每 1000 名女性)。随着怀孕尝试的推迟,女性生育率从 1970 年至 2017 年下降(87.9%比 60.3%;P<0.001)。接受 DOR 诊断的辅助生殖技术(ART)治疗的女性人数增加(12%比 31%),并且 2005 年至 2016 年,使用供卵的 ART 周期增加(16161 比 24300)。
女性参与教育与女性就业增加、婚姻推迟、生育年龄增加、生育率下降以及 DOR 诊断增加同时发生。
