A cohort study comparing risks of morbidity at the time of elective abortion between 399 young adolescents aged 17 years or less matched to 399 women aged 20 to 29 years was completed. The study matched for duration of gestation, types of procedure, parity, race, month of procedure, and insurance status. Results indicated a relative risk of post-abortal endometritis for adolescents compared to older women of 2.5 (95% C.L. 1.48, 3.85). The reasons for this difference are unclear.
一项队列研究完成，该研究比较了399名17岁及以下的年轻青少年与399名20至29岁女性在选择性流产时的发病风险。该研究在妊娠持续时间、手术类型、产次、种族、手术月份和保险状况方面进行了匹配。结果表明，与年龄较大的女性相比，青少年流产后子宫内膜炎的相对风险为2.5（95%置信区间1.48, 3.85）。这种差异的原因尚不清楚。
