Study Objective

To determine the association of postpartum contraceptive use with repeat deliveries among adolescents and youth.

Design

Retrospective, observational analysis of electronic health record data.

Setting

Single, urban facility in Denver, Colorado, United States.

Participants

Women aged 10-24 years who gave birth between January 1, 2011 and December 31, 2015.

Interventions and Main Outcome Measures

Postpartum contraceptive use and time to subsequent delivery.

Results

Among 4068 women, 1735 (43%) used postpartum contraception. In adjusted analyses, characteristics associated with contraceptive use included Hispanic ethnicity (relative risk [RR], 1.1; P = .03), incremental prenatal visits (RR, 1.01; P = .047), and attendance at postpartum care (RR, 1.60; P < .001). Long-acting reversible contraceptive (LARC) use was higher among women younger than 15 years (reference: 20-24 years; RR, 1.12; P < .001) and lower among women aged 18-19 years (RR, 0.93; P = .009). Hispanic women had higher rates of LARC use than non-Hispanic women (RR, 1.07; P = .02). Compared with inpatient LARC placement, outpatient placement (1-4 weeks and 5 or more weeks) rates were lower (RR, 0.77 and RR, 0.89, respectively; P < .001). Time to subsequent delivery was shorter in non-LARC users (median, 659 days) and contraception nonusers (median, 624 days) compared with LARC users (median, 790 days; P < .001); non-LARC postpartum contraceptive use did not significantly alter time to repeat delivery compared with that in women who used no method (P = .24).

Conclusion

Postpartum LARC use reduced the risk of repeat pregnancy with a significant increase in time to the next delivery. Non-LARC use was not different from no contraceptive use in terms of time to repeat delivery.

丹佛青少年和年轻人产后避孕药具的使用:与后续重复分娩的关联。

学习目的

确定产后避孕药具使用与青少年和青年重复分娩的关联。

设计

电子健康记录数据的回顾性观察分析。

环境

美国科罗拉多州丹佛市的单一城市设施。

参与者

2011年1月1日至2015年12月31日期间分娩的10-24岁女性。

干预措施和主要结果措施

产后避孕药具的使用和下次分娩的时间。

结果

在 4068 名妇女中,1735 名 (43%) 使用了产后避孕。在调整后的分析中,与避孕药具使用相关的特征包括西班牙裔种族(相对风险 [RR],1.1;P  = .03)、增加的产前检查(RR,1.01;P  = .047)和产后护理的出席率(RR,1.60 ; P  < .001)。15 岁以下女性的长效可逆避孕 (LARC) 使用率较高(参考:20-24 岁;RR,1.12;P  < .001),而 18-19 岁女性的使用率较低(RR,0.93;P  = .009)。西班牙裔女性的 LARC 使用率高于非西班牙裔女性(RR,1.07;P = .02)。与住院 LARC 安置相比,门诊安置(1-4 周和 5 周或更长时间)率较低(RR,分别为 0.77 和 RR,0.89;P  < .001)。与 LARC 使用者(中位数,790 天;P  < .001)相比,非 LARC 使用者(中位数,659 天)和未使用避孕措施(中位数,624 天)的后续分娩时间更短;与未使用任何避孕方法的女性相比,使用非 LARC 产后避孕药并没有显着改变重复分娩的时间(P  = .24)。

结论

产后 LARC 的使用降低了重复怀孕的风险,显着增加了下次分娩的时间。就重复分娩的时间而言,不使用 LARC 与不使用避孕药具没有区别。
