To describe patterns and changes in contraceptive use among pregnant adolescents in early and later postpartum compared with nonpregnant adolescents.
One-hundred-seventy-six pregnant and 187 nonpregnant adolescents, recruited through community clinics, were interviewed three times (baseline, 6-month follow-up, 12-month follow-up) about their condom and hormonal contraceptive practices. Changes in contraception use and patterns of consistent hormonal and/or condom use were examined. Statistical analyses included General Estimating Equations (GEE) and multinomial regression.
Pregnant adolescents increased hormonal contraceptive use from baseline to early postpartum, but decreased use from early postpartum to late postpartum. Nonpregnant adolescents did not change their hormonal contraceptive use over time. Neither group changed condom use over time. Pregnant adolescents were more likely to be consistent dual users and hormonal-only users during the 6-month follow-up compared with nonpregnant adolescents. These findings persisted at the 12-month follow-up, although there was a decline in hormonal contraception use.
Adolescents change their contraceptive use during the postpartum period. Given the slight decline in contraceptive use in late postpartum in this sample, more work is necessary to maintain motivation to continue these positive postpartum trends.
描述与未怀孕青少年相比,怀孕青少年在产后早期和晚期避孕措施的使用模式及变化。
通过社区诊所招募了176名怀孕青少年和187名未怀孕青少年,对他们进行了三次访谈(基线、6个月随访、12个月随访),询问他们使用避孕套和激素避孕措施的情况。研究了避孕措施使用的变化以及持续使用激素和/或避孕套的模式。统计分析包括广义估计方程(GEE)和多项回归。
怀孕青少年从基线到产后早期激素避孕措施的使用增加,但从产后早期到产后晚期使用减少。未怀孕青少年随着时间推移激素避孕措施的使用没有变化。两组随着时间推移避孕套的使用均未改变。与未怀孕青少年相比,怀孕青少年在6个月随访期间更有可能持续同时使用两种避孕措施和仅使用激素避孕措施。这些发现在12个月随访时仍然存在,但激素避孕措施的使用有所下降。
青少年在产后期间会改变他们的避孕措施使用情况。鉴于该样本中产后晚期避孕措施的使用略有下降,需要做更多工作来维持继续这些积极产后趋势的动力。
