Most interventions designed to reduce teen pregnancy rates have not focused on pregnant and/or parenting adolescents. Therefore, a large randomized controlled trial was conducted regarding a motivational interviewing program entitled Teen Options to Prevent Pregnancy in a low-income sample of adolescent mothers. This program recommended monthly sessions between a participant and a registered nurse over 18 months. This program also featured facilitated birth control access through transportation assistance and a part-time contraceptive clinic.
The impact of this program on rapid repeat pregnancies at 18 months after enrollment was evaluated.
Five hundred ninety-eight adolescent females were enrolled from 7 obstetrics-gynecology clinics and 5 postpartum units of a large hospital system in a Midwestern city. Each participant was enrolled at least 28 weeks pregnant or less than 9 weeks postpartum. Each participant was randomized to either the Teen Options to Prevent Pregnancy intervention or a usual-care control condition. Intervention participants averaged 4.5 hours of assistance. Participants were contacted by blinded research staff at 6 and 18 months to complete self-report surveys. Differences in outcomes between the intervention and control groups were assessed using ordinary least-squares regression.
There was an 18.1% absolute reduction in self-reported repeat pregnancy in the intervention group relative to the control group (20.5% vs 38.6%%; P < .001). There was a 13.7% absolute increase in self-reported long-acting reversible contraception use in the intervention group relative to the control group (40.2% vs 26.5%, P = .002). There was no evidence of harmful effects of the intervention on sexual risk behaviors, such as having sexual intercourse without a condom or greater number of partners.
The Teen Options to Prevent Pregnancy program represents one of the few evidence-based interventions to reduce rapid repeat teen pregnancy. This relatively brief intervention may be a viable alternative to more time-intensive programs that adolescent mothers may be unable or unwilling to receive.
大多数旨在降低青少年怀孕率的干预措施都未关注怀孕和/或育有子女的青少年。因此,针对一项名为“青少年预防怀孕选择”的动机性访谈项目,在低收入青少年母亲样本中开展了一项大型随机对照试验。该项目建议参与者与注册护士在18个月内每月进行一次会面。该项目还通过交通援助和兼职避孕诊所,为获取节育措施提供便利。
评估该项目对入组后18个月内快速再次怀孕的影响。
从美国中西部城市一家大型医院系统的7家妇产科诊所和5个产后病房招募了598名青春期女性。每位参与者在怀孕至少28周或产后少于9周时入组。每位参与者被随机分配到“青少年预防怀孕选择”干预组或常规护理对照组。干预组参与者平均获得4.5小时的帮助。在6个月和18个月时,由不知情的研究人员联系参与者,以完成自我报告调查。使用普通最小二乘法回归评估干预组和对照组之间结果的差异。
与对照组相比,干预组自我报告的再次怀孕率绝对降低了18.1%(20.5%对38.6%;P < 0.001)。与对照组相比,干预组自我报告的长效可逆避孕措施使用率绝对增加了13.7%(40.2%对26.5%,P = 0.002)。没有证据表明该干预措施对性行为风险行为有有害影响,如无避孕套性交或性伴侣增多。
“青少年预防怀孕选择”项目是少数基于证据的降低青少年快速再次怀孕的干预措施之一。这种相对简短的干预措施可能是青少年母亲可能无法或不愿接受的耗时更长项目的可行替代方案。
