目的：虽然先前的研究已经阐明了青少年快速重复妊娠的一些危险因素，但我们试图根据重复妊娠的强度来评估既有和假设的危险因素。方法：研究人群来自2002年全国家庭成长调查(NSFG)，包括在青少年时期经历过至少一次怀孕的女性，在怀孕解决后至少24个月接受了采访，在NSFG访谈时年龄在30岁及以下。为了评估各种预测变量对快速重复妊娠强度的影响，我们构建了一个多分类多因素Logistic回归模型。结果：在2002年的NSFG中，34%的经历过快速重复妊娠的青少年报告了这样的怀孕意向。尽管第一次怀孕时年龄较小(或=15岁)与意外快速重复怀孕的可能性降低有关，但种族/民族特征以及青少年母亲的特征(青少年第一次出生时母亲的教育程度和年轻年龄)与有意或意外快速重复怀孕无关。与预期再次怀孕的可能性增加相关的因素包括预期的第一次怀孕、既往不良的产科结果以及青少年的伴侣有意再次怀孕。在第二次怀孕时结婚与意外快速重复怀孕的可能性降低有关。结论：考虑青少年重复怀孕的强度可能有助于制定更适当和更有效的计划生育干预措施。
PURPOSE: Whereas previous research has elucidated a number of risk factors for rapid repeat pregnancies among adolescents, we sought to assess both established and hypothetical risk factors in the context of the intendedness of the repeat pregnancy.METHODS: The study population, drawn from the 2002 National Survey of Family Growth (NSFG), consisting of women who experienced at least one pregnancy as an adolescent, were interviewed at least 24 months since that pregnancy's resolution and were aged 30 years and younger at the time of the NSFG interview. To evaluate the effect of various predictor variables on the intendedness of a rapid repeat pregnancy, we constructed a polytomous multiple logistic regression model. Outcomes are reported as ratios of odds ratios (ROR) and were calculated using women experiencing an adolescent pregnancy, but not a rapid repeat pregnancy, as the reference group.RESULTS: In the 2002 NSFG, 34% of the adolescents experiencing a rapid repeat pregnancy reported such pregnancies to be intended. Although young age (< or = 15 years) at first conception was associated with a decreased likelihood of an unintended rapid repeat pregnancy, racial/ethnic characteristics as well as characteristics of the teen's mother (educational status and young age of the teen's mother at first birth) were not associated with either intended or unintended rapid repeat pregnancies. Factors found to be associated with an increased likelihood of having an intended repeat pregnancy included an intended first pregnancy, prior poor obstetrical outcome, and having the repeat pregnancy intended by the teen's partner. Being married at the time of second conception was associated with a decreased likelihood of an unintended rapid repeat pregnancy.CONCLUSIONS: Consideration of the intendedness of repeat pregnancies among teenagers could help create more appropriate and effective family planning interventions.
