This study evaluated a mentoring program designed to decrease the risk of repeat pregnancy among unmarried primiparous teens, ages 12-19.
Adolescents (n = 110) completed a battery that assessed sexual/contraceptive behavior; psychological adjustment; and attitudes towards school. Teens were then randomly assigned to a mentor or control group, and reassessed at 6, 12, 18, and 24 months. Mentored teens received social support and assistance dealing with community agencies from mentors who were trained community volunteers.
At baseline, mentor and control teens had similar sexual histories, school achievement profiles (percentage enrolled, cumulative grade point average), and anticipated being the same age when they had a second child. At 24 months (n = 81), most mentor and control teens were making progress in school. Fifty percent had graduated or had advanced two grades; 10 of the 16 graduating teens were seeking additional education. However, the mentoring program did not significantly impact repeat pregnancy rates. At 33 months, 66.0% of the mentored teens and 68.8% of the control teens had experienced a repeat pregnancy. Thirty-six percent of teens had one repeat pregnancy; 24% had two or more pregnancies. Sixty-two percent of the pregnancies with known resolution (89) resulted in live births; 26% were aborted. In providing this mentoring program, several important lessons were learned.
本研究评估了一项旨在降低12至19岁未婚初产青少年再次怀孕风险的指导计划。
青少年(n = 110)完成了一系列评估性/避孕行为、心理调适以及对学校态度的测试。然后,青少年被随机分配到指导组或对照组,并在6个月、12个月、18个月和24个月时进行重新评估。接受指导的青少年从经过培训的社区志愿者导师那里获得社会支持以及与社区机构打交道的协助。
在基线时,指导组和对照组青少年的性史、学业成绩概况(入学百分比、累积平均绩点)相似,并且预计生育第二个孩子时年龄相同。在24个月时(n = 81),大多数指导组和对照组青少年在学业上都取得了进步。50%的人已经毕业或跳了两级;16名毕业青少年中有10人正在寻求进一步的教育。然而,指导计划对再次怀孕率没有显著影响。在33个月时,66.0%的受指导青少年和68.8%的对照组青少年经历了再次怀孕。36%的青少年有过一次再次怀孕;24%的青少年有过两次或更多次怀孕。已知结局的怀孕案例(89例)中有62%以活产告终;26%的案例流产。在实施这项指导计划的过程中,我们吸取了几个重要的教训。
