背景：人们对少女怀孕这一复杂问题和减少青少年怀孕的方案给予了大量关注。方法：采用前后测对照设计，分析综合多元学校和社区干预对估计怀孕率和出生率的影响。结果：在干预期间，三个社区都有较高水平的计划活动，包括教师培训和对学生的性教育。调查受访者高度评价这样的项目干预措施，如延长与学校挂钩的诊所时间，以适应学生的时间表和在中学建立的支持小组。1994至1997年间，盖里县所有九年级和十年级学生中，青少年报告他们发生过性行为的比例显著下降，女性从51%下降到38%，男性从63%下降到43%。在富兰克林县，1996年一年级和十二年级的男性报告使用避孕套的人数(55%)比1994年(39%)多。在干预期间，富兰克林县和盖里县的首次性行为年龄保持相对稳定。在盖里县，14-17岁青少年的估计怀孕率在1994年至1997年期间有所下降，而在对照地区则有所上升。在富兰克林县和IFS比较社区中，14-17岁青少年的估计怀孕率都有所下降。在同一时期，威奇托市的一个目标地区和对照地区1991-1993-1994-1996的出生率均有所下降，但在威奇托的第二个目标地区的出生率上升，而在对照社区的出生率下降。结论：对青少年妊娠综合预防方案的评价有助于我们理解这一模式及其在不同社区的可推广性。正在进行的计划评估对于制定计划和完善战略以适应当地情况非常重要。
Context: A significant amount of attention has been devoted to the complex issue of teenage pregnancy and to programs for reducing pregnancy among adolescents. Careful evaluations of such programs are needed to ascertain what strategies will be most effective at reducing teenage pregnancy.Methods: A pretest-posttest comparison group design was used to analyze the effects of a comprehensive multicomponent school and community intervention on estimated pregnancy rates and birthrates among young people in three Kansas communities: Geary County Franklin County and selected neighborhoods of Wichita.Results: There were high levels of program activity in all three communities during the intervention period, including teacher training and sexuality education for students. Survey respondents rated highly such project interventions as the extension of school-linked clinic hours to accommodate student schedules and support groups established in middle schools. Between 1994 and 1997 the proportions of adolescents reporting that they had ever had sex decreased significantly among all ninth and 10th graders in Geary County, from 51% to 38% among females and from 63% to 43% among males. In Franklin County, more males in grades I I and 12 reported using condoms in 1996 (55%) than had done so in 1994 (39%). Age at first intercourse remained relatively stable in Franklin and Geary counties during the intervention period. The estimated pregnancy rate among adolescents aged 14-17 decreased between 1994 and 1997 in Geary Country, while it increased in comparison areas. The estimated pregnancy rates among 14-17-year-olds decreased in both Franklin County and ifs comparison communities. The birthrate declined both in one target area of Wichita and in ifs comparison area from 1991-1993 to 1994-1996 Over the same time period, the birthrate increased in a second target area of Wichita, while if decreased in the comparison communityConclusions: This evaluation of a comprehensive multicomponent program for adolescent pregnancy prevention contributes to our understanding of this model and its replicability in diverse communities. Ongoing program evaluation is important for developing initiatives and for refining strategies so they respond to local conditions.
