This study utilizes a data set combining vital records from live birth and induced abortion certificates in New York City in 1984 to examine the correlates of the two outcomes among pregnant adolescents. Four groups totaling 31,207 teenagers were examined: Black non-Latinos (51 per cent), White non-Latinos (17 per cent), Puerto Ricans (25 per cent), and non-Puerto Rican Latinos (8 per cent). Multivariate regressions were fit for each group. Simulations based on the regressions reveal that the proportion of live births plus induced abortions among unmarried 18-year-olds, on Medicaid, with a previous live birth, no previous induced abortions, and nine years of completed schooling was .55 in the case of Puerto Ricans, .34 for non-Puerto Rican Latinos, .60 for Blacks, and .51 for Whites. For nulliparous adolescents of the same age and marital status, with an additional year of schooling, but not on Medicaid, and with a previous induced abortion, the fraction of pregnancies that were terminated rose to .84 in the case of Puerto Ricans, .81 for non-Puerto Rican Latinos, .87 for Blacks, and .96 for Whites. The results suggest that attitudes toward abortion as proxied by previous induced terminations substantially increase the likelihood of aborting as well as narrow the racial and ethnic differences with respect to pregnancy resolution.
本研究利用了一个数据集,该数据集结合了1984年纽约市活产和人工流产证明中的生命记录,以研究怀孕青少年中这两种结果的相关因素。共对四组总计31207名青少年进行了调查:黑人非拉丁裔(51%)、白人非拉丁裔(17%)、波多黎各人(25%)和非波多黎各拉丁裔(8%)。对每组进行了多变量回归分析。基于这些回归分析的模拟结果显示,对于未婚的18岁青少年,享受医疗补助、有过一次活产、无人工流产史且完成九年学业的情况,波多黎各人的活产加人工流产比例为0.55,非波多黎各拉丁裔为0.34,黑人为0.60,白人为0.51。对于年龄和婚姻状况相同、多接受一年教育、未享受医疗补助且有过一次人工流产史的未生育青少年,波多黎各人终止妊娠的比例升至0.84,非波多黎各拉丁裔为0.81,黑人为为0.87,白人为0.96。结果表明,以前人工流产所代表的对堕胎的态度大幅增加了堕胎的可能性,同时也缩小了在妊娠结局方面的种族和族裔差异。
