Better knowledge about contraceptive use in adolescents is needed if pregnancy prevention is to be improved. Data from the 1979 National Survey of Young Women were used to examine method switching once contraceptive use had begun among 449 never-pregnant young women who reported premarital intercourse more than once. Bivariate chi2 tests and multivariate logit regression were used to examine factors related to switching in four analyses: overall switching; switching among those with one intercourse partner; and switching from nonmedical and medical methods separately. Frequency of intercourse and type of first method had an interactive effect on switching; length of exposure to switching, type of relationship, and reason for choosing the first method were also significant. These results suggest that providers and educators should consider the circumstances under which contraceptive methods are chosen and used by young women when counseling them as to what method may be best for them.
如果要更好地预防青少年怀孕,就需要更深入了解青少年使用避孕措施的情况。利用1979年全国年轻女性调查的数据,对449名从未怀孕且报告有多次婚前性行为的年轻女性开始使用避孕措施后的方法转换情况进行了研究。在四项分析中,采用双变量卡方检验和多变量逻辑回归来研究与转换相关的因素:总体转换情况;有一个性伴侣的人群中的转换情况;以及分别从不医学方法和医学方法转换的情况。性行为频率和首次使用方法的类型对转换有交互作用;使用方法的时长、关系类型以及选择第一种方法的原因也具有显著性。这些结果表明,在为年轻女性提供咨询,告知她们哪种方法可能最适合她们时,提供者和教育者应考虑年轻女性选择和使用避孕方法的具体情况。
