We examined associations between sexual orientation and pregnancy risk among sexually experienced New York City high-school students.
We analyzed data from 2005, 2007, and 2009 New York City Youth Risk Behavior Surveys. We excluded students who had never engaged in sexual intercourse, only had same-gender sexual partners, or had missing data on variables of interest, resulting in a final sample of 4892 female and 4811 male students. We employed multivariable logistic regression to examine pregnancy risk by sexual orientation, measured as self-reported sexual identity and gender of sexual partners, with adjustment for demographics and sexual behaviors. We stratified analyses by gender.
Overall, 14.3% of female and 10.8% of male students had experienced a pregnancy. Students who identified as gay, lesbian, or bisexual or reported both male and female sexual partners had higher odds of pregnancy than heterosexual students or students who only had opposite-gender sexual partners. Sexual behaviors accounted for higher odds of pregnancy among female, but only partially accounted for higher odds of pregnancy involvement among male, sexual-minority students.
Sexual orientation should be considered in future adolescent pregnancy-prevention efforts, including the design of pregnancy-prevention interventions.
我们研究了有性经历的纽约市高中生的性取向与怀孕风险之间的关联。
我们分析了2005年、2007年和2009年纽约市青少年风险行为调查的数据。我们排除了从未有过性交经历、只有同性性伴侣或在感兴趣变量上有缺失数据的学生，最终样本为4892名女生和4811名男生。我们采用多变量逻辑回归，通过性取向（以自我报告的性身份和性伴侣性别衡量）来研究怀孕风险，并对人口统计学和性行为进行了调整。我们按性别分层分析。
总体而言，14.3%的女生和10.8%的男生有过怀孕经历。自我认同为同性恋、双性恋或报告有男性和女性性伴侣的学生比异性恋学生或只有异性性伴侣的学生怀孕几率更高。性行为在女生中占怀孕几率较高的比例，但在男性性少数群体学生中，性行为只是部分解释了较高的怀孕几率。
在未来的青少年怀孕预防工作中，包括怀孕预防干预措施的设计中，应考虑性取向因素。
