许多性少数女性，无论性别身份如何，在整个生命过程中都从事异性恋行为，这为她们提供了意外怀孕的机会。此外，性少数女性比其他人更有可能报告可能使她们容易意外怀孕的特征。然而，很少有研究调查这些女性意外怀孕的风险是否会增加。利用2006-2010年全国家庭成长调查的数据，采用逻辑回归和混合效应风险模型，对9807名20-45岁女性和5238名怀孕女性的不合时宜和意外怀孕中的性取向差异进行了检验。与只报告男性伴侣的异性恋女性相比，与女性发生性行为的异性恋女性报告不合时宜怀孕的几率更高（比值比为1.4），双性恋女性报告意外怀孕的几率更高（比值比为1.8）。与只有男性伴侣的异性恋女性报告的怀孕相比，与女性发生性行为的异性恋女性报告的怀孕更有可能是不合时宜的（风险比，1.7），而双性恋和女同性恋女性报告的怀孕更有可能是不想要的（1.7 - 4.4）。与只与男性发生性关系的异性恋者相比，成年性少数女性报告意外怀孕的风险相等或更大。需要对性少数群体妇女的生殖保健需求进行更多的研究，以制定战略，改善这一人口的计划生育。
Many sexual minority women, regardless of sexual identity, engage in heterosexual behavior across the life course, which provides them opportunities to experience an unintended pregnancy. In addition, sexual minority women are more likely than others to report characteristics that may make them vulnerable to unintended pregnancy. Little research, however, has examined whether the risk of unintended pregnancy is elevated among these women. Using data from the 2006–2010 National Survey of Family Growth, logistic regression and mixed-effects hazard models were fitted to examine sexual orientation disparities in mistimed and unwanted pregnancies among 9,807 women aged 20–45 and 5,238 pregnancies. Compared with heterosexual women reporting only male partners, heterosexual women who have sex with women had higher odds of reporting a mistimed pregnancy (odds ratio, 1.4), and bisexual women had higher odds of reporting an unwanted pregnancy (1.8). When compared with pregnancies reported by heterosexual women with only male partners, those reported by heterosexual women who have sex with women were more likely to be mistimed (hazard ratio, 1.7), and those reported by bisexual and lesbian women were more likely to be unwanted (1.7–4.4). Compared with heterosexuals who only have sex with men, adult sexual minority women are at equal or greater risk of reporting an unintended pregnancy. More research addressing the reproductive health care needs of sexual minority women is needed to develop strategies to improve family planning for this population.
