Many studies have examined differences in sexual behavior based on sexual orientation with results often indicating that those with same-sex partners engage in higher risk sexual behavior than people with opposite sex partners. However, few of these studies were large, national sample studies that also include those identifying as unsure. To address that gap, this study examined the relationship of sexual orientation and sexual health outcomes in a national sample of U.S. college students. The Fall 2009 American College Health Association-National College Health Assessment was used to examine sexual health related responses from heterosexual, gay, lesbian, bisexual, and unsure students (N = 25,553). Responses related to sexual behavior, safer sex behaviors, prevention and screening behaviors, and diagnosis of sexual health related conditions were examined. The findings indicated that sexual orientation was significantly associated with engaging in sexual behavior in the last 30 days. Sexual orientation was also significantly associated with the number of sexual partners in the previous 12 months, with unsure men having significantly more partners than gay, bisexual and heterosexual men and heterosexual men having significantly less partners than gay, bisexual and unsure men. Bisexual women had significantly more partners than females reporting other sexual orientations. Results examining the associations between sexual orientation and safer sex, prevention behaviors, and screening behaviors were mixed. Implications for practice, including specific programmatic ideas, were discussed.
许多研究都考察了基于性取向的性行为差异，结果往往表明，与异性伴侣的人相比，有同性伴侣的人会进行更高风险的性行为。然而，这些研究中很少有大规模的全国性样本研究，也没有将那些身份不确定的人纳入其中。为了填补这一空白，本研究在美国大学生的全国性样本中考察了性取向与性健康结果之间的关系。2009年秋季的美国大学健康协会-全国大学生健康评估被用于考察异性恋、男同性恋、女同性恋、双性恋以及身份不确定的学生（N = 25,553）与性健康相关的回答。研究了与性行为、安全性行为、预防和筛查行为以及性健康相关疾病诊断有关的回答。研究结果表明，性取向与过去30天内进行性行为显著相关。性取向也与过去12个月内的性伴侣数量显著相关，身份不确定的男性比男同性恋、双性恋和异性恋男性有显著更多的伴侣，而异性恋男性比男同性恋、双性恋和身份不确定的男性有显著更少的伴侣。双性恋女性比报告其他性取向的女性有显著更多的伴侣。考察性取向与安全性行为、预防行为和筛查行为之间关联的结果喜忧参半。讨论了对实践的启示，包括具体的项目思路。
