Sexual attraction (SA), the earliest stage of sexual orientation, is scarcely studied. This prospective study examined, over 3 years, prevalence, changes in SA, and the role of context, among 946 Puerto Rican youth, aged 11-13 years at initial assessment in the South Bronx (SBx), New York City, and Puerto Rico (PR). Overall, 98.1% of boys and 95.3% of girls reported opposite-sex only SA at some point, whereas 13.8% of girls and 12.0% of boys reported any-same SA. Opposite-sex only SA increased over time, whereas other SAs decreased except for any same-sex SA among SBx girls. Girls in the SBx and younger youth in PR reported more any same-sex SA. Context and culture may play a role in the developmental trajectories of adolescents' SA.
性吸引（SA）是性取向的最早阶段，几乎没有研究。本前瞻性研究在 3 年内，对来自波多黎各的 946 名 11-13 岁青少年进行了调查，这些青少年最初在纽约市南布朗克斯（SBx）和波多黎各（PR）接受评估。总的来说，98.1%的男孩和 95.3%的女孩在某个时候只报告了异性性吸引，而 13.8%的女孩和 12.0%的男孩报告了任何同性性吸引。异性性吸引随着时间的推移而增加，而其他性吸引则减少，除了 SBx 女孩中的任何同性性吸引。SBx 的女孩和 PR 年龄较小的青少年报告的任何同性性吸引更多。背景和文化可能在青少年性吸引的发展轨迹中发挥作用。
