To compare changes over time in prevalence of school victimization among lesbian, gay, and bisexual (LGB) students compared with heterosexual students.
We analyzed data from 11 Youth Risk Behavior Surveys conducted among representative samples of students in grades 9 through 12 in Massachusetts during 1995 to 2015. We used multivariable logistic regression models to identify trends over time by sexual identity.
During 1995 to 2015, the prevalence of missing school decreased overall (from 5.6% to 4.8%) and among heterosexual (from 4.3% to 3.8%) and LGB (from 25.0% to 13.4%) students. The prevalence of having been threatened decreased overall (from 7.8% to 4.1%) and among heterosexual (from 6.5% to 3.5%) and LGB (from 32.9% to 6.7%) students.
We identified evidence of a significant decrease in victimization among all students regardless of sexual identity and a steep decline among LGB students. Additional actions to improve school climate may help eliminate the disparities and decrease victimization for all youths.
比较女同性恋、男同性恋和双性恋（LGB）学生与异性恋学生在校园受侵害率随时间的变化情况。
我们分析了1995年至2015年期间在马萨诸塞州对9至12年级学生代表性样本进行的11次青少年风险行为调查的数据。我们使用多变量逻辑回归模型按性取向确定随时间的趋势。
1995年至2015年期间，缺课率总体下降（从5.6%降至4.8%），异性恋学生中（从4.3%降至3.8%）以及LGB学生中（从25.0%降至13.4%）均如此。受到威胁的发生率总体下降（从7.8%降至4.1%），异性恋学生中（从6.5%降至3.5%）以及LGB学生中（从32.9%降至6.7%）也是如此。
我们发现证据表明，无论性取向如何，所有学生受侵害情况均显著减少，LGB学生受侵害情况急剧下降。采取更多行动改善校园氛围可能有助于消除差距并减少所有青少年受侵害的情况。
