Note. CI = confidence interval; PSO = perceived sexual orientation; YQOL–HYS = Youth Quality of Life–Healthy Youth Survey. QOL was modeled with survey weighted linear regression; depressed mood and considered suicide were modeled with survey weighted logistic regression. All models were adjusted for the complex survey design and controlled for race/ethnicity and maternal education. In all models, the difference in the estimates for bullied because of PSO and bullied for other reasons is statistically significant (P < .05). All estimates of bullied because of PSO differ significantly for those of bullied for other reasons (P < .05).
For 8th grade, the sample sizes were: male, n = 3431, female, n = 3815; depressed mood: male, n = 3803, female, n = 4113; considered suicide: male, n = 3800, female, n = 4111.
For 10th grade, the sample sizes were: male, n = 4537, female, n = 5141; depressed mood: male, n = 4852, female, n = 5379; considered suicide: male, n = 4851, female, n = 5375.
For 12th grade, the sample sizes were: male, n = 3919, female, n = 4106; depressed mood: male, n = 4125, female, n = 4270; considered suicide: male, n = 4123, female, n = 4263.
