Abbreviations: APR = adjusted prevalence ratio; CI = confidence interval; HIV = human immunodeficiency virus.
*Logistic regression adjusted for race/ethnicity and grade. Statistical significance is indicated when p<0.05 or 95% CI does not include 1.0. Analyses were not conducted for no condom use among females with only same-sex sexual contact or for no pregnancy prevention method use among male or female students with only same-sex sexual contact.
† Among students who ever had sexual intercourse.
§ Linear contrast t-tests reveal this sexual minority youth subgroup is significantly different from heterosexual students.
¶ Linear contrast t-tests reveal this sexual minority youth subgroup is significantly different from students who are not sure of their sexual identity.
** Linear contrast t-tests reveal this sexual minority youth subgroup is significantly different from bisexual students.
†† Linear contrast t-tests reveal this sexual minority youth subgroup is significantly different from students who had sexual contact with the opposite sex only.
¶¶ Linear contrast t-tests reveal this sexual minority youth subgroup is significantly different from students who had sexual contact with both sexes.
