Unfortunately, due to the need to limit the number of items, questions regarding condom use during oral sex were not included. Family structure was collapsed into 4 categories: Prevalence estimates of condom use for vaginal and anal sex were computed only for students who were currently sexually active ie, reported having sex in the past 3 months. This information may help to prioritize needs for middle school sexual health education to prevent or mitigate the consequences of early sexual initiation among potentially high-risk youth populations. Multivariate logistic regression analysis was used to examine associations between demographic variables and lifetime intercourse experience. Among students who had initiated more than 1 type of intercourse, frequencies were calculated to examine the relative age of initiation for each type of sex ie, whether a specific type of sex was initiated at a younger age, the same age, or an older age relative to the other type of intercourse. Previous studies among older adolescents report contrasting findings regarding the sequence of sexual initiation. It also allowed for an automatic skipping procedure to limit exposure of nonsexually experienced students to sexually explicit items. These findings have implications for early adolescent school-based sexual health education. Of those students, between 3. Reasons for nonparticipation included being absent on survey dates or refusal to participate. Age was dichotomized as 12 years versus years since the majority of students were 12 years old. Analytic Procedures Prior to analysis, 5 students were removed from the data set due to missing data regarding lifetime intercourse, and 23 students were removed due to small counts for a specific age ages 11, 15, and 16 leaving a total sample of for analysis. However, public sensitivity regarding sexual behavior surveys among early adolescents, particularly in public school settings, has impeded this research. Data were collected between November and January ; student consent was obtained at the time of the survey.
