Abstract

OBJECTIVES:

To (1) identify the temporal order between oral and vaginal sex onset; (2) test whether oral sex or vaginal sex is a risk or protective factor for the other; and (3) determine whether the relationship between oral and vaginal sex varies across time.

DESIGN:

Prospective, longitudinal study with 6-month assessments conducted between 2002 and 2005.

SETTING:

Self-administered surveys completed during class time.

PARTICIPANTS:

At baseline, 627 ninth grade high school students from 2 northern California schools were included in the study.

MAIN OUTCOME MEASURE:

Oral and vaginal sex onset.

RESULTS:

Among sexually active adolescents, most initiated vaginal sex after or within the same 6-month period of oral sex initiation. Adolescents who initiated oral sex at the end of ninth grade had a 50% chance of initiating vaginal sex by the end of 11th grade. In comparison, adolescents who delayed until the end of 11th grade had a 16% chance of initiating vaginal sex by the end of 11th grade.

CONCLUSIONS:

The first 2 years of high school may be a critical age period for adolescents' vulnerability to vaginal sex initiation via oral sex behaviors. Comprehensive evidenced-based interventions and provision of preventive services aimed toward reducing sexual risk should be expanded to include the role oral sex plays in adolescent sex behavior.
