Researchers from the University of Southern California and the University of Minnesota have released findings from a study exploring the affects of sexual behavior on school performance. After examining school transcripts and self-reported sexual behavior, the researchers concluded that students who were sexually active within the context of a committed relationship performed no better or worse than those who were abstinent. However, researchers did find that students who engaged in casual sex or "hook ups" had lower grades and more school-related problems than those who were abstinent. Researchers suggest that committed relationships may serve as a protective factor against stress and anxiety because the individual receives social support from their partner. Nearly half of all high school students surveyed last year reported that they had experienced sexual intercourse leading some sexuality educators to suggest that education stress the importance of relationships and the negative consequences associated with casual sex.
