A study by researchers at the Bradley Hasbro Children's Research Center and Brown Medical School has showed that teens are more likely to use condoms with partners they perceive as "casual" than with a "main" or serious partner. However, the study also found that the number of unprotected sex acts between both main and casual partners was substantial and equivalent.
These findings suggest that not only are teens at a high risk for sexually transmitted diseases, but that they underestimate the risk of unprotected sex with a main partner.
According to the study's lead author, Celia Lescano, PhD, targeting how adolescents view partner types and the risks associated with them will be vital to the success of HIV intervention programs: "This study demonstrates the importance of understanding an adolescent's perception of partner types in order to design effective interventions."
