A) In most societies, it is often difficult for teenagers to obtain correct information about some issues related to them, such as sex, condom use, reproductive health, AIDS and sexually transmitted diseases. This is caused by many reasons: social and cultural level, economic deprivation, taboo, lack of information and so on. Many times, even if teenagers can get information, the way to give information to teenagers may be subjective, or sometimes it is not suitable for teenagers' values and lifestyles.

An effective way to deal with these problems is peer education, because it is a dialogue on the basis of equality. Usually in the form of informal parties. For example, it may be a discussion on a topic under the guidance of the host. In this process, information and knowledge are transmitted. The effectiveness of peer education lies in its social participation, which enables young people to participate in discussions and activities-doing it in person is more conducive to learning than simply obtaining information. Therefore, peer education is a very suitable way to spread AIDS information. It allows young people to participate in various activities, which can be games, competitions or role-playing. All these can help people see new things instead of being told what to think or do.
