[Interventions involving parents in order to impact adolescent sexual behavior]

To examine the effects of educational interventions that incorporate parent participation to modify adolescent sexual behavior.We conducted a systematic search of 5 electronic databases for articles published between 2002 and 2009 that evaluated educational interventions involving parents.Nineteen articles evaluated 15 interventions that met all the criteria for inclusion. They found a significant increase in adolescents' intentions to postpone sexual intercourse and use contraceptives, a reduction in self-reported sexual relations and an increase in condom use. Positive results were also found for individual protective factors such as knowledge and attitude, and family factors such as parent-child communication, perception of rules, monitoring/supervision by parents and family support.Educational interventions that include parents support healthy sexual behavior among adolescents. Parental participation can be included in any intervention aimed at adolescents.
