This project will evaluate the impact of an interactive online health promotion platform (www.jovensalud.net) and mobile app providing sexual and reproductive health (SRH) messaging on SRH knowledge and behavior (delaying age at sexual initiation, increasing condom and contraception use, improve gender equal relationships, increasing SRHR health service utilization, and decreasing intimate partner violence) in rural Nicaraguan youth (10-17 years). 25 youth and family development organizations (YFDOs) consisting of schools and youth organizations in marginalized rural areas of Nicaragua will receive awareness about the online health promotion platform and mobile app. YFDOs will promote the platform and offer the use of computer equipment and internet for teens to access the platform.
