This should come as no great surprise, given that there has been knowledge of this changing technology for some time. The rapid evolution of new information and communication technology (ICT) over the past two decades has resulted in changes in lifestyles and a distinct social reality (García del Castillo, López-Sánchez, Tur-Viñes, García del Castillo-López, & Ramos, ( 2014a). More efforts in body image are needed in order to use these tools for prevention and promotion of health from early age. Data allow us to understand how online social network behavior and interaction is related to their burden and interventions developed in sexual health and addiction show positive results. Literature review points out the role of online social networks, particularly in the field of sexual health, body image, especially eating habits and overweight, as well as smoking and alcohol dependence. The aim of this work is then to explore the theoretical relevance of ICT, particularly on online social networks, on disease prevention and health promotion of communicable diseases. As traditional social networks, they can act as vehicles to improve the health of adolescents and youth, as well as play a key role in an educational context. Online social networks have become an important source of information for users as well as a tool for social relations.


The emergence of information and communication technologies (ICT) has generated a number of research questions, related to their use and potential risk, but also potentials for prevention or health promotion.
