Meet us on the phone: Mobile phone programs for adolescent sexual and reproductive health in low-to-middle income countries

Evidence from mHealth programs is generating increasing data about the potential for knowledge and behavior change from mHealth interventions. The diversity and scale of mHealth interventions identified in this review reflect how health care professionals are increasingly leveraging mobile phones to reach adolescents with essential sexual and reproductive health information and services. Given that the field of mHealth is still emerging, more evidence is needed on the cost, impact and sustainability of such interventions in low-to-middle-income country contexts.
