Background: Afghanistan ranks among the most disadvantaged globally for many key reproductive, maternal, newborn and child health (RMNCH) indicators, despite important gains in the past decade. Youth (15 to 24 years) are a key audience for RMNCH information as they enter adulthood, marry and begin families; however, reaching Afghan youth with health information is challenging. Internally displaced persons (IDPs), including youth, experience additional challenges to obtaining health-related information and services. This study measured current and preferred RMNCH information channels to explore the feasibility of using mobile phone technology to provide RMNCH information to IDP youth in Afghanistan. Methods: We conducted a sub-group analysis of survey data from a mixed-methods, cross-sectional, formative assessment to understand current access to RMNCH information. The target population for this analysis includes 15-25-year-old male and female IDP youth from three Afghan Provinces. Survey data were collected using a structured questionnaire administered through face-to-face interviews. Data were analyzed descriptively. Results: A total of 450 IDP youth were surveyed in the three provinces (225 male and 225 female). Access to RMNCH information outside of health facilities was limited. Mobile phone ownership was nearly universal among male participants, yet considerably lower among females; nearly all participants without personal phones reported access to phones when needed. Although few participants spontaneously mentioned mobile phones as a preferred source of RMNCH information, most male and female respondents reported they would be very or somewhat likely to use a free, mobile-phone-based system to access such information if offered. Conclusions: Given widespread access and considerable interest voiced by participants, mobile phones may be a viable way to reach IDP youth with important RMNCH health information in this fragile setting. Interventions should be designed and pilot-tested to identify the most appropriate platforms and information content and to further document feasibility and acceptability.
