This trial aims at testing the efficacy of weekly sexo-reproductive health educational text messages to improve perception of adolescent girls on sexo-reproductive health in Cameroon. This is a single-centered randomized controlled single-blinded trial. Adolescent girls aged 10 to 19 years in the Kumbo West Health District are the target population. A central computer generated randomization list was used to prevent selection bias and enable the production of the comparable groups for this trial. Allocation concealment (1:1) was determined by sequentially numbered sealed opaque envelopes. A total of 460 participants either receive the mobile phone text message or no text message. Data was collected at baseline, three month and six month intervals. A blinded program secretary sent out text messages and record delivery. The studies primary outcomes were improved knowledge and practices towards sexo-reproductive health, while its secondary outcomes were improved behaviour and attitudes towards sexo-reproductive health. Analysis was by intention-to-change behaviour. Covariates and subgroups were taken into account. This trial investigated the potential of SMS messages on sexo-reproductive health education to improve adolescent girl’s perception to attain better health outcomes. This trial contribute to the growing body of evidence on the use of mobile phone technology as a complementary strategy for strengthening health systems and achieving health-related goals oriented towards adolescent girls.


Key words: Mobile phone, sexo-reproductive health, improved perception, randomization.
