Background:Adopting a healthy life style in children may protect them against osteoporosis in later life. This study was done to determine the effectiveness of gain-framed versus loss-framed using mobile phones short-messages service (SMS) intervention in promoting knowledge, attitude and preventive nutrition behaviors of osteoporosis among a sample of Iranian female students.
Materials and Methods:In this quasi-experimental study, 345 female students in Semnan, Iran were randomly selected and assigned to either intervention group 1 (receiving gain-framed text messages, n=115), intervention group 2 (receiving loss-framed text messages, n=115), and control group (no receiving text messages, n=115). Knowledge, attitude and dietary behaviors related to osteoporosis prevention were collected by a researcher-made questionnaire before and one month after the delivery of the framed information via SMS. Seventy two short messages that emphasized the benefits of adopting the behavior (n=35), and the costs of non adopting it (n=35) have been sent to the participants’ phones in intervention group 1 and 2, respectively during the 35-day intervention period.
Results: The age of participants in the three groups was 12 years. They were studying in the seventh grade. After the intervention, the mean scores of knowledge (2.32±0.60, p <0.001), attitude (1.52±0.60, p=0.03), and adopting the preventive nutrition behaviors of osteoporosis (1.30±0.58, p=0.05) variables in the intervention group 1 had a significant increase compared to the intervention group 2.
Conclusion: The results of the study showed that gain-framed text messages significantly improved adopting osteoporosis preventive nutrition behaviors than loss framed text messages.
