A Survey on Physical Activity Determinants as Osteoporosis Preventive Behavior Among Pre-university Female Students of Rafsanjan in 2017: A Descriptive Study

Background and Objectives: Increasing physical activity, as a health issue, especially among girls, is one of the recommendations of the World Health Organization for the osteoporosis prevention. The present study was designed and implemented with the aim of determining the causes of physical activity among students regarding osteoporosis based on health belief model (HBM).Materials and Methods: This descriptive study was conducted among 470 preuniversity female students of Rafsanjan city by census method in 201718. The data collection tool was a questionnaire including demographic characteristics, knowledge about osteoporosis and 24 questions based on HBM constructs, and it also assessed 11 physical activity questions. The tool validity was based on experts' opinion and reliability was determined using Cronbach's alpha coefficient. Data were analyzed using oneway ANOVA, independent ttest and Pearson's correlation test.Results: The number of participants in this study was 470 students. The knowledge related to osteoporosis among students was undesirable (score 6 out of 15). 253 (53.8%) of students had moderate physical activity. There was a significant reverse correlation between the mean score of physical activity and perceived barriers (r=0.1, p<0.001). But there was no significant relationship between physical activity and other structures and demographic characteristics (p> 0.05).Conclusion: Due to undesirable physical activity and knowledge of students, designing and implementing educational interventions are recommended. It is also necessary to identify other determinants affecting physical activity, such as enabling and reinforcing factors.Key words: Osteoporosis, Physical activity, Health belief model, Girls, Rafsanjan Funding: This research was funded by Deputy of Vice Chancellor for Research and Technology at Rafsanjan University of Medical Sciences.Conflict of interest: None declared.Ethical approval: The Ethics Committee of Vice Chancellor for Research and Technology at Rafsanjan University of Medical Sciences approved the study (IR.RUMS.REC.1395.143).How to cite this article: Aligol M, Kazemi S S, Salim Abadi Y, Nasirzadeh M, Tayyebi Z.
