Abstract

 

Objectives: osteoporosis is one of the main causes of disability and mortality in older adults. Bone mass and density decreased slowly over time, and the most symptoms cannot be seen until the first fracture occurs. The purpose of this study is to investigate The Effectiveness of educational program based Trans-Theoretical Model (TTM) in prevention of osteoporosis in women. Study Design: quasi experimental study. Methods: This study was conducted on 160 patients (80 experimental and 80 control), who were registered under the health centers in Fasa City, Fars Province, Iran were selected in 2016. A questionnaire consisting of demographic information, TTM constructs was used to measure nutrition and walking performance for prevention of osteoporosis before, 6 months after intervention and 12 months later. Bone mineral density (BMD) was recorded at the lumbar spine and femur before and 12 months later intervention. Data were analyzed using SPSS22 via chi-square test, independent t-test, Mann-Whitney -Wilcoxon test and Repeated Measurement ANOVA at significance level of 0.05. Results: According to the results, the experimental group showed a significant increase in the pros, cons, self-efficacy, processes of change, nutrition and walking performance compared to the control group six months and one year after the intervention. 12 months after the intervention, the value of lumbar spine and Hip BMD T-Score in the experimental group increased, while in the control group it reduced. Conclusion: Applying the TTM Model is very effective for developing an educational program for prevention of osteoporosis in women. Hence, this model can act as a framework for designing and implementing educational interventions for the osteoporosis prevention.
