Abstract
The aim of this study is investigating the efficiency of educational intervention based on PRECEDE model on promotion of osteoporosis prevention behaviors in women. This quasi-experimental study was conducted on 200 women registered in two health centers of Fasa city, Fars province, Iran in 2017 to 2018. A questionnaire including items evaluating demographic information and PRECEDE model constructs was used for measuring nutrition and walking performance of studied women in osteoporosis prevention before and 12 months after intervention. Bone mineral density (BMD) was recorded at the lumbar spine and femur before and 12 months after intervention. One year after intervention, the intervention group showed a significant increase in knowledge, attitude, self-efficacy, reinforcing factors, enabling factors, nutrition, and walking performance compared to the control group. Also, the value of lumbar spine and hip BMD T-Score of the intervention group was increased, while this value was reduced in the control group. Our findings showed that educational interventions based on PRECEDE model can positively affect prevention behaviors from osteoporosis by improving subjects' knowledge, attitude, enabling factors (resources such as health care access and services that can provide motivation for prevention behaviors from osteoporosis in women), self-efficacy, and reinforcing factors.
