The Application of PRECEDE Model on Preventing Osteoporosis in Women

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.

The application of the theory of planned behavior to nutritional behaviors related to cardiovascular disease among the women

“…In a study by Welsh et al, which examined the effect of educational intervention based on the TPB on low-salt diet among the patients with heart failure in 2012, the results showed that after 6 months, dietary sodium in the experimental group significantly decreased compared to the control group [ 81 ]. The results of other studies were consistent with the results of this study [ 82 – 84 ].…”

Effect of educational intervention based on PRECEDE model on lifestyle modification, self-management behaviors, and hypertension in diabetic patients

“…a current investigation by Bazrpour et al [23], there was a significant increase in knowledge immediately and one month after the intervention. The results of our study were consistent with the result of studies by Wang et al [14], Khani Jeyhooni et al [24], Koc et al [25], and Kaewchi et al [26]. Using group discussion, brainstorming, and participating individuals and peers pave the way to share information and experiences.…”

“…Our results were consistent with those of other studies because patients' self-care benefits greatly from the support of medical experts, family, and friends. [16,30,31]; with the difference in the mentioned studies the sample size and the number of training sessions were less, and also in the study of Solhi et al, they used the self-management theory in addition to the Persed model for educational intervention. The enabling elements significantly changed after the educational intervention due to improvements in knowledge, attitude, self-efficacy, and reinforcing factors.…”
