A home-based, transtheoretical change model designed strength training intervention to increase exercise to prevent osteoporosis in Iranian women aged 40-65 years: a randomized controlled trial

Abstract

Physical activity (PA) helps to prevent osteoporosis, but older women are often sedentary. This study used a pre-post randomized controlled design to evaluate a 12-week exercise education intervention program based on the stages of change (SoC) and processes of change from the transtheoretical change model (TTM) to improve adherence with strength and balance training recommendations at levels sufficient to prevent osteoporosis in Iranian women aged 40-65 years. The home-based exercise prescription consisted of strength and balance training that was progressive, individually tailored and included a walking program. Individuals in the training group (n=61) had a positive, significant progression in psychological SoC (P<0.001), whereas no progression in stages occurred in the control group (n=55). After the intervention, the training group demonstrated significant improvements in PA, lower body muscle strength, static and dynamic balance, with no significant changes in the control group. These results support the applicability of the TTM for a PA intervention and indicate that this training program is very effective in improving balance and lower body strength in older women.

Effects of a Theory Based Intervention on Physical Activity Among Female Employees: A Quasi-Experimental Study

“…Some studies have shown that subjective norms have a minor role in predicting the behavioral intention of the adults in the TPB model (35), which is in agreement with the findings of the present study. Also, another study shows that the important role of subjective norms in behavioral intention can decrease with an increase in age.…”

The Effect of a TTM-Based Intervention on Level of Physical Activity in ICU Nurses

“…The results obtained by Ghahremani et al on the implementation of training interventions for the promotion of MET in old men (22) and those obtained by Shirazi et al (23) and Farmanbar indicating a significant increase in the level of physical activity and participants' progression in SOC of physical activity after a SOC-based intervention (24) confirm the present findings. The distribution of participants into the five stages (pre-contemplation, contemplation, preparation, action, and maintenance) also showed a significant change.…”

“…Also, intention to have a future mammogram was more significant than previous mammography in relation pros and cons scores. Additionally, the present results are in congruence with Frenn & Malin who found that participants' use of the processes of change related to a low-fat diet increased across stages [13]. Also, participants' use of the processes related to exercise increased significantly across stages.…”
