Due to the nature of their activities, housewives are often at higher risk of weight gain. Considering the importance of interventions and the role of housewives in the family, the present study was designed and conducted to examine the impact of training based on the Transtheoretical Model on increasing physical activity in overweight and obese housewives.
This quasi-experimental study was conducted on 120 overweight and obese housewives attending comprehensive health centers in Yazd, Iran. The sampling method was multi stage, and participants were randomly assigned to two groups: intervention (60 participants) and control (60 participants). The educational intervention consisted of six 90-minute sessions held over one and a half months (one session per week) in person. The educational content provided to the intervention group was based on the Transtheoretical Model. Data collection tools included standardized physical activity and behavior change questionnaires based on the Transtheoretical Model, Data were analyzed using SPSS version 27 with paired t-tests, independent t-tests, and chi-square tests.
Independent t-test results showed after the intervention, the differences between two group were statistically significant (P = 0.001). Additionally, independent t-test results showed no significant difference in physical activity levels between the intervention and control groups before the educational intervention (P = 0.312), whereas the difference became statistically significant after the intervention (P = 0.001).
The findings of this intervention demonstrated that interventions based on the Transtheoretical Model effectively improve behavior, identify barriers and benefits of physical activity, and enhance self-efficacy in overweight and obese housewives. This study revealed that the Transtheoretical Model, through identifying perceived barriers and benefits (via the training provided) and, most importantly, improving self-efficacy and behavior, led to an increase in physical activity among housewives.
由于家庭主妇的活动性质，她们往往有更高的体重增加风险。考虑到干预措施的重要性以及家庭主妇在家庭中的作用，本研究旨在设计并实施，以检验基于跨理论模型的培训对超重和肥胖家庭主妇增加身体活动的影响。
本准实验研究对120名在伊朗亚兹德综合健康中心就诊的超重和肥胖家庭主妇进行。抽样方法为多阶段抽样，参与者被随机分为两组：干预组（60名参与者）和对照组（60名参与者）。教育干预包括在一个半月内亲自举办六次90分钟的课程（每周一次）。向干预组提供的教育内容基于跨理论模型。数据收集工具包括基于跨理论模型的标准化身体活动和行为改变问卷。数据使用SPSS 27版进行分析，采用配对t检验、独立t检验和卡方检验。
独立t检验结果显示，干预后两组之间的差异具有统计学意义（P = 0.001）。此外，独立t检验结果显示，在教育干预前，干预组和对照组的身体活动水平无显著差异（P = 0.312），而干预后差异具有统计学意义（P = 0.001）。
本次干预的结果表明，基于跨理论模型的干预有效地改善了行为，识别了身体活动的障碍和益处，并提高了超重和肥胖家庭主妇的自我效能感。本研究表明，跨理论模型通过识别感知到的障碍和益处（通过提供的培训），最重要的是，提高自我效能感和行为，导致家庭主妇的身体活动增加。
