Physical activity is the most critical determinant of physical health which reduces the health risks during life. This designed study aims to evaluate the effect of educational intervention based on the theory of planned behavior on promoting physical activity among middle-aged women attending the health centers in Karaj city during 2017-2018.
This research was a quasi-experimental controlled trial, and the study incorporated 140 Middle-Aged Women Referring to Karaj Health Centers assigned randomly to a control and intervention group (70 each group). Participants enrolling in the survey were asked to complete the International Physical Activity Questionnaire and also the theory of planned behavior measures at the baseline and the end of the study. The SPSS software were used, to analyze the data. The study applied Nonparametric Wilcoxon and Mann-Whitney tests and ANCOVA to interpret the results.
The results revealed participants' age range between 30 to 50 years with the mean and standard deviation scores 40.07 (8.750) in training and 45.81 (8.513) at the control group. The intervention improved the theory of planned behavior measures and the physical activities of participants. The results showed a significant difference in the attitude score, the perceived behavioral control score, and the level of subjective norms between two training and non-training groups (P < 0.001). The followed-up physical activity score also showed an improvement in the IPAQ score of participants in the training group (p < 0.001).
The results of this specific study support the effectiveness of the theory of planned behavior for promoting the physical activity of women.
体力活动是身体健康的最关键决定因素，可以降低生活中的健康风险。本设计研究旨在评估基于计划行为理论的教育干预对促进 2017-2018 年卡伦市健康中心中年女性体力活动的影响。
这是一项准实验对照试验，研究纳入了 140 名随机分配到对照组和干预组（每组 70 名）的中年女性。被纳入调查的参与者被要求在基线和研究结束时完成国际体力活动问卷和计划行为理论测量。使用 SPSS 软件分析数据。该研究采用非参数 Wilcoxon 和 Mann-Whitney 检验和协方差分析来解释结果。
结果显示，参与者的年龄在 30 至 50 岁之间，培训组的平均年龄和标准差为 40.07（8.750），对照组为 45.81（8.513）。干预提高了计划行为理论措施和参与者的体力活动水平。结果表明，在态度得分、感知行为控制得分和主观规范水平方面，培训组和非培训组之间存在显著差异（P < 0.001）。随访体力活动评分也显示培训组参与者 IPAQ 评分有所提高（p < 0.001）。
本研究的结果支持计划行为理论对促进女性体力活动的有效性。
