Purpose

This study aimed to determine the impact of a healthy lifestyle empowerment program on health-related quality of life and adherence to health-promoting behaviors in coronary artery bypass graft patients.

Methods

This non-randomized controlled trial was conducted in 2019 on 97 coronary artery bypass graft patients in Iran. Participants were selected by culturally pragmatic and non-randomized method and assigned to healthy lifestyle empowerment program group (HLEPG) (n = 49) and conventional education group (CEG) (n = 48). Data were collected by the 12-item short-form health survey (SF-12) and health-promoting lifestyle profile II (HPLP2), which were administered at baseline and three-month follow-up. The healthy lifestyle empowerment program and conventional education as two interventions were performed for HLEPG and CEG, respectively. Data analysis was performed using the paired t-test, independent t-test, analysis of covariance and linear mixed method at the 0.05 significance level.

Results

In the follow-up, both groups showed a significant increase in the mean score of health-related quality of life (p ≤ 0.001) but this increase was visibly greater in the HLEPG (from 23.47 ± 7.48 to 35.60 ± 5.95) than in the CEG (from 22.93 ± 5.93 to 27.6 ± 4.90). The healthy lifestyle empowerment program also significantly increased the mean score of adherence to health-promoting behaviors in the HLEPG (p ≤ 0.001), whereas no such change was observed in the CEG. The results of the linear mixed model showed that the follow-up scores health-related quality of life and adherence to health-promoting behaviors of the HLEPG were 27.26 and 7.56 units significantly greater than the CEG after HLEP, respectively (p < 0.001).

Conclusion

Considering the results of this study, health care providers are recommended to devise and implement healthy lifestyle empowerment programs to improve the health-related quality of life of coronary artery bypass surgery patients.

改善冠状动脉搭桥术患者的健康相关生活质量和坚持健康促进行为：一项非随机对照试验研究

目的

这项研究旨在确定健康的生活方式授权计划对冠状动脉搭桥移植患者中与健康相关的生活质量和坚持健康促进行为的影响。

方法

这项非随机对照试验于2019年在伊朗对97位冠状动脉搭桥术患者进行了研究。通过文化上务实且非随机的方法选择参与者，并将其分配给健康生活方式赋权计划组（HLEPG）（n  = 49）和常规教育组（CEG）（n  = 48）。通过12个项目的简短健康调查（SF-12）和促进健康的生活方式简介II（HPLP2）收集数据，这些数据在基线和三个月的随访中进行管理。对HLEPG和CEG分别进行了健康生活方式赋权计划和常规教育作为两项干预措施。使用配对的t进行数据分析检验，独立t检验，协方差分析和线性混合方法（显着性水平为0.05）。

结果

在随访中，这两个群体表现出的生活（健康相关质量的平均得分显著增加p  ≤0.001），但这一增长在HLEPG比明显较大（从23.47±7.48至35.60±5.95） CEG（从22.93±5.93到27.6±4.90）。健康的生活方式授权方案也显著上升遵守的平均分，以促进健康的行为在HLEPG（p  ≤0.001），而在CEG没有观察到这种变化。线性混合模型的结果表明，HLEPG的随访评分与健康相关的生活质量和坚持健康促进行为的评分分别比HLEP后的CEG高27.26和7.56个单位（p  <0.001）。

结论

考虑到这项研究的结果，建议医疗保健提供者设计并实施健康的生活方式赋能计划，以改善冠状动脉搭桥手术患者的健康相关生活质量。
