自我引导的运动能改善部分控制成人哮喘患者的健康感知
2010/12/17
摘要
背景：监督下运动能够明显改善哮喘部分控制的成人哮喘患者的哮喘控制水平和生活质量。然而，非监督下运动对哮喘的作用尚不清楚。
方法：本试验旨在研究自我引导的运动对哮喘相关主观和客观健康指标的影响。24名参与者分为运动组和对照组，试验为期12周。运动组患者由有资质的运动专家为其制定运动计划。运动计划每3周通过电子邮件的方式更新一次，以确保患者及时更新。对照患者在研究期间维持目前的生活方式和生活习惯。在基线状态和12周的研究结束后，对两组受试者的有氧适能、肺功能以及主观和客观哮喘检测指标进行评价。采用协方差分析检测基线状态与试验结束时的差异。运用定性分析评价患者对开放式问题的反应。
结果：患者对运动计划的依从性较差。在12周研究结束后，与对照组相比，运动组患者所感知的哮喘控制、自我主诉的频率和哮喘严重程度均有显著改善。哮喘相关客观指标，如哮喘控制、生活质量、肺功能以及最大和较大有氧适力，与对照组相比，并未出现显著改善。对开放式问题的反应显示在下列3个区域存在改善：哮喘管理、认知力和健康感受。
结论：哮喘部分控制的成人患者，经过为期12周的自我指导式运动后，能改善感知的哮喘控制以及哮喘相关的健康主观指标。然而，有必要对运动进行监督，这能显著改善客观哮喘控制、生活质量和有氧适力。在此类患者中，今后研究需针对提高患者对自我指导运动计划依从性的措施。

Abstract
Background. Supervised exercise leads to significant improvements in asthma control and quality-of-life in adults with partly controlled asthma; however, the role of unsupervised exercise is unknown. Methods. The purpose of this study was to determine the impact of self-directed exercise on subjective and objective indices of asthma-related health. Participants (n=24) were assigned to an exercise group or a control group for a 12-week period. Those in the exercise group were provided with exercise programs by a qualified exercise professional. These programs were updated through electronic mail every 3 weeks to ensure progression. Controls maintained their current lifestyle habits for the intervention period. Assessments of aerobic fitness, lung function, and subjective and objective asthma measures were conducted at baseline and after completion of the 12-week intervention period for both groups. Analysis of covariance was used to detect differences between groups from baseline to week 12. Qualitative analyses were used to assess responses to open-ended questions. Results. Adherence to the program was poor. Perceived asthma control and self-reported frequency and severity of asthma improved significantly in the exercise group at week 12 compared with that in the control group. Objective measures of asthma such as asthma control, quality-of-life, and lung function, as well as peak and submaximal aerobic fitness did not change relative to controls. Responses to open-ended questions revealed improvements in three areas: asthma management, perceived fitness, and well-being. Conclusion. Adults with partly controlled asthma are able to improve perceived control and subjective measures of asthma-related health with 12 weeks of self-directed exercise; however, supervision may be required to make significant improvements to measured asthma control, quality of life, and aerobic fitness. Future research should focus on the means to improve adherence of self-directed exercise programs in this population.
