Exercise has many benefits for survivors of breast cancer, yet only half of this population regularly exercise. Fear has been identified as a barrier to exercise for people with neuromusculoskeletal conditions but has been minimally explored in women with breast cancer.
The purposes of this study were: (1) to investigate factors that affected decisions about physical activity and exercise in survivors of breast cancer and (2) to determine whether fear was a factor.
This investigation was a grounded-theory qualitative study. Qualitative data were triangulated with data from 2 quantitative scales that measured participants' beliefs about exercise and their activity levels.
Thirty-four survivors of breast cancer in 8 focus groups participated in semistructured interviews that were recorded, transcribed, and coded. Concept maps created for each group were merged to develop themes. Beliefs about physical activity and exercise were assessed with the Decisional Balance Scale. The Rapid Assessment of Physical Activity was used to assess behaviors regarding physical activity and exercise before and after the breast cancer diagnosis.
Participants generally believed that exercise was beneficial (Decisional Balance Scale score: X=28.1 [of a maximum score of 44], SD=7.6, range=10-43). Participants decreased the amount of physical activity or exercise during treatment but increased the amount of exercise beyond prediagnosis levels after treatment (Rapid Assessment of Physical Activity score: median=6, range=2-7). Three prominent themes described participants' behaviors regarding physical activity or exercise: values and beliefs about exercise, facilitators and barriers that were both similar to those affecting the general population and cancer specific, and lack of or inaccurate information about safe exercise.
Survivors who were active were not afraid to exercise. However, concern about lymphedema and knowledge about safe and effective exercise programs influenced choices regarding physical activity and exercise.
运动对乳腺癌幸存者有诸多益处,但仅有一半的乳腺癌幸存者经常运动。恐惧被认为是影响患有神经肌肉骨骼疾病人群运动的一个障碍,但在乳腺癌患者中,这一问题的研究还很少。
本研究的目的是:(1)探讨影响乳腺癌幸存者进行身体活动和运动决策的因素,以及(2)确定恐惧是否是一个影响因素。
本研究是一项扎根理论的定性研究。定性数据与来自 2 个测量参与者对运动的信念和活动水平的定量量表的数据进行了三角分析。
34 名乳腺癌幸存者参加了 8 个焦点小组的半结构式访谈,访谈内容被记录、转录和编码。为每个小组创建的概念图被合并以形成主题。身体活动的信念是通过决策平衡量表来评估的。快速身体活动评估用于评估乳腺癌诊断前后与身体活动和运动相关的行为。
参与者普遍认为运动是有益的(决策平衡量表评分:X=28.1[满分 44 分],SD=7.6,范围 10-43)。参与者在治疗期间减少了身体活动量或运动量,但在治疗后增加了运动量,超过了诊断前的水平(快速身体活动评估评分:中位数=6,范围 2-7)。3 个突出的主题描述了参与者的身体活动或运动行为:对运动的价值观和信念、促进因素和障碍,这些因素与一般人群和癌症相关的因素相似,以及缺乏或对安全运动的信息不准确。
积极运动的幸存者并不害怕运动。然而,对淋巴水肿的担忧以及对安全有效的运动计划的了解,影响了他们对身体活动和运动的选择。
