The postoperative severity of symptoms among women with breast cancer affects their quality of life (QoL). Although it is recommended that performing shoulder-arm exercise 30 min/day can alleviate symptoms and improve the QoL, there is little research on the mediating effects of performing shoulder-arm exercise 30 min/day on the postoperative severity of symptoms and QoL among patients with breast cancer.
A cross-sectional study was conducted 2 ~ 4 months after surgery on women diagnosed with breast cancer but with no distant metastasis and who had undergone breast cancer surgery for the first time. A structured questionnaire was employed which included a severity of symptoms scale, performing shoulder-arm exercise for 30 min/day, a QoL scale, demographic characteristics, and medical status.
In total, 117 women with breast cancer completed the survey. The severity of symptoms and performing shoulder-arm exercise 30 min/day separately affected the QoL (B = -0.447, standard error (SE) = 0.050, p < 0.001; B = 15.666, SE = 4.542, p = 0.001, respectively). In model 3, performing shoulder-arm exercise for 30 min/day played a partial mediating role in the relationship of the severity of symptoms and QoL (R = 0.51, F = 5.41, p < 0.001).
During 2 ~ 4 months after surgery, regular shoulder-arm exercise for 30 min/day could decrease the effect of the severity of symptoms on the QoL among women with breast cancer. Clinical healthcare providers may inform and educate patients as to the benefits of regular shoulder-arm exercise for 30 min/day.
乳腺癌女性术后症状严重程度影响其生活质量（QoL）。尽管建议每天进行 30 分钟的肩臂运动可以缓解症状并提高 QoL，但对于每天进行 30 分钟的肩臂运动对乳腺癌患者术后症状严重程度和 QoL 的中介作用研究较少。
对首次接受乳腺癌手术且无远处转移的女性患者进行术后 2-4 个月的横断面研究。采用结构问卷，包括症状严重程度量表、每天进行 30 分钟的肩臂运动、生活质量量表、人口统计学特征和医疗状况。
共有 117 名乳腺癌女性完成了调查。症状严重程度和每天进行 30 分钟的肩臂运动分别影响 QoL（B=-0.447，标准误（SE）=0.050，p<0.001；B=15.666，SE=4.542，p=0.001）。在模型 3 中，每天进行 30 分钟的肩臂运动在症状严重程度和 QoL 之间的关系中发挥了部分中介作用（R=0.51，F=5.41，p<0.001）。
在术后 2-4 个月期间，每天进行 30 分钟的规律肩臂运动可以降低乳腺癌女性症状严重程度对 QoL 的影响。临床医护人员可以向患者告知并教育他们每天进行 30 分钟的肩臂运动的益处。
