As cancer survival rates improve, there is growing interest in the role of lifestyle in longer-term health and quality of life (QoL). This study examined the prevalence of health-related behaviours, and the associations between health behaviours and QoL, in colorectal cancer survivors.
Patients diagnosed with colorectal cancer within the last 5 years identified from five London (UK) hospitals (N = 495) completed a survey that included measures of fruit and vegetable (F&V) intake, physical activity, smoking status and alcohol consumption. The EORTC-QLQ-C30 questionnaire was used to index QoL.
The majority of respondents were overweight/obese (58%), not physically active (<5 bouts of moderate activity per week; 82%) and ate fewer than five portions of F&V a day (57%). Few were smokers (6%) or heavy drinkers (weekly alcohol units >21 for men and >14 for women; 8%). Physical activity showed the strongest association with functional QoL and was also associated with lower fatigue, pain and insomnia (P < 0.05). F&V intake was associated with higher global QoL and physical, role and cognitive function (P < 0.05). Using a total health behaviour score (calculated by assigning one point for each of the following behaviours: not smoking, consuming ≥5 portions of F&V a day, being physically active and having moderate alcohol consumption), there was a linear relationship with global QoL, physical function and fatigue (P < 0.05).
A high proportion of colorectal cancer survivors in the UK have suboptimal health behaviours, and this is associated with poorer QoL.
随着癌症存活率的提高，人们对生活方式在长期健康和生活质量（QoL）中的作用越来越感兴趣。本研究调查了结直肠癌幸存者的健康相关行为的流行情况，以及健康行为与 QoL 之间的关系。
从英国伦敦的五家医院（N=495）中确定了最近 5 年内被诊断为结直肠癌的患者，他们完成了一项调查，其中包括水果和蔬菜（F&V）摄入量、身体活动、吸烟状况和饮酒量的测量。使用 EORTC-QLQ-C30 问卷来衡量 QoL。
大多数受访者超重/肥胖（58%），每周没有进行 5 次以上的中度活动（82%），每天摄入少于 5 份 F&V（57%）。很少有人吸烟（6%）或酗酒（男性每周饮酒单位> 21，女性每周饮酒单位> 14；8%）。身体活动与功能 QoL 的关联最强，还与较低的疲劳、疼痛和失眠相关（P<0.05）。F&V 摄入量与较高的总体 QoL 和身体、角色和认知功能相关（P<0.05）。使用一个总的健康行为评分（通过为以下行为各分配 1 分来计算：不吸烟、每天摄入≥5 份 F&V、身体活跃和适度饮酒），与总体 QoL、身体功能和疲劳呈线性关系（P<0.05）。
英国结直肠癌幸存者中，很大一部分人的健康行为不理想，这与较差的 QoL 有关。
