背景。在一些癌症幸存者群体中，缺乏运动和肥胖与较差的疾病预后有关。然而，很少有研究对癌症幸存者的这些危险因素进行基于人群的估计，并将其与没有癌症病史的个体进行比较。在此报告对加拿大人口的估计。数据来自2005年加拿大社区健康调查，该调查包括对114,355名成年人的计算机辅助访谈，估计代表了23,285,548名加拿大人。参与者自我报告他们的癌症病史、身高和体重，以计算身体质量指数和参加各种休闲活动。不到22%的加拿大癌症幸存者进行体育锻炼，超过18%的人肥胖。癌症幸存者与无癌症病史者之间几乎没有差异，除了：1)前列腺癌幸存者更有可能运动（校正比值比[OR] = 1.27； 95%可信区间[CI] = 1.01-1.59），更不可能肥胖（校正比值比[OR] = 0.71; 95% CI = 0.56-0.90）；2)皮肤癌幸存者（非黑色素瘤和黑色素瘤）更有可能运动（调整后OR = 1.33; 95% CI = 1.12-1.59）；3)与无癌症史的肥胖女性相比，肥胖乳腺癌幸存者更不可能运动（调整后OR = 0.51; 95% CI = 0.27-0.94）。加拿大癌症幸存者的身体活动水平低，肥胖患病率高，尽管与一般人群相当，但可能使他们患较差疾病结果的风险更高。以人群为基础的干预措施，以增加身体活动和促进加拿大癌症幸存者的健康体重是必要的。
BACKGROUND. Physical inactivity and obesity are associated with poorer disease outcomes in several cancer survivor groups. Few studies, however, have provided population-based estimates of these risk factors in cancer survivors and compared them with individuals without a history of cancer. Here such estimates for the Canadian population are reported.METHODS. Data were obtained from the 2005 Canadian Community Health Survey consisting of computer-assisted interviews of 114,355 adults representing an estimated 23,285,548 Canadians. Participants self-reported their cancer history, height, and body weight to calculate body mass index and participation in various leisure-time activities.RESULTS. Fewer than 22% of Canadian cancer survivors were physically active and over 18% were obese. Few differences were observed between cancer survivors and those without a history of cancer except that: 1) prostate cancer survivors were more likely to be active (adjusted odds ratio [OR] = 1.27; 95% confidence interval [CI] = 1.01-1.59) and less likely to be obese (adjusted OR = 0.71; 95% CI = 0.56-0.90); 2) skin cancer survivors (nonmelanoma and melanoma) were more likely to be active (adjusted OR = 1.33; 95% CI = 1.12-1.59); and 3) obese breast cancer survivors were less likely to be active compared with obese women without a history of cancer (adjusted OR = 0.51; 95% CI = 0.27-0.94).CONCLUSIONS. Canadian cancer survivors have low levels of physical activity and a high prevalence of obesity that, although comparable to the general population, may place them at higher risk for poorer disease outcomes. Population-based interventions to increase physical activity and promote a healthy body weight in Canadian cancer survivors are warranted.
