ABSTRACT

Background: The current study aims to evaluate the rates and associations of cannabis use among Canadian adults with cancer (2007-2016).

Methods: Canadian Community Health Survey (CCHS) (2007-2016) was accessed and adult participants who answered yes to the question “Do you have cancer?” and who have complete information about cannabis use were included. Multivariable logistic regression was used to identify factors associated with cannabis use.

Results: A total of 4667 participants who currently have cancer were included in the current analysis. The rate of cannabis use increased throughout the study (34.4% in 2015-2016 versus 27.7% in 2007-2008). The following factors were associated with cannabis use: younger age (OR: 3.64; 95% CI: 2.27-5.86; P<0.01); male sex (OR: 2.11; 95% CI: 1.80-2.48; P<0.01); white race (OR: 2.02; 95% CI: 1.46-2.78; P<0.01); single status (OR for married versus single: 0.38; 95% CI: 0.29-0.50; P<0.01) and higher income (OR for income < 20,000 versus income ≥ 80,000: 00.74; 95% CI: 0.56-0.99; P=0.04).

Conclusions: Within this study cohort of Canadian adults with current cancer diagnosis, cannabis use is not uncommon. A history of cannabis use is associated with younger age, male sex, white race, non-married status, and higher income.

摘要

背景：目前的研究旨在评估加拿大癌症成人（2007-2016 年）使用大麻的比率和关联。

方法：访问了加拿大社区健康调查 (CCHS)（2007-2016 年），成年参与者对“你有癌症吗？”这个问题的回答是肯定的。以及拥有关于大麻使用的完整信息的人也被包括在内。多变量逻辑回归用于确定与大麻使用相关的因素。

结果：目前的分析共包括 4667 名目前患有癌症的参与者。在整个研究过程中，大麻使用率有所增加（2015-2016 年为 34.4%，而 2007-2008 年为 27.7%）。以下因素与使用大麻有关：年龄较小（OR：3.64；95% CI：2.27-5.86；P<0.01）；男性（OR：2.11；95% CI：1.80-2.48；P<0.01）；白种人（OR：2.02；95% CI：1.46-2.78；P<0.01）；单身状态（已婚与单身的 OR：0.38；95% CI：0.29-0.50；P<0.01）和更高收入（收入 < 20,000 与收入 ≥ 80,000 的 OR：00.74；95% CI：0.56-0.99；P=0.04 ）。

结论：在这项针对目前诊断为癌症的加拿大成年人的研究队列中，大麻的使用并不少见。使用大麻的历史与年龄较小、男性、白人、未婚状态和较高的收入有关。
