“…In Canada, 37 000 deaths each year 1 and 21% of all deaths over the past decade are attributable to smoking. 2 Despite widespread prevention programmes, explicit health warnings, anti-smoking legislation and declines in the social acceptability of smoking, far too many youth try smoking and continue to smoke into adulthood. Until recently, prevailing models of smoking behaviour postulated that nicotine dependence (ND) developed only after several years of regular smoking.…”

The Nicotine Dependence in Teens (NDIT) study is a prospective cohort investigation of 1294 students recruited in 1999-2000 from all grade 7 classes in a convenience sample of 10 high schools in Montreal, Canada. Its primary objectives were to study the natural course and determinants of cigarette smoking and nicotine dependence in novice smokers. The main source of data was self-report questionnaires administered in class at school every 3 months from grade 7 to grade 11 (1999-2005), for a total of 20 survey cycles during high school education. Questionnaires were also completed after graduation from high school in 2007-08 and 2011-12 (survey cycles 21 and 22, respectively) when participants were aged 20 and 24 years on average, respectively. In addition to its primary objectives, NDIT has embedded studies on obesity, blood pressure, physical activity, team sports, sedentary behaviour, diet, genetics, alcohol use, use of illicit drugs, second-hand smoke, gambling, sleep and mental health. Results to date are described in 58 publications, 20 manuscripts in preparation, 13 MSc and PhD theses and 111 conference presentations. Access to NDIT data is open to university-appointed or affiliated investigators and to masters, doctoral and postdoctoral students, through their primary supervisor (www.nditstudy.ca).

“…While older age was not an 13 exclusion criterion and 21.5% of patients were less than 60 years old in the current study, those less than 65 years were excluded from the study in the United States. Moreover, a lower frequency of obesity and cigarette smoking in Canadians as compared with Americans may be another factor contributing to the observed differences in cardiovascular diseases (26,27).…”

Background: Baseline cardiovascular disease can impact the patterns of treatment and hence the outcomes of patients with lung cancer. This study aimed to characterize treatment trends and survival outcomes of patients with pre-existing cardiovascular disease prior to their diagnosis of lung cancer.Methods: We conducted a retrospective, population-based cohort study of patients with lung cancer diagnosed from 2004 to 2015in a large Canadian province. Multivariable logistic regression and Cox regression models were constructed to determine the associations between cardiovascular disease and treatment patterns, and its impact on overall and cancer-specific survival, respectively.Results: A total of 20,689 patients with lung cancer were eligible for the current analysis. Men comprised 55%, and the median age at diagnosis was 70 years. One-third had at least one cardiovascular disease, with the most common being congestive heart failure in 15% of patients. Pre-existing cardiovascular disease was associated with a lower likelihood of receiving chemotherapy (odds ratio [OR],0.53;95% confidence interval [CI],0.48-0.58;P < .0001), radiotherapy (OR,0.76;95% CI,0.7-0.82;P < .0001), and surgery (OR, 056; 95% CI,0.44-0.7;P < .0001). Adjusting for measured confounders, the presence of pre-existing cardiovascular disease predicted for inferior OS (hazard ratio [HR], 1.1; 95% CI, 1.1-1.2; P < .0001) and CSS (HR,1.1; 95% CI, 1.1-1.1; P < .0001). Conclusions: Patients with lung cancer and pre-existing cardiovascular disease are less likely to receive any modality of cancer treatment and have poor OS and CSS. As effective therapies such as immuno-oncology drugs are introduced, early cardio-oncology consultation may optimize management and outcomes of lung cancer.

“…Cigarette smoking remains a serious public health concern and is the leading cause of premature chronic disease and mortality in Canada, accounting for 21% of deaths over the last decade (Jones et al, 2010). In 2014, 14.3% of British Columbians ≥12 years reported smoking, with 17.4% of males and 11.3% of females reporting current smoking (Statistics Canada, 2016).…”

Background Cigarette smoking is common among gay, bisexual, and other men who have sex with men (GBMSM) and most of the mortality gap between HIV-positive and HIV-negative individuals is attributable to smoking. Methods We recruited sexually active HIV-positive and HIV-negative GBMSM age ≥16 years using respondent-driven sampling. Study visits occurred every six months for up to four years and included a computer-assisted self-interview and clinical assessment. We conducted bivariate analyses to compare factors associated with “never”, “former”, “daily”, or “non-daily” smoking at baseline and longitudinal mixed effects models to examine factors associated with cessation and (re)initiation. Results 774 participants completed a baseline visit and 525 enrolled in the cohort and completed at least one follow-up visit. At baseline, the median age was 34 years and 31.5% were daily smokers. In follow-up (median=2.5 years), 116 daily or non-daily smokers (41%) quit at least once and of these, 101 (87%) remained former smokers at their last visit. Smoking cessation was positively associated with incomes ≥$60,000 and self-reported excellent health. Alcohol use, ecstasy use, and having a partner who smokes were associated with decreased odds of cessation. Substance use (cannabis, GHB, and crystal methamphetamine) and having a partner who smokes were positively associated with increasing to/resuming daily smoking. HIV-positive GBMSM were more likely to smoke but not more likely to quit. Conclusions Targeted, culturally relevant smoking cessation resources are needed, especially for HIV-positive GBMSM. Engaging couples in cessation interventions may be useful.
