# Smoking cessation attempts and successes among Nunavimmiut

## TL;DR

This study explores why many Nunavimmiut try to quit smoking but face challenges, identifying factors like age, location, and social support that influence their attempts and successes.

## Contribution

The study provides insights into smoking cessation patterns and determinants specific to the Nunavik region, highlighting the need for culturally tailored public health interventions.

## Key findings

- 39% of smokers attempted to quit in the past year, but only 6% were successful.
- Older individuals and heavy smokers were less likely to attempt quitting, while those in the Ungava coast and occasional smokers were more likely to try.
- Most smokers did not use cessation aids, and regional and cultural factors influenced the types of aids used.

## Abstract

The smoking rate in Canada has declined in past decades, yet smoking rates remain high in Nunavik (northern Québec), where an estimated 80% of adult respondents smoke. We investigated sociodemographic factors, smoking behaviours, harm perception, and social support as determinants of smoking cessation attempts and successes among Nunavimmiut.

Past year smoking frequency, quantity smoked, and cessation attempts and aids were documented in a sample of 1326 Nunavimmiut aged 16 and over in the Qanuilirpitaa? 2017 survey. Sociodemographic indicators, social support, cessation aids, and smoking harm perception were investigated as potential determinants. All factors were modeled by logistic regressions and adjusted for age and sex.

Thirty-nine percent of smokers tried to quit smoking in the preceding year, and 6% of those were successful. Older Nunavimmiut (aOR = 0.84 [0.78, 0.90]) and those smoking 20 + cigarettes/day (aOR = 0.94 [0.90, 0.98]) were less likely to attempt to quit. Ungava coast residents (aOR = 1.87 [1.36, 2.57]), separated/widowed/divorced individuals (aOR = 2.43 [1.09, 5.38]), and occasional smokers (aOR = 2.77 [1.61, 4.76]) compared to those living on the Hudson coast, single individuals, and daily smokers, respectively, were more likely to report cessation attempts. Most used no particular cessation aid (58%), 28% relied on family/self-help/support programs, and 26% used medication. Women were more likely to rely on spirituality/traditional methods (aOR = 1.92 [1.00, 3.71]) and less likely to rely on electronic cigarettes (aOR = 0.33 [0.13, 0.84]), as were older participants (aOR = 0.67 [0.49, 0.94]). Those with more years of schooling were more likely to rely on electronic cigarettes (aOR = 1.47 [1.06, 2.02]). These estimates are prone to biases due to the relatively low participation rate in the survey (37%).

Despite many attempts reported by participants, regional partners of this study underlined that successful smoking cessation remains a challenge for many Nunavimmiut. Key differences were identified in approaches and determinants of smoking cessation attempts, but most smokers did not use cessation aids. These results are in line with the experience of the Inuit partners of this study and can inform targeted public health interventions to support the many Nunavimmiut trying to quit smoking, notably increasing accessibility and acceptability of cessation aids. Inuit partners of this study highlighted the importance for interventions and communication efforts to reflect Nunavik’s context.
