Abstract
in English, French

Objectives: The COVID-19 pandemic has profoundly disrupted daily life in Canada. This study assesses changes in health behaviours during the early stages of the pandemic and examines socio-demographic disparities associated with these changes.

Methods: We analyze data on adults age 25 and older (N = 4383) from the public-use Canadian Perspectives Survey Series 1: Impacts of COVID-19 (CPSS-COVID). Multinomial regression models assess the association between demographic and socio-economic characteristics with increases or decreases in six health behaviours: alcohol, tobacco, and cannabis use, junk food consumption, and TV and internet screen time.

Results: While findings varied across the six behaviours, overall, there was an increase in negative health behaviours: 14% of Canadian adults reported increasing their alcohol use (95% CI = 0.12, 0.15), 25% increased their junk food consumption (95% CI = 0.23, 0.27), and over 60% increased their screen time (62%, 95% CI = 0.60, 0.65 for TV and 66%, 95% CI = 0.63, 0.68 for internet). Younger and Canada-born adults were more likely to increase negative health behaviours than older and immigrant Canadians. Adults who reported financial impact of COVID-19 were more likely to increase all negative health behaviours (e.g., for increased junk food consumption, the relative risk ratio (RRR) = 1.81, 95% CI = 1.49, 2.20 relative to group reporting no impact).

Conclusion: Our study documents the overall deterioration of health behaviours during the early stages of the COVID-19 pandemic. To minimize long-term harm to the Canadian population's health, the results highlight the need to tailor interventions, especially for younger Canadians, and the importance of mitigating financial impacts, which are linked to negative changes in health behaviours.

RéSUMé: OBJECTIFS: La pandémie de COVID-19 perturbe profondément la vie quotidienne au Canada. Notre étude évalue les changements survenus dans les comportements de santé aux premiers stades de la pandémie et examine les disparités sociodémographiques associées à ces changements. MéTHODE: Nous analysons les données sur les adultes de 25 ans et plus (N = 4 383) tirées de la Série d’enquêtes sur les perspectives canadiennes 1 : Répercussions de la COVID-19 (SEPC-COVID) d’usage public. Des modèles de régression multinomiale permettent d’évaluer l’association entre les caractéristiques démographiques et socioéconomiques et les augmentations ou les diminutions de six comportements de santé : usage de l’alcool, du tabac et du cannabis, consommation d’aliments vides et temps passé devant la télévision et sur Internet. RéSULTATS: Nos constatations varient entre ces six comportements, mais dans l’ensemble, il y a eu une augmentation des comportements de santé négatifs : 14 % des Canadiens adultes ont dit avoir accru leur usage de l’alcool (IC de 95 % = 0,12, 0,15), 25 % ont accru leur consommation d’aliments vides (IC de 95 % = 0,23, 0,27), et plus de 60 % ont accru leur temps d’écran (62 %, IC de 95 % = 0,60, 0,65 pour la télévision et 66 %, IC de 95 % = 0,63, 0,68 pour Internet). Les jeunes adultes et les adultes nés au Canada étaient plus susceptibles d’avoir accru leurs comportements de santé négatifs que les adultes âgés et ceux ayant immigré au Canada. Les adultes ayant dit subir des contrecoups financiers de la COVID-19 étaient plus susceptibles d’avoir accru tous leurs comportements de santé négatifs (p. ex., pour la consommation accrue d’aliments vides, le rapport de risque relatif [RRR] = 1,81, IC de 95 % = 1,49, 2,20, comparativement au groupe n’ayant pas subi de contrecoups financiers). CONCLUSION: Notre étude décrit la détérioration globale des comportements de santé aux premiers stades de la pandémie de COVID-19. Pour réduire les torts que cela peut causer à long terme à la santé de la population canadienne, il faut, selon les résultats, adapter les interventions, surtout aux jeunes Canadiens, et atténuer les contrecoups financiers de la pandémie, qui sont liés à des changements négatifs dans les comportements de santé.
