Abstract
OBJECTIVES: While cross-Canada variations in physical activity and weight status have been illustrated, less is known about sedentary behaviour (SB). The aim of this study was to describe various SBs and their correlates among Canadian adults.
METHODS: Cross-sectional data from the 2011–2012 Canadian Community Health Survey included 92,918 respondents aged 20–75+ years, representative of >22 million Canadian adults. TV/video viewing, computer, video game playing and reading time were self-reported. Associations with socio-demographic, health and health behaviour variables were examined.
RESULTS: About 31% of adults reported >2 hours/day TV viewing, while 47% of men and 41% of women reported >5 hours/week computer use, 24% of men and 12% of women reported ≥1 hour/week video game playing, and 33% of men and 46% of women reported >5 hours/week reading; 28% of respondents reported ≥5 hours/day total SB time. Age was the strongest correlate: adults 75+ had 5 and 6 times greater odds respectively of reporting >2 hours/day TV viewing and >5 hours/week reading, but far lesser odds of reporting high computer or video game time, compared to adults 20–24. Other variables associated with specific SBs included gender, marital status, education, occupation, income and immigrant status, as well as BMI, weight perceptions, smoking, diet and physical activity.
CONCLUSION: Common sedentary behaviours were associated with numerous socio-demographic, health and health behaviour characteristics in a large representative sample of Canadians. These correlates differed according to the type of SB. Public health interventions targeting SB should be behaviour-specific and tailored to the population segment of interest.

Résumé
OBJECTIFS: Les écarts transcanadiens dans l’activité physique et le statut pondéral ont été illustrés, mais on en sait moins au sujet des comportements sédentaires (CS). Nous avons cherché à décrire divers CS et leurs corrélats chez les Canadiens adultes.
MÉTHODE: Les données transversales de l’Enquête sur la santé dans les collectivités canadiennes de 2011–2012 ont inclus 92 918 répondants de 20 ans à 75 ans et plus, qui représentaient >22 millions de Canadiens adultes. L’écoute de la télévision/de vidéos, l’usage de l’ordinateur ou de jeux vidéo et le temps de lecture ont été autodéclarés. Nous avons examiné les associations avec les variables sociodémographiques, l’état de santé et les habitudes de santé.
RÉSULTATS: Environ 31 % des adultes ont déclaré >2 heures/jour d’écoute de la télévision, tandis que 47 % des hommes et 41 % des femmes ont déclaré >5 heures/semaine d’usage de l’ordinateur, 24 % des hommes et 12 % des femmes ont déclaré jouer à des jeux vidéo ≥1 heure/semaine, et 33% des hommes et 46 % des femmes ont déclaré lire >5 heures/ semaine; 28 % des répondants ont déclaré avoir ≥5 heures/jour de CS au total. L’âge était le corrélat le plus fort: les adultes de 75 ans et plus avaient une probabilité 5 et 6 fois plus grande, respectivement, de déclarer >2 heures/jour d’écoute de la télévision et >5 heures/semaine de lecture, mais des probabilités beaucoup moindre de déclarer passer beaucoup de temps à l’ordinateur ou à jouer à des jeux vidéo que les adultes de 20 à 24 ans. Les autres variables associées à certains types de CS étaient le sexe, l’état matrimonial, le niveau de scolarité, la profession, le revenu et le statut d’immigrant, ainsi que l’IMC, les perceptions du poids, le tabagisme, le régime alimentaire et l’activité physique.
CONCLUSION: Les comportements sédentaires courants étaient associés à de nombreuses caractéristiques sociodémographiques, d’état de santé et d’habitudes de santé au sein d’un vaste échantillon représentatif de Canadiens. Ces corrélats différaient selon le type de CS. Les interventions de santé publique ciblant les CS devraient être adaptées au comportement et au segment démographique d’intérêt.
