Abstract

Purpose: The clustering of specific health-related behaviours was examined among adolescents.
Methods: In 2005, cluster analysis was conducted to identify homogeneous groups of Toronto, Ontario, 14- to 17-year-old adolescents (n=445) with similar behaviour patterns according to self-reported measures of moderate to vigorous physical activity (metabolic equivalent [MET] hours a week of MVPA), sedentary behaviours (viewing television or videos, using a computer/the internet, doing homework, and talking with friends), fruit and vegetable consumption, and alcohol consumption.
Results: Three clusters of adolescents were identified: “active, high screen-time users,” “active, low screen-time users,” and “less active, least frequent drinkers.”
Conclusions: Identifying clusters of adolescents with similar health-related behaviour patterns suggests that researchers and practitioners should develop and implement interventions tailored to specific clusters.

Résumé

Objectif: Examiner le regroupement de comportements précis en lien avec la santé chez les adolescents.
Méthodes: En 2005, une analyse de regroupement a été menée afin d'identifier des groupes homogènes d'adolescents de 14 à 17 ans de Toronto en Ontario (n = 445) possédant des modèles comportementaux similaires selon des mesures rapportées par les participants quant à l'activité physique d'intensité modérée à élevée (équivalent métabolique [MET] pour les heures/semaine d'APME), aux comportements sédentaires (regarder la télévision ou des vidéos, utiliser un ordinateur/surfer dans Internet, faire des devoirs et parler avec des amis), à la consommation de légumes et fruits, et à la consommation d'alcool.
Résultats: Trois groupes d'adolescents ont été identifiés : « actifs passant beaucoup de temps devant un écran », « actifs passant peu de temps devant un écran » et « moins actifs consommant moins fréquemment de l'alcool ».
Conclusions: L'identification de groupes d'adolescents possédant des modèles comportementaux en lien avec la santé similaires suggère que les chercheurs et les cliniciens devraient mettre au point et implanter des interventions sur mesure pour divers groupes.
