P758 Prevalence of moderate to vigorous physical activity and sedentary time in adolescents with inflammatory bowel disease: knowing and doing
Notice bibliographique
Résumé
The importance of physical activity in the prevention of chronic inflammatory diseases has been well established. In fact, it has been shown that higher levels of exercise were associated with reductions in inflammatory serum markers. Therefore, physical activity might be a protective factor against occurrence and progression of inflammatory bowel diseases (IBD). However, children with IBD tend to be less active than their healthy peers. The Canadian 24-H Movement Guidelines for Children and Youth recommend an average daily moderate-to-vigorous physical activity (MVPA) of at least 60 min 7 days a week. The primary aim was to evaluate the prevalence of MVPA in Canadian children with IBD when compared with their healthy Canadian peers. The secondary aims were to assess the prevalence of sedentary behaviour in paediatric IBD and the knowledge about the Canadian MVPA guidelines. Between June and November 2018, children with IBD, age ≥12 years, were prospectively surveyed. Physical Activity was assessed using the Canadian Health Measure Survey Children-Physical Activity Questionnaire, filled out during outpatient visits. Responses were converted into metabolic equivalents of tasks (METS) by using validated tables. Activity with METS between 3 and 6 was classified as moderate intensity and above 6 as vigorous intensity. The proportion of children with at least 1 h daily of MVPA was measured and compared with Canadian data in healthy children. We included 121 patients (52 females; mean (SD) age 15.5 (1.6) years); 84 diagnosed(69.4%) with Crohn’s disease(CD) and 29(24.0%) with ulcerative colitis(UC). Of these, 74.4% were in remission according to the Pediatric Crohn Disease Activity Index or Pediatric ulcerative colitis Activity Index(score ≤10). The prevalence of self-reported physically active patients was 83.5%. In addition, 78.5% claimed that physical activities in the previous week made them sweat and breathe harder. Yet, only 30.6% reached the Canadian physical activity target, which is close to the 35.0% MVPA among healthy Canadian children. The median (IQR) MVPA duration/day was 34.0 min(14.0 to 66.0) and the median (IQR) daily sedentary duration was 5.7 h (3.0 to 8.0). Furthermore, 45.7% of the patients claimed that they discussed the significance and benefits of MVPA with their teachers or doctors, but only 12% were aware of the national target and gave the correct time. Our study showed a low prevalence of MVPA in Canadian children with IBD. The recommended target among this population is far from being achieved. Likely explanations might be the excessive screen time of adolescents and limited promotion of MVPA potential benefits in this population with chronic diseases by healthcare providers.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
