Better health indicators of FitSpirit participants meeting 24-h movement guidelines for Canadian children and youth

摘要

This study aims to determine the proportion of girls who meet the recommendations for moderate-to-vigorous physical activity (MVPA), screen time and sleep duration among FitSpirit participants and evaluate the associations of these recommendations with perceived health-related quality of life (QOL), perceived health, physical activity (PA), self-efficacy and body mass index. Cross-sectional analyses of FitSpirit data were performed. All variables were collected through an online questionnaire. The proportion of girls meeting all recommendations was 2.2, while 72.5 met either one or two and 25.4 met none. A greater percentage of girls with ≥3 years in FitSpirit met MVPA and sleep recommendations combined when compared with fewer years (12.9 vs. 1.7 with 1 year; vs. 10.1 with 2 years; p<0.05). Meeting the combinations of MVPA and screen time (β = 0.19, 95 CI = 0.40, 1.68), MVPA and sleep (β = 0.20, 95 CI = 0.27, 1.04) and all three combined (β = 0.17, 95 CI = 0.33, 1.71) was the most significant predictors of better perceived QOL. Respecting MVPA recommendations predicted a better perceived health (β = 0.18, 95 CI = 0.18, 0.87) while girls who slept as recommended had a better PA-related self-efficacy (β = 0.23, 95 CI = 0.51, 2.11). Not meeting any recommendation was associated with inferior PA-related self-efficacy (β = 0.32, 95 CI = - 3.03, - 1.21). Lastly, meeting MVPA and sleep recommendations was significantly associated with lower body mass index z-scores (β = - 0.14, 95 CI = -1.16, -0.11). There was a small percentage of girls following all of the recommendations. Furthermore, meeting individual and combined recommendations was associated with better perceived QOL and health, PA self-efficacy as well as healthier body mass index z-score.
