摘要

Objective: To assess the physical activity and sedentary behaviors of a sample of Latino children in London, Ontario, Canada. Methods: Seventy-four Latino children (54.1% male; mean age = 11.4) completed self-report questionnaires related to physical activity and sedentary behaviors. A subset of children (n = 64) wore Actical (Mini Mitter, Respironics) accelerometers for a maximum of four days. Results: Latino children self-reported moderate levels of physical activity (i.e., mean score of 2.8 on 5-point scale). Accelerometer data revealed that children spent an average of 50.0 min in moderate-to-vigorous physical activity (MVPA; 59.2 min on weekdays and 50.6 min on weekend days) and were sedentary for an average of 8.4 h (508.0 min) per day (533.5 min on weekdays and 497.7 min on weekend days). Children reported spending an average of 3.8 h (228 min) daily in front of screens—1.7 h (102 min) watching television, 1.2 h (72 min) on the computer, and 0.9 h (54 min) playing video games. Conclusions: This feasibility project provided a preliminary account of objectively measured daily physical activity and sedentary time among a sample of Latino children in Canada, as well as insight into the challenge of measuring these behaviors. Sedentary behavior reduction techniques should be explored and implemented in this young population, along with strategies to promote adherence to accelerometer protocols.
