Purpose: The aim of this study was to examine the factors that influence compliance and practical utility of a continuous wear protocols for activPAL™ among adolescents. Methods: Seven hundred and fifty-five (11–18 y; 50.6% girls) students wore the waterproof activPAL™ for 7 consecutive days. The effects of factors such as weather and practical strategies on compliance were assessed. Students were asked to note reasons for removing it in a log. After the 7-day period, students anonymously completed a practical utility questionnaire. Results: The final sample used to analyze compliance contained 588 available data points; 72.4% met the validity criteria, which were ≥4 valid days. Rainfall was inversely associated with total wear time, whereas using alcohol pads and cartoon stickers during the application were positively associated with total wear time. Sweating (25.2%) and skin irritation (39.0%) were the most reasons for 290 removal episodes by 235 students. The 131 questionnaires showed that 80.1% regarded the continuous wear period as too long and encountered problems, and 55% would rather not wear it again. Conclusion: Rainy weather affected girls’ compliance with the continuous wear protocol for activPAL™. Skin irritation and sweat-induced inadvertent drops caused removal. Future studies should investigate more user-friendly protocols.

Hong Kong’s 2016 Report Card on Physical Activity (PA) for Children and Youth is the first evidence-based synthesis of various indicators related to individual behaviors that contribute to overall PA levels, settings and sources of influence, and strategies and investments in Hong Kong.
Following a standardized protocol, currently best available data for Hong Kong youth were collated and evaluated by an expert consensus panel on 9 indicators (5 activity behaviors and 4 influences on these behaviors).
Less than half of the children and youth met the recommended PA level. As a result, a D grade was given for Overall PA levels. Organized Sport Participation and Active Transportation received grades of C- and B, respectively. Sedentary Behaviors and School scored a C grade. Community and the Built Environment scored a grade of B. Family Influence received as low a score as Overall PA (D). Active Play and Government were not graded due to incomplete data.
PA levels are low and sedentary behaviors are high for children and youth in Hong Kong. Promising policies exist in schools and features of community and the built environment are favorable. Increasing family support should be emphasized for future PA promotion.
