Abstrakt: Objectives: Low adherence to 24-hour Movement Guidelines for moderate-to-vigorous physical activity, screen time and sleep during adolescence is well documented, yet recommendations regarding light physical activity, vigorous physical activity and muscle and bone strengthening activities have received less attention. This study comprehensively examined adherence to seven components of the movement guidelines in adolescents and analysed disparities by age and gender.
Design: Longitudinal study with two assessment time points, separated by one year.
Methods: Data were collected in 216 New Zealand adolescents aged 12-17 years, and at 1-year follow-up in 167 participants (77 %), using thigh-worn accelerometers and a self-reported diary.
Results: Adherence rates were 3.7 % for moderate-to-vigorous physical activity, 13.0 % for screen time, 44.0 % for sleep, 14.4 % for light physical activity, 36.1 % for vigorous physical activity, 30.6 % for bone and muscle strengthening activities, and 4.6 % for consistent bedtimes. Less than 1 % of participants met all seven recommendations. Adherence was disproportionately low amongst older adolescents for light physical activity, screen time and consistent bedtimes, and amongst girls for vigorous physical activity and muscle and bone strengthening activities. Over one year, adherence declined for light physical activity (15.0 %-7.2 %) and screen time (15.6 %-6.0 %).
Conclusions: New Zealand adolescents are not adhering to recommendations for a healthy balance of time use outlined in the 24-h Movement Guidelines. These findings highlight the need for adolescents to increase their daily movement, with a particular focus on light physical activity amongst older adolescents and muscle and bone strengthening activities amongst girls.
