- Registration Number
- NCT05521490
- Lead Sponsor
- The University of Hong Kong
- Brief Summary
The aim of this study is to examine the effects of a kindergarten-based, parent-involved intervention during the upper kindergarten year (K3) on physical activity and physical fitness in preschool children.
- Detailed Description
This study is a two-arm cluster randomized controlled trial. Kindergartens will be randomly allocated to two groups: the usual care group and the intervention group. The usual care group will continue with their usual curriculum, which includes 30 minutes of daily physical activity stipulated by the Hong Kong SAR Government's Education Bureau. The intervention group will receive an additional 2.5 hours of physical activity per week in addition to the stipulated 30 minutes of daily physical activity. Outcome measures will be examined at baseline, 10 months (post-intervention), and 16 months (follow-up).

Group Intervention Description Usual Care Control Usual Care Control Children allocated to the control group will continue with their usual curriculum, which includes the stipulated 30 minutes of daily physical activity. Physical Activity Enhanced Curriculum Physical Activity Enhanced Curriculum Children allocated to the intervention group will receive enhanced physical fitness and healthy lifestyle education and a physical activity enhanced curriculum during their school year.
- Primary Outcome Measures
Name Time Method Change in Cardiorespiratory Fitness Baseline and 10 months Cardiorespiratory fitness will be assessed using the 20-meter shuttle run test.
Change in Physical Activity Baseline and 10 months Physical activity will be assessed using an actigraph device with a three-axis accelerometer.
- Secondary Outcome Measures
Name Time Method Change in Cardiorespiratory Fitness Baseline and 16 months Cardiorespiratory fitness will be assessed using the 20-meter shuttle run test.
Change in Muscle Power Baseline, 10 months, and 16 months Muscle power will be assessed using a vertical jump and a stationary long jump test.
Change in Physical Activity Baseline and 16 months Physical activity will be assessed using an actigraph device with a three-axis accelerometer.
Change in Agility Baseline, 10 months, and 16 months Agility will be assessed using a 4 x 10-meter shuttle run test.
Change in Body Mass Index Baseline, 10 months, and 16 months Weight and height will be assessed using a calibrated electronic digital weighing scale and stadiometer respectively.
Change in Theory of Planned Behavior Scale Score Baseline, 10 months, and 16 months Theory of Planned Behavior Scale (TPBS) will be used to assess the children's social cognitive beliefs of health and physical activity behavior. The items in TPBS will be answered on a 3-point Likert scale with a higher score corresponding to a greater willingness to engage in the mentioned behaviors.
Change in Sedentary Behavior and Screen Time Baseline, 10 months, and 16 months Sedentary behavior and screen time will be assessed using a 7-day activities logbook and accelerometer data.
Change in Muscular Strength Baseline, 10 months, and 16 months Muscular strength will be assessed using a handgrip dynamometer.
Change in Waist Circumference Baseline, 10 months, and 16 months Waist circumference will be assessed using an inelastic measuring tape to the nearest 0.1cm.
Change in Flexibility Baseline, 10 months, and 16 months Flexibility will be assessed using the sit-and-reach test.
Change in Balance Ability Baseline, 10 months, and 16 months Balance ability will be assessed by the number of successful steps performed on a balance beam.
Change in Body Fat Baseline, 10 months, and 16 months Body fat will be assessed using a bioelectrical impedance-based multi-frequency segmental body composition analyzer (MC780, Tanita, Japan).
Change in Fat-Free Mass Baseline, 10 months, and 16 months Fat-free mass will be assessed using a bioelectrical impedance-based multi-frequency segmental body composition analyzer (MC780, Tanita, Japan).
Change in Kiddy-KINDL Baseline, 10 months, and 16 months Kiddy-KINDL will be used to assess the health-related quality of life in children.
Change in Early Development Instrument Baseline, 10 months, and 16 months Early Development Instrument (EDI) will be used to assess the children's general well-being.
Change in Treatment Self-Regulation Questionnaire Score Baseline, 10 months, and 16 months Treatment Self-Regulation Questionnaire (TSRQ) will be used to assess the children's autonomous motivation and beliefs on active healthy lifestyles. The items in TSRQ will be answered on a 3-point Likert scale with a higher score corresponding to greater autonomous motivation.
