Inclusion criteria
Inclusion criteria: The target population of the proposed study will be physically inactive middle-aged adults (aged 40–64 years) with central obesity in Hong Kong. This particular age group is chosen as the prevalence of central obesity generally increased with age according to the Population Health Survey 2020-22 (2). Physical inactivity will be defined as having less than 3 days of 30-minute moderate-intensity physical activity per week and will be objectively assessed using a device-based measure (i.e. activPAL accelerometer) (3). Central obesity is defined as having a waist circumference 90 centimeters (cm) or above for men and 80 cm or above for women (2). Furthermore, a waist-to-hip ratio at 0.90 or above for men and 0.85 for women also signify centrally obese.
