MAFF-CRT: Reducing Sedentary Behaviour in Children
Starting soon · Not applicable
Conditions studied: Sedentary Behaviors, Physical Inactivity, Child Health, Lifestyle (Sedentary Behavior and Physical Activity)
In brief
Children today spend many hours sitting at school and at home, often in front of screens. Prolonged sitting in childhood increases the risk of future health problems such as diabetes, heart disease and poor mental wellbeing. MAFF is a simple school-to-home programme that teaches short, practical movement breaks in the classroom and encourages families to repeat them together at home through structured weekly challenges. Over 12 weeks, we will compare classes using MAFF with classes continuing as usual to assess whether children sit less, move more and improve their wellbeing. If effective, MAFF will provide schools and communities with an easy-to-implement toolkit to promote healthier and more active families.
