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.",[27,28,29,30],"Sedentary Behaviors","Physical Inactivity","Child Health","Lifestyle (Sedentary Behavior and Physical Activity)",[32,33,34,35,36],"sedentary behaviour","physical activity","school-based intervention","family-based intervention","randomized controlled trial","NOT_YET_RECRUITING","2026-04-05",{"date":40,"type":41},"2026-04-13","ACTUAL",{"date":43,"type":21},"2026-11-30",{"date":45,"type":21},"2028-12-02",{"name":47,"class":48},"Instituto Politécnico de Setúbal","OTHER",1,{"id":51,"slug":52,"hasResults":11,"nctId":53,"briefTitle":54,"officialTitle":55,"acronym":56,"eligibilityCriteria":57,"healthyVolunteers":17,"sex":18,"minAge":58,"maxAge":59,"enrollmentInfo":60,"targetDuration":4,"studyType":22,"phases":62,"briefSummary":63,"conditions":64,"keywords":66,"overallStatus":72,"whyStopped":4,"lastUpdateSubmitDate":73,"lastUpdatePostDateStruct":74,"startDateStruct":76,"completionDateStruct":78,"leadSponsor":80,"locationsCount":49},"100503935","myback---a-behavior-change-informed-exercise-program-to-prevent-low-back-pain-recurrences-100503935","NCT05841732","MyBack - A Behavior Change Informed Exercise Program to Prevent Low Back Pain Recurrences","MyBack - Effectiveness and Implementation of a Behavior Change Informed Exercise Program to Prevent Low Back Pain Recurrences: a Hybrid Effectiveness-implementation Randomized Controlled Study","MyBack","Inclusion Criteria:\n\n* Recovered (within the last 3 months) from an episode of non-specific LBP (with or without leg pain and of any duration)\n* Recovery from an LBP episode is defined as having a pain score of \"0\" or \"1\" on a 11-point Numeric Pain Rating Scale for, at least, 30 consecutive days\n* Age between 18 and 65 years;\n* Read and speak the Portuguese language;\n* Having a mobile phone capable of receiving and sending text messages;\n* No medical contraindication to exercise.\n\nExclusion Criteria:\n\n* Diagnosis, or symptoms consistent with, severe depression or other psychiatric condition,\n* Pregnancy\n* Spinal surgery in the last 6 months","18 Years","65 Years",{"count":61,"type":21},186,[24],"Low Back Pain is a common heath condition with high rates of recurrence and huge associated costs.
