Childhood overweight and obesity intervention: Effectiveness of a programme based on parents as agents of change

A randomized controlled trial comparing Treatment-As-Usual (TAU) and Group Lifestyle Triple P (GLTP) vs TAU only to evaluate the effectiveness of GLTP in a sample of parents of overweight/obese children aged 5 to 10 recruited from a university hospital: short and long-term (4 and 10 months after baseline) effects on child’s anthropometric measures, body composition, dietary behaviour and physical activity levels, behaviour problems and quality of life; parents' psychological symptoms, perception of child weight-related problem behaviours, general parenting practices, specific parenting practices regarding feeding and physical activity, and perception of change

Design outcomes

Primary

Measure	Time frame
The study includes three assessment time points for both intervention and control conditions at baseline, 4 and 10 months after baseline. The following primary outcomes will be assessed at each time point: 1. Child’s anthropometric measures including height, using a SECA stadiometer, weight, using an Inbody 270 scale, and waist and arm circumferences using a SECA measuring tape 2. Child's body composition, body fat percentage and lean body mass percentage, evaluated using an Inbody 270 scale 3. Child's dietary behaviour, obtained by parents’ report on a three-day food intake diary and by parent’s report on child’s intake frequency for specific foods and beverages 4. Child’s physical activity level, obtained by each child wearing a wGT3X-BT Actigraph Accelerometer for 5 days	—

Secondary

Measure	Time frame
The study includes three assessment time points for both intervention and control conditions at baseline, 4 and 10 months after baseline. The following secondary outcomes will be assessed at each time point: 1. Parents' perception of child's weight-related problem behaviours and self-efficacy in managing such behaviours, assessed using the Lifestyle Behaviour Checklist (LBC) 2. Parents’ comprehensive feeding practices, assessed using the Comprehensive Feeding Practices Questionnaire (CFPQ) 3. Physical activity parenting practices, assessed using the Physical Activity Parenting Practices (PAPP) questionnaire 4. Parenting styles and practices, assessed using the Alabama Parenting Questionnaire (APQ) and the Parenting Scale (PS) 5. Parents’ treatment self-regulation, assessed using the Treatment Self-Regulation Questionnaire (TSRQ) 6. Parents’ agreement or conflict on parenting practices, assessed using the Parent Problem Checklist (PPC) 7. Parents' perception of the child's quality of life, assessed using the EQ-5D-Y and the Kidscreen 8. Parents' perception of the child’s difficulties and strengths, assessed using the Strengths and Difficulties Questionnaire (SDQ) 9. Parents' recall on parents and child healthcare utilisation and productivity losses assessed using a questionnaire adapted from the TiC-P The following data will be collected at baseline: 1. Family sociodemographic characteristics collected using a questionnaire 2. Parents' anxiety, depression, and stress, assessed using the Depression, Anxiety and Stress Scales (DASS-21) Participants of the intervention condition will also provide information on the following: 1. Helpful aspects of the intervention, assessed using an adapted version of the Helpful Aspects of Therapy (HAT) interview, at the middle and the end of the GLTP intervention 2. Perception of family lifestyle changes, assessed using an interview developed for this purpose, at the end of the GLTP intervention 3. Perception of satisfaction with t	—
