Pre-post evaluation of a weight management service for families with overweight and obese children, translated from the efficacious lifestyle intervention Parenting, Eating and Activity for Child Health (PEACH).

ABSTRACT

Parenting, Eating and Activity for Child Health (PEACH) is a multi-component lifestyle intervention for families with overweight and obese children. PEACH was translated from an efficacious randomised-controlled trial (RCT) and delivered at scale as PEACH Queensland (QLD) in Queensland, Australia. The aim of this study is to explore pre-post changes in parenting, and child-level eating, activity and anthropometry, in the PEACH QLD service delivery project. PEACH QLD enrolled 926 overweight/obese children (817 families). Pre-programme evaluation was completed for 752 children and paired pre-post-programme evaluation data were available for 388 children. At baseline, children with pre-post-programme data were (mean) 8·8 years old, and at follow-up were 9·3 years old, with mean time between pre-post-programme measures of 0·46 years. Outcomes reflected each domain of the PEACH programme parenting, eating behaviour of the child and activity behaviours (means reported). Parents reported improvements in parenting self-efficacy (3·6 to 3·7, P=0·001). Children had improved eating behaviours eating more daily serves of vegetables (2·0 to 2·6, P=0·001) and fewer non-milk sweetened beverages (0·9 to 0·6, P=0·001) and discretionary foods (2·2 to 1·5, P=0·001). Children spent more time in moderate-to-vigorous physical activity (86 to 105 min/d, P=0·001) and less time in sedentary screen-based behaviours (190 to 148 min/d, P=0·001). Consequently, there were significant improvements in mean BMIz (-0·112; P<0·001) and weight status (healthy weight/overweight/obese/morbidly obese prevalence from 0/22/33/45 % to 2/27/34/37 %, P<0·001). When delivered at scale, PEACH remains an effective family-based, multi-component, lifestyle weight management programme for overweight and obese children whose families engage in the programme.
