Uptake of child weight management (CWM) support is typically low, and services are not available in all areas. Extended brief interventions (EBIs) have been proposed as an affordable way to provide enhanced support, at a level between one-off brief advice and intensive CWM programmes. This rapid systematic review sought to synthesise evidence on the efficacy of EBIs for weight management and obesity prevention in children (2-18 years). Embase and Web of Science were searched from January 2012 to January 2022. Nineteen studies, reporting on 17 separate EBIs, were included. The quality of studies was variable and the EBIs were heterogeneous. The majority of EBIs (n=14) were based on motivational interviewing. Five of the included studies reported significant improvements in parent or child determinants of health behaviour change. However, robust measures of behavioural determinants were rarely used. No studies reported significant positive effects on child weight. No clear patterns in outcomes were identified. There is currently insufficient evidence for EBIs to be adopted as part of CWM services. To improve the evidence base, EBIs that are currently being implemented by local health services, should be evaluated to establish the most effective content, how it should be delivered and by whom.
