Addressing the potential adverse effects of school-based BMI assessments on children

Introduction. Do child obesity prevention research and intervention measures have the potential to generate adverse concerns about body image by focussing on food, physical activity and body weight? Research findings now demonstrate the emergence of body image concerns in children as young as 5 years. In the context of a large school-community-based child health promotion and obesity prevention study, we aimed to address the potential negative effects of height and weight measures on child wellbeing by developing and implementing an evidence-informed protocol to protect and prevent body image concerns. fun 'n healthy in Moreland! is a cluster randomised controlled trial of a child health promotion and obesity prevention intervention in 23 primary schools in an inner urban area of Melbourne, Australia. Body image considerations were incorporated into the study philosophies, aims, methods, staff training, language, data collection and reporting procedures of this study. This was informed by the published literature, professional body image expertise, pilot testing and implementation in the conduct of baseline data collection and the intervention. This study is the first record of a body image protection protocol being an integral part of the research processes of a child obesity prevention study. Whilst we are yet to measure its impact and outcome, we have developed and tested a protocol based on the evidence and with support from stakeholders in order to minimise the adverse impact of study processes on child body image concerns.
