Socio-economic status and ethnic background are recognized as predictors of risk for the development of obesity in childhood. The present review assesses the effectiveness of treatment for children according to their socio-economic and ethnic background. Sixty-four systematic reviews were included, from which there was difficulty reaching general conclusions on the approaches to treatment suitable for different social subgroups. Eighty-one primary studies cited in the systematic reviews met the inclusion criteria, of which five directly addressed differential effectiveness of treatment in relation to social disparities, with inconsistent conclusions. From a weak evidence base, it appears that treatment effectiveness may be affected by family-level factors including attitudes to overweight, understanding of the causes of weight gain and motivation to make and maintain family-level changes in health behaviours. Interventions should be culturally and socially sensitive, avoid stigma, encourage motivation, recognize barriers and reinforce opportunities and be achievable within the family's time and financial resources. However, the evidence base is remarkably limited, given the significance of social and economic disparities as risk factors. Research funding agencies need to ensure that a focus on social disparities in paediatric obesity treatment is a high priority for future research.
