Study	Design & quality appraisal 1	Setting & participants	Study aim	Intervention 2	Inequality 3	Summary results 4 ↑ = increase ↓ = decrease ↔ = no change		Impact on inequalities in obesity 5
Sanigorski et al 2008 [55]	Quasi-experimental including cluster RCT; 3 year follow-up; Final sample = 1807; Quality = Strong	Community (environmental and policy), Australia; 4-12 years; ≈ 50% girls	Reduce prevalence of childhood obesity	Nutrition and physical activity intervention; Prevention: Community capacity-building programme. Intervention included all manner of things. Targeted a variety of diet, physical activity and sedentary behaviours	Universal: No association between intervention effect and SES; SES associated with weight gain in control group	Waist circumference	↓	+

¹Global Quality appraisal from EPHPP (16); ²Prevention or treatment intervention; ³Targeted/Universal approach to inequality; ⁴p < 0.05.This is the relative mean differences between intervention and control at follow-up; ⁵+ positive intervention effect so it reduces obesity-related outcomes in low SES groups or reduces the SES gradient in obesity-related outcomes, 0 no intervention effect or no effect on SES gradient in obesity-related outcomes; SES = Socioeconomic status; BMI = Body mass index.
