Social determinants of obesity and effects of the community built environment remain poorly understood in developing nations. We synthesized literature on socio-economic (SES) gradients and income inequality effects on health and analyzed data from China Health and Nutrition Survey (N=9,586) to understand how multilevel social determinants of obesity varied by built environments assessed by fast food restaurants and sports facilities. We found that at the individual-level, obesity was positively associated with income and wealth but negatively associated with education and manual occupation. At the community-level, obesity was negatively associated with income inequality in north regions. SES effects on obesity varied across built environmental contexts; inequality effects on obesity remained significant and consistently negative across contexts. All these social determinants effects were pronounced in communities with the presence of fast food but absence of sports facilities. SES and inequality effects on obesity in China are different from those in developed countries.
