Obesity prevalence is disparate based on accommodation, gender, education, and other socioeconomic characteristics in Iran.• Obesity and inequality are linked through immediate and intermediate causes. Inequality in access to healthy foods, physical activity facilities, and health care is the immediate cause of this inequality. Of course, these immediate factors result from intermediate factors, including inequality against women, children, and refugees, and inequality in access to information and education, and financial resources.• Obesity control policies should pay more attention to the fundamental promotors of obesity inequality. Policymakers should implement equity-oriented obesity control policies such as taxing unhealthy foods, subsidizing healthy foods, providing healthy and free meals in schools, especially in disadvantaged areas, and providing nutrient-rich foods to low-income families. Also, environmental re-engineering to increase opportunities for physical activity, especially in marginalized and disadvantaged areas of the country, should be considered• .
