¹Model  =  education (three levels)*wealth quintile (continuous) + age group + urban/rural residence + parity.

²ORs represent the effect of an increase in one wealth quintile on the odds of obesity within each education level.

³Estimates for education not shown.

⁴Test of whether the wealth effects differ by education level.
