Education-related relative inequality in non communicable disease risk factors among adults aged 18 or higher in 48 low- and middle-income countries, World Health Survey 2002-04. The relative index of inequality shows education-related inequality in prevalence of current daily smoking, low fruit and vegetable consumption, physical inactivity, and heavy episodic alcohol drinking, among men and women aged 18 or higher, living in 48 low- and middle-income countries that participated in the 2002–04 World Health Survey. Individuals were cumulatively ranked by descending education level, and prevalence ratios compared risk factor prevalence in the least educated group to risk factor prevalence in the most educated group. Brackets indicate 95% confidence intervals. Model 1 data are adjusted for country of residence and age; Model 2 data are adjusted for country of residence, age, marital status, urban/rural area and wealth.
