a b. Adjusted educational inequalities in hypertension, diabetes, obesity, and current smoking by survey year for (a) men and (b) women. Period 2005–2013. Model for each outcome includes all main effects and interaction for education and survey. Analyses are adjusted for age and urbanicity. RII > 1 indicates higher prevalence with lower levels of education, RII < 1 indicates lower prevalence with lower levels of education. Significant p values for interactions include: Men, hypertension (p < 0.001); Women, hypertension (p = 0.018) and current smoking (p < 0.001)
