Relative risk ratios (RRRs) of daily smoking among 20–64-year-olds by education. No clear association was found between daily smoking and education among men in 1990–1994 and among women in 1990–2000. Men revealed inverse relationship between daily smoking and educational level since 1996, but women since 2002. Compared to men with higher education, relative risk of daily smoking (vs non-smoking) was 3.72 (95% CI = 2.45–6.35) times higher among men with secondary education and 5.44 (95% CI = 2.78–10.65) times higher among men with basic education in 1996. RRRs were 2.92 (95% CI = 2.01–4.25) and 4.98 (95% CI 3.12–7.94 in 2010) among men in 2010. Compared to women with higher education, relative risk of daily smoking (vs non-smoking) was 1.88 (95% CI = 1.07–3.31) times higher among women with secondary education and 3.67 times higher (95% CI = 1.66–8.12) among women with basic education in 2002. Respective RRRs were 2.29 (95% CI = 1.65–3.17) and 6.62 (95% CI 4.07–10.76) among women in 2010.
