Alcohol drinking characteristics in male weekly drinkers in 2004–8 and 2013–4, by health-related risk factor index. Prevalence and mean were adjusted for age and regions. Size of boxes is proportional to the sample size of the respective risk factor index group. Error bars are 95% confidence intervals. Mean consumption per session (g/session) and heavy episodic drinking was based on alcohol intake data reported on the last time the participants drank. Heavy episodic drinking is defined as drinking > 60 g of pure alcohol in one session for men. Risk factor index was derived by summing the individual scores of each of the four risk factors (0 if no, 1 if yes): regular smoking, lack of daily fruit intake, hypertension, low physical activity. All men at baseline (n = 210,259) and resurvey (n = 9569) were included in (a). All male weekly drinkers at baseline (n = 69,904) and resurvey (n = 2732) were included in (b-d)
