One thousand and twenty Polish men and women and 1,011 Swedish men and women aged 50 and recruited through primary health care took part in a survey relating to their knowledge of health-related behaviour, attitudes to health-related behaviour and self-reported risk behaviour. The results reveal that Poles know as much about cardiovascular risk factors as Swedes, but that Swedes feel that it is more important to change their dietary habits and to influence factors in the working environment to avoid the risk of developing CVD than did Poles. Swedes also displayed less risk behaviour than Poles and more Swedes than Poles had successfully stopped smoking. These findings suggest that differences in stages of health-related behavior that have previously been observed at an individual level may sometimes also be discerned at a national level.
