Increasing inequality in ischaemic heart disease morbidity among employed men in Denmark 1981-1993: the need for a new preventive policy.
BACKGROUND
In the mid 1980s European governments committed themselves to the WHO goal 'reduced inequality in health by year 2000' according to which inequality in health should be reduced by 25% by the year 2000. The study aim is to estimate the time trend in relative risk due to ischaemic heart disease (IHD) morbidity in employment status groups in Denmark in the period from 1981 to 1993 and to recommend a strategy to reduce inequality in health.


METHODS
The study dealt with change in relative risk of IHD in main employment status AND groups as measured in three successive cohorts. The cohorts were defined as all


METHODS
gainfully employed men in Denmark as of 1 January 1981, 1986 and 1991, respectively. Information on employment was retrieved for the three previous years. The cohorts were followed for first admissions with IHD as the principal cause during 5, 5, and 3 years respectively.


RESULTS
Managers and white collar workers had an average or low and decreasing relative risk while male blue collar workers had a high and increasing relative risk. Thus the social inequality in IHD is rapidly increasing. Some occupational groups are known to be at high risk. Some of these high-risk groups, such as bus drivers, even have an increasing relative risk.


CONCLUSIONS
The general health education has been successful in the prevention of IHD in the high-status groups but has failed to reduce the risk among blue collar workers. Preventive measures against IHD should focus on occupational groups at high, increasing risk and the measures should tailor to their 'subculture.'
