Abstract

Objectives We assessed socioeconomic inequalities in relation to acute myocardial infarction (AMI) incidence among major ethnic groups in The Netherlands.

Methods A nationwide register-based cohort study was conducted (n=2 591 170) between 1 January 1998 and 31 December 2007 among ethnic Dutch and migrant groups from Suriname, Netherlands Antilles, Indonesia, Morocco and Turkey. Standardised household disposable income was used as a proxy for socioeconomic position. Cox proportional hazard models were used to estimate the socioeconomic inequalities in AMI incidence.

Results Among ethnic Dutch, the AMI incidence was higher in the low-income group than in the high-income group: adjusted HRs were 2.05 (95% CI 2.00 to 2.10) for men and 2.33 (95% CI 2.23 to 2.43) for women. Importantly, similar socioeconomic inequalities in AMI incidence were also observed in all minority groups, with the low socioeconomic group having a higher AMI incidence than the high socioeconomic group: adjusted HR ranging from 2.07 (95% CI 1.26 to 3.40) in Moroccans to 2.73 (95% CI 1.55 to 4.80) in Antilleans in men; and from 2.17 (95% CI 1.74 to 2.71) in Indonesians to 3.88 (95% CI 2.36 to 6.38) in Turks in women.

Conclusions Our findings demonstrate socioeconomic inequalities in AMI incidence in migrant groups and suggest a convergence towards the Dutch general population. If the AMI incidence rates of the low socioeconomic group could be reduced to the level of the high socioeconomic group, this would represent a major public health improvement for all ethnic groups.
