To gain insight into the prevalence of diabetes mellitus and cardiovascular disease among Turkish and Moroccan immigrants in the Netherlands.
Secondary analysis of data from a cross-sectional study in 1999/’00.
The prevalence of self-reported diabetes and cardiovascular disease was studied in a sample of 743 Turkish, 641 Moroccan and 537 ethnic Dutch persons aged 35 to 74 years from the population of Amsterdam, the Netherlands, using an oral questionnaire. Ethnic differences in the prevalence of diabetes and cardiovascular disease were studied by logistic regression analysis controlling for age, sex and educational level. Further, in the case of diabetes, we examined whether or not the differences could be explained by overweight and physical inactivity, and in the case of cardiovascular disease we investigated the relationship with smoking and diabetes. In addition, the association between diabetes and cardiovascular disease was investigated.
The Turkish and Moroccan population reported diabetes more often than did the ethnic Dutch (12.3, 12.4 and 3.0, respectively). The differences were still present after controlling for sex, age, educational level, overweight and physical inactivity. Cardiovascular disease was more prevalent among the Turks (10.6) than among the indigenous Dutch population (5.0), but this was not true for the Moroccans (5.4). The difference between Turkish and ethnic Dutch people still persisted after controlling for eductional level, overweight, physical inactivity, smoking and diabetes. The association between diabetes and cardiovascular disease was consistent for all groups studied.
The prevalence of diabetes was higher among Turkish and Moroccan immigrants than among the indigenous Dutch population. Cardiovascular disease was more prevalent among the Turks, but not among the Moroccans. The association between diabetes and cardiovascular disease was consistent for all three ethnic groups.
