M igrants' health is an important public health issue 1 with growing evidence supporting the role of migration in the development of noncommunicable diseases. [2][3][4] Migrant populations from sub-Saharan Africa (SSA) seem to be affected disproportionately by cardiovascular diseases (CVDs) and related risk factors, including hypertension, obesity, and diabetes mellitus. 5,6 For instance, the prevalence of hypertension in The Netherlands relative to Dutch people is higher in all ethnic minority groups, with the exception of Moroccan women. 7 Evidence from Canada, however, shows better CVD risk profile among migrants than the host population. 8 This shows the importance of diverse factors (including acculturative stress resulting from the feeling of isolation, discrimination, alienation and dislocation, Background-For migrant populations from sub-Saharan Africa, adverse cardiovascular disease (CVD) risk factors have been observed to be higher than found in their home country-based counterparts or among the host populations in high-income countries. Differences in absolute overall CVD risk, however, remain largely unexplained. We, therefore, predicted the differences in 10-year CVD risk among sub-Saharan African migrants (Ghanaians) living in 3 European cities and Ghana. Methods and Results-For 3864 subjects aged 40 to 70 years from the multicenter RODAM study (Research on Obesity and Diabetes Among African Migrants) conducted among Ghanaian adults residing in rural and urban Ghana and 3 European cities (Amsterdam, Berlin, and London), 10-year risk of CVD was estimated using the Pooled Cohort Equations with estimates ≥7.5% defining high CVD risk. Logistic regressions were used to determine the association of migration on CVD risk. Migrant populations carry along disease characteristics, inherited from their place of origin, 11 which affect future risk of CVD. The CVD risk profile among migrant populations, however, may change over time as they get exposed to the factors of their host environment. 12 This results in differences in CVD risk between similar populations residing in different industrialized countries. For instance, Agyemang et al 13 found that people of African descent residing in England had a lower prevalence of type 2 diabetes mellitus than those residing in The Netherlands, and these differences reflected the difference in prevalence of CVDs of their host countries.
14The reasons for these differences are unclear but could include cross-national differences in health behaviors and related factors, such as socioeconomic position, accessibility, and utilization of preventive services. 13,15 CVDs reflect the combined effect of several risk factors, 16 which tend to appear in clusters.17 Current guidelines for CVD risk reduction have, therefore, reiterated the need to assess all risk factors as a more effective basis to deliver CVD prevention interventions.16 Absolute CVD risk estimates, using established risk algorithms, help to determine the probability of a cardiovascular event occurring within a sp...
