Cardiovascular risk factors among Russian, Somali and Kurdish migrants in comparison with the general Finnish population

BACKGROUND There is limited information on cardiovascular risk among migrants. We compared cardiovascular risk factors among three major migrant groups in Finland with the general population. METHODS Cross-sectional data from 30- to 64-year-old health examination participants (n = 921) of the Migrant Health and Wellbeing Study (2010-12) were used. Data for comparison with the general Finnish population were obtained from the Health 2011 Study (n = 892). RESULTS Russian men had a similar risk profile to that of the reference group. Kurdish men had lower prevalence of hypertension [prevalence ratio (PR) 0.55, 95% confidence interval (CI) 0.39-0.79] but higher prevalence of dyslipidaemia (PR: 1.12, 95% CI: 1.02-1.24) and hyperglycaemia (PR: 2.61, 95% CI: 1.88-3.64) compared with the reference group. Somali men had lower prevalence of smoking (PR: 0.18, 95% CI: 0.08-0.44), hypertension (PR: 0.55, 95% CI: 0.32-0.97)) and obesity (PR: 0.35, 95% CI: 0.17-0.71) but higher prevalence of hyperglycaemia (PR: 2.59, 95% CI: 1.73-3.86) compared with the reference group. Similar patterns were observed for women, except for higher prevalence of hyperglycaemia among Russian women (PR: 1.95, 95% CI: 1.26-3.01) and obesity among Kurdish and Somali women (PR: 1.41, 95% CI: 1.15-1.72 and PR: 1.68, 95% CI: 1.40-2.03, respectively) compared with the reference group. All migrant women had significantly lower prevalence of smoking than the reference group. CONCLUSIONS There were significant variations in cardiovascular risk profiles of Kurdish and Somali migrants compared with the general population. Differences in cardiovascular risk factors by migrant group need to be taken into account in planning and implementing health promotion strategies.

Contribution of sociodemographic and lifestyle-related factors to the differences in metabolic syndrome among Russian, Somali and Kurdish migrants compared with Finns

BACKGROUND Metabolic syndrome (MetS) is associated with a substantially increased risk for cardiovascular disease and diabetes. We examined the contribution of length of residence, socioeconomic position and lifestyle-related factors to the differences in the prevalence of MetS among migrants compared with Finns. METHODS Cross-sectional data from randomly sampled 30-64year-old health examination participants (318 Russian, 212 Somali, and 321 Kurdish origin migrants) of the Migrant Health and Wellbeing Survey (2010-2012) were used. Health 2011 Survey participants (n=786) were the reference group. RESULTS Compared with Finns, prevalence of MetS was significantly higher among all migrants except for Somali men. Among men, age-adjusted prevalence ratio (PR) of MetS compared with Finns was 1.71, 95% confidence interval (CI) 1.19-2.46 for Russians, PR 0.95 (95% CI 0.54-1.67) for Somali, and PR 2.10 (95% CI 1.51-2.93) for Kurds. Among women, respective PRs were 1.45 (95% CI 1.08-1.97) for Russians, PR 2.34 (95% CI 1.75-3.14) for Somali and PR 2.22 (95% CI 1.67-2.97) for Kurds. Adjustment for sociodemographic and lifestyle-related factors attenuated the differences in MetS among women but not men. CONCLUSIONS Further studies should aim at identifying factors related to elevated risk for MetS among Russian and Kurdish men. Interventions aiming at improving lifestyle-related factors are needed for reducing inequalities in the prevalence of MetS among migrant women. Effectiveness of interventions focusing on reducing overweight and obesity among Somali and Kurdish women should be evaluated.

The Prevalence of Potentially Traumatic Pre-Migration Experiences: A Population- Based Study of Russian, Somali and Kurdish Origin Migrants in Finland

Background: On-going mass conflicts and the resulting flow of displaced persons have increased interest in potentially traumatic experiences (PTEs) of migrants. However, studies on the topic using population-based samples are still scarce. Aims: The present study aims 1) to assess the prevalence of specific PTEs in Finlands migrant population and 2) to determine whether socio-demographic and migration-related factors are associated with PTEs. Methods: Data from the Finnish Migrant Health and Wellbeing Study (Maamu), a cross-sectional interview and health examination survey, was used. The sample comprised Russian; Somali and Kurdish migrants aged 18-64. PTEs, with eight specified traumatic event items common among those exposed to war and conflict, were measured using interview questions. Results: The prevalence of having at least one PTE was 21% among Russian, 58% among Somalian and 77% among Kurdish origin migrants, higher in Kurdish men than women and lower in Somali men than women. The most typical forms of PTEs among Kurds and Somalis were war and witnessing a violent death or injury. The most severe events (e.g. torture) were more common and the highest cumulative number of PTEs was among Kurds. Migrating as a refugee or asylum seeker was not associated with higher prevalence of PTEs. Conclusions: Results indicated an alarmingly high overall PTE prevalence among Kurdish and Somali migrants in Finland, especially among Kurds. Results suggest that effort to identify PTEs and interventions should be targeted not only at those migrating with a refugee of asylum seeker status but all migrants from conflict areas.
