Disparities in treatment of diabetes and hypertension among groups of foreign origin and the general Finnish population

Background: Migrants from low-income countries are more predisposed to diabetes and cardiovascular risks than host European natives, but how treatment targets are met in migrant patients is unclear. We examined health service use and treatment of diabetes and hypertension among selected migrant groups and the general Finnish population and compared prevalence of cardiovascular risk factors between patients and non-patients. Methods: Cross-sectional data from randomly sampled 30- to 64-year-old participants (387 Russian, 198 Somali and 343 Kurdish origin migrants) of the Migrant Health and Wellbeing Survey (2010-2012) were used. Health 2011 survey data (n = 1086) were used as a comparison group. Results: Compared with the general population, diabetes-related doctor/nurse visits were more frequent among Russian and Somali, but not the Kurdish group. Use of prescribed antidiabetic and antihypertensive drugs were significantly lower among Russians (78%/56%) and Kurdish (68%/58%), but not in Somalis (85%/62%) compared with the general population (96%/78%). Obesity, elevated blood pressure and elevated glucose levels were more prevalent in patients than non-patients, and over 60% of patients and over 70% of non-patients had elevated plasma low density lipoprotein cholesterol. Differences in cardiovascular disease (CVD) risk profiles between patients and non-patients were not associated with socio-economic factors. Conclusions: This study indicates disparities in prevalence and management of diabetes and hypertension and their associated risk factors among ethnic groups. Diabetes, CVD risks and treatment outcomes in patients were sub-optimal, especially among foreign origin groups. Comprehensive health promotion strategies are needed to improve cardiometabolic health in vulnerable populations.
