Own migration experience is not a risk factor for incident cardiovascular disease – a cohort study

Background Studies have shown differences regarding prevalence and incidence of chronic diseases among first (own migration experience) compared to second (born in host country) generation migrants. The aim of this study was therefore to investigate the incidence of cardiovascular diseases (CVD) among persons of Turkish descent with and without migration experience living in Berlin, Germany. Methods In 2012-2013, Berliners with a Turkish migration background were recruited, examined, and contacted again 5 years later via postal mail. Incidence of diagnosed CVD (myocardial infarction, stroke, coronary heart disease, heart failure, cardiac arrhythmia, intermittent claudicatio or transient ischaemic attack) was assessed via self-report. Incidence of any CVD is presented as number and percentages. Associations between the incidence of any CVD and having an own migration experience were investigated with uni- and multivariable regression analyses. Results are presented as odds ratios with a 95%-confidence interval (OR, 95%-CI). Results Data of 234 persons of Turkish descent (62.8% women) with a mean age±standard deviation of 44±12.4 years were included in the analyses. Out of these, 79.9% were first generation migrants. First compared to second generation participants differed regarding CVD incidence (any CVD 16.6% vs. 4.3%, respectively; p = 0.03), socio-demographic, and lifestyle factors. After adjusting for these factors, multivariable analysis showed that only BMI (OR 1.12 per BMI point, 95%CI [1.02;1.24], and having a diagnosis of dyslipidemia (OR 4.0, 95%CI [1.45;12.05]), were independently associated with CVD incidence. Conclusions In a cohort study with Berliners of Turkish descent, CVD incidence was associated with increasing BMI and dyslipidemia, but not with own migration experience. Future migration-related public health research needs to focus on the prevention of harmful health behaviours to avoid the progression of overweight/obesity and dyslipidemia. Key messages CVD incidence is higher in persons with migration experience compared to those without. Migration experience is not associated with CVD incidence after adjusting for confounders (e.g. age, BMI).
