Country of birth-specific and gender differences in prevalence of diabetes in Sweden

• Objective: The aim was to investigate country or region of birth-specific prevalence and gender differences of diabetes in residents in Sweden, using Swedish-born men and women as referent. Methods: The Apolipoprotein MOrtality RISk (AMORIS) cohort was used (184,000 men and 151,453 women) aged between 20 and 80 years, with data from the CALAB laboratory, Stockholm, 1985-1996. Diabetes was defined as fasting glucose >= 7.0 mmol/L or a hospital diagnosis of diabetes. Country of birth was obtained by linkage to Swedish Censuses 1970-1990. Standardized prevalence rate ratios (SPRR) with 95% confidence intervals (95% CI) were estimated. Results: Five groups of women and one group of men had a significantly higher prevalence than Swedish-born (based on SPRR): women born in Iraq (6.0 (95% CI 1.3-28.9)), North Africa (6.9 (95% CI 3.1-15.3)), South Asia (3.1 (95% CI 1.0-10.0)), Syria (5.3 (95% CI 1.8-16.0)), Turkey (3.7 (95% CI 1.2-10.9)) and men born in other Middle Eastern countries (2.3 (95% CI 1.0-5.5)). Swedish-born men had a higher age-standardized prevalence of diabetes (3.9%) than Swedish born women ( 2.5%). A higher prevalence among men was also seen in other Western countries. In contrast, a higher age-standardized prevalence among women was observed in immigrants from Turkey (8.9% vs. 3.1%, p < 0.001), Syria (13.1% vs. 4.0%, p = 0.002), and North Africa (16.8% vs. 6.6%, p < 0.001). Conclusion: Female immigrants to Sweden from Iraq, North Africa, South Asia, Syria, and Turkey have an increased prevalence of diabetes of substantial public health concern.
