  Country background, education level, employment and disability in young-onset type 2 diabetes Background and Aims Young-onset type 2 diabetes (YOD – diagnosis before age 40) entails high disease burden and is mainly managed in general practice. Knowledge of how socioeconomic status and country background impact YOD risk is sparce. We aimed to study effects of education level and country background on YOD risk and effects of YOD on employment and disability. Materials and Methods Cross-sectional data on 10241 individuals with type 2 diabetes (T2D) from Norwegian general practices (ROSA 4 study, 2014), linked to data on country background, education level, disability benefits and employment, were compared with population data matched for age, sex and residential area. Using negative binomial regression and adjusting for age and sex, we analyzed YOD risk by country background and education level, and the effects of YOD on risk of disability and labour market absence. Results T2D risk was increased in non-Western compared to Norwegian background. South Asians exhibited the greatest risk increase, five-fold for T2D (adjusted incidence rate ratio, aIRR 4.7 (4.3-5.2)) and nine-fold for YOD (aIRR 8.9 (7.3-11.0)). T2D risk in low education was almost double that in high education, with YOD risk significantly higher than for later onset T2D (see table). There was significant interaction between low education and country background, with only Westerners exhibiting a substantially increased risk of YOD (aIRR 3.2 (2.4-4.4)). Disability risk was doubled in T2D (aIRR 2.2 (2.0-2.3) and three-fold higher in YOD (aIRR 3.1 (2.7-3.5) than in the population. Workforce participation was only reduced in T2D diagnosed before age 50. Conclusion Non-Western, particularly South Asian background and low education was associated with increased risk of YOD. Low education was an important YOD risk factor only for Westerners. Risk of disability and labour market absence was significantly higher in YOD than in later onset T2D and in the general population.

  EDUCATION LEVEL AND COUNTRY BACKGROUND IN YOUNG-ONSET TYPE 2 DIABETES Background Type 2 diabetes (T2D) is associated with socioeconomic status and country background, but knowledge about the influence of these factors in young-onset T2D (YOD) is sparce. We aimed to examine the risk of YOD according to education level and country background. Methods Cross-sectional data from 2014 on 10241 individuals with T2D from Norwegian general practices (ROSA 4 study) were linked to data from Statistics Norway on country background and education level. Using separate data for the population of Norway, ROSA 4 individuals were compared with individuals matched for age, sex and residential area. Poisson regression analyses of T2D risk by country background and education compared YOD (diagnosis before age 40) with later onset T2D. Results In ROSA 4, 10% had YOD. Of these, 39% had non-Western background (22% South Asians) vs. 20% in the matched population. Among South Asians 29% of T2D was diagnosed before age 40 vs 7% of those with Norwegian background. Compulsory education was the highest education level in 36% in ROSA 4 vs 26% in the matched population. In YOD, these shares were 41% and 21%. T2D risk was increased in non-Western background compared to Norwegian background, particularly in South Asians (Incidence rate ratio, IRR 4.2 (4.0-4.5)). The risk was doubled in YOD (IRR 8.9 (8.0-9.8)). T2D risk was increased in individuals with lower education levels and the effect was larger in YOD (see table). There was an interaction between education level and country background in their association with YOD risk, individuals with Norwegian background, but not to South Asians, with low education having increased risk. Conclusion Non-Western background is associated with increased risk of T2D onset at a younger age. South Asians have particularly high risk. Low education is a risk factor for young-onset T2D in Norwegians, but not in South Asian immigrants.
