2. STUDY OBJECTIVE
To examine the association of socioeconomic status (SES) with cardiovascular disease (CVD) and death in a large cohort of patients with type 1 diabetes
Rawshani A. et al. Diabetes Care 2015;38:

3. STUDY DESIGN AND METHODS
Clinical data from the Swedish National Diabetes Register were linked to national registers to obtain information on the following:
Income
Education
Marital status
Country of birth
Comorbidities
Events
Patients were followed until a first incident event, death, or end of follow-up
Association between socioeconomic variables and the outcomes was modeled using Cox regression

4. RESULTS
Patients included 24,947 individuals with mean (SD) age and follow-up of 39.1 (13.9) and 6.0 (1.0) years
Death and fatal/nonfatal CVD occurred in 926 and 1,378 individuals
Compared with being single, being married was associated with 50% lower risk of death, cardiovascular (CV) death, and diabetes-related death
Rawshani A. et al. Diabetes Care 2015;38:

5. RESULTS
When compared with individuals in the highest income quintile, those in the two lowest quintiles had:
Twice as great a risk of fatal/nonfatal CVD, coronary heart disease, and stroke
Roughly three times as great a risk of death, diabetes-related death, and CV death
Individuals with a college/university degree had 33% lower risk of fatal/nonfatal stroke
Immigrants had 19%, 33%, and 45% lower risk of fatal/nonfatal CVD, all-cause death, and diabetes-related death, respectively, compared with Swedes
Men had 44%, 63%, and 29% greater risk of all-cause death, CV death, and diabetes-related death

9. Figure 1—Adjusted HRs for CV events among patients with type 1 diabetes. Two models were computed for each outcome. The minimally adjusted
models were identical for each outcome and controlled for age, sex, immigrant status, and duration of diabetes. Fatal/nonfatal CVD was additionally
adjusted for smoking, systolic blood pressure, HbA1c, exercise level, eGFR, albuminuria, total cholesterol–to–HDL ratio, antihypertensive medications,
statins, and aspirin. Fatal/nonfatal CHD and fatal/nonfatal stroke were adjusted for the same covariates. Note that the category “married”
includes individuals who were cohabiting (registered as partners). educ., education.

11. Figure 2—Adjusted HRs for death from any cause and death from specific causes among patients with type 1 diabetes. Two models were computed
for each outcome. The minimally adjusted models were identical for each outcome and controlled for age, sex, immigrant status, and duration of
diabetes. All-cause death and CV death were additionally adjusted for smoking, HbA1c, exercise level, eGFR, CVD, albuminuria, and HF. Diabetesrelated
death was additionally adjusted for smoking status, systolic blood pressure, HbA1c, exercise level, eGFR, chronic kidney disease, and
albuminuria. Note that the category “married” includes individuals who were cohabiting (registered as partners). educ., education.
