The association between socio‐economic status and diabetes care and outcome in children with diabetes type 1 in Germany: The DIAS study (diabetes and social disparities)

摘要

Abstract Objective To evaluate the association between socioeconomic status (SES) and diabetes outcomes in German children and adolescents. Methods A total of 1829 subjects 18 years old with type 1 diabetes mellitus from 13 German diabetes centers were included from June 2013 until June 2014. Data were collected within the multicenter DPV (Diabetes Prospective Follow‐up) registry. SES was measured with a composite index. Multivariable regression models were applied to analyze the association of SES and outcomes adjusted for age, sex, diabetes duration, and migration status. Results Low SES was significantly associated with worse diabetes outcomes: higher hemoglobin A1C (HbA1c) (64.3 mmol/mol), lower proportion of insulin pump therapy (43.6%), fewer daily self‐monitored blood glucose (SMBG) measurements (5.7), more inpatient days per patient‐year (5.8) compared to patients with medium/high SES (HbA1c: 61.3 mmol/mol, P 0.001/59.8 mmol/mol, P 0.0001; proportion of pump therapy: 54.5%, P 0.01/ 54.9%, P 0.01; SMBG: 6.0, P 0.01/ 6.1, P 0.01; inpatient days: 4.5, P 0.0001/3.4, P 0.0001). The inclusion of migration status in the models resulted in only minor changes in the outcomes. Conclusion Despite free health care, low SES is associated with unfavorable diabetes outcomes in Germany. The poorer diabetes outcomes of children with diabetes have been attributed to their migration status and may be partly explained by low SES. Both factors must become part of targeted diabetes care in children and adolescents with type 1 diabetes.
