The Hoorn studies and the Diabetes Care System West-Friesland studies were designed to investigate the course of development and progression of diabetes over a period of several years. The aim is to investigate which factors (psychological, social, biological and genetic) play a role in the development and progression of diabetes.

The DCS cohort is an on-going population-based cohort including almost all people with type 2 diabetes (T2D) in the catchment area of the DCS, a primary care setting in the West-Friesland area of the Netherlands. As part of routine diabetes care, participants receive a standardized annual assessment with measurement of diabetes-related risk factors and complications.

The resulting database included 13,955 people with T2D in 2017, with follow-up ranging from 1 to 19 years. The study has been approved by the Medical Ethical Review Committee of the VU University Medical Center, Amsterdam. Individuals were informed about the use of their data and were offered an opt-out. Data were used anonymously. A description of the DCS cohort has been published previously.
