Donor InSight
In the Netherlands the blood supply is dependent on voluntary non-remunerated donors. Sanquin, by law the only blood bank in the Netherlands, has a very loyal donor population of about 2.5% of the Dutch population that make approximately 800.000 donations per year. Donor InSight (DIS) is a cohort study among this donor population.
Three questionnaire rounds, DIS-I in 2007-2009 (n=31,338), DIS-II in 2012-2013 (n=34,823, of whom 22,132 also participated in DIS-I), and DIS-III in 2015-2016 (n=3,046) were completed to gain more insight into donor health and motivation. The questionnaires cover demographics, lifestyle behaviours, family composition, motivations and barriers for donation, health status and disease. Data from the donor database, including donation details and donor screening results (e.g. blood pressure and haemoglobin measurements) are linked to DIS data.
DIS-III also includes GWAS, complete blood counts, lipid profiles, measurements of markers of iron metabolism, accelerometer measurements in a subset, and additional questions on iron-deficiency related symptoms.
Donor InSight was set up by Sanquin Research, Donor Studies and Sanquin Blood Bank with financial support of the Sanquin Blood Supply Foundation.
