In this project, approximately 120 body measurements (body length, circumference and volume) are automatically determined using a laser-based 3D body scanner. This highly standardised measurement takes approximately 10 seconds and is carried out on participants in the German National Cohort (NAKO) at the study centre in Halle and other NAKO locations. In addition, participants are asked to assess their actual and desired body shape using pictograms. The data collected can be used for subsequent investigations of the association of the parameters collected with other phenotypes in cross-sectional analyses and with the incidence of chronic diseases in longitudinal analyses.
