Purpose
There is limited research on individuals undergoing self-initiated health examinations, and the Werlabs cohort will be a base for such research.
Participants
All individuals aged 18 or older who had undertaken a self-initiated health examination at Werlabs AB with at least one recorded value of creatinine or cholesterol in Sweden (from 1 January 2015 through 31 December 2023) was included. Medical history and anthropometric measurements were self-reported through an online questionnaire. We describe cohort baseline characteristics, demographic variables and cardiometabolic risk factors.

The study population includes 149 556 individuals who provided at least one health screening. The median (IQR) age was 43 (33–54) years and 54% were women. The most common self-reported chronic disease was hypertension (4.5%), followed by cardiovascular disease (0.9%) and 12.6% reported values of obesity. The prevalence was 2.1% for diabetes, 1.2% for kidney disease (including an estimated glomerular filtration rate of 3.0 mmol/L and 4.1% for anaemia (haemoglobin
