The Austrian LEAD Study

The Austrian LEAD Study is a longitudinal, observational, epidemiological cohort study aiming to investigate respiratory health through life. The survey includes a representative sample of the Austrian general population between 6 and 80 years of age and focuses on three areas:

  1. Normal and pathologic lung growth and development (natural course of lung function)
  2. Genetic, environmental and socioeconomic risk factors for abnormal lung function
  3. Extrapulmonary manifestations of abnormal lung function and related comorbidities (cardiovascular disease, metabolic disorders, depression and anxiety)

The examination program of the Austrian LEAD Study includes a comprehensive diagnosis of lung function and cardiac status. In addition, body composition (DXA scan), socio-demographic status, psychosocial factors and pollution levels at home and at work are recorded. The examination protocol includes blood and urine samples, which are stored in the biobank of the Medical University of Vienna for later planned analyses. In total, each data set contains more than 1.500 individual parameters. In addition to the extensive urban cohort from the city of Vienna, the sample also includes a smaller rural comparison sample from the surrounding area. A detailed summary of the objectives and methods is included in the publication:

Current status

The Austrian LEAD Study started in 2012. Between 2012 and 2016 11.426 participants were recruited and completed the first cross-sectional examination. Phase 2 with the first longitudinal examination (4-years follow-up) started in 2017. Until now more than 6000 participants have been re-examined and the second phase is expected to be finished in February 2021. Phase 3 (8-years follow-up) with the second re-examination will be carried out between 2021 and 2024.
