The study encompasses human biomonitoring HBM (spot urine and venous blood), health exams (e.g. blood pressure, anthropometry, accelerometry, lung function) and accompanying questionnaires on health status, exposure, attitude regarding health research, coronavirus and the WHO-quality of life questionnaire. Questionnaires were mostly answered online; HBM-samples were drawn in a study center, where also the health exams took place.\n\t\t\nData\/samples are available for four different types of populations:\n    R - Random sample of participants from the general population of the Cantons of Vaud and Bern\n    C - Convenience sample of vegans\/vegetarians from a sub-study on selenium, in the Canton of Vaud\n    S - Self-selected participants from all over Switzerland\n    W - Wave 0 participants from a random sample of the general population of the Cantons of Vaud and Bern that was used before the pandemic. \n\nReasoning for the separation of R and W: After the pandemic, due to the long break, a new random sample had to be drawn and a new questionnaire relating to the SARS-CoV-2 pandemic was included, that was not answered by Wave 0 participants that had already completed the study visit (31 participants). Some participants from Wave 0, however, came to the study visit when the study resumed and completed the SARS-Cov-2 questionnaire.\n\nThe following data categories are available: \n    1.\tAccompanying data \n    2.\tSelf-administered questionnaires data\n    3.\tHealth examination data\n    4.\tAnalytical data associated with collected HBM samples (blood, urine)\n\nThey are subdivided into three main categories that are available as separate data packages:\n    1.\tComplete participation: Data\/samples from participants who completed all steps of the study, including the study visit (data available: self-administered and interview questionnaire data, health exams and HBM-samples).\n    2.\tPartial participation: Data\/samples from participants who completed the questionnaires but did not take part in the study visit (data available: self-administered questionnaire data)\n    3.\tNon-respondents: data from invited participants who refused to participate in the study but accepted to answer some general questions by phone instead.\n\nMost self-selected participants \u201cS\u201d only replied to the self-administered questionnaires, but 9 self-selected participants participated in the study visit.","coll_dates":[{"start":"2020-02-01","end":"2021-12-15","cycle":""}],"nation":[{"name":"Switzerland","abbreviation":"CHE"}],"geog_coverage":"Random sample, cantons of Vaud and Berne \/ Selenium sub-study convenience sample, canton of Vaud \/ Self-selected participation, Switzerland","analysis_unit":"Individuals.\n\t\t  \n\t\t  Complete participation :\n-\tRandom sample : N= 638\n-\tSelenium sub-study convenience sample : N= 109*\n-\tSelf-selected participants : N= 9\n-\tWave 0 : N= 48\n-\tTOTAL : N = 789*\n\n*15 participants are both R and C.

Due to the long break, a new random sample had to be drawn for invitation waves 1-5 that form the sample R.\n\n\n*Participants from the random sample following a vegetarian\/vegan diet were flagged and invited to participate in the selenium sub-study.
