Furthermore, we include information via G2-children on the parent not part of ECRHS/RHINE study. Asthma status and place of upbringing were reported in questionnaires by G1 in 2010-2012 and by G2 in 2013-2016. Binary regressions with farm upbringing as outcome were performed to explore the associations between parental asthma and offspring farm upbringing among G0-G1 …
