Population:
The Swedish portion of the study population was recruited in Uppsala and Järna (Sweden) and consists of four distinct lifestyle groups: 1. A farm group of children living on farms (N = 37). 2. A farm reference group, consisting of children living in the farmers’ area, but not growing up on farms (N = 11). 3. A group of anthroposophs (N = 19; recruited at Steiner schools and called ‘Steiner’ throughout the text). 4. A Steiner reference group, consisting of children living in the same area but not following the anthroposophic lifestyle (N = 7).

- Observational study
- Cross-sectional study
Description of study design:
The study population consisted of children aged 5-13 years living in the Uppsala and Järna regions (Sweden) and entailed participants living on farms, children with anthroposophic lifestyles and two reference groups of children living in the same areas but not following these lifestyles. For this study, all 74 fecal samples of the Swedish part of the PARSIFAL study were obtained. Samples were taken by the parents, first stored at –20 °C, and finally stored at –80 °C before DNA extraction, as described by Dicksved et al. (https://doi.org/10.1128/AEM.02223-06). The participant data and samples that were used for the analyses in this study were collected between October 2000 and May 2002. A questionnaire was completed by the parents and has previously been reported in detail by Alfvén et al. (https://doi.org/10.1111/j.1398-9995.2005.00939.x).
