['Infants from anthroposophic families have low cortisol levels and low risk of IgE-sensitization during first 2\xa0years of life. Our aim was to study the impact of an anthroposophic lifestyle and cortisol levels at 6\xa0months on allergy sensitization up to age 5\xa0years.', 'A total of 507 families participated from maternal healthcare centers. Parental lifestyle was categorized as anthroposophic, partly anthroposophic, or non-anthroposophic. Blood samples for analyzes of sensitization were obtained from parents at inclusion and from children at 6, 12, 24, and 60\xa0months. Salivary samples were collected at home at 6\xa0months.', 'Sensitization increased from 2.9% to 26.0% in the anthroposophic group, from 8.4% to 26.8% in the partly anthroposophic group, and from 19.1% to 44.1% in the non-anthroposophic group. Children from anthroposophic families had lower cortisol levels in the morning, afternoon, and evening. The odds ratio (OR) for anthroposophic lifestyle was always <1 and lowest at 12\xa0months (OR, 0.10; 95% CI, 0.03-0.36). Adjusting for cortisol levels at 6 months increased these ORs at 12 and 24\xa0months. At the same ages, ORs for sensitization were elevated also for cortisol levels at 6\xa0months. Analyzes in children not sensitized at 6\xa0months confirmed the cortisol-related risk of sensitization.'] Are anthroposophic lifestyle and salivary cortisol associated with a lower risk of sensitization during childhood?
