Abstract
In industrialized countries atopic diseases have been reported to be less likely in children and adolescents with a migrant background compared to non-migrants. This paper aimed at both examining and comparing prevalence of asthma, allergic rhinoconjunctivitis and atopic dermatitis and allergic sensitization to specific IgE antibodies in children and adolescents with and without a migrant background. Using data of the population-based German Health Interview and Examination Survey for children and adolescents (KiGGS; n = 17,450; 0–17 years), lifetime and 12-month prevalence of atopic diseases and point prevalence of 20 common allergic sensitizations were investigated among migrants compared to non-migrants. Multiple regression models were used to estimate the association of atopic disease and allergic sensitization with migrant background. In multivariate analyses with substantial adjustment we found atopic dermatitis about one-third less often (OR 0.73, 0.57–0.93) in participants with a two-sided migrant background. Statistically significant associations between allergic sensitizations and a two-sided migrant background remained for birch (OR 0.73, 0.58–0.90), soybean (OR 0.72, 0.54–0.96), peanut (OR 0.69, 0.53–0.90), rice (OR 0.64, 0.48–0.87), potato (OR 0.64, 0.48–0.85), and horse dander (OR 0.58, 0.40–0.85). Environmental factors and living conditions might be responsible for the observed differences.
Highlights
It is well known that the prevalence of atopic diseases, such as asthma, allergic rhinoconjunctivitis and atopic dermatitis has increased substantially over the last decades, in affluentWestern societies and, have become an important health problem, especially among children and adolescents [1,2,3,4,5,6,7,8].In industrialized countries atopic diseases have been reported to be less likely in children and adolescents with a migrant background compared to non-migrants
The results show that children and adolescents with a two-sided migrant background had about one-third less often the chance of having atopic dermatitis
The results show that children and adolescents with a of two-sided allergens tested, except for house dust mites (Dermatophagoides pteronyssinus and Dermatophagoides migrant background were statistically significant less often sensitized to almost all of the allergens farinae), mold (Cladosporium herbarum and Aspergillus fumigatus) and egg white than non-migrants

In industrialized countries atopic diseases have been reported to be less likely in children and adolescents with a migrant background compared to non-migrants. An international comparative study conducted by the WHO among school-aged children (11, 13 and 15 years) showed that children with a two-sided migrant background were less often affected by at least one allergy (27.4%) compared to non-migrants (38.9%) [9].
