    Sammanfattning : Background and Aims: While the development of type 1 diabetes (T1D) in childhood is in part genetically conditioned, non-genetic/environmental factors seem to play a decisive role in its aetiology. The incidence of T1D has been increasing rapidly during the last years, and its prevalence is higher in countries of high economical welfare like Sweden. LÄS MER

    Sammanfattning : Allergic disorders are caused by a combination of hereditary and environmental factors. The hygiene hypothesis postulates that early-life microbial exposures impede the development of subsequent allergic diseases. However, unambiguous evidence that microbes reduce the development of allergic disorders is still lacking. LÄS MER
