A Swedish study of children admitted to hospital within the first year of life for lung infection has found that the increased risk this poses for later development of asthma is exacerbated by low gestational age.
UK research indicates that children with asthma and eczema are significantly more likely to have psychotic experiences during adolescence, boosting a previously reported relationship between schizophrenia and atopic disorders.
Research from Finland shows that children born late preterm or early term are at significantly increased risk for asthma compared with those born at term, and these births account for the majority of excess asthma burden due to prematurity.
Data from the Netherlands indicate that living in close proximity to livestock farms is associated with decreased respiratory morbidity, including asthma, allergic rhinitis, and chronic obstructive pulmonary disease.
Any beneficial effects of the neonatal Bacillus Calmette–Guérin vaccine on childhood asthma symptoms and outcomes are likely to be transient, disappearing by adolescence, show follow-up findings from the Manchester Community Asthma Study.
