Swedish schoolchildren showed a high incidence of perceived food hypersensitivity, particularly to cow’s milk, according to recent study results.
Researchers studied a population-based cohort of 2,585 children (aged 7 to 8 years) from three Swedish towns who participated in a parental questionnaire in 2006. Ninety percent of children from two of the towns (n=1,700) also participated in skin prick testing (SPT) with airborne allergens. In 2010, when the children were aged 11 to 12 years, the same methods were used, with 89% participation. At follow-up, 652 children in the SPT cohort provided a blood sample for analysis of IgE-antibodies.
