Comparative Study
Age, sex, geographical and socio-economic variations in admissions for anaphylaxis: analysis of four years of English hospital data.
Although the most severe of the allergic disorders, the epidemiology of anaphylaxis remains poorly described. Hospital admissions for anaphylaxis in England more than doubled during the 1990s. ⋯ This study identifies striking national age, sex, geographical and socio-economic variations in the incidence of inpatient admissions for anaphylaxis in England, affording important opportunities to generate and test aetiological hypotheses. Risk of anaphylaxis admission is considerably increased in females of child-bearing age and those residing in southern, rural, and affluent areas are independent risk factors for anaphylaxis admission.
