The prevalence of atopic eczema was defined using a questionnaire based on the UK diagnostic criteria²⁶ (12 month period prevalence) plus skin examination by a dermatologist (point prevalence). Eczema severity was assessed using the Three Item Severity score.²⁷ The lifetime prevalence of asthma and seasonal rhinitis were defined by parental questionnaire. The denominator varies in order to maximise the use of available data.
