Abstract
We studied children aged 7.5 years participating in the Avon Longitudinal Study of Parents and Children (ALSPAC), a population based birth cohort study established in 1990.3 Two stage screening included a sensitive initial radioimmunoassay for antibodies to tissue transglutaminase (endomysial antigen) with further testing of positive samples for IgA-EMA by indirect immunofluorescence.4 Children with tTG antibodies below the 97.5th centile were defined as antibody negative. Height, weight, and haemoglobin levels were measured at dedicated study clinics. Details of gastrointestinal symptoms and special diets were collected by routine questionnaire at age 6.75 years.Keywords
