Data collection

School nurses and health visitors interviewed mothers at home; this was the final interview with the mothers. Teachers completed a postal questionnaire about the study member and administered the cognitive tests. Headteachers completed the postal questionnaire about the school and school doctors carried out the medical examination. Hospitals to which study member children had been admitted were asked to complete a postal questionnaire about health, length of admission, visiting arrangements, diagnosis, treatment and discharge.
