↵3-150 As the English and Scottish representative samples include only a small number of children from ethnic minorities only the inner city sample was divided into four ethnic groups.
↵3-151 The models were adjusted for child’s sex and age, number of children in the family, parental atopy and maternal home smoking. The variables sample and ethnic group are also adjusted for social class or the Townsend score as appropriate.
