Model B = adjusted for gender, maternal social class and maternal education;

Fully adjusted Model C = adjusted for gender, maternal social class, maternal education, maternal anxiety and maternal depression

RAP = Recurrent Abdominal Pain defined as 5+ episodes of stomach pain in the last 12 months
