  1. Results are from multiply imputed data; coefficients are mean differences (MD) or odds ratios (OR) adjusted for sex and cell type proportion in model 1 and additionally adjusted for parental social class, education, smoking, alcohol use, depression, body mass index, age and relationship status as well as housing tenure, financial difficulties and parity in model 2. APGAR scores are based on Appearance, Pulse, Grimace, Activity, and Respiration at birth
