The results are adjusted for maternal age, maternal and paternal educational level, family income, maternal and paternal period of leave from work after child’s birth, maternal breastfeeding status when child is 18 months, and animals in the family. p < 10−9 (overall test of mean differences between categories) for the effect of household size (3 and more) on all outcome variables
