Pervasive Developmental Problems in the Clinical Range were defined as scores above the 98th percentile of a Dutch norm population

1

Basic model adjusted for children's age at the time of assessment and gender.

2

Additionally adjusted for maternal age, maternal educational levels, maternal ethnic background, marital status, maternal history of smoking and maternal psychopathology in pregnancy.

3

Additionally adjusted for paternal age, paternal educational levels and household income.

4

Additionally adjusted for parity, time of blood sampling during pregnancy and maternal body mass index.

5

Additionally adjusted for children's gestational age, birthweight and breast feeding at 6 months.

6

The values for continuous CRP concentrations were divided by standard deviation in the sample.

Pervasive developmental problems were defined as the scores in the highest 2% of the Child Behavior Checklist pervasive developmental problems scale (n=119)
