Effects of maternal acetonuria and low pregnancy weight gain on children's psychomotor development.

Data were analyzed from a large prospective study to determine if children had an excess of psychomotor or IQ impairment when their mothers had eight acetonuria, weight loss, or low weight gain during pregnancy. The effects of these maternal factors on children's development were assessed by a variety of mental and motor tests from the newborn period to 7 years of age. No consistent impairments were found at any age.
