The effect of maternal nutritional supplementation during pregnancy and lactation on the mental and motor development of infants was studied in a rural population in Taiwan. Women were randomly assigned to 2 treatment groups: 1 received a high-calorie and protein supplement ("supplement" group); the other received a placebo ("control" group). Infants received no direct supplementation. At approximately 8 months of age, the mental and motor development of the infants was assessed using a research to maternal supplementation in either scale, nor were the mental scale scores of infants of supplement mothers significantly higher than infants of control mothers. However, the motor scores of supplement infants were higher than those of control infants, which is consistent with the findings of 2 other large-scale nutritional supplementation studies.

Women were randomly assigned to 2 treatment groups; 1 received a high calorie and protein supplement (supplement group) and the other received a placebo (control group). Infants received no direct supplementation. At approximately 8 months of age, the mental and motor development of the infants was assessed using a research version of the Bayley Scales of Infant Development. There were no sex differences in response to maternal supplementation in either scale, nor were the mental scale scores of infants of supplement mothers significantly higher than infants of controls. However, the motor scores of supplement infants were higher than those of control infants, which is consistent with the findings of 2 other largescale nutritional supplementation studies.
