Abstract:
Our objective was to explore the relationship between mother smoking during pregnancy and physiological anxiety of children with Attention deficit-hyperactivity disorder. Cognitive profile was evaluated by Wechsler Intelligence Scale for Children, physiological anxiety by Children's Manifest Anxiety Scale. Mother's smoking was evaluated by the Fagerström test for nicotine dependence. Ninety-seven children with Attention Deficit-Hyperactivity Disorder combined type, 70 inattentive, and 48 hyperactive-impulsive, and 130 controls were studied. We found a higher frequency of high smoking dependence in mothers of children with Attention Deficit-Hyperactivity Disorder-combined type, and Attention Deficit Hyperactivity Disorder-hyperactive type in the Fagerström test; and a significant correlation between physiological anxiety in children with Attention Deficit Hyperactivity Disorder-combined type, with high and moderate maternal smoking level during pregnancy. In conclusion, data suggests, with caution a brain alteration of infants, induced by nicotine exposure during pregnancy in children with Attention Deficit Hyperactivity Disorder-combined type, and Attention Deficit Hyperactivity Disorder-hyperactive type.
