Affecting approximately 5-6% of the primary school population, developmental coordination disorder (DCD) is a condition characterized by poor motor proficiency that interferes with a child’s activities of daily living. The cause of DCD is not yet understood; however, it is known that children with DCD are more likely to have other co-occurring developmental disorders such as attention-deficit hyperactivity disorder (ADHD). While there is a growing body of evidence linking ADHD to smoke exposure in utero, there is limited research investigating a similar link between smoke exposure in utero and DCD. The purpose of this study was to examine the effect of SHS exposure in utero in children with DCD and a group of typically developing (TD) children.
Methods – A case-control study was conducted to compare children with DCD to TD children on their exposure to SHS in utero and other demographic variables. At baseline, participants included 63 DCD children and 63 healthy controls. All children were assessed for motor proficiency, intelligence, and ADHD. Mother’s SHS exposure during pregnancy and other demographic variables were obtained from a parent completed survey.
Results – Multinomial logistic regression analyses revealed that children exposed to SHS in utero were significantly more likely to be at high risk for DCD than children who were not exposed to SHS in utero, even after adjusting for associated demographic variables. Furthermore, children exposed to SHS in utero were significantly more likely to be at moderate-high risk for DCD, whether or not ADHD was co-occurring.
Conclusion – Results from this study suggest that exposure to SHS during pregnancy has negative effects on fetal development and appears to be a contributor for DCD. Further study is needed to examine the specific mechanisms linking SHS exposure in utero to motor coordination problems in children. / Thesis / Master of Science (MSc)
