Abstract

Objective To investigate the relationship between secondhand tobacco smoke (SHS) exposure and neuromotor function in children. Study design We studied 404 children aged 7-9 years who were exposed to SHS and other environmental neurotoxicants. Parents reported smoking habits, and serum cotinine levels were measured in children to determine SHS exposure. The Halstead-Reitan Finger Oscillation Test, Purdue Grooved Pegboard Test-Kiddie version, and Bruininks-Oseretsky Test of Motor Proficiency 2-Short Form were used to assess neuromotor function. Multivariable regression models that accounted for potential confounders were used to evaluate the associations. Results Approximately 50% of the children were exposed to SHS based on serum cotinine measures. Exposure to SHS was significantly associated with motor impairment in children, including diminished visuomotor coordination (P =.01), fine motor integration (P =.01), balance (P =.02), and strength (P =.04) after adjusting for exposures to lead and manganese, age, sex, body mass index, measures of parental cognitive abilities, parental education, and quality of home environment. Conclusion SHS is a neurotoxicant that may be associated with impaired childhood neuromotor function.
