Exploring Gender Differences in Relationships of Prenatal Traffic Air Pollution Exposures with Attention and Memory Measures in Early School-aged Urban Children

Abstract:

Background: Prenatal air pollution may impact children’s neurodevelopment albeit research is limited. Studies on gender-specific effects are more sparse. Aims: To examine effects of prenatal exposure to traffic-related black carbon (BC) and fine particulate matter with diameter?2.5?m (PM2.5) on children's attention and memory measures obtained at age 6.4±0.9 years in a Boston pregnancy cohort (n=150 assessed to date). Methods: BC and PM2.5 estimates were derived using validated spatial-temporal land-use regression models based on mother's residence during pregnancy. Select attention (omission error, commission error, and hit reaction time [HRT] t-scores from the Conners' Continuous Performance Test-II) and memory (general, verbal, and visual memory scores from the Wide Range Assessment of Memory & Learning-2) domains were assessed. Overall associations were examined in multiple linear …
