Combined association of BTEX and material hardship on ADHD-suggestive behaviours among a nationally representative sample of US children.

ABSTRACT:

Background

Previous research shows that environmental and social factors contribute to the development of attention-deficit/hyperactivity disorder (ADHD).

Objective

To determine the relationship between early-life exposure to common ambient air pollutants (benzene, toluene, ethylbenzene, and xylene, also known as BTEX), household material hardship (a measure of socio-economic status), and ADHD-suggestive behaviours in kindergarten-age children.

Methods

Pollutant exposure estimated from the 2002 National Air Toxics Assessment at each child's residential ZIP code at enrolment was linked to the Early Childhood Longitudinal Study Birth Cohort (n = 4650). Material hardship was assigned as a composite score of access to food, health care, and housing. Kindergarten teachers
