ROAD TRAFFIC, NO2 EXPOSURE AND RESPIRATORY FUNCTION AMONG CHILDREN (VESTA STUDY)

Within the multicenter VESTA case-control study on childhood asthma and traffic air pollution, this research studied the association between respiratory function (RF) and NO2 personal exposures or intensity of traffic close to homes and schools. The relative contribution of various indoor/outdoor emission sources on personal NO2 exposures was also assessed. The RF was measured with a One-Flow tester. NO2 personal exposure was measured using passive Ogawa samplers worn for 48 hours by study participants, aged 4-14 years old. Exposure to traffic exhausts was assessed through an index based on a time-weighted average of traffic density to road distance norms. The most influential variables that predicted NO2 personal exposures were the traffic index, use of a gas cooker at home, and background ambient air pollution, with variable associations across cities. No association was found between RF and levels of NO2 personal exposure; FEV1 or PEFR values, however, were associated with the traffic index, in 2 of 4 cities. These results suggest that cumulative exposure to traffic exhausts may alter the RF of children.
