Increased traffic exposure and negative birth outcomes : a prospective cohort in Australia
Barnett, Adrian G., Plonka, Kathryn, Seow, W. Kim, Wilson, Lee-Ann M., & Hansen, Craig A. (2011) Increased traffic exposure and negative birth outcomes : a prospective cohort in Australia. Environmental Health, 10(1), p. 26.
Background: Pregnant women exposed to traffic pollution have an increased risk of negative birth outcomes. We
aimed to investigate the size of this risk using a prospective cohort of 970 mothers and newborns in Logan,
Queensland. ----- -----
Methods: We examined two measures of traffic: distance to nearest road and number of roads around the home.
To examine the effect of distance we used the number of roads around the home in radii from 50 to 500 metres.
We examined three road types: freeways, highways and main roads.----- -----
Results: There were no associations with distance to road. A greater number of freeways and main roads around
the home were associated with a shorter gestation time. There were no negative impacts on birth weight, birth
length or head circumference after adjusting for gestation. The negative effects on gestation were largely due to
main roads within 400 metres of the home. For every 10 extra main roads within 400 metres of the home,
gestation time was reduced by 1.1% (95% CI: -1.7, -0.5; p-value = 0.001).----- -----
Conclusions: Our results add weight to the association between exposure to traffic and reduced gestation time.
This effect may be due to the chemical toxins in traffic pollutants, or because of disturbed sleep due to traffic
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
