The International Collaboration on Air Pollution and Pregnancy Outcomes (ICAPPO) was formed to better understand relationships between air pollution and adverse birth outcomes through standardized parallel analyses in datasets from different countries. A planning group with 10 members from 6 countries was formed to coordinate the project. Collaboration participants have datasets with air pollution values and birth outcomes. Eighteen research groups with data for approximately 20 locations in Asia, Australia, Europe, North America, and South America are participating, with most participating in an initial pilot study. Datasets generally cover the 1990s. Number of births is generally in the hundreds of thousands, but ranges from around 1,000 to about one million. Almost all participants have some measure of particulate matter, and most have ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. Strong enthusiasm for participating and a geographically-diverse range of participants should lead to understanding uncertainties about the role of air pollution in perinatal outcomes and provide decision-makers with better tools to account for pregnancy outcomes in air pollution policies.<\/jats:p>","DOI":"10.3390\/ijerph7062638","type":"journal-article","created":{"date-parts":[[2010,6,17]],"date-time":"2010-06-17T11:12:43Z","timestamp":1276773163000},"page":"2638-2652","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["International Collaboration on Air Pollution and Pregnancy Outcomes (ICAPPO)"],"prefix":"10.3390","volume":"7","author":[{"given":"Tracey J.","family":"Woodruff","sequence":"first","affiliation":[{"name":"UCSF, Program on Reproductive Health and Environment, Oakland, CA 94612, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer D.","family":"Parker","sequence":"additional","affiliation":[{"name":"National Center for Health Statistics\/CDC, Hyattsville, MD 20782, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kate","family":"Adams","sequence":"additional","affiliation":[{"name":"Health Effects Institute, Boston, MA 02110, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle L.","family":"Bell","sequence":"additional","affiliation":[{"name":"Yale University, New Haven, CT 06511, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulrike","family":"Gehring","sequence":"additional","affiliation":[{"name":"IRAS, Utrecht University, Utrecht, 3508 TD, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Svetlana","family":"Glinianaia","sequence":"additional","affiliation":[{"name":"Newcastle University, Newcastle, NE2 4AX, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eun-Hee","family":"Ha","sequence":"additional","affiliation":[{"name":"Ewha Womans University, Seoul 158-710, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Jalaludin","sequence":"additional","affiliation":[{"name":"University of New South Wales, Sydney 2052, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u00e9my","family":"Slama","sequence":"additional","affiliation":[{"name":"Inserm, Institut National de la Sant\u00e9 et de la Recherche M\u00e9dicale, U823 Institut Albert Bonniot, Avenir Team \u201cEnvironmental Epidemiology Applied to Fecundity and Reproduction\u201d, Grenoble, La Tronche, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2010,6,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"36","DOI":"10.1097\/01.ede.0000101023.41844.ac","article-title":"Particulate Air Pollution and Fetal Health: a Systematic Review of the Epidemiologic Evidence","volume":"15","author":"Glinianaia","year":"2004","journal-title":"Epidemiology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1365","DOI":"10.1289\/ehp.6857","article-title":"Does Particulate Air Pollution Contribute to Infant Death?
