The purpose of this study was to examine the relationship between PD and pesticide levels in groundwater. This cross-sectional study included 332 971 Medicare beneficiaries, including 4207 prevalent cases of PD from the 2007 Colorado Medicare Beneficiary Database. Residential pesticide levels were estimated from a spatial model based on 286 well water samples with atrazine, simazine, alachlor, and metolachlor measurements. A logistic regression model with known PD risk factors was used to assess the association between residential groundwater pesticide levels and prevalent PD. We found that for every 1.0 \u00b5g\/L of pesticide in groundwater, the risk of PD increases by 3% (odds ratio = 1.03; 95% confidence interval: 1.02-1.04) while adjusting for age, race\/ethnicity, and gender suggesting that higher age-standardized PD prevalence ratios are associated with increasing levels of pesticides in groundwater.<\/jats:p>","DOI":"10.1177\/1091581815583561","type":"journal-article","created":{"date-parts":[[2015,5,4]],"date-time":"2015-05-04T20:51:16Z","timestamp":1430772676000},"page":"266-273","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":46,"title":["Groundwater Pesticide Levels and the Association With Parkinson Disease"],"prefix":"10.1177","volume":"34","author":[{"given":"Katherine A.","family":"James","sequence":"first","affiliation":[{"name":"Department of Family Medicine, University of Colorado, Denver, CO, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deborah A.","family":"Hall","sequence":"additional","affiliation":[{"name":"Department of Neurological Sciences, Rush University, Chicago, IL, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,5,4]]},"reference":[{"key":"bibr1-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.48.6.1583"},{"key":"bibr2-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwp006"},{"key":"bibr3-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1080\/10599240801986215"},{"key":"bibr4-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2377-8-6"},{"key":"bibr5-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1016\/j.jns.2007.06.024"},{"key":"bibr6-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000304049.31377.f2"},{"issue":"94","key":"bibr7-1091581815583561","first-page":"364","volume":"165","author":"Kamel F","year":"2007","journal-title":"Am J Epidemiol"},{"key":"bibr8-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000000083"},{"key":"bibr9-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1016\/j.toxlet.2009.03.026"},{"key":"bibr10-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1016\/j.tox.2006.12.007"},{"key":"bibr11-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1001\/archneurol.2010.101"},{"key":"bibr12-1091581815583561","doi-asserted-by":"publisher","DOI":"10.1016\/j.neulet.2012.06.007"},{"key":"bibr13-1091581815583561","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2003.9200"},{"key":"bibr14-1091581815583561","doi-asserted-by":"crossref","unstructured":"Gilliom RJ, Barbash JE, Crawford CG, Pesticides in the Nation\u2019s Streams and Ground Water, 1992\u20132001.
