Master of Public Health (Environmental Health), May 2007, 40 pp., 7 figures, 2 tables, bibliography, 72 titles. The risk for dengue outbreak was assessed in North Central Texas in 2006 in response to increased case numbers in Texas and Mexican states in 2005. Data were collected from 54 sites in Dallas County, TX using oviposition traps and estimates from U.S. Census and Sourcebook America databases. Higher vegetation and shade displayed more Aedes species; standing water also showed more Aedes albopictus. Lower home values and lower incomes corresponded to more Aedes aegypti; lower household density displayed more Aedes albopictus. Other socio-economic and demographic factors did not have significant association with abundance. The methodology of this study may serve as a model for assessment of dengue vector abundance in other regions.Item The Relationship Between Atrazine Exposure and Breast and Ovarian Cancer Incidence Rates in Texas Agricultural Statistical Districts(2006-05-01) Hull, Kimberly M.; Terrance Gratton; Eric Johnson; Sejong BaeHull, Kimberly M., The Relationship Between Atrazine Exposure and Breast and Ovarian Cancer Incidence Rates in Texas Agricultural Statistical Districts. Masters of Public Health (Environmental Health), May 2006, 95pp., 16 tables, 7 illustrations, reference, 74 titles. The herbicide, atrazine, is suspected to cause cancer primarily through drinking water. This ecological study analyzed relationships between potential atrazine exposures and female breast and ovarian cancer incidence rates in Texas Agricultural Statistical Districts. Atrazine exposures are: atrazine usage, rural population, and public water systems. Study results indicate an inverse relationship between four atrazine exposures and breast and ovarian cancer incidence rates (county level). There is a positive relationship between surface water systems and ovarian cancer incidences rates (county level). There also is an inverse relationship between one atrazine usage index and ovarian cancer incidence rates (district level). Study results are similar to other atrazine and cancer studies; correlations prevent statements of causal inference.
