Item Geographic Information System: A Targeted Approach to Syphilis Elimination(2000-08-01) Morrison-Jones, June; Urrutia-Rojas, Ximena; Lurie, Sue; Oppong, JosephMorrison-Jones, June, Geographic Information System: A Targeted Approach to Syphilis Elimination. Master of Public Health, August 2000, 55 pp., 3 tables, 3 appendices, reference list, 25 titles. Syphilis is a sexually transmitted disease that has long caused a heavy public health and economic burden in the United States. With syphilis rates reaching their lowest recorded levels in the United States, Health officials are calling for an increased effort to eliminate the disease. In the United States, syphilis is also now extremely concentrated geographically, facilitating effective intervention. Most syphilis cases disproportionately affect a small portion of the population. African Americans who live below the poverty level, have limited access to health care, and have a number of social problems are also affected. This study examines the geographic distribution of syphilis and factors associated with syphilis transmission in Dallas County. The study used the techniques of geographic information system, principles of epidemiology, sociocultural linkages (race, ethnicity, and gender) between demographic factors and syphilis, to gain insights into the geographic distribution of syphilis among the affected groups, and intervention strategies for syphilis elimination were developed. These suggestions should assist the Dallas County Health Department in launching an effective syphilis elimination program. Results showed that zip codes with high incidence of cases were generally adjacent to each other. In addition, statistically significant results confirmed that poverty, minority-race ethnicity and geographic core areas are factors associated with the transmission of syphilis.Item Rural Vs. Urban Residents and Obesity in Texas(2005-05-01) Ohagi, Emeka J.; Ty Borders; Peter Hilsenrath; Kathryn CardarelliOhagi, Emeka J., Rural vs. Urban Residents and Obesity in Texas. Master of Public Health (Health Informatics), May 2005, 52 pp., 3 tables, bibliography, 90 titles. Obesity in the United States has been described as an epidemic and Texas has been identified as one of the most obese states in the country. The purpose of this study is to examine obesity among Texas adults in order to determine if there are differences in obesity levels based on residence, and to explore the influence of other demographic, socioeconomic, health and behavioral factors on the distribution of obesity. Results indicate that urban and suburban dwellers are less likely than rural dwellers to be obese (adj. OR=0.64; 0.68, respectively). However, residents of frontier communities have slightly higher odds of obesity (adj. OR=1.09) than rural residents. Age was found to be an important factor in obesity. It is hoped that these and other results will facilitate appropriate channeling of public health response.Item The Population Abundance and Associated Geographic and Demographic Factors of the Dengue Vectors, Aedes Aegypti and Aedes Albopictus in Dallas County, TX, USA(2007-05-01) Stahl, Matthew S.; Sue Lurie; Joon-Hak LeeStahl, Matthew S., The Population Abundance and Associated Geographic and Demographic factors of the Dengue Vectors Aedes aegypti and Aedes albopictus in Dallas County, TX. 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.
