Vertical Transmission Of West Nile Virus In Culex Spp. Mosquitoes Of Clark County, Nevada, Vivek K. Raman
Vertical Transmission Of West Nile Virus In Culex Spp. Mosquitoes Of Clark County, Nevada, Vivek K. Raman
UNLV Theses, Dissertations, Professional Papers, and Capstones
West Nile Virus (WNV) is an RNA arbovirus that cycles between mosquitoes and birds, but also infects and causes disease in humans, horses and other vertebrate species. Although most infections are asymptomatic, WNV has emerged as the most common cause of epidemic meningoencephalitis in North America and the leading cause of arboviral encephalitis in the United States.
Mosquitoes of the genus Culex are the most active vectors of WNV in North America. Approximately 85% of human WNV infections in the United States occur in late summer with a peak number of cases in August and September. Vertical transmission is defined …
Effects Of Environmental Prompts On Stair Usage, Lori Andersen
Effects Of Environmental Prompts On Stair Usage, Lori Andersen
UNLV Theses, Dissertations, Professional Papers, and Capstones
The objective of this study was to evaluate whether environmental prompts placed in two-story buildings on a university campus would increase stair usage. Three buildings were used. One served as a control, while the other two received an intervention. Participants of three buildings were observed taking the stairs and elevator for seven weeks. Baseline data was collected; signs were introduced, and then removed during this time period. Approximately 2700 observations were collected. Environmental prompts did not appear to increase stair usage. There were significant differences in the amount of stair users between buildings. The stair usage rates of this particular …

The Determinants Of Colorectal Cancer Survival Disparities In Nevada, Lucas N. Wassira
UNLV Theses, Dissertations, Professional Papers, and Capstones
Different population groups across Nevada and throughout the United States suffer disproportionately from colorectal cancer and its after-effects. Overcoming cancer health disparities is important for lessening the burden of cancer. There has been an overall decline in the incidence of and mortality from colorectal cancer (CRC). This is likely due, in part, to the increasing use of screening procedures such as Fecal Occult Blood Test (FOBT) and/or endoscopy, which can reduce the risk of CRC mortality by fifty percent. Nevertheless, screening procedures are routinely used by only fifty percent of Americans aged fifty years and older. Despite overall mortality decreasing …
The Influence Of Perspective And Gender On The Processing Of Narratives, Jeremy A. Houska
The Influence Of Perspective And Gender On The Processing Of Narratives, Jeremy A. Houska
UNLV Theses, Dissertations, Professional Papers, and Capstones
The overarching aim of this research was to examine potential boundary conditions to situation model construction (Experiment 1) and narrative-based persuasion (Experiment 3). Variables such as narrative perspective (i.e., 2nd or 3rd person) and matched characteristics with the reader (i.e., participant-protagonist gender match) were first examined using situation model updating (Experiment 1) and behavioral measures (Experiment 3) as dependent measures. It was expected that situation model updating would be more likely for narratives written in the 2nd person perspective and with a participant-protagonist gender match. It was uncertain, however, for health promotion narratives, whether these manipulations would increase the likelihood …
An Evaluation Of Lead In Imported Candies Within Clark County, Nevada, Usa, Lee Reuben Ibarra
An Evaluation Of Lead In Imported Candies Within Clark County, Nevada, Usa, Lee Reuben Ibarra
UNLV Theses, Dissertations, Professional Papers, and Capstones
Imported candies from Latin America pose a danger to children because of the potential for those candies to contain harmful levels of lead. This study sought to identify characteristics of imported candies that typically display higher concentrations of lead. This study also explored the Integrated Exposure Uptake Biokinetic model developed by the EPA. Using lead exposure data specific to Clark County, Nevada, the IEUBK model was used to estimate the amounts of candy a child would have to consume in order to raise his blood lead level to over 10µg/dL (the federal allowable limit).
The results showed that candies with …

Opportunities For Intervention: Characteristics Of Alcohol Related Visits To United States Emergency Departments, 2003 - 2007, Jonathon Lavalley
UNLV Theses, Dissertations, Professional Papers, and Capstones
The cycle of alcohol intoxicated patients passing through United States (US) emergency departments (ED) and repeated inpatient detoxification for alcohol inebriates is costly, as these patients are continually exposed to injury and other health and legal consequences of their continued at risk alcohol use. The high proportion of ED resources used by these alcohol intoxicated patients has contributed to increased patient wait times, increased ambulance diversions, forced closures of US EDs, increased numbers of patients leaving without being seen, and an overall reduction in the quality of medical services provided in the ED. In order to contribute to efforts towards …
Lead Risk Hazards In Pre-1978 Childcare Facilities Located In Clark County, Nevada, Usa, Jessica Marie Newberry
Lead Risk Hazards In Pre-1978 Childcare Facilities Located In Clark County, Nevada, Usa, Jessica Marie Newberry
UNLV Theses, Dissertations, Professional Papers, and Capstones
The harmful health effects of lead exposure have been known for centuries, yet lead is still produced and utilized in a variety of ways. There have been many movements to rid the environment of this toxic metal in hope to reduce the number of individuals who are and who may potentially be exposed. Lead exposure is responsible for a myriad of negative health effects most notably lowering IQ scores in children. Extensive amounts of data have been collected from areas of the country with known lead hazards, hazards that have been identified through hundreds of thousands of elevated blood lead …
Enhanced Food Marketing To Children On The Internet: A Content Analysis, Sarah A. Ochsner
Enhanced Food Marketing To Children On The Internet: A Content Analysis, Sarah A. Ochsner
UNLV Theses, Dissertations, Professional Papers, and Capstones
In light of the continuing epidemic of childhood obesity, aggressive food marketing strategies have come under increased scrutiny as a possible contributing factor. It has been acknowledged in numerous studies, that poor nutrient quality of food and beverages dominate children's programming. The growth in child-specific media envoys has further increased favorable opportunities to market food and beverages to children, notably less regulated and parentally unsupervised. According to the U.S. Census Bureau, 65% of children aged 6-11 have home access to the Internet; and today, the majority of food manufacturers operate websites appealing to children. The Institute of Medicine issued a …
Impacts On Maternal Diet In A Transitional Community In Rural Costa Rica: Potential Implications For The Developmental Origins Of Obesity-Related Disorders, Allison Cantor
UNLV Theses, Dissertations, Professional Papers, and Capstones
This thesis examines maternal diet in a rural, transitional community in Costa Rica. Using cross-cultural categories recognized in the ethnographic literature (i.e. dietary taboos, dietary prescriptions, food cravings and the acknowledgment of a special post-partum period diet), maternal dietary practices were identified in the local community through surveys (n=45) and participant-observation (n=5), and to reflect the actual consumption patterns of pregnant and nursing women in the area, 24-hour diet recalls were administered to 5 pregnant or nursing women. In light of the recent changes that increased tourism has brought to the Monteverde Zone, focus groups were employed to determine impacts …
Oral Cancer In Nevada: A Public Health Perspective, Karl Kingsley
Oral Cancer In Nevada: A Public Health Perspective, Karl Kingsley
UNLV Theses, Dissertations, Professional Papers, and Capstones
Cancer is the second leading cause of death in the United States, and oral cancer remains the eighth leading cause of cancer death among US males. Although previous epidemiologic studies have found that overall rates of cancer, including oral cancer, have declined in the US in recent decades – these declines are neither uniform nor consistent within this population. Anecdotal evidence has suggested that rates of oral cancer in Nevada are relatively high, although no evidence was available to support these assertions.
Oral Cancer Epidemiology: Based upon this information, a detailed and thorough epidemiologic examination of oral cancer rates in …
Relative Deprivation, Relative Gratification, Status, And Health, Samuel A. Holland
Relative Deprivation, Relative Gratification, Status, And Health, Samuel A. Holland
UNLV Theses, Dissertations, Professional Papers, and Capstones
The role of perceived inequity in health was assessed and compared to other social constructs predicted to be relevant in the relationship between inequity and health. Four studies were conducted that demonstrated that a social comparison-based measure of relative deprivation (RD) and relative gratification (RG) can predict health and continues to do so even after accounting for perceived stress, personal income, perceived control, and social participation. A measure of RD/RG was developed that was based on prominent social comparisons and objects of comparison. This measure was reliable and predictive of health in two samplings of different populations. Comparisons of the …
Factors Associated With Blood Lead Levels Of Children In Southern Nevada, Mackenzie Suzanne Burns
Factors Associated With Blood Lead Levels Of Children In Southern Nevada, Mackenzie Suzanne Burns
UNLV Theses, Dissertations, Professional Papers, and Capstones
Exposure to lead continues to be a public health concern, particularly for young children. The Centers for Disease Control and Prevention report that approximately 250,000 children currently have blood lead levels (BLLs) above the level at which adverse health effects are apparent and intervention is recommended (10μg/dL). National surveillance data on childhood lead exposure has been collected for children under the age of 6 years old since 1995. However, not until 2006 did a program begin in Nevada (limited to Clark County); therefore, statewide data about childhood lead exposure in Nevada remains limited. The goal of this study was to …

Access to health care is an important factor for the well-being of America's children. The principal goal of this study was examine the 2008-2009 Kindergarten Health Survey data to advance understanding and appreciation of the health status of children in addition to their discrepancies in accessing health care in the state of Nevada (n = 11,073). This dataset serves as a secondary data source to determine whether socio-demographic and medical factors are associated with disparity in accessing health care for children entering kindergarten. This study looked at both independent and combined effects of annual household income, race/ethnicity, primary language spoken …
Implementation Of The Wiegand Sun Safety Program Into Physicians’ Offices In Southern Nevada, Breanne Eddington
Implementation Of The Wiegand Sun Safety Program Into Physicians’ Offices In Southern Nevada, Breanne Eddington
UNLV Theses, Dissertations, Professional Papers, and Capstones
In this study Nevada Cancer Institute’s Wiegand Sun Safety Program was implemented in 14 clinics in Southern Nevada as a pilot run to increase awareness in children and their guardians through educational materials in pediatricians’ and family physicians’ offices. It was hypothesized that the increased display of information regarding sun safety and skin cancer in physicians’ offices would increase patient and guardian awareness of the subject and increase the likelihood of patients and/or guardians asking their physician questions about skin cancer and sun safety, resulting in an increase in preventive actions by guardians to protect their children from damaging rays …
Association Of Body Mass Index, Fruit And Vegetable Intake, And Acculturation In A Sample Las Vegas Hispanic Population, Anne L. Bolstad
Association Of Body Mass Index, Fruit And Vegetable Intake, And Acculturation In A Sample Las Vegas Hispanic Population, Anne L. Bolstad
UNLV Theses, Dissertations, Professional Papers, and Capstones
The U.S. is experiencing a rising prevalence of overweightedness that has been identified as the second leading cause for chronic health conditions threatening public health. Overweightedness has grown disproportionately among ethnic sub-groups. In the fastest going minority population in the U.S., Hispanic Americans are observed with disparately high body mass index, placing them at heightened risk for poor health outcomes. Research suggests five servings of fruit and vegetables, in any combination, provides a sound nutritional base for healthful living and helps to maintain normal body weight.
Americans are known to have poor eating habits while foreign-born populations have well balanced …

An Analysis Of Restaurant Food Safety Violations: Human Factors, Non-Human Factors, And Food-Borne Illness, Jai Choung
UNLV Theses, Dissertations, Professional Papers, and Capstones
An estimated 76 million food-borne illnesses occur in the United States each year, causing 325,000 hospitalizations and 5,000 deaths, according to the U.S. Food and Drug Administration. Food safety is an increasingly important topic to governmental food regulators, not only in trying to reduce the number of illnesses from contaminated food. Governmental regulators also are becoming aware of the vulnerability of the food supply chain as a target for bioterrorism. Recommendations have been developed to protect the U. S. food supply from terrorism, but little of the research and recommendations relate to the food-service level.
Eighty percent of reported cases …
