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 …

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 …

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 …

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 …

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 …

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 …

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 …

Attitudes Of Young Adults About Breastfeeding And The Association Of Breastfeeding Exposure, Cheryl Lynn Darby-Carlberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

The theory for reasoned action was used as the framework to guide the study. This theory explains deliberate behavior and how specific behaviors, such as breastfeeding, are affected by individual attitudes and social support. The research is a cross-sectional correlational study and sought to test two null hypotheses: (1) There is no association between previous exposure to breastfeeding and positive attitudes toward breastfeeding, and (2) There is no …

The Effects Of Cellular Theta Breathing Meditation On Cell Mediated Immune Response: A Controlled, Randomized Investigation Of Altered Consciousness And Health, Marjorie D. Hardgrave

UNLV Theses, Dissertations, Professional Papers, and Capstones

Medical anthropology is well positioned to make contributions to consciousness research based on biocultural approaches that integrate methodologies from the biological, behavioral and social sciences to explore aspects of human health. The ubiquity and perseverance of health related activities involving altered states of consciousness (ASC) across cultures past and present suggest that these potentials are deeply rooted in human sociocultural evolution. Analyzing the relationship between immune function and meditative ASC represents an effort to empirically investigate the adaptive value of these human potentials.

A controlled, randomized investigation of two meditation practices was conducted at the University of Nevada, Las Vegas …

The Role Of Visual, Vestibular, And Somatosensory Systems In Postural Balance, Mary Grace Gaerlan

UNLV Theses, Dissertations, Professional Papers, and Capstones

The integration of visual, vestibular, and somatosensory components are used to maintain one's postural balance. Postural control changes over time and body sway increases with age. The different sensory systems begin to develop and refine starting when children are young, while in older adults it begins to decline. Hence, it is important to study the changes that occur in postural balance. There is very little known about balance of younger adults. If balance issues are identified early in adult life it is possible to prevent exacerbation of balance decline as one ages. If nurse practitioners are aware of what dominant …
