Association Among Obesity-Related Anthropometric Phenotypes: Analyzing Genetic And Environmental Contribution, Aline Jelenkovic, Esther Rebato

Human Biology Open Access Pre-Prints

Obesity has become a public health and policy problem in many parts of the world. Epidemiological and population studies in this field are usually based on different anthropometric measures, however, common genetic and environmental factors between these phenotypes have been scarcely studied. The objective of this work is to assess the strength of these factors on the covariation among a large set of obesity-related traits. The subject group consisted of 533 nuclear families living in the Greater Bilbao (Spain), and included 1702 individuals aged 2-61 years. Detailed anthropometric measurements (stature, breadths, circumferences and skinfolds) were carried out in each subject. …

Curative Care As The Access Point To Rural Social Transformation A Case Study Of The Comprehensive Rural Health Project, Nancy Liu

Independent Study Project (ISP) Collection

Health inequities based on geographic differences and between rural and urban populations in modern India demonstrate the stark differences in health access and community development throughout the country. More than 70% of the Indian population lives in rural areas, and yet a greater proportion of health care spending is devoted to urban populations. In 2004-5, 29.2% of both central and state public expenditures were allocated to urban allopathic services while 11.8% went to rural allopathic services (Balarajan, Selvaraj, and Subramanian 2011, 508). There are more than twice as many government beds in urban than in rural areas and geographic distribution …

Linking Authentic Leadership To Positive Employee Health, Behavioral Engagement, And Job Performance, Yan Liu

Doctoral Dissertations

In recent years, there has been increasing interest in the emerging field of positive organizational behavior. The field of Positive Organizational Behavior (POB) has its roots in the concept of "positive psychology" (Bakker & Schaufeli, 2008) but is more narrowly defined as "the study and application of positively oriented human resources strengths and psychological capacities that can be measured, developed, and effectively managed for performance improvement in today's workplace" (Luthans, 2002, p.698). More and more researchers have begun to emphasize what is right with people rather than focusing on what is wrong with people.

Given this opportunity, this dissertation explicitly …

Community Gardening: Benefits Focused Strategies, Joseph Zaanan Tellschow

UNLV Theses, Dissertations, Professional Papers, and Capstones

Throughout history humans have had varying degrees of interaction with nature and natural environments. This interaction has shaped our species in almost every way possible from our physical traits to our behaviors and places we have chosen to occupy. Currently, humans have developed such overwhelming mastery of the planet that it is easy for many humans to feel disconnected from nature. This separation could have detrimental effects on various aspects of human well-being including physical and mental health. To understand these effects, it is important to evaluate the benefits that humans receive from exposure to nature and interaction with natural …

Road Construction As A Facilitator For Dengue Fever Transmission, Kate Billups

Environmental Studies Senior Seminar Projects

Although I plan to focus on the impact of road construction in tropical and subtropical regions on the spread and contraction of dengue fever, I hope to use this focus as a model that could help to create policies that would mitigate other diseases spread through insect contact. In places that road and railway construction have already become a part of the permanent foundation, medical infrastructure should be put into place to ensure that populations at increased risk to contract dengue fever have access to medical care to diminish rates of dengue hemorrhagic fever.

Facing An Epidemic: An Analysis Of Hiv/Aids, Antiretroviral Drug, And International Response To The Aids Pandemic, Michael Tate

Annual Undergraduate Conference on Health and Society

More than 33 million people are living with HIV/AIDS around the globe with 68% of all cases occurring in sub-Saharan Africa. The global prevalence rate is shocking considering that the disease was relatively unknown just 30 years ago. After reviewing medical, health policy, and health statistical journals, I will argue in this paper that international aid to nations struggling with AIDS needs to be redirected and refocused on supplying antiretroviral therapy to afflicted nations because ARV has been proven to be effective in managing the disease in countries that can afford the costs of treatment. International aid to countries that …

Social Capital And Violence Across Racial And Ethnic Samples Of Adolescents, Darlene R. Haff, Kevin M. Fitzpatrick, H. H. Floyd

Journal of Health Disparities Research and Practice

Using a national sample of adolescents, results of this study demonstrate the important role family and school social capital plays in protecting both White and selected non- White students against violent outcomes. For example, parent-child relationship was associated with reduced violence for Black and White adolescents but not for Hispanics. School affiliation was significant in models for Hispanic and White adolescents but not in models for Black students. Sports participation was associated with greater violence among Hispanics and Whites, but not Blacks. Interestingly, club participation was significant for Whites, but, like sports, it was associated with greater violence. Parental monitoring …

Not Always Black And White: Racial Bias For Birth Disparities From Excluding Hispanic Identification, Barbara L. Wilson, Cristi Coursen, Matthew Butler

Journal of Health Disparities Research and Practice

Despite gains in prenatal care (PNC) usage and birth outcomes for minority women during the past few decades, observed disparities between non-Hispanic Whites, Blacks, and Hispanics persist. Using the National Center for Health Statistics’ (NCHS) natality files from 1981 through 1998, Alexander, Kogan, & Nabukera (2002) examined live births of U.S. residents by trimester in which PNC was initiated and the appropriateness of that care based on the Adequacy of Prenatal Care Utilization Index (APNCU) (Kotelchuck, 1994). They found racial disparities between White and Black women in both the trimester of PNC initiation and the number of PNC visits made. …

Asthma Management: An Ecosocial Framework For Disparity Research, Robin A. Evans-Agnew

Journal of Health Disparities Research and Practice

Background: Asthma management disparities (AMD) between African and White Americans are significant and alarming. Various determinants have been suggested by research frameworks that affect the unfair distribution of resources for asthma management to groups who are more or less advantaged socially. Ecosocial models organize determinants into individual/family, healthcare, community, and sociocultural levels. Multilevel interventions can affect AMD through simultaneous actions on different levels and pathways between determinants.

Objective: Provide a comprehensive summary of the known determinants of AMD.

Method: Peer reviewed research frameworks of AMD from 1998-2009 were retrieved from PubMed/ Web of Science databases using (“Socioeconomic Factors”[Mesh] OR (“Healthcare …

Probabilistic Model For Laser Damage To The Human Retina, David A. Wooddell Jr.

Theses and Dissertations

Understanding how lasers interact with media during propagation is a premiere field of physics. The subject area known as laser bioeffects explores laser interactions with biological cells, tissues, organs, and bodies. This research includes laser applications used in medicine, establishes safe exposure limits for industry and academia, and generally studies the many effects of laser light on living creatures. The bioeffects community relies heavily on deterministic modeling and simulation tools to support experimental research into damage thresholds and laser effects. However, recent laser applications require a probabilistic approach to support risk management and analyses methodologies. Some probabilistic models exist, but …

Comparative Analysis Of Two Biological Warfare Air Samplers Using Live Surrogate Agents, James C. Enderby

Theses and Dissertations

The United States Air Force has several high-volume biological air samplers, including the XMX/2L-MIL and the Biocapture 650. Limited information is available on either in terms of its collection of viruses and bacteria. However, previous research on the XMX/2L-MIL has determined that modifications to the secondary flow rate and the use of a virus preserving collection media may provide improved virus collection rates. In this thesis, these modifications were investigated to determine their impact on the collection of viral and bacterial aerosols. Additionally, relative collection rates were compared against those for the Biocapture 650. MS2 bacteriophage was the viral surrogate …

Methods. Mortality rates, poverty rates, Appalachian designation and mining activity were examined for counties in Kentucky, Tennessee, Virginia and West Virginia (N=403). Linear least squares models tested for annual group differences from 2000-2007 in total and child poverty, and total mortality, based on mining type and Appalachian location. Nested linear models accounting for state-level …

Responding To American Indian Communities: Southwest American Indian Collaborative Network (Saicn) Cancer Educational Activities, Naomi A. Lane, Kathleen Evans, Agnes Attakai, Catherine Witte, Maylynn Riding In-Warne, Kathryn Coe

Journal of Health Disparities Research and Practice

Developing educational materials and providing trainings in American Indian communities is a highly rewarding activity. However, to do so successfully a number of complex issues must be faced and cultural-tailored strategies to promote awareness must be developed based on the unique traditions of each tribe. In this paper we describe the educational activities conducted over a four year period by the Southwest American Indian Collaborative Network, a project funded by the National Cancer Institute’s Center to Reduce Cancer Health Disparities. Activities fell into two broad areas: dissemination of cancer information through trainings and workshops and development of culturally-tailored educational materials.

Preventive Medicine and Environmental Health Faculty Publications

BACKGROUND: Fibrinogen is a marker of systemic inflammation and may be important in the pathogenesis and progression of chronic obstructive pulmonary disease (COPD).

METHODS: We used baseline data from Atherosclerosis Risk in Communities and Cardiovascular Health Studies to determine the relation between fibrinogen levels and COPD and to examine how fibrinogen levels at baseline affected outcomes of death, development of COPD, lung function decline, and COPD-hospitalizations.

RESULTS: Our study sample included 20,192 subjects, of whom 2995 died during the follow-up period. The mean fibrinogen level was 307.6 mg/dL and 10% of the sample had levels >393.0 mg/dL. Subjects with Stage …

Hurricane Preparedness Of Community-Dwelling Dementia Caregivers In South Florida, Janelle J. Christensen

USF Tampa Graduate Theses and Dissertations

The aim of this dissertation is to explore how informal caregivers for people with dementia (PWD), who are community dwelling (i.e., not in nursing homes), prepare and plan for disasters. The research site is a particularly hurricane-prone region of Florida, second only to New Orleans in its vulnerability. An underlying assumption of this research is that caregivers for PWD have to plan and anticipate problems that are unique to their role. The rationale for the study described here is that disaster planning and mitigation save lives (Tengs et al. 1995), but there is little or no literature on disaster planning …

Detection And Imaging Of The Free Radical Dna In Cells—Site-Specific Radical Formation Induced By Fenton Chemistry And Its Repair In Cellular Dna As Seen By Electron Spin Resonance, Immuno-Spin Trapping And Confocal Microscopy, Suchandra Bhattacharjee, Saurabh Chatterjee, Jinjie Jiang, Birandra K. Sinha, Ronald P. Mason

Faculty Publications

Oxidative stress-related damage to the DNA macromolecule produces lesions that are implicated in various diseases. To understand damage to DNA, it is important to study the free radical reactions causing the damage. Measurement of DNA damage has been a matter of debate as most of the available methods measure the end product of a sequence of events and provide limited information on the initial free radical formation. We report a measurement of free radical damage in DNA induced by a Cu(II)-H2O2 oxidizing system using immuno-spin trapping supplemented with electron paramagnetic resonance. In this investigation, the short-lived radical generated is trapped …

Evaluation Of Urinary Pesticide Biomarkers Among A Sample Of The Population In The United States, Alex Lance Lebeau

USF Tampa Graduate Theses and Dissertations

Pesticide use in the United States continues to attract negative public attention. In recent years, this attention has focused on the effects that chronic, low-level pesticides may have, especially on children and various sub-populations. Over the past decade, studies have attempted to correlate negative health effects with detections of pesticide biomarkers in biological media. The current research investigates biomarker of exposure levels in a sample of the United States population. Data from the 2001-2002 NHANES dataset (n=11,039) was evaluated. The detection frequency of urinary biomarkers of exposure and the geometric mean from the NHANES pesticide dataset (n=3,152) were determined. Of …
