Description
The effects of a long-term combat deployment on a soldier's physical fitness are not well understood. In active duty soldiers, combat deployment reduced physical fitness compared to pre-deployment status, but no similar research has been performed on Army National Guard soldiers. This study is the first to identify physical fitness changes in Arizona National Guard (AZNG) soldiers following deployment to a combat zone and to assess the relationships between physical fitness and non-combat injuries and illness (NCII). Sixty soldiers from the Arizona National Guard (AZNG) completed a battery of physical fitness tests prior to deployment and within 1-7 days of returning from a 12-month deployment to Iraq. Pre and post-deployment measures assessed body composition (Bod Pod), muscular strength (1RM bench press, back-squat), muscular endurance (push-up, sit-up), power (Wingate cycle test), cardiorespiratory fitness (treadmill run to VO2 peak), and flexibility (sit-and-reach, trunk extension, shoulder elevation). Post deployment, medical records were reviewed by a blinded researcher and inventoried for NCII that occurred during deployment. Data were analyzed for changes between pre and post-deployment physical fitness. Relationships between fitness and utilization of medical resources for NCII were then determined. Significant declines were noted in mean cardiorespiratory fitness (-10.8%) and trunk flexibility (-6.7%). Significant improvements were seen in mean level of fat mass (-11.1%), relative strength (bench press, 10.2%, back-squat 14.2%) and muscular endurance (push-up 16.4%, sit-up 11.0%). Significant (p < 0.05) negative correlations were detected between percentage change in fat mass and gastrointestinal visits (r = -0.37); sit-and-reach and lower extremity visits (r= -0.33); shoulder elevation and upper extremity visits (r= -0.36); and cardiorespiratory fitness and back visits (r= -0.31); as well as behavioral health visits (r= -0.28). Cardiorespiratory fitness changes were grouped into tertiles. Those who lost the greatest fitness had significantly greater number of NCII visits (8.0 v 3.1 v 2.6, p = .03). These data indicate a relationship between the decline in cardiorespiratory fitness and an overall increase in utilization of medical resources. The results may provide incentive to military leaders to ensure that soldiers maintain their cardiorespiratory fitness throughout the extent of their deployment.

Description
The AIDS epidemic has tremendously impacted the population of Mozambique. The rate of newly infected young women continues to grow disproportionately which is why consideration of health interventions specific to this population to combat the spread of the disease is critical. The Health Belief Model emphasizes the importance of self efficiency in the process of health related behavioral changes. Previous research has found that low levels of autonomy increase one's risk of contracting HIV/AIDS. This research uses data from a study conducted in 2006 in Mozambique to test whether higher levels of autonomy are associated with the practice of self protective behaviors related to the contraction of HIV/AIDS. Results suggest that some measures of autonomy such as education are positively associated with the practice of self protective behaviors. However, higher levels of decision making powers were negatively associated with the practice of self protective behaviors.

Description
ABSTRACT In an attempt to advocate body-conscious design and healing work environments, this research study of holistic health in the workplace explores cognitive, social and physical well-being in four small US offices that are between 1000 and 4000 square feet and employ three to twelve employees. Holistic health, as pursued in this research, includes social health, emotional health and physical health. These three factors of holistic health have been identified and investigated in this study: biophilia: peoples' love and affiliation with other species and the natural environment; ergonomics: the relationship between the human body, movement, the immediate environment and productivity; and exercise: exertion of the body to obtain physical fitness. This research study proposes that employees and employers of these four participating workplaces desire mobility and resources in the workplace that support holistic health practices involving biophilia, ergonomics, and exercise. Literature review of holistic health and the holistic health factors of this research topic support the idea that interaction with other species can be healing, ergonomic body-conscious furniture and equipment increase productivity, limit body aches, pains and health costs; and exercise stimulates the mind and body, increasing productivity. This study has been conducted primarily with qualitative and flexible research approaches using observation, survey, interview and pedometer readings as methods for data collection. Two small corporate franchise financial institutions and two small private healthcare providers from both Arizona and Georgia participated in this study. Each office volunteered one employer and two employee participants. Of the holistic health factors considered in these four case studies, this study found that a majority of participants equally valued emotional health, social health and physical health. A majority of participants declared a preference for workplace environments with serene natural environments with outdoor spaces and interaction with other species, work environments with body-conscious furniture, equipment and workstations, as well as exercise space and equipment. As these particular workplace environments affirmed value for elements of the factors biophilia, ergonomics and exercise, all three factors are considered valueable within the workplaces of these case studies. Furthermore, factors that were said to contribute to personal productivity in participating workplaces were found as well as sacrifices that participants stated they would be willing to make in order to implement their preferred work environment(s). In addition, this study recorded and calculated average miles walked by participants in each workplace as well as existing incentives and descriptions of ideal work environments. Implications of this research study involve interior design, industrial design and fashion design that can accommodate the desires of the four participating workplaces. Major design implications involve accommodating these particular workplaces to provide personnel with opportunities for holistic health in working environments. More specific implications of office related design involve providing access to natural environments, body-conscious equipment and spaces, as well as opportunities for exercise and social interaction. These elements of the factors biophilia, ergonomics and exercise were found to be said to contribute to cognitive, social and physical health.

Description
Other studies have previously demonstrated that perceived stress and maladaptive stress management can lead to harmful outcomes including depression, morbidity, and mortality. College students (especially freshmen) have more difficulty dealing with stress, which can increase their susceptibility to engage in high risk behaviors. The importance of conducting this research is to discover the effects that perceived stress levels may have on depression outcomes in college students, and to evaluate the influence of health related behaviors on this relationship. This study used a retrospective cross-sectional correlational design to examine correlations between perceived stress, physical activity, and other health behaviors on clinical and perceived depression in college students. A random sample of 20,000 students was drawn from 62,476 students enrolled at Arizona State University (ASU). Participants included 2,238 students who volunteered to take the American College Health Association-National College Health Assessment (ACHA-NCHA) in spring 2009. Supplemental questions for ASU students were developed by ASU Wellness and administered as a part of the ACHA-NCHA II. The university sent an invitation email, wherein students were directed through a hyperlink to the survey website. ACHA provided institutional survey data in an SPSS file for analysis. The data were evaluated with Spearman Rho Correlation Analysis and Wilcoxon-Mann-Whitney test. There were more female participants (n = 580) than males (n = 483), both averaged 23 years of age. Men had greater height, weight, and body mass index than females, all were significant mean differences. There were more significant correlations between health factors and having perceived depression than with having real or diagnosed depression. Logistic regression showed that out of all variables and behaviors studied, only high levels of stress, poor general health, substance use, and gender (female) resulted in significant odds in predicting that a participant would be in one of the depression categories. This research suggests that addressing these factors may be important to prevent and reduce depression among college students. This study provides empirical evidence that there is a significant relationship between perceived stress and depression among college students, and that health behaviors such as substance abuse have a negative mediating effect on this relationship.

Description
In the search for chemical biosensors designed for patient-based physiological applications, non-invasive diagnostic approaches continue to have value. The work described in this thesis builds upon previous breath analysis studies. In particular, it seeks to assess the adsorptive mechanisms active in both acetone and ethanol biosensors designed for breath analysis. The thermoelectric biosensors under investigation were constructed using a thermopile for transduction and four different materials for biorecognition. The analytes, acetone and ethanol, were evaluated under dry-air and humidified-air conditions. The biosensor response to acetone concentration was found to be both repeatable and linear, while the sensor response to ethanol presence was also found to be repeatable. The different biorecognition materials produced discernible thermoelectric responses that were characteristic for each analyte. The sensor output data is presented in this report. Additionally, the results were evaluated against a mathematical model for further analysis. Ultimately, a thermoelectric biosensor based upon adsorption chemistry was developed and characterized. Additional work is needed to characterize the physicochemical action mechanism.

Description
Many studies have shown that access to healthy food in the US is unevenly distributed and that supermarkets and other fresh food retailers are less likely to be located in low-income minority communities, where convenience and dollar stores are more prevalent grocery options. I formed a partnership with Phoenix Revitalization Corporation, a local community development organization engaged in Central City South, Phoenix, to enhance the community's capacity to meet its community health goals by improving access to healthy food. I used a community-based participatory approach that blended qualitative and quantitative elements to accommodate collaboration between both academic and non-academic partners. Utilizing stakeholder interviews, Nutrition Environment Measures Surveys (NEMS), and mapping to analyze the community's food resources, research revealed that the community lacks adequate access to affordable, nutritious food. Community food stores (n=14) scored an average of 10.9 out of a possible 54 points using the NEMS scoring protocol. The community food assessment is an essential step in improving access to healthy food for CCS residents and provides a baseline for tracking progress to improve residents' food access. Recommendations were drafted by the research partnership to equip and empower the community with strategic, community-specific interventions based on the research findings.

Description
Titanium dioxide (TiO2) nanomaterial use is becoming more prevalent as is the likelihood of human exposure and environmental release. The goal of this thesis is to develop analytical techniques to quantify the level of TiO2 in complex matrices to support environmental, health, and safety research of TiO2 nanomaterials. A pharmacokinetic model showed that the inhalation of TiO2 nanomaterials caused the highest amount to be absorbed and distributed throughout the body. Smaller nanomaterials (< 5nm) accumulated in the kidneys before clearance. Nanoparticles of 25 nm diameter accumulated in the liver and spleen and were cleared from the body slower than smaller nanomaterials. A digestion method using nitric acid, hydrofluoric acid, and hydrogen peroxide was found to digest organic materials and TiO2 with a recovery of >80%. The samples were measured by inductively coupled plasma-mass spectrometry (ICP-MS) and the method detection limit was 600 ng of Ti. An intratracheal instillation study of TiO2 nanomaterials in rats found anatase TiO2 nanoparticles in the caudal lung lobe of rats 1 day post instillation at a concentration of 1.2 ug/mg dry tissue, the highest deposition rate of any TiO2 nanomaterial. For all TiO2 nanomaterial morphologies the concentrations in the caudal lobes were significantly higher than those in the cranial lobes. In a study of TiO2 concentration in food products, white colored foods or foods with a hard outer shell had higher concentrations of TiO2. Hostess Powdered Donettes were found to have the highest Ti mass per serving with 200 mg Ti. As much as 3.8% of the total TiO2 mass was able to pass through a 0.45 um indicating that some of the TiO2 is likely nanosized. In a study of TiO2 concentrations in personal care products and paints, the concentration of TiO2 was as high as 117 ug/mg in Benjamin Moore white paint and 70 ug/mg in a Neutrogena sunscreen. Greater than 6% of Ti in one sunscreen was able to pass through a 0.45 um filter. The nanosized TiO2 in food products and personal care products may release as much as 16 mg of nanosized TiO2 per individual per day to wastewater.

Description
Cardiovascular disease is one of the most deadly outcomes of end stage renal disease. Bioelectrical impedance is a intriguing, yet unproven method of measuring fluid buildup in the heart, and is marketed as a early diagnostic tool for onset of cardiovascular disease. In this study, selenium supplements were given to a cohort of dialysis patients in the Phoenix metro area and their fluid tolerance was measured with thoracic biolectrical impedance. BNP was used as a correlate to see if bioelectrical impedance was correlated with heart disease. The study found no correlation between BNP and bioelectrical impedance and thus was not an accurate diagnostic tool in a medical setting.

Description
Medical practice surrounding tuberculosis (TB) treatment in two nineteenth-century Scottish charitable hospitals reveals that in developing empirically-positioned constructs of this and related diseases, medical practitioners drew upon social assumptions about women and the working classes, thus reinforcing rather than shedding cultural notions of who becomes ill and why. TB is a social disease, its distribution determined by relationships among human groups; primary among these is the patient-practitioner relationship, owing to the social role of medical treatment in restoring the ill to both health and society. To clarify the influence of cultural context upon the evolution of medical constructs of TB, I examined Glasgow Royal Infirmary (GRI) and Royal Infirmary of Edinburgh (RIE) ward journals, admissions registers, and institution management records from 1794 through 1905. Medical practice at the turn of the nineteenth century was dominated by observation and questioning of the patient, concordant with conceptions of physicians' labor as mental rather than physical. This changed with the introduction of the stethoscope in the 1820s, which together with the dissection of the poor allowed by the 1832 Anatomy Act ushered in disease concepts emphasizing pathological anatomy. Relationships between patient and practitioner also altered at this time, exhibiting distrust and medical dominance. The mid-Victorian era was notable for clinicians' increasing interest in immorality's contributions to ill health, absent in earlier practice and linked to conceptions of women and the working classes as inherently pathological. In 1882, discovery of the tubercle bacillus challenged existing nutritional, hereditary, and environmental explanations for TB. Although practitioners utilized bacteriological methods, this discovery did not revolutionize diagnosis or treatment. Rather, these older models were incorporated with perceived behavioral, environmental, and biological degradation of the working classes, rendering marginalized groups "soil" prepared for the "seeds" of disease -- at risk, but also to blame. This framework, in which marginalized groups contribute to their increased risk for disease through refusal to accord with hegemonically-established "healthy" behavior, persists. As a result, meaningful change in TB rates will need to address these longstanding contributions of social inequality to Western medical treatment.

Description
In 1890, the State of Nevada built the Stewart Indian School on a parcel of land three miles south of Carson City, Nevada, and then sold the campus to the federal government. The Stewart Indian School operated as the only non-reservation Indian boarding school in Nevada until 1980 when the federal government closed the campus. Faced with the challenge of assimilating Native peoples into Anglo society after the conclusion of the Indian wars and the confinement of Indian nations on reservations, the federal government created boarding schools. Policymakers believed that in one generation they could completely eliminate Indian culture by removing children from their homes and educating them in boarding schools. The history of the Stewart Indian School from 1890 to 1940 is the story of a dynamic and changing institution. Only Washoe, Northern Paiute, and Western Shoshone students attended Stewart for the first decade, but over the next forty years, children from over sixty tribal groups enrolled at the school. They arrived from three dozen reservations and 335 different hometowns across the West. During this period, Stewart evolved from a repressive and exploitive institution, into a school that embodied the reform agenda of the Indian New Deal in the 1930s. This dissertation uses archival and ethnographic material to explain how the federal government's agenda failed. Rather than destroying Native culture, Stewart students and Nevada's Indian communities used the skills taught at the school to their advantage and became tribal leaders during the 1930s. This dissertation explores the individual and collective bodies of Stewart students. The body is a social construction constantly being fashioned by the intersectional forces of race, class, and gender. Each chapter explores the different ways the Stewart Indian School and the federal government tried to transform the students' bodies through their physical appearance, the built environment, health education, vocational training, and extracurricular activities such as band and sports.
