History Of Pregnancy Termination As A Risk Factor For Preterm Birth, Virginia 2000-20007, Jennifer Macdonald May 2009

History Of Pregnancy Termination As A Risk Factor For Preterm Birth, Virginia 2000-20007, Jennifer Macdonald

Theses and Dissertations

Abstract Objectives: The objective of this study was to determine if an association exists between prior induced and prior spontaneous pregnancy termination (PIPT and PSPT) and preterm birth (PTB) of first live births in Virginia. Methods: Data was collected by linking maternal data from Virginia’s live birth and fetal death registries. All first live, singleton births occurring in Virginia from 2000-2007 were analyzed. Logistic regression models that controlled for various demographic, medical and obstetric history factors were used to determine associations among prior pregnancy termination types. Results: Compared with women who had no history of previous pregnancy terminations, women who …

Perception Of Power Dynamics And Risky Sexual Behavior In Indian Men, Amber Haley May 2009

Perception Of Power Dynamics And Risky Sexual Behavior In Indian Men, Amber Haley

Theses and Dissertations

Background: Women account for about a third of all new cases of HIV in India. Based on research examining trends of HIV infection in women, male perception and behaviors have emerged as strong potential risk factors. However, there has been limited research examining the relationship between male’s attitudes toward women and their sexual risk-taking behaviors. This study examined the degree to which men’s beliefs about power dynamics in heterosexual relationships are related to risky sexual behaviors in Indian men. Methods: Data on Indian men from the 2005-2006 National Family Health Survey (NFHS-3) was analyzed (N= 44,727). The outcome variable, risky …


A Culturally-Relevant, Emergent Approach To Exploring The Needs, Strengths, And Priorities Of Tribal Communities In Virginia, Amy Prorock-Ernest May 2009

A Culturally-Relevant, Emergent Approach To Exploring The Needs, Strengths, And Priorities Of Tribal Communities In Virginia, Amy Prorock-Ernest

Theses and Dissertations

Little is known about the health of the indigenous peoples in Virginia. When compared to the total U.S. population, indigenous peoples nationwide disproportionately experience disparities in health status across multiple health indicators. Research shows that these disparities are largely due to the inequitable distribution of social and economic determinants present within indigenous communities. Because the indigenous peoples of Virginia are affected by inequitable social and economic conditions, there is reason to believe that health indicators may mirror that of the indigenous population at-large. Outlined in this paper is a framework for exploring the needs, strengths, and priorities of indigenous communities …

Hiv/Aids Di Indonesia : Fenomena Gunung Es Dan Peranan Pelayanan Kesehatan Primer, Hardisman Hardisman Apr 2009

Hiv/Aids Di Indonesia : Fenomena Gunung Es Dan Peranan Pelayanan Kesehatan Primer, Hardisman Hardisman

Kesmas

Masalah HIV/AIDS di Indonesia diyakini bagaikan fenomena gunung es karena laporan resmi jumlah kasus tidak mencerminkan masalah yang sebenarnya. Prediksi besar masalah HIV/AIDS tersebut didasarkan atas jumlah penyalahgunaan narkotika suntik dan prostitusi yang tinggi. Keduanya merupakan faktor utama yang berperan sangat besar dalam penyebaran dan penularan HIV. Berbagai faktor risiko tersebut tidak hanya berkaitan dengan pelayanan keseha-tan tetapi juga dengan masalah sosial ekonomi. Permasalahan tersebut perlu diatasi dengan pendekatan pelayanan kesehatan primer komprehensif yang langsung menyentuh akar permasalahan mencakup masalah sosial ekonomi dan lingkungan kultural. Strategi tersebut dilakukan melalui berbagai langkah yang bersifat menyeluruh, meliputi preventif, promotif, kuratif dan rehabilitatif …


Physical Activity Levels Of Older Community-Dwelling Adults Are Influenced By Summer Weather Variables, Caitlin A. Brandon, Dawn P. Gill, Mark Speechley, Jason Gilliland, Gareth R. Jones Apr 2009

Physical Activity Levels Of Older Community-Dwelling Adults Are Influenced By Summer Weather Variables, Caitlin A. Brandon, Dawn P. Gill, Mark Speechley, Jason Gilliland, Gareth R. Jones

Geography & Environment Publications

Adequate daily physical activity (PA) is important for maintaining functional capacity and independence in older adults. However, most older adults in Canada do not engage in enough PA to sustain fitness and functional independence. Environmental influences, such as warmer daytime temperatures, may influence PA participation; however, few studies have examined the effect of summertime temperatures on PA levels in older adults. This investigation measured the influence of summertime weather variables on PA in 48 community-dwelling older adults who were randomly recruited from a local seniors’ community centre. Each participant wore an accelerometer for a single 7-consecutive-day period (between 30 May …


Tuberculosis Por Los Ojos De La Vida Aymara: La Correlación Entre Estilo De Vida Y Tuberculosis En Los Aymara Del Norte De Chile, Sam Percy Apr 2009

Tuberculosis Por Los Ojos De La Vida Aymara: La Correlación Entre Estilo De Vida Y Tuberculosis En Los Aymara Del Norte De Chile, Sam Percy

Independent Study Project (ISP) Collection

Background: Explanations for disparities in health between groups of people are complex, and based in differences in genetics, environment, access to medical care, socioeconomic, educational, and cultural factors. In short a person’s lifestyle is inextricably related to a person’s health and their propensity to contract disease. Members of the indigenous group Aymara who live in Arica, Chile have 6 times the rate of morbidity from Tuberculosis (TB) as non-Aymara and 9 times the rate of mortality from the disease. This study examined if there was a link between the rate of TB amongst the Aymaran people and the way Aymarans …


Nonparametric Incidence Estimation From Prevalent Cohort Survival Data, Marco Carone, Masoud Asgharian, Mei-Cheng Wang Mar 2009

Nonparametric Incidence Estimation From Prevalent Cohort Survival Data, Marco Carone, Masoud Asgharian, Mei-Cheng Wang

COBRA Preprint Series

Incidence is an important epidemiologic concept particularly useful in assessing an intervention, quantifying disease risk, and planning health resources. Incident cohort studies constitute the gold-standard in estimating disease incidence. However, due to material constraints, data are often collected from prevalent cohort studies whereby diseased individuals are recruited through a cross-sectional survey and followed forward in time. We discuss the identifiability of measures of incidence in the context of prevalent cohort survival studies and derive nonparametric maximum likelihood estimators and their asymptotic properties. The proposed methodology accounts for calendar-time and age-at-onset variation in disease incidence while also addressing common complications arising …


The Importance Of Scale For Spatial-Confounding Bias And Precision Of Spatial Regression Estimators, Christopher J. Paciorek Mar 2009

The Importance Of Scale For Spatial-Confounding Bias And Precision Of Spatial Regression Estimators, Christopher J. Paciorek

Harvard University Biostatistics Working Paper Series

Increasingly, regression models are used when residuals are spatially correlated. Prominent examples include studies in environmental epidemiology to understand the chronic health effects of pollutants. I consider the effects of residual spatial structure on the bias and precision of regression coefficients, developing a simple framework in which to understand the key issues and derive informative analytic results. When the spatial residual is induced by an unmeasured confounder, regression models with spatial random effects and closely-related models such as kriging and penalized splines are biased, even when the residual variance components are known. Analytic and simulation results show how the bias …

Sand Fly Fever: What Have We Learned In One Hundred Years?, David Brett-Major, David M. Claborn Jan 2009

Sand Fly Fever: What Have We Learned In One Hundred Years?, David Brett-Major, David M. Claborn

Journal Articles: Epidemiology

Sand fly fever has severely impacted military missions in southern Europe and the Middle East for hundreds of years. After a brief respite following the malaria eradication programs of World War II, it has returned as a significant disease among residents in and travelers to the Mediterranean rim. It is a more severe disease now, with potential vectors in the United States. Sand fly fever is discussed in terms of its viruses, vectors, disease, control, and potential domestic impact.

Foodborne Or Pandemic: An Analysis Of The Transmission Of Norovirus-Associated Gastroenteritis And The Role Of Food Handlers, M. S. Dreyfuss Jan 2009

Foodborne Or Pandemic: An Analysis Of The Transmission Of Norovirus-Associated Gastroenteritis And The Role Of Food Handlers, M. S. Dreyfuss

Walden Dissertations and Doctoral Studies

This study examined the strength of association between food workers and food to norovirus in comparison to bacteria associated with foodborne-related gastroenteritis by whether norovirus had a direct (physical evidence), indirect (statistical evidence), or suspect (neither of the two) association with food or food handlers. The Centers for Disease Control and Prevention considers norovirus to cause the largest number of foodborne-related gastroenteritis cases in the United States. The association of norovirus with foodborne outbreaks through its information data collection form focuses on the food worker as the typical source. Yet, many outbreaks are not foodborne in nature. The gap in …

Validation Of Inverse Seasonal Peak Mortality In Medieval Plagues, Including The Black Death, In Comparison To Modern Yersinia Pestis-Variant Diseases, Mark R. Welford, Brian H. Bossak Jan 2009

Validation Of Inverse Seasonal Peak Mortality In Medieval Plagues, Including The Black Death, In Comparison To Modern Yersinia Pestis-Variant Diseases, Mark R. Welford, Brian H. Bossak

Earth, Environment & Sustainability: Faculty Publications

Background: Recent studies have noted myriad qualitative and quantitative inconsistencies between the medieval Black Death (and subsequent ‘‘plagues’’) and modern empirical Y. pestis plague data, most of which is derived from the Indian and Chinese plague outbreaks of A.D. 1900615 years. Previous works have noted apparent differences in seasonal mortality peaks during Black Death outbreaks versus peaks of bubonic and pneumonic plagues attributed to Y. pestis infection, but have not provided spatiotemporal statistical support. Our objective here was to validate individual observations of this seasonal discrepancy in peak mortality between historical epidemics and modern empirical data.

When To Spray: A Time-Scale Calculus Approach To Controlling The Impact Of West Nile Virus, Diana Thomas, Marion Weedermann, Lora Billings, Joan Hoffacker, Robert Washington-Allen Jan 2009

When To Spray: A Time-Scale Calculus Approach To Controlling The Impact Of West Nile Virus, Diana Thomas, Marion Weedermann, Lora Billings, Joan Hoffacker, Robert Washington-Allen

Department of Mathematics Faculty Scholarship and Creative Works

West Nile Virus (WNV) made its initial appearance in the New York City (NYC) metropolitan area in 1999 and was implicated in cases of human encephalitis and the extensive mortality in crows (Corvus sp.) and other avian species. Mosquitoes were found to be the primary vectors and NYC’s current policy on control strategies involved an eradication program that depends on the synchronicity of the summer mosquito population’s increases with the occurrence of cases in humans. The purpose of this paper is to investigate whether this is the most effective control strategy because past mathematical models assumed discrete behavior that …

An Evaluation Of Lead Hazards In Pre-1978 Residental Housing Within Clark County, Nevada, Usa, Erika Raquel Torres Jan 2009

An Evaluation Of Lead Hazards In Pre-1978 Residental Housing Within Clark County, Nevada, Usa, Erika Raquel Torres

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead poisoning remains a public health concern due to leads persistence in the environment from anthropogenic uses. Initial efforts to address the impacts of lead on vulnerable communities have included secondary prevention measures which typically occur after a child has been poisoned. However, in recent years there has been a pragmatic shift toward primary prevention efforts.

This study evaluates lead hazards identified through primary prevention activities in residential housing within Clark County, Nevada, USA. It is the first study to systematically address and evaluate pre-1978 housing in Southern Nevada. Risk assessments were conducted in 81 dwellings built prior to 1979 …

A Small Sample Correction For Estimating Attributable Risk In Case-Control Studies, Daniel B. Rubin Dec 2008

A Small Sample Correction For Estimating Attributable Risk In Case-Control Studies, Daniel B. Rubin

U.C. Berkeley Division of Biostatistics Working Paper Series

The attributable risk, often called the population attributable risk, is in many epidemiological contexts a more relevant measure of exposure-disease association than the excess risk, relative risk, or odds ratio. When estimating attributable risk with case-control data and a rare disease, we present a simple correction to the standard approach making it essentially unbiased, and also less noisy. As with analogous corrections given in Jewell (1986) for other measures of association, the adjustment often won't make a substantial difference unless the sample size is very small or point estimates are desired within fine strata, but we discuss the possible utility …

Theses and Dissertations

Background: Schizophrenia is a chronic, debilitating mental disorder characterized by positive (e.g., hallucinations, delusions) and negative (e.g., catatonia, flat affect) signs and symptoms. Many studies suggest that individuals born in winter or spring months are at increased risk for schizophrenia. Study Objectives: 1) To determine whether season of birth affects risk for schizophrenia in the Irish Study of High Density Schizophrenia Families (ISHDSF). 2) To examine, by computer simulation, power to detect genetic associations with schizophrenia under a variety of conditions and using different analytic strategies. 3) To test whether specific genes are associated with schizophrenia in the Irish Case …


Fetal And Early Neonatal Death: Do The Determinants Vary?, Ashley Carter Dec 2008

Fetal And Early Neonatal Death: Do The Determinants Vary?, Ashley Carter

Theses and Dissertations

Purpose: To compare the determinants and distribution of fetal and early neonatal deaths in the Commonwealth of Virginia. Background: Much attention is devoted to reducing the infant mortality rate which was declining up until 2002. The recent rise was parsed and found to stem from an increase in deaths during the early neonatal period. Fetal deaths are not well understood and are not routinely included when evaluating infant mortality. Methods: Using data collected from 2001 to 2006 fetal death and linked infant birth and death certificates by the Virginia Department of Health, crude mortality rates and leading causes of death …
