Public and Community Health Sciences Faculty Publications

Indoor and ambient concentrations of 21 Volatile Organic Compounds (including 14 Hazardous Air Pollutants) were measured in the homes of nearly 80 western Montana (Missoula) high school students as part of the ‘Air Toxics Under the Big Sky’ program during the 2004/2005 and 2005/2006 school years. Target analytes were measured using low flow air sampling pumps and sorbent tubes, with analysis of the exposed samples by Thermal Desorption/Gas Chromatography/Mass Spectrometry (TD/GC/MS). The results reported here present the findings of the first indoor/ambient air toxics monitoring program conducted in a semi-rural valley location located in the Northern Rocky Mountain/western Montana region. …

Community Woodstove Changeout And Impact On Ambient Concentrations Of Polycyclic Aromatic Hydrocarbons And Phenolics, Tony J. Ward, Christopher P. Palmer, James E. Houck, William C. Navidi, Steve Geinitz, Curtis W. Noonan

Public and Community Health Sciences Faculty Publications

A large woodstove changeout program was carried out in Libby, Montana, with the goal of reducing ambient levels of PM_2.5. This provided researchers the opportunity to measure ambient concentrations of phenolic and polycyclic aromatic hydrocarbons (PAHs) before, during, and after the changeout of nearly 1200 stoves to evaluate the effectiveness of the intervention. Starting in the heating season of 2004/2005 and ending in the heating season of 2007/2008, 19 compounds were measured every three days using a high-volume polyurethane foam (PUF) sampler followed by gas chromatography and mass spectrometry analysis. Some of the organic species with the highest …

Timeline Follow-Back Versus Global Self-Reports Of Tobacco Smoking: A Comparison Of Findings With Non-Daily Smokers, Kari J. Harris, Amanda L. Golbeck, Nikole J. Cronk, Delwyn Catley, Kathrene Conway, Karen B. Williams

Public and Community Health Sciences Faculty Publications

Methods assessing non-daily smoking are of concern because biochemical measures can not verify self-reports beyond 7 days. This study compares two self-reported smoking measures for non-daily smokers. A total of 389 college students, (48% female, 96% white, mean age of 19) smoking between 1 and 29 days out of the past 30, completed computer assessments in three cohorts with the order of administration of the measures counterbalanced. Values from the two measures were highly correlated. Comparisons of Timeline Follow-Back (TLFB) with the global questions for the total sample of non-daily smokers yielded statistically significant differences (p<.001), albeit small, between measures with the TLFB resulting on average in 2.38 more total cigarettes smoked out of the past 30 days, 0.46 less smoking days, and 0.21 more cigarettes smoked per day. Analyses by level of smoking showed that the discordance between the measures differed by frequency of smoking. Global questions of days smoked resulted in frequent reporting in multiples of five days, suggesting digit bias. Overall the two measures of smoking were highly correlated and equally effective for identifying any smoking in a 30-day period among non-daily smokers.

Profile Of Rural Health Insurance Coverage: A Chartbook, Jennifer D. Lenardson Mhs, Erika C. Ziller Phd, Andrew F. Coburn Phd

Access / Insurance

More than twenty years of research has demonstrated that rural residents are at greater risk of being uninsured compared to urban residents and more recent studies point to problems of underinsurance as well. Most studies have shown that the problems of uninsurance and underinsurance are greatest among rural residents living in smaller communities located further from more urbanized areas. Section I examines recent estimates and changes since 1997 in rural health insurance coverage. Section II explores differences in the demographic, socio-economic, employment and other risk factors for uninsurance among rural and urban residents. Section III profiles the demographic and economic …

Weathering The Storm: Climate Change, Vulnerability, And Adaptation In Bangladesh, Justin Guay

Electronic Theses and Dissertations

The world is guaranteed a certain level of climate change due to the emissions already released into the atmosphere. Therefore, adaptation to climate change is necessary. Increases in diarrheal disease and malnutrition due to climate change are analyzed for Bangladesh. Relative risks determined by the World Health Organization, estimates obtained from agricultural models, and migration estimates are utilized to determine the costs associated with each of these diseases, as well as reductions in rice production and increases in urban migration. It is found that climate change will create additional costs for treating each of these diseases that equal .05% of …

The Determinants Of First Nation And Inuit Health: A Critical Population Health Approach, Chantelle A.M. Richmond, Nancy A. Ross

Aboriginal Policy Research Consortium International (APRCi)

Environmental dispossession disproportionately affects the health of Canada’s Aboriginal population, yet little is known about how its effects are sustained over time. We use a critical population health approach to explore the determinants of health in rural and remote First Nation and Inuit communities, and to conceptualize the pathways by which environmental dispossession affects these health determinants. We draw from narrative analysis of interviews with 26 Community Health Representa- tives (CHRs) from First Nation and Inuit communities across Canada. CHRs identified six health determinants: balance, life control, education, material resources, social resources, and environmental/ cultural connections. CHRs articulated the role …

Modeling And Analysis Of The Spread Of Japanese Encephalitis With Environmental Effects, Ram Naresh, Surabhi Pandey

Applications and Applied Mathematics: An International Journal (AAM)

A nonlinear mathematical model for the spread of Japanese Encephalitis, caused by infected mosquito feeding on susceptible human population incorporating demographic and environmental factors is proposed and analyzed. In the modeling process, it is assumed that the growth rates of reservoir animal population and vector mosquito population are enhanced due to environmental discharges caused by human population related factors. The model is analyzed by stability theory of differential equations and computer simulation. Both the disease-free and the endemic equilibria are found and their stability is investigated. It is found that whenever the disease-free equilibrium is locally asymptotically stable, the endemic …

Detecting, Preventing, And Treating Sexually Transmitted Diseases Among Adolescent Arrestees: An Unmet Public Health Need, Steven Belenko, Richard Dembo, Matthew Rollie, Kristina Childs, Christopher Salvatore

Department of Justice Studies Faculty Scholarship and Creative Works

Studies of detained and incarcerated adolescent offenders in the United States indicate that these juveniles have an elevated risk of sexually transmitted diseases (STDs). However, many more arrestees enter the “front end” of the juvenile justice system that is detained or incarcerated, and research into the STD risk profiles and service needs of this larger group is lacking. An expansion of STD testing (including of asymptomatic youths), prevention, and treatment is needed, as is improved knowledge about gender- and race-specific services. A pilot program in Florida has shown that juvenile justice and public health systems can collaborate to implement STD …

Vitamin D has been associated with decreased risk of several cancers. In experimental studies, vitamin D has been shown to inhibit cell proliferation and induce differentiation and apoptosis in normal and malignant breast cells. Using a population-based case-control study on Long Island, New York, we examined the association of breast cancer with plasma 25-hydroxyvitamin D (25-OHD) levels, a measure of vitamin D body stores. In-person interviews and blood specimens were obtained from 1,026 incident breast cancer cases diagnosed in 1996 to 1997 and 1,075 population-based controls. Plasma 25-OHD was measured in batched, archived specimens by Diasorin RIA. The mean (SD) …

Faculty Publications

Background - Comparisons of incidence and mortality rates are the metrics used most commonly to define cancer-related racial disparities. In the US, and particularly in South Carolina, these largely disfavor African Americans (AAs). Computed from readily available data sources, the mortality-to-incidence rate ratio (MIR) provides a population-based indicator of survival.

Methods - South Carolina Central Cancer Registry incidence data and Vital Registry death data were used to construct MIRs. ArcGIS 9.2 mapping software was used to map cancer MIRs by sex and race for 8 Health Regions within South Carolina for all cancers combined and for breast, cervical, colorectal, lung, …

Can We Apply The Mendelian Randomization Methodology Without Considering Epigenetic Effects?, Ikechkwu U. Ogbuanu, Hongmei Zhang, Wilfried J. Karmaus

Faculty Publications

Introduction: Instrumental variable (IV) methods have been used in econometrics for several decades now, but have only recently been introduced into the epidemiologic research frameworks. Similarly, Mendelian randomization studies, which use the IV methodology for analysis and inference in epidemiology, were introduced into the epidemiologist's toolbox only in the last decade.

Analysis: Mendelian randomization studies using instrumental variables (IVs) have the potential to avoid some of the limitations of observational epidemiology (confounding, reverse causality, regression dilution bias) for making causal inferences. Certain limitations of randomized controlled trials, such as problems with generalizability, feasibility and ethics for some exposures, and high …

To Vaccinate, Or Not? Health Care Providers And The Hpv Controversy, Nicole Elizabeth Hanbury

Honors Scholar Theses

Gardasil® – the vaccine was first thought to be a medical breakthrough in the fight against cancer, but it quickly became plagued with controversy. Despite wide media coverage, little attention has been paid to today’s health care professionals who are ultimately responsible for prescribing the vaccine, and who may be the most knowledgeable about it. The present study seeks to expand on previous literature by investigating health care providers’ current beliefs and practices with the human papillomavirus (HPV) immunization. It is essential that more recent research be performed in order to encompass current views of the vaccine, post FDA-approval.
