Food Insecurity And Risky Sexual Behaviors Among College Students During The Covid-19 Pandemic, Bertille Assoumou, Jennifer Pharr, Courtney Coughenour

Environmental & Occupational Health Faculty Publications

Background

Sexually transmitted infections (STIs) and food insecurity are public health concerns in the United States (US) due to their growing prevalence and incidence among young people, and particularly in college students. Studies have reported that college students are at higher risk of STIs due to the high rates of risky sexual behavior (RSB). Most studies report a food insecurity prevalence of more than 30% among college students, which was more than twice the overall national food insecurity rate of 10.5% in 2020. This study aims to assess the relationship between food insecurity and RSB among college students during the …

Air Quality Health Benefits Of The Nevada Renewable Portfolio Standard, Alireza Rezaee, Lung-Wen Chen, Ge Lin, Mark P. Buttner, Max Gakh, Emma Frances Bloomfield

Environmental & Occupational Health Faculty Publications

In recent years, renewable portfolio standards (RPS), which require a certain percentage of electricity sold to consumers to come from renewable resources, have been established by many state governments to mitigate emissions of greenhouse gases and air pollutants in the United States. Nevada’s RPS set a target of 50% of electricity to come from renewable sources by 2030. By coupling the U.S. Environmental Protection Agency’s AVoided Emissions and geneRation Tool (AVERT) and CO–Benefits Risk Assessment (COBRA) model, this study assesses potential emission reductions from fossil fuels owing to this requirement and regional health benefits via improved air quality, as well …

China is a major player in the World Economy.

Environmentally Marginalized Populations: The "Perfect Storm" For Infectious Disease Pandemics, Including Covid-19, Gabriella Y. Meltzer, Oyemwenosa Avenbuan, Christina Awada, Oluwakemi B. Oyetade, Tricia Blackman, Simona Kwon Drph, Mph, Esther Erdei Phd, Judith T. Zelikoff Phd

Journal of Health Disparities Research and Practice

COVID-19 has exacted a severe toll on the United States population’s physical and mental health and its effects have been felt most severely among people of color and low socioeconomic status. Using illustrative case studies, this commentary argues that in addition to COVID-19 health disparities created by psychosocial stressors such as the inability to socially distance and access quality healthcare, environmental justice communities have the additional burden of disproportionate exposure to toxic contaminants that contribute to their higher risk of COVID-19. Environmental contaminants including heavy metals and persistent organic pollutants found contaminating their nearby environments can alter the immune response, …

Socio-Ecological Wellness Wheel: Applied To Community Gardens To Measure Green Gentrification, Micajah Daniels, Courtney Coughenour

McNair Poster Presentations

This project is intended to use Black Feminist Health Studies as an interdisciplinary approach to analyze the holisitc impacts of community gardens on nutrition behaviors. The implementation of green spaces such as community gardens have been correlated to both benefits and unintended consequences which this study demonstrates through the Socio-Ecological Wellness Wheel. An empirical and systematic way of measuring garden quality through an audit tool using Black Feminist Health Studies could help measure the nutrition environment of the community gardens and how they may influence fruit and vegetable consumption of food insecure populations. The need for this study is highlighted …

The Environmental Impact And Formation Of Meals From The Pilot Year Of A Las Vegas Convention Food Rescue Program, Samantha To, Courtney Coughenour, Jennifer Pharr

Environmental & Occupational Health Faculty Publications

Annually, millions of tonnes of leftover edible foods are sent to landfill. Not only does this harm the environment by increasing the release of greenhouse gases which contribute to climate change, but it poses a question of ethics given that nearly 16 million households are food insecure in the US, and hundreds of millions of people around the globe. The purpose of this study was to document the amount of food diverted from landfill in the pilot year of a convention food rescue program and to determine the amount of greenhouse gas (GHG) emissions avoided by the diversion of such …

Two-Stage Bagging Pruning For Reducing The Ensemble Size And Improving The Classification Performance, Hua Zhang, Yujie Song, Bo Jiang, Bi Chen, Guogen Shan

Environmental & Occupational Health Faculty Publications

Ensemble methods, such as the traditional bagging algorithm, can usually improve the performance of a single classifier. However, they usually require large storage space as well as relatively time-consuming predictions. Many approaches were developed to reduce the ensemble size and improve the classification performance by pruning the traditional bagging algorithms. In this article, we proposed a two-stage strategy to prune the traditional bagging algorithm by combining two simple approaches: accuracy-based pruning (AP) and distance-based pruning (DP). These two methods, as well as their two combinations, “AP+DP” and “DP+AP” as the two-stage pruning strategy, were all examined. Comparing with the single …

Healthy Food Options At Dollar Discount Stores Are Equivalent In Quality And Lower In Price Compared To Grocery Stores: An Examination In Las Vegas, Nv, Courtney Coughenour, Timothy J. Bungum, M. Nikki Regalado

Public Health Faculty Publications

Food deserts indicate limited access to and affordability of healthy foods. One potential mediator is the availability of healthy food in non-traditional outlets such as dollar-discount stores, stores selling produce at the fixed $1 price. The purpose of this study was to compare availability, quality, price differences in ‘healthier’ versus ‘regular’ food choices, price per each food item, and summary score in dollar-discount stores to grocery stores in Las Vegas using the NEMS-S; a protocol consisting of three subscores—availability, quality, price of healthier versus regular food, and a summary score.

Association Between Childhood Demographics And Blood Lead Screening---Nevada Kindergarten Health Survey 2010, Lina Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead, as a toxic substance, invades the human body, and gradually damages the organs. Oftentimes, elevated blood lead levels are not recognized until serious health issues are found. In the United States, approximately 250,000 children aged 1-5 years have elevated blood lead levels greater than 10 micrograms of lead per deciliter of blood (Centers for Disease Control and Prevention, 2004).

However, there is no effective treatment for lead poisoning. Chelation can merely decrease the blood lead levels but cannot reverse the existing damage. To prevent and control childhood lead poisoning, many studies have been conducted to investigate the sources of …

A Comparative Study Of Indicator Bacteria Present In Ice And Soda From Las Vegas Food Establishments, Kimberly Jo Hertin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Microbial analysis has long been used as an indicator of water quality. Since the passing of the Safe Drinking Water Act in 1974, microbial standards have been strictly set by the Environmental Protection Agency (EPA) to ensure that the public health is protected from bacterial pathogens. The bacteriological quality of water generally deteriorates as it travels from water treatment facilities through the main distribution system and into private plumbing and distribution systems. For example, Heterotrophic Plate Count (HPC) values typically increase once the water has entered plumbing devices such as beverage vending machines. Upon reaching a private facility, the opportunity …
