A Mixed-Methods Assessment of Residential Housing Tenants' Concerns about Property Habitability and the Implementation of Habitability Laws in Southern Nevada.

Housing is a key health determinant. Habitability laws set minimum standards for adequate housing. However, accessing them to ensure adequate housing may be a challenge for many tenants. This paper explores the need for rental housing policy that would better support adequate and safe housing, particularly for low-income renters. A mixed-methods approach assessed residential tenant habitability concerns in Clark County, Nevada, through calls relayed to the Clark County Landlord-Tenant Hotline (CCLTH). Of the 2865 calls, 74.3% were from ZIP codes that were 80% of the median income and below. There was a significant relationship between the ZIP code-level income and the reporting of at least one essential habitability concern. Of the 266 participants that responded to a follow-up call, 34.6% reported that their complaint was resolved and there was no association between resolution and income. Qualitative data analysis from phone interviews revealed two central themes: (1) resources to navigate landlord-tenant laws are limiting and (2) housing policies need to be strengthened to help tenants and keep people housed. Understanding tenant concerns regarding substandard housing and related inequities can help inform rental housing policy and its implementation to promote healthy homes and improve health outcomes for communities burdened by poor rental housing conditions.

Where I live: A qualitative analysis of renters living in poor housing.

This article examines the lived experiences of 17 renters residing in Clark County, Nevada. Using a phenomenological study design, we used semistructured interviews to investigate how renters navigate living in substandard housing. The qualitative analysis revealed four main themes: (a) housing serves as a mediator with one's sense of well-being and good health, (b) housing insecurity and displacement occur through various pathways, (c) housing quality can lead to a sense of powerlessness over where one lives, and (d) social networks are key in low-opportunity neighborhoods. The findings support numerous studies that connect housing quality and insecurity to health and well-being, but the findings also highlight the mediating factors to limited housing choices such as the landlord and tenant relationship. Studies of this nature are essential in identifying the various pathways by which housing inequities and disparities can occur, particularly among low-income communities.

Health Hazards in the Home: An Assessment of a Southern Nevada Community.

As a sub-grantee of a Department of Housing and Urban Development (HUD) Lead Hazard Control and Healthy Homes Program, the University of Nevada, Las Vegas' Department of Environmental and Occupational Health performed lead and Healthy Homes investigations and collected data regarding conditions in the home environment in Henderson, Nevada. The purpose of this research is to characterize housing conditions in southern Nevada, compare data to census data, and to highlight the health outcomes associated with adverse housing conditions. Visual home assessments were conducted in 106 homes in southern Nevada, and specific hazards were characterized using the Healthy Homes Rating System. The results were then compared, when possible, to American Housing Survey (AHS) data for the Las Vegas metropolitan area. Lead, domestic hygiene, carbon monoxide, damp and mold, excess cold and heat, and structural collapse were the most frequently identified hazards, found in at least 101 (90%) of participant households. Median household income of program participants was half (50%) that of the surrounding zip code, which was expected, as classification as "low-income" by HUD standards was a requirement for participation. Our data indicated that the AHS data may not be representative of very low income housing in southern Nevada and may underreport actual conditions. In-home inspections performed by trained personnel provide a more accurate picture of conditions than the self-report method used by the AHS. In addition, we recommend the development of a standardized Healthy Homes visual assessment tool to allow for the comparison of housing conditions between communities.

Implications of the new Centers for Disease Control and Prevention blood lead reference value.

The Centers for Disease Control and Prevention recently established a new reference value (≥ 5 µg/dL) as the standard for identifying children with elevated blood lead levels (EBLs). At present, 535,000 US children aged 1 to 5 years (2.6%) are estimated to have EBLs according to the new standard, versus 0.8% according to the previous standard (≥ 10 µg/dL). Because EBLs signify the threshold for public health intervention, this new definition increases demands on lead poisoning prevention efforts. Primary prevention has been proven to reduce lead poisoning cases and is also cost effective; however, federal budget cuts threaten the existence of such programs. Protection for the highest-risk children necessitates a reinstatement of federal funding to previous levels.

An evaluation of lead concentrations in imported hot sauces.

In the last decade, the U.S. Food and Drug Administration (FDA) has issued several warnings and recalls for food products that exceed FDA standards for lead. Products containing chili peppers and salt were often suspected as sources of lead contamination, and included items such as candy that are routinely investigated. However, products such as hot sauces that contain similar ingredients have not been the focus of evaluations. This study quantified lead concentrations in imported hot sauces, evaluated product compliance to existing United States standards, and calculated potential dietary lead exposure for children using the Integrated Exposure Uptake Biokinetic Model. Finally, recommendations for reducing the risk of lead exposure from hot sauces are provided. Twenty-five (25) bottles of imported hot sauces manufactured in Mexico and South America were purchased in Clark County, Nevada. All hot sauces were analyzed for lead concentrations, pH, and leaded packaging. Hot sauces were analyzed by inductively coupled plasma mass spectrometry and packaging was analyzed using x-ray fluorescence technology. Four brands of hot sauces (16%) exceeded 0.1 ppm lead, the current FDA action level for lead in candy. Hot sauces with lead concentrations >0.1 ppm lead contained salt and were manufactured in Mexico. Subsequent analysis of additional lots of hot sauces exceeding 0.1 ppm lead revealed inconsistent lead concentrations between and within manufacturer lots. The lead concentrations of the plastic hot sauce lids ranged from below the limit of detection to 2,028 ppm lead. There was no association between lead concentrations in hot sauces and pepper type. These results indicate the need for more rigorous screening protocols for products imported from Mexico, the establishment of an applicable standard for hot sauce, and resources to allow for the enforcement of existing food safety policies. The data reported herein represent the first known investigation of lead concentrations in hot sauces.

High-risk human papillomavirus (HPV) screening and detection in healthy patient saliva samples: a pilot study.

BACKGROUND: The human papillomaviruses (HPV) are a large family of non-enveloped DNA viruses, mainly associated with cervical cancers. Recent epidemiologic evidence has suggested that HPV may be an independent risk factor for oropharyngeal cancers. Evidence now suggests HPV may modulate the malignancy process in some tobacco- and alcohol-induced oropharynx tumors, but might also be the primary oncogenic factor for inducing carcinogenesis among some non-smokers. More evidence, however, is needed regarding oral HPV prevalence among healthy adults to estimate risk. The goal of this study was to perform an HPV screening of normal healthy adults to assess oral HPV prevalence. METHODS: Healthy adult patients at a US dental school were selected to participate in this pilot study. DNA was isolated from saliva samples and screened for high-risk HPV strains HPV16 and HPV18 and further processed using qPCR for quantification and to confirm analytical sensitivity and specificity. RESULTS: Chi-square analysis revealed the patient sample was representative of the general clinic population with respect to gender, race and age (p < 0.05). Four patient samples were found to harbor HPV16 DNA, representing 2.6% of the total (n = 151). Three of the four HPV16-positive samples were from patients under 65 years of age and all four were female and Hispanic (non-White). No samples tested positive for HPV18. CONCLUSIONS: The successful recruitment and screening of healthy adult patients revealed HPV16, but not HPV18, was present in a small subset. These results provide new information about oral HPV status, which may help to contextualize results from other studies that demonstrate oral cancer rates have risen in the US among both females and minorities and in some geographic areas that are not solely explained by rates of tobacco and alcohol use. The results of this study may be of significant value to further our understanding of oral health and disease risk, as well as to help design future studies exploring the role of other factors that influence oral HPV exposure, as well as the short- and long-term consequences of oral HPV infection.
