Journal of Health Disparities Research and Practice

ABSTRACT

This study attempts to clarify the associations between macro-social and social network factors and continuing racial disparities in breast cancer survival. The study improves on prior methodologies by using a neighborhood disadvantage measure that assesses both economic and social disadvantage and an ego-network measurement tool that assesses key social network characteristics. Our population-based sample included 786 breast cancer patients (nHWhite=388; nHBlack=398) diagnosed during 2005-2008 in Chicago, IL. The data included census-derived macro-social context, self-reported social network, self-reported demographic and medically abstracted health measures. Mortality data from the National Death Index (NDI) were used to determine 5-year survival.

Exploring H.Pylori Seropositivity As A Risk Factor For Type 2 Diabetes, Virginia Chaidez, Yumou Qiu

Journal of Health Disparities Research and Practice

Background: In the US, the percentage of adults with diagnosed diabetes are higher in members of racial and ethnic minority groups compared to non-Latino Whites. Understanding why such disparities exist has been less forthcoming.

Methods: Secondary data analysis was conducted using the National Health and Nutrition Examination Survey (NHANES) 1999-2000 cross-sectional data.

Results: H.pylori seropositivity was highest in Mexican Americans (43.7%), lowest in non-Hispanic Whites (18.1%). Diabetes was highest in non-Hispanic Blacks (5.9%); lowest in non-Hispanic whites (4.3%). H.pylori seropositivity was associated with greater likelihood of having type 2 diabetes (1.927, 95% CI 1.142, 3.257) compared to H.pylori negative in …

Journal of Health Disparities Research and Practice

Human papillomavirus (HPV) infection is the most common sexually transmitted infection worldwide and has been linked to several cancers, including cervical cancer. In the United States, the Southern region has a disproportionate burden of cervical cancer, and research about the epidemiology of HPV in the region is scarce. This study estimates the prevalence and correlates of HPV infection among 14–59 year-old females.

Data from 4,250 females aged 14–59 years collected during the 2007–2010 National Health and Nutrition Examination Survey (NHANES) were used. We estimated the prevalence of HPV infection for the South and the rest of the country. We performed …

Prostate Cancer Survival Among Hispanics: A Surveillance, Epidemiology, And End Results (Seer) Population-Based Cohort Study, David Rivas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Hispanics are now the youngest, largest, and fastest growing minority group in the U.S. Prostate cancer (PC) is the most commonly diagnosed cancer in men and is the second-leading cause of cancer deaths among Hispanics. For the first time, we examined PC-specific survival among distinct Hispanic groups that include Mexicans, Cubans, Dominicans, Puerto Ricans, as well as Central and South Americans. We compared these groups to the main reference population in the U.S., non-Hispanic Whites (NHW), after adjustment for prognostic factor risk categories (prostate-specific antigen (PSA) level, Gleason score, and tumor stage), as well as sociodemographic covariates (e.g., health insurance, …

Graduating Into Lower Risk: Chlamydia And Trichomonas Prevalance Among Community College Students And Graduates, Janet E. Rosenbaum

Journal of Health Disparities Research and Practice

Background: Community colleges enable youth from economically disadvantaged and minority populations to access college and may enable social mobility including improved health outcomes. However, educational health disparities studies rarely assess the health outcomes for community college graduates.

Methods: Chlamydia and trichomonas prevalence were assessed with nucleic acid based tests in a nationally representative sample of 6233 high school graduates (ages 18–25) from five educational levels: young adults without post-secondary credentials who were not enrolled in college, community college students, 4-year college students, associate’s degree, and bachelor’s degree. To reduce confounding between educational attainment and STI status, we used full matching …

Method: We conducted a five-year (2010-2014) trends analysis using birth and infant death data extracted from the Florida Community Health Assessment Resource Tool Set (CHARTS). The number of infant deaths and live births were used to calculate and compare IMRs in the CHHS catchment area to those …

Race And “Hotspots” Of Preventable Hospitalizations, Caryn N. Bell, Janice V. Bowie, Roland J. Thorpe Jr.

Journal of Health Disparities Research and Practice

Abstract

Preventable hospitalizations (PHs) are those for ambulatory care-sensitive conditions that indicate insufficiencies in local primary healthcare. PH rates tend to be higher among African Americans, in urban centers, rural areas and areas with more African American residents. The objective of this study is to determine geographic clusters of high PH rates (“spatial clusters”) by race. Data from Maryland hospitals were utilized to determine the rates of PHs in zip code tabulation areas (ZCTAs) by race in 2010. Geographic clusters of ZCTAs with higher than expected PH rates were identified using Scan Statistic and Anselin’s Local Moran’s I. 10 PH …

The Role Of Pre-Existing Type 2 Diabetes Mellitus In Colorectal Cancer Stage And Survival In Elderly Americans: A Seer-Medicare Population-Based Study 2002-~2011, Sanae El Ibrahimi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Diabetes is a common comorbid condition among colorectal cancer (CRC) patients, yet its effects in CRC outcomes, particularly stage at diagnosis, risk of death and variations by diabetes severity (complications vs no complications) and Hispanic ethnicity have not been adequately studied. The purpose of this study was to investigate the association between pre-existing T2DM and advanced stage at diagnosis in elderly patients with CRC; to examine whether diabetes is an independent predictor of poor survival from all-cause and CRC-specific mortality; to assess whether variations exist by diabetes severity and to analyze the outcomes for the Hispanic group.

The Impact Of Economic Recession On The Health Of Adult Nevadans, Ariana Goertz

UNLV Theses, Dissertations, Professional Papers, and Capstones

Recessions are generally considered to cause negative consequences, but recent studies have provided evidence that some health outcomes improve as the economy deteriorates. The relationship between economic downfalls and health is not straightforward; it is important to look at how health has been impacted in one of the areas hit hardest by the recession. Las Vegas, Nevada was previously considered recession-proof, seemingly unaffected by previous economic downturns exhibited by the rest of the country. However, during the Great Recession of 2007-2009, Las Vegas led the country in highest rates of unemployment and foreclosures. This was quite a collapse for a …

Residential Segregation, Neighborhood Social And Physical Context In Obesity Disparities In Hispanic Preschoolers: A Conceptual Model, Catherina Chang Martinez Phd(C), Nasar U. Ahmed Phd, Ruby A. Natale Phd, Psyd

Journal of Health Disparities Research and Practice

During the last decade, there has been a significant inclusion in obesity prevention studies from individual characteristics to household factors then neighborhood factors. The study of place in the context of early childhood obesity studies has been limited to the food and physical built environment. With the persistent disparities in the prevalence of childhood obesity, and Hispanic minorities being increasingly affected, there is a need to reexamine existing models and develop new model conceptual frameworks to examine the role of place and residential segregation in the context of race, ethnicity, social position, and socioeconomic disparities. In the context of place …

Determining The Effects Of Social Media Monitoring To Identify Potential Foodborne Illness In Southern Nevada, Lauren Diprete

UNLV Theses, Dissertations, Professional Papers, and Capstones

Foodborne illness, commonly referred to as food poisoning, affects an estimated 1 in 6 Americans every year, despite the fact that it is entirely preventable. Many cases of foodborne illness go unreported; however, better reporting leads to faster health department response and containment. Social media monitoring, using software to identify trends in social media posts, is a novel new tool that has been tested in a variety of public health fields with promising preliminary results. The Southern Nevada Health District (SNHD) has employed social media monitoring software to identify potential foodborne illness within Southern Nevada. The purpose of this study …

Does Educational Level Influence Postmenopausal Breast Cancer Mortality Among Asians In U.S.?, Sfurti Maheshwari

UNLV Theses, Dissertations, Professional Papers, and Capstones

Studies on mortality from postmenopausal breast cancer (PMBC) by education level have not shown consistent results among US women. For US Asians, often seen as a “model” minority in terms of affluence and education this relationship has never been studied despite PMBC being the most common cancer in the country.

We analyzed 2008-2012 California Vital Statistics data and population data from the American Community Survey 2012 to compute age and education adjusted mortality ratios using negative binomial regression model for White (as a reference category) and Asian women. In total 3,277,106 (80%) White women and 852,376 (20%) Asian women died …

Association Of Genetic Factors With Chronic Kidney Disease In Us Young Adults, Sabra Stanford

UNLV Theses, Dissertations, Professional Papers, and Capstones

Albumin, a protein that when found in urine, is an early indicator of Chronic Kidney Disease (CKD). Genetic contributions have been shown to illustrate the gene-environment interactions that may lead to CKD in an individual; however, few studies have highlighted the interaction between responses of gene variations associated with the risk of increased albumin in young adults. This study’s purpose is to evaluate the hypothesis that candidate genes are related to microalbuminuria in young adults of the third wave of the National Longitudinal Study of Adolescent Health (Add Health Wave III). This longitudinal study includes an assessment of various candidate …

Non-Hispanic Blacks and Mexican Americans …

Exploring Sexual And Behavioral Health Inequities Among College Students: A Need For Lgb-Specific Risk Reduction, Todd M. Sabato

Journal of Health Disparities Research and Practice

Many studies have examined differences in sexual behavior based upon self-identified sexual orientation, with results often indicating that those with same-sex partners engage in greater risk behaviors than those with opposite sex partners. However, few of those studies consisted of large, national sample studies. To address that gap, the present study examined the relationship between sexual orientation and both behavioral and sexual health outcomes in a national sample of U.S. college students. The Fall 2012 through Spring 2014 American College Health Association National College Health Assessment was used to examine behavioral and sexual health related responses from self-identified heterosexual, gay, …

Intra-Ethnic Diversity In Ischemic Heart Disease And Stroke Mortality Among Hispanics In The United States, Karen Elizabeth Callahan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Hispanics are the largest racial/ethnic minority group in the United States (US), comprising 17% of the total US population in 2014, and projected to increase to 28.6% by 2060. Yet, the intra-ethnic heterogeneity for the second and fourth leading causes of death among Hispanic populations, heart disease and stroke, has never been comprehensively studied. We examined ischemic heart disease (IHD) and stroke mortality among distinct Hispanic subgroups: Caribbean Hispanics (including Puerto Ricans, Cubans, and Dominicans), Mexicans, Central Americans and South Americans, comparing their mortality with non-Hispanic whites (NHWs).

Methods: Five years (2008-2012) of death certificate data from Florida and …

Self-Care And Mobility Disability At Mid-Life In Lucky Few, Early-, And Late-Baby Boom Birth-Cohorts, Carlos Siordia

Journal of Health Disparities Research and Practice

Disability is related in definite ways with makers of social stratum, as it can be influenced by and has the potential to contribute to the production and reproduction of social stratification. Intersectional markers of social stratification processes are ignored determinants of health. The Class, Race, Sex (CRS) hypothesis presented here argues that a low-education, racial-minority, and female disadvantage will compound to affect the prevalence and risks of disability. The evidence presented validates the CRS hypothesis by showing that disability prevalence and risk clusters first by class, race, and then sex. The cross-sectional study of community-dwelling adults in the Unites States, …

Monitoring Gambling Impacts In Massachusetts: Honing Strategies And Preventing Harm, Rachel A. Volberg, Amanda Houpt

International Conference on Gambling & Risk Taking

In November 2011, an Act Establishing Expanded Gaming in the Commonwealth of Massachusetts was signed into law (Chapter 194 of the Acts of 2011). This legislation permits casinos and slot parlors in Massachusetts under the regulatory auspices of the Massachusetts Gaming Commission (MGC). Section 71 of the Expanded Gaming Act requires the MGC to establish an annual research agenda to assist in understanding the effects of casino gambling in Massachusetts and in minimizing the negative impacts.

A Public Health-Based Approach To German Gaming Regulation, Knut Walter, Gerhard Buehringer

International Conference on Gambling & Risk Taking

The current situation of the German gambling market can be characterized by an unrelated framework of different legal systems, different regulatory authorities and different control principles, and has led to (1) an increasing number of court decisions and information requests by European Commission questioning parts of that regulatory system, (2) public tolerance of illicit gambling, and consequently (3) a lack of consumer protection.

Taking RENO Model 1.0 and 2.0 seriously, a new and comprehensive regulatory framework based on common consumer protection standards for all types of gambling – land-based and online, state-owned and private operated – has been developed and …

Differences In Perceived Importance Of Preventative Services And Healthcare Provider Trust Among Hispanics, Jonathan James Gore

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Hispanic population varies greatly in their risk factors, health outcomes and access to care by country of origin, level of education and language dominance (Vega & Amaro, 1994) (Fiscella, Franks, Doescher, & Saver, 2002b). The differences within the Hispanic population also extend to their knowledge and attitudes toward health choices and maintenance, where they receive their health information, and what they access to meet their health care needs. Subpopulations within the Hispanic community as defined by language dominance and nativity must be understood as separate and distinct so that the health needs of each can be adequately addressed. The …

Cancer Among Asian American Population In The United States: Incidence And Survival Disparities, Hongbin Jin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Part I

Cancer incidence disparities exist among specific Asian American populations. However, the existing reports exclude data from large metropoles like Chicago, Houston, and New York. Moreover, incidence rates by subgroup have been underestimated due to the exclusion of Asians with unknown subgroup. Cancer incidence data for 2009 to 2011 for eight states accounting for 68% of the Asian American population were analyzed. Race for cases with unknown subgroup was imputed using stratified proportion models by sex, age, cancer site, and geographic regions. Age-standardized incidence rates were calculated for 17 cancer sites for the six largest Asian subgroups. Our analysis …
