Meeting Physical Activity Guidelines And Health Outcomes In The Elderly: Are Racial Differences Important?, R. Michael Johnson 2017 Wright State University - Main Campus

Meeting Physical Activity Guidelines And Health Outcomes In The Elderly: Are Racial Differences Important?, R. Michael Johnson

Michael C. Johnson

Physical activity guidelines for health improvement were recommended by the Centers for Disease Control and Prevention (CDC) in 2008. Today, data on individuals’ adherence to the CDC guidelines are collected as part of its Behavioral Risk Factor Surveillance System (BFRSS) survey. While racial disparities in health outcomes are well documented, analyses of the BRFSS data have the potential to shed light on whether there are racial differences in the relationship between physical activity and health outcomes.

The 2015 (BRFSS) dataset contained responses from 441,456 individuals, including 42,516 over the age of 65 who had complete data on the ...


Using Ranked Auxiliary Covariate As A More Efficient Sampling Design For Ancova Model: Analysis Of A Psychological Intervention To Buttress Resilience, Rajai Jabrah, Hani Samawi, Robert Vogel, Haresh Rochani, Daniel Linder 2017 Georgia Southern University

Using Ranked Auxiliary Covariate As A More Efficient Sampling Design For Ancova Model: Analysis Of A Psychological Intervention To Buttress Resilience, Rajai Jabrah, Hani Samawi, Robert Vogel, Haresh Rochani, Daniel Linder

Robert L. Vogel

Drawing a sample can be costly or time consuming in some studies. However, it may be possible to rank the sampling units according to some baseline auxiliary covariates, which are easily obtainable, and/or cost efficient. Ranked set sampling (RSS) is a method to achieve this goal. In this paper, we propose a modified approach of the RSS method to allocate units into an experimental study that compares L groups. Computer simulation estimates the empirical nominal values and the empirical power values for the test procedure of comparing L different groups using modified RSS based on the regression approach in ...


The Determinants Of Strength Training In Rural Women, Ages 20-44 Years: A Qualitative Study, Dziyana Nazaruk, Stuart H. Tedders, Moya L. Alfonso, Robert Vogel 2017 Georgia Southern University

The Determinants Of Strength Training In Rural Women, Ages 20-44 Years: A Qualitative Study, Dziyana Nazaruk, Stuart H. Tedders, Moya L. Alfonso, Robert Vogel

Robert L. Vogel

Despite multiple health benefits of strength training, it is reported that only 14.7% of American women engage in the recommended amount of physical activity. Whereas the potential negative consequences of not exercising are well documented, there is a scarcity of literature that investigates the determinants of strength training in rural women. In-depth interviews were utilized to identify the perceptions, knowledge, motivation, and skills regarding strength training. Fifteen women from four target counties participated in this qualitative study. The study was guided by Self-determination Theory. Results indicated that factors such as the lack of knowledge about strength training, the lack ...

Evaluating The Efficiency Of Treatment Comparison In Crossover Design By Allocating Subjects Based On Ranked Auxiliary Variable, Yisong Huang, Hani Samawi, Robert Vogel, Jingjing Yin, Worlanyo E. Gato, Daniel Linder

Robert L. Vogel

The validity of statistical inference depends on proper randomization methods. However, even with proper randomization, we can have imbalanced with respect to important characteristics. In this paper, we introduce a method based on ranked auxiliary variables for treatment allocation in crossover designs using Latin squares models. We evaluate the improvement of the efficiency in treatment comparisons using the proposed method. Our simulation study reveals that our proposed method provides a more powerful test compared to simple randomization with the same sample size. The proposed method is illustrated by conducting an experiment to compare two different concentrations of titanium dioxide nanofiber ...

Correction Of Verification Bias By Application Of Homogeneous Log-Linear Models For A Single Scale Binary Diagnostic Test, Haresh D. Rochani, Hani M. Samawi, Robert L. Vogel, Jingjing Yin

Robert L. Vogel

In patient management and control of many infectious diseases it is very crucial to have accurate diagnostic test. The test/procedure that determines the true disease status without an error is referred to as gold standard test. Even when a gold standard exist, it is extremely difficult to verify each patient due to the issues of cost-effectiveness and invasive nature of the procedures. In practice some of the patients with test results are not selected for verification of the disease status which results into a verification bias for diagnostic tests. The ability of the diagnostic tests to correctly identify the ...


Persistent Organic Pollutants And Mortality In The United States, Nhanes 1999-2011., Kristiann Fry, Melinda C Power 2017 George Washington University

Persistent Organic Pollutants And Mortality In The United States, Nhanes 1999-2011., Kristiann Fry, Melinda C Power

Epidemiology and Biostatistics Faculty Publications

Background

Persistent organic pollutants (POPs) are environmentally and biologically persistent chemicals that include polybrominated diphenyl ethers (PBDEs), per- and polyfluoroalkyl substances (PFASs), polychlorinated biphenyls (PCBs), and organochlorine (OC) pesticides. Currently, data on the associations between exposure to POPs and the risk of mortality in the U.S. population is limited.

Our objective was to determine if higher exposure to POPs is associated with greater risk of all-cause, cancer, heart/cerebrovascular disease, or other-cause mortality.

Methods

Analyses included participants aged 60 years and older from the 1999–2006 National Health and Nutrition Examination Surveys (NHANES). We included 483 participants for analyses ...

Journal of Adolescent and Family Health

Researchers and youth stakeholders devised a survey on 27 adversities based on youth expertise, clinical practice, and adversity literature. The aim of the study was to understand the prevalence of individual and cumulative adversities, and association of adversities to age, gender, race/ethnicity and academic performance among a community sample of urban high school students. All participants experienced two or more adversities and experienced greater overall adversity than youth in population-based studies. Youth-proposed stressors were among the most prevalent, and females, older youth, and African American youth reported disproportionately greater number of adversities. Specific types of adversities were endorsed differentially ...


I Want An Omnipotent Doctor: North Korean Defectors’ Unmet Expectations Of South Korean Medical Providers, Soo Jung Hong 2017 Huntsman Cancer Institute - the University of Utah

I Want An Omnipotent Doctor: North Korean Defectors’ Unmet Expectations Of South Korean Medical Providers, Soo Jung Hong

The Qualitative Report

This study examines North Korean defectors’ unmet expectations of South Korean medical providers from the perspectives of both North Korean defectors and their medical providers. Seventeen defectors and 12 medical providers were recruited for focus groups and in-depth interviews. Grounded theory was used for data analysis. Data indicates the North Korean defectors were not satisfied with their providers because they (1) preferred human techniques over computerized technology, (2) expected the doctors to be omnipotent, and (3) expected to receive emergency medical service but did not expect to pay for it. Their medical providers felt that it was impossible to satisfy ...

Rickettsia philipii (type strain “Rickettsia 364D”), the etiologic agent of Pacific Coast tick fever (PCTF), is transmitted to people by the Pacific Coast tick, Dermacentor occidentalis. Following the first confirmed human case of PCTF in 2008, 13 additional human cases have been reported in California, more than half of which were pediatric cases. The most common features of PCTF are the presence of at least one necrotic lesion known as an eschar (100%), fever (85%), and headache (79%); four case-patients required hospitalization and four had multiple eschars. Findings presented here implicate the nymphal or larval stages of D. occidentalis as ...

Los Angeles and Orange Counties are known endemic areas for murine typhus in California; however, no recent reports of flea-borne rickettsioses are known from adjacent San Bernardino County. Sixty-five opossums (Didelphis virginiana) were trapped in the suburban residential and industrial zones of the southwestern part of San Bernardino County in 2007. Sixty out of 65 opossums were infested with fleas, primarily cat fleas, Ctenocephalides felis (Bouché, 1835). The flea minimum infection rate with Rickettsia felis was 13.3% in pooled samples and the prevalence was 23.7% in single fleas, with two gltA genotypes detected. In spite of historic records ...

Rickettsia felis is an emerging human pathogen associated primarily with the cat flea Ctenocephalides felis. In this study, we investigated the presence of Rickettsia felis in C. felis from Guatemala and Costa Rica. Ctenocephalides felis were collected directly from dogs and cats, and analyzed by polymerase chain reaction for Rickettsia-specific fragments of 17-kDa protein, OmpA, and citrate synthase genes. Rickettsia DNA was detected in 64% (55 of 86) and 58% (47 of 81) of flea pools in Guatemala and Costa Rica, respectively. Sequencing of gltA fragments identified R. felis genotype URRWXCal2 in samples from both countries, and genotype Rf2125 in ...
