A sample of 165 participants age 18 or older from 2 chiropractic clinics in the midwestern United States completed a Likert-scaled survey. The data were analyzed using descriptive statistics and multiple regression …


Association Between Vegan, Vegetarian, And Omnivorous Diets And Overweight And Obesity, Daniel Sullivan Jan 2011

Association Between Vegan, Vegetarian, And Omnivorous Diets And Overweight And Obesity, Daniel Sullivan

Walden Dissertations and Doctoral Studies

Overweight and obesity and associated health risks have become epidemic in several regions around the world. Numerous studies have addressed the dietary habits of vegetarians and vegans in terms of disease prevention and nutritional deficiencies but the relationship between overweight and obesity and the demographic, psychosocial, lifestyle, and dietary intake of omnivores, vegetarians, and vegans has received less attention. Guided by the social-ecological model, this study included a cross-sectional, quantitative, anonymous web-based survey to obtain dietary information on omnivores, vegetarians, and vegans. Vegans demonstrated a significantly lower mean and median body mass index ( p=0.00) than omnivores, semi-vegetarians, and vegetarians. …


Effects Of A Web-Based Decision Aid On African American Men's Prostate Screening Knowledge And Behavior, Beverly Layton Jan 2011

Effects Of A Web-Based Decision Aid On African American Men's Prostate Screening Knowledge And Behavior, Beverly Layton

Walden Dissertations and Doctoral Studies

African American men have the highest prostate cancer occurrence and deaths of any population, yet many are unaware of screening opportunities or prognoses if diagnosed with the disease. The focus of this study was to learn whether a web-based prostate health education decision aid would increase prostate cancer knowledge, declared intention to be screened, and the likelihood of scheduling a prostate-specific antigen (PSA) test. The transtheoretical model of behavior change served as the theoretical framework for the study to assess readiness to adopt new behaviors. A total of 128 African American men between the ages of 40--65 without a history …


Religious-Base Social Relationship And The Psychological Well-Being Of The Elderly: Gender And Race Variations, Eugene C. Uche Jan 2011

Religious-Base Social Relationship And The Psychological Well-Being Of The Elderly: Gender And Race Variations, Eugene C. Uche

Walden Dissertations and Doctoral Studies

More people in the United States are approaching retirement age, a trend which has resulted in increased study on life satisfaction and psychological well-being of the elderly. Previous researchers have focused on the relationship between religious social support and life satisfaction; however, there remains a gap in the literature regarding how race and gender may influence this association. Knowledge of interactions between religiosity, gender, and race will enable counselors working with different groups of religiously inclined clients to develop and implement religious-based interventions specific to their clients. Guided by the social ecological model, the purpose of this study was to …

This secondary analysis of a national convenience-based study examined screening compliance among 647 African American lesbian and bisexual women. Barriers to accessing screening represented the theoretical framework for this study. Bivariate chi square analysis was used to assess the association between independent variables: sociodemographic characteristics; participation in wellness activities; sexual orientation/gender …


Physician Decision Criteria Regarding Omega-3 Dietary Supplements, Warren P. Lesser Jan 2011

Physician Decision Criteria Regarding Omega-3 Dietary Supplements, Warren P. Lesser

Walden Dissertations and Doctoral Studies

American Heart Association officials and other expert cardiologists recommend omega-3 (n-3) dietary supplementation for the secondary prevention of cardiovascular disease, a prevalent health problem in the United States. Physicians' lack of understanding of possible n-3 preventive health benefits results in underprescribing n-3 dietary supplements and lower n-3 dietary supplement product sales. N-3 dietary supplement marketers do not understand physician n-3 prescribing decision criteria enough to optimize high-impact communication to physicians to increase n-3 dietary supplement product use. The purpose of this phenomenological research study was to improve n-3 marketers' understanding of how physicians reach decisions to prescribe or recommend products …

Leadership And Attitudes On Adopting Evidence-Based Practice For Influenza Vaccination, Pamela A. Paparone

Walden Dissertations and Doctoral Studies

The United States has set a 90% benchmark for influenza vaccinations for healthcare personnel. Unfortunately, healthcare personnel fall far short of that mark with current rates as low as 62%. Low vaccination rates are responsible for influenza, nosocomial influenza, influenza-like illness, and mortality during influenza season. The purpose of this quantitative correlational study was to understand the relationship between leadership styles, attitudes towards evidence-based practice, and vaccination intention among New Jersey registered nurses (RNs). Diffusion of innovations theory was the theoretical foundation. The 3 instruments used were the Multifactor Leadership Questionnaire, Evidence Based Practice Attitude Scale, and Behavioral Intention Scales, …

This study was based on social cognitive theory and tested hypothesized positive relations between HIV serostatus disclosure, social support, and self-efficacy. In addition, self-rated HIV stigma was examined as a potential mediating variable. Participants were 109 HIV positive, mostly White gay men recruited via an online bulletin board. They completed the medical outcomes study social support survey, the general self-efficacy scale, the …


Examining The Relationship Among Physical And Psychological Health, Parent And Peer Attachment, And Cyberbullying In Adolescents In Urban And Suburban Environments, Jemica Monique Carter Jan 2011

Examining The Relationship Among Physical And Psychological Health, Parent And Peer Attachment, And Cyberbullying In Adolescents In Urban And Suburban Environments, Jemica Monique Carter

Wayne State University Dissertations

Cyberbullying is a new phenomenon that has received substantial attention via media. An extensive review of the literature revealed limited nursing research on this topic. The purpose of this study was to examine the impact of cyberbullying on adolescents' physical (e.g., headache, stomachache, etc.) and psychosocial (e.g., self-esteem, depression, post traumatic stress syndrome, etc.) outcomes. Individuals who experience repeated traditional bullying are at increased risk for experiencing repeated incidents of cyberbullying. Research has shown that effects of cyberbullying may be more traumatic than traditional bullying because victims can be bullied 24 hours and 7 days a week, on and off …

Hiv Integrated Biological And Behavioural Surveillance Survey (Ibbss) 2010, Federal Ministry Of Health Jan 2011

Hiv Integrated Biological And Behavioural Surveillance Survey (Ibbss) 2010, Federal Ministry Of Health

HIV and AIDS

This report by the Nigerian Federal Ministry of Health highlights the findings of an integrated biological and behavioral surveillance survey (IBBSS) in Nigeria among groups whose behaviors or occupations often place them at higher risk of contracting sexually transmitted infections, including HIV. The main objectives of the study were to assess the knowledge and beliefs of high-risk groups about STI and HIV, determine the prevalence of HIV infection among these groups, and obtain data that will permit identification of trends over time. Since the 2007 IBBSS survey report, a considerable number of interventions have commenced among the study groups.

Prevalence Of Sexually Transmitted Infections Among Men Who Have Sex With Men And Injecting Drug Users And Validation Of Audio Computer-Assisted Self Interview (Acasi) Technique In Abuja, Lagos, And Ibadan, Nigeria: Technical Report, Enhancing Nigeria's Hiv/Aids Response (Enr) Programme

HIV and AIDS

Most-at-risk populations (MARPS), including men who have sex with men (MSM) and injecting drug users (IDUs), represent 1 percent of Nigeria’s population yet account for 38 percent of new HIV infections. Despite their elevated risk, MSM and IDUs are less likely than the general population to access HIV prevention and sexual health services because of stigmatization. There is a dearth of data on prevalence of HIV and sexually transmitted infections (STIs) among MSM and IDUs because their behaviors make them difficult to be reached programmatically and engaged in research. While the need for HIV and STI prevalence data is clear, …

Optimal Control Applied To A Discrete Time Influenza Model, Paula Andrea Gonzalez Parra Jan 2011

Optimal Control Applied To A Discrete Time Influenza Model, Paula Andrea Gonzalez Parra

Open Access Theses & Dissertations

For the last decades, mathematical epidemiological models have been used to understand the dynamics of infectious diseases and guide public health policy.

In particular, several continuous models have been considered to study influenza outbreaks and their controls policies. However, most epidemiological data is discrete; therefore, a discrete formulation is more convenient to compare collected data with the output of the model. We introduce a discrete time model in order to study optimal control strategies for influenza transmission.

In our model, we divide the population into four classes: susceptible, infectious, treated, and recovered individuals.

In particular, we evaluate the potential effect …
