A Comparative Study of Cervical Cancer Among Indigenous Amerindian, Afro-Guyanese, and Indo-Guyanese Women in Guyana

Jones-Williams, Carol 01 January 2017 (has links)
Cervical cancer is a major public health problem in developing countries. In Guyana, factors associated with increasing cervical cancer cases among Indigenous Amerindian women (IAW), Afro- women (AGW), and Indo-Guyanese women (IGW) have not been fully examined. In this comparative cross-sectional study, 5,800 cervical cancer cases were selected from Guyanese women age 13 and above for ethnicity (Indigenous Amerindian, Afro- and Indo Guyanese women), geographical region, marital status, and year and stage at diagnosis. Secondary data from Guyana Cancer Registry for the 2000-2012 study periods were analyzed using chi-square test, multinomial logistic regression, poisson regression, and relative risk. Geographical region was a strong predictor of cervical cancer cases for all three ethnic groups (p < 0.05). The relative risk for cervical cancer for IAW in Regions 2 (RR = 1.2) and 6 (RR = 1.07) was greater than for IAW in Region 4, the reference group for the study period. Comparatively, the relative risk for cervical cancer for AGW in Region 4 was greater than AGW in all other regions except Region 3 (RR = 1.05). Additionally, the relative risk for cervical cancer for IGW in Region 3 (RR = 1.03) was greater than that of IGW in all other regions. Single IAW (1.05) have a higher risk of getting cervical cancer than their married counterparts as compared to AGW (0.96) and IGW (1.00). Implications for social change include development of tailored programs which utilize a socio-ecological model to address cervical cancer issues at the individual, interpersonal, cultural, and community levels. Future research should focus on understanding the epidemiology of cervical cancer and the social factors among the ethnic groups of women.

Post Hysterectomy Discharge Destination and Risk of Hospital Readmission in Elderly Women

Churley-Strom, Ruth Ann 01 January 2015 (has links)
In elderly women, discharge after gynecologic surgery is often associated with increased morbidity. Little information exists about elderly women's discharge destination after gynecologic surgery and the outcome of early hospital readmission. The purpose of this study, conceptualized using the quality health outcomes model, was to examine whether post hysterectomy discharge destination is an independent predictor of 30-day hospital readmission in women age 65 and older. Examination of covariates included patient age, race, medical comorbidity and complications of care, as well as surgical anatomic approach and operative technique. This study involved use of a retrospective cohort design and data from 10,598 cases contained in the Healthcare Cost and Utilization Project 2010 and 2011 California State Inpatient Databases. Results of the bivariate analysis showed a statistically significant association between discharge destination after hysterectomy and 30-day hospital readmission. Additionally, the results of multivariate logistic regression revealed the odds of readmission after discharge with home care were 2.99, p < .001, 95% CI [2.29, 3.67] times greater when compared with discharge home for self-care and 5.99, p < .001, 95% CI [4.68, 7.43] times greater with discharge to continuing inpatient care versus home for self-care. This study may lead to positive social change for elderly women by informing health care providers about the odds of early hospital readmission associated with discharge destination after hysterectomy. Further, this information may stimulate development of interventions to improve health care practices for elderly women preparing for hospital discharge after hysterectomy.

Using Social Cognitive Theory to Predict Counseling Behaviors in Registered Dietitians

Guerrero, Marianela 01 January 2018 (has links)
Obesity and morbid obesity affect more than 30% of Americans, which emulates the rate of smoking as the leading preventable cause of disease and death in the United States. The prevalence of obesity among adults in the United States increased dramatically between 1980 and 2010 (16% to 36%). The integration of the social cognitive theory (SCT) constructs such as self-efficacy, self-control, environment and expectations in the study instrument allowed identifying the impact of personal, social and economic factors on Registered Dietitians (RDs) counseling behaviors with obese clients. The goal of this quantitative cross sectional study was to investigate the association between RDs counseling behaviors and weight loss of clients using SCT. The sample of 150 RDs affiliated to the American Dietetic Association completed a survey to gather counseling behaviors with weight loss clients and SCT constructs. Data were analyzed using multiple regressions. The study showed a significant relationship between three SCT constructs such as self-efficacy in overcoming barriers, counseling environment and self-control with RDs counseling behaviors. The Spearman's rho correlations analyses between independent and dependent variables showed positive relationships between self-efficacy in overcoming barriers in counseling sessions and RDs counseling behaviors .34. The study adds to the literature on weight loss and RDs' counseling skills and creates the foundation for further research studies to reduce obesity by improving counseling skills among RDs.

Vitamin D and Age-Related Macular Degeneration

Hemphill, Mandy 01 January 2017 (has links)
Age-related macular degeneration (AMD) is the leading cause of vision loss in individuals aged 50 years and older and is estimated to affect as many as 11 million individuals in the United States. The purpose of this study was to examine the association between vitamin D and AMD disease progression. The life course epidemiology framework model was used to explore how vitamin D level as a risk factor may have an association to AMD disease through time. Data in the 2005-2008 National Health and Nutrition Examination Survey (NHANES) database were collected on vitamin D levels and identified stages of AMD level based on graded fundus eye exams from an available sample size of 5,604 participants. A quantitative cross-sectional study approach was used to address this gap in knowledge. A bivariate analysis was used to examine each independent variable (age, race/ethnicity, smoking status, and diabetes) to the dependent variable AMD from the 2005-2008 NHANES dataset. A multivariate logistic regression analysis was performed with AMD including each independent variable found to be significant. The findings from this study failed to suggest an association between vitamin D levels to AMD, with or without the covariates included in the model. There was not an association found between vitamin D level and presence of AMD. An association was found between age, smoking, and race to presence of AMD in each of the bivariate models. The findings from this study could be used for positive social change by encouraging medical and public health agencies to target screening programs at high-risk age, smoking, and race groups. There remains to be conflicting data in the literature. This study adds to the body of literature suggesting that higher levels of vitamin D are not necessarily beneficial as they pertains to AMD.

Wellness Intervention as a Quality of Life Predictor in Mentally Ill Veterans

Ellis, Tosha Lashon 01 January 2016 (has links)
Veterans with serious mental illness (SMI) are at high risk of developing conditions such as insulin resistance, obesity, and smoking, which may lead to chronic medical problems. As a result, the morbidity and mortality of people with SMI are high compared to the general population. It appears that integrated care improves the wellbeing of veterans; however, there is a gap in the literature on wellness-based interventions for veterans with SMI. The purpose of this cross-sectional study was to evaluate the association between a wellness intervention for veterans and their perceived quality of life (QOL). Social cognitive theory was the theoretical lens through which this study was conducted. It was hypothesized that there is an association between veterans’ involvement in the wellness component of a program and their perceived QOL. The program is a specialty VA service known as Mental Health Intensive Case Management (MHICM). A total of 112 veterans served by a single MHICM program in the U.S. Southeast completed a validated VA survey that measures health related QOL. A chart audit was conducted to gather information such as years served by the program and type of wellness services received. Regression modeling was used to assess the relationship between a veteran’s involvement in the wellness interventions and his or her perceived QOL. The study results showed that the interventions were not significant predictors of veterans QOL. Two covariates, age and gender, were found to be significant predictors, but each accounted for less than 7% of the variance. The study findings show the need for further research to explore the role of wellness interventions in a veteran’s recovery. Social change may result from encouraging veterans with SMIs to participate in self-rated QOL measures.

Parental Confidence in U.S. Government and Medical Authorities, Measles (Rubeloa) Knowledge, and MMR Vaccine Compliance

Leonard, Wendy 01 January 2015 (has links)
Parents' refusal to immunize their children with the measles, mumps, and rubella (MMR) vaccine has resulted in a surge of measles outbreaks in the United States. The purpose of this correlational study was to examine the relationships between parental knowledge and trust of the MMR vaccine, and their trust in government and medical authorities. The theoretical foundation for this study was the health belief model (HBM). This study determined if there was any relationship between general trust in doctors/governments (i.e., the predictor variable) and attitudes toward MMR vaccine (i.e., the sole dependent variable), and whether gender, age group, or level of education moderated that general trust. A Survey Monkey subscriber database and researcher-developed survey was used to identify and email 2,500 parents of immunization-aged children, resulting in 237 respondents who met the required parameters. The analysis revealed a significant, positive relationship between the criterion and predictor variables, R = .32, R2 = .10, F(1, 235) = 26.39, p. < .001, regardless of gender, age, or education, suggesting an association between higher trust and greater likelihood of a parent allowing vaccination. This study offers significant insights for positive social change by providing pediatricians, primary health care providers, and vaccine educators, with information for communicating with vaccine-hesitant parents: It is not enough to address parental concerns of vaccine safety, efficacy, and necessity. It is also not enough to provide evidence-based scientific data, as doing so has been proven to be ineffective "and for some parents counter-productive" when government and medical authorities are sited as the source. What we need to do is start focusing upon the role of parental trust, including how to best establish that trust, and equally important, what steps are necessary to sustain that trust.

The Association Between Dietary Patterns and Diabetes Status Among U.S. Adults

Richardson, LaTonia 01 January 2015 (has links)
Type 2 diabetes mellitus, or T2DM, is a leading cause of preventable death in the United States. Multiple studies have found that certain dietary patterns can significantly influence the risk of T2DM. The purpose of this study was to understand the dietary patterns associated with diabetes by comparing the relative adherence to these dietary patterns by individuals in 5 stages of diabetes: no diabetes, undiagnosed prediabetes, diagnosed prediabetes, undiagnosed diabetes, and diagnosed diabetes. Using the health belief model as the theoretical foundation, the primary research question examined whether adherence to specific dietary patterns significantly differed between individuals in different stages of diabetes. This question was important for understanding the dietary behaviors of individuals in early or unknown stages of diabetes that may lead to more harmful health consequences. Using data from the National Health and Nutrition Examination Survey (n = 15,237), multiple logistic regression analyses compared the odds of adherence to specific dietary patterns, adjusting for covariates. There was no statistically significant association between dietary pattern adherence and diabetes status. However, certain covariate factors-such as age and gender-were found to significantly influence the odds of high adherence to certain dietary patterns. Specifically, males were significantly more like than were females to adhere to diets associated with increased T2DM risk, and adults aged 50 years and older were significantly more likely than were younger adults to adhere to diets associated with decreased T2DM risk. The impact of these findings could lead to more targeted interventions promoting better eating habits and reduced T2DM incidence among U.S. adults aged 20 years older.

Use of Maternal Health Services and Pregnancy Outcomes in Nigeria

Umar, Abubakar Sadiq 01 January 2016 (has links)
Maternal health services (MHS) provide primary, secondary, and tertiary levels of prevention to achieve better pregnancy outcomes. However, use of prenatal and natal services among Nigerian women has been ranked among the lowest in the world and, consequently, the country is among the 10 countries with the highest maternal mortality ratio. Moreover, nationwide community-based studies on the use of maternal health services in Nigeria are limited. To address this gap, this quantitative, cross-sectional study analyzed the 2008 Nigerian Demographic and Health Survey (NDHS) data to identify whether Nigerian women's biological, cultural, and socioeconomic characteristics are associated with their use of MHS and pregnancy outcome as measured by number of antenatal visits, place of delivery, and fetal outcome. The Anderson's health behavior model was used as the theoretical framework for this study. Respondents were women aged 15 - 49 years (N= 31,985), who had given birth between January 2003 and December 2008. Bivariate and multiple logistic regressions were conducted. The results indicated that religion, education, income, and availability of skilled health workers showed consistent significant statistical association with both the number of ante natal care (ANC) visits and place of delivery even after controlling for covariates. Overall, these findings have potential for social change on the choice of public health interventions with collaboration with social services such as education, community, and labor sectors. Further, a systematic involvement of local communities is needed to drive specific culturally-sensitive interventions.

The Relationship between Self-Directedness and Health Promotion in the Elderly

Hulsman, Barbara L 01 May 2011 (has links)
With the number of people living longer and with more chronic problems, it is important that health educators examine who they are educating as well as the methods and circumstances of the education. The purpose of this study was to identify the relationship between self-directedness and health promotion in the elderly. A convenience sample of 108 elders who use Senior Centers in rural East Tennessee comprised the study group. The sample was asked to complete the Self-Directed Learning Readiness Scale, the Health Promoting Lifestyle Profile II, and a demographic information survey at a regular meeting of a Senior Center. A positive relationship (r=.394; p<.005) was found between self-directedness as a measure of intrinsic motivation with participation in health promoting behaviors. Demographic information was used to describe the sample and was also used to determine if there was a relationship between any of the demographic items and health promotion practices or self-directed learning readiness. Participation in religious/spiritual activities was significant for both self-directed learning readiness and health promotion practices. Pender’s Revised Health Promotion Model and the Personal Responsibility Orientation Model provided an excellent basis for this study. The study confirmed the need for personal motivation in the elderly to accomplish increased participation in health promotion practices. Both self-directed learning readiness and health promoting behaviors were reviewed for consideration of previous research in the area, and theoretical perspectives. The key implication for practice is that health educators need to understand the motivation of their client prior to educating them regarding an aspect of health promotion. Recommendations for research include more qualitative studies. Almost all the studies available at present are quantitative and the reason for participation needs further investigation. Qualitative studies would enhance the information regarding the reasons for participation in health promotion.
