Sleep Disruption And Cancer Incidence In A Southeastern Veteran Population, Alexandria F. Delage Jun 2016

Sleep Disruption And Cancer Incidence In A Southeastern Veteran Population, Alexandria F. Delage

Theses and Dissertations

Sleep disruption influences biological processes that can facilitate carcinogenesis. However, studies examining the relationship between sleep disruption and cancer risk have been inconclusive. This retrospective cohort study used de-identified data from the Veterans Administration (VA) electronic medical record to test the hypothesis that sleep disorder diagnoses among Veterans seeking care in the Southeast United States Service Network are associated with increased risk for cancer of the prostate, breast, colorectum, or total cancer (1999-2010, N=663,869). Sleep disorders were defined as patients with an in- or out-patient diagnosis as specified by the International Classification of Sleep Disorders. Cancer cases were defined as …


Low-Intensity Physical Activity And Cardiometabolic Risk Factors Among Older Adults With Multiple Chronic Conditions, Yueyao Li Jun 2016

Low-Intensity Physical Activity And Cardiometabolic Risk Factors Among Older Adults With Multiple Chronic Conditions, Yueyao Li

Theses and Dissertations

Introduction:

Cardiovascular disease (CVD) is the leading cause of death among older adults in the Unites States and is driven largely by cardiometabolic risk factors including elevated blood pressure and blood glucose. Studies have found the protective effect of moderate intensity physical activity (MIPA) and vigorous intensity physical activity (VIPA) on cardiometabolic risk factor; however, the association between light physical activity (LIPA) and cardiometabolic risk factor among older adults is not clear.

Objectives:

1. Examine the association between LIPA and cardiometabolic risk factors.
2. Examine whether the association between LIPA and cardiometabolic risk factor is moderated by multiple chronic conditions. …


Smoking-Related Stigma: A Public Health Tool Or A Damaging Force ?, Paula A. Lozano Jun 2016

Smoking-Related Stigma: A Public Health Tool Or A Damaging Force ?, Paula A. Lozano

Theses and Dissertations

Cigarette smoking is the leading cause of preventable death in the world. In an effort to address the tobacco epidemic, the World Health Organization’s Framework Convention on Tobacco Control (FCTC) has formulated a number of policies that are thought to reduce cigarette consumption by making smoking socially unacceptable. It is possible that tobacco control policies that aim to make smoking socially unacceptable may also result in the stigmatization of smokers. Social factors such as social norms and socioeconomic status may also influence the development of smoking-related stigma. While some researchers suggest that smoking-related stigma may be an important public health …


Progesterone-Only Oral Contraceptive Pill, Breast Cancer, Heart Disease, And Stroke, Marsha Ema Samson Jan 2016

Progesterone-Only Oral Contraceptive Pill, Breast Cancer, Heart Disease, And Stroke, Marsha Ema Samson

Theses and Dissertations

There is evidence from earlier studies that oral contraceptive pills may be a risk factor for certain chronic diseases, including heart disease, stroke, and breast cancer. Previous studies mainly focus on the estrogen component of combined (estrogen+ progestin) oral contraceptives (COCs) due to their popularity. This focus limits our understanding of progestin-only contraceptives and its relationship to commonly occurring chronic diseases. To provide insight into alternative methods of oral contraception, this dissertation explores the relationship between progestin-only oral contraceptive (POC) pills and heart disease, stroke, and breast cancer. We hypothesize that women using POCs are less likely to have certain …
