Environmental Exposures And Aging., Daniel Chris Gomes Dec 2023

Environmental Exposures And Aging., Daniel Chris Gomes

Electronic Theses and Dissertations

In recent years, research into air pollution has shown that exposure to certain components in air pollution, primarily PM2.5 can accelerate biological aging and thereby lead to increased susceptibility to multiple diseases. We hypothesize that prolonged exposure to air pollutants can result in premature aging leading to extensive tissue dysfunction and susceptibility to diseases. To examine this, we exposed mice to PM2.5 for 9, 15, and 21 days, then measured the telomere lengths, cellular senescence, and histone methylation patterns of multiple cell types. We found consistently increased telomere attrition, cellular senescence and advanced age-consistent histone methylation patterns in groups exposed …


Intersectional Social Inequalities And Cognitive Functioning Among Community-Dwelling Older Adults In England: A Decomposition Analysis Of The Mediating Role Of Loneliness, Chantel Walwyn Dec 2020

Intersectional Social Inequalities And Cognitive Functioning Among Community-Dwelling Older Adults In England: A Decomposition Analysis Of The Mediating Role Of Loneliness, Chantel Walwyn

Electronic Thesis and Dissertation Repository

Normative cognitive decline is an emerging public health issue for older adult populations. It is necessary that we take an intersectional approach to examining heterogeneity in cognitive health outcomes. Using complex longitudinal survey data from the English Longitudinal Study of Ageing (ELSA), multiple linear regression models were used to examine the relationship between intersectional group membership based on age, education, and sex, and change in cognitive functioning domains (memory function, and executive function) over an 8-year period. Three-way decomposition analysis was also used to examine the mediating effect of loneliness on the association between intersectional group membership and the change …


Comorbidities And Medication Adherence Among Older Individuals Living With Hiv In The United States, Amanda M. Kong Jun 2019

Comorbidities And Medication Adherence Among Older Individuals Living With Hiv In The United States, Amanda M. Kong

Dissertations and Theses

The number of people living with HIV (PLWH) ≥65 years old is increasing in the United States (US) as PLWH live longer. In 2015, there were nearly 1 million people living with diagnosed HIV in the US and under 10% were age ≥65. By 2035, the proportion of PLWH in this age group is projected to be 27%. Like the general population of elderly individuals, as they age, PLWH face age-related comorbidities, many of which require routine medical care and daily medications, in addition to daily antiretroviral therapy (ART) for treatment of HIV. Previous research has found that PLWH develop …


Effects Of Medications With Anticholinergic Properties And Opioids On Cognitive Function And Neural Volumetric Changes In Elderly Australians, Malinee Neelamegam Apr 2019

Effects Of Medications With Anticholinergic Properties And Opioids On Cognitive Function And Neural Volumetric Changes In Elderly Australians, Malinee Neelamegam

USF Tampa Graduate Theses and Dissertations

Introduction: Multiple comorbidities are common among older adults. Pharmaceutical interventions are the most common form of medical management of the multiple health conditions that the older adult population faces. Almost 90% of adults aged 65 years and above take at least one prescription medication. Polypharmacy (5 medication or more) occurs with 50% of the older adult population. Most medications used to treat common ailments affecting the geriatric population have anticholinergic properties. These medications are known to cause a range of side effects from peripheral effects to central nervous system effects. These adverse effects are of particular concern in the older …


Challenges Of Aging With The Hiv Virus And Comorbidities, Rommie Navylia Abele Jan 2018

Challenges Of Aging With The Hiv Virus And Comorbidities, Rommie Navylia Abele

Walden Dissertations and Doctoral Studies

Since the introduction of antiretroviral therapy, the survival rate of infected HIV patients has been on the rise with a predicted increase by 2030. The longer a person lives with the virus, the more prone to HIV-associated chronic diseases he or she becomes, but it is not clear whether these diseases are solely from aging with the virus or from long-term use of antiretroviral therapy. Scientists demonstrated that the introduction of antiretroviral therapy led to an increased life expectancy yet early onset of comorbidities; however, they failed to address the challenges that people 50 years old or older face, as …


A Descriptive Study Of The Elderly In California Substance Abuse Treatment Programs, David Berenschot Jun 2017

A Descriptive Study Of The Elderly In California Substance Abuse Treatment Programs, David Berenschot

Electronic Theses, Projects, and Dissertations

As gerontologists may know, there are a great deal of studies and a variety of academic literature on the misuse of alcohol and prescription medication amongst the elderly population. While there is a plethora of information on alcohol and prescription misuse, there is little reported data about the prevalence of other substance misuse experienced by this population. This study aims to help to fill that gap in the data by using quantitative methods to describe the scope of substance abuse of individuals 55-years or older. This study utilizes data from the Treatment Data Set Admission (TEDS-A). The TEDS-A is a …

Obesity And Health Status Among Urban Vs. Suburban Elderly In Philadelphia And Surrounding Counties, Ockidde Dufayne Harris Jan 2004

Obesity And Health Status Among Urban Vs. Suburban Elderly In Philadelphia And Surrounding Counties, Ockidde Dufayne Harris

Theses and Dissertations

Obesity is a dangerous health condition affecting approximately 30% of all Americans and can be attributed to 300,000 deaths a year. Obesity has been found to disproportionately affect Blacks, Latinos, and those with lower SES. Although obesity is a problem for all age groups, its prevalence is highest among those 60-74 years of age. Studies have shown that there is an association between obesity and chronic conditions such as cardiovascular disease, arthritis, cancers, and type-2 diabetes. According to the Centers for Disease Control, chronic health conditions affect 80% of all elderly persons, many times limiting function and decreasing quality of …
