Developing An Online Questionnaire To Investigate The Covid-19 Pandemic’S Impacts On Social Isolation And Health In Older Adults Living With Multimorbidity: A Pilot Study, Patricia Nistor

Electronic Thesis and Dissertation Repository

Introduction. Social restrictions preventing the spread of COVID-19 possibly increased social isolation and loneliness. The validity and reliability of a questionnaire assessing the COVID-19 pandemic’s impact on social isolation and loneliness in community dwelling older adults with multimorbidity was investigated.

Methods. A conceptual framework was developed to guide questionnaire construction. Participants were recruited through professional networks, comprising a convenience sample. Feedback interviews assessed usability and face validity. Content validity was assessed using a Content Validity Matrix, and construct validity through tests of association. Reliability of validated scales was assessed using Cronbach’s ⍺. Descriptive statistics and logistic regression were computed. …

Sleep And Multimorbidity In The Canadian Longitudinal Study On Aging, Shreni Patel

Electronic Thesis and Dissertation Repository

Sleep health is a latent construct comprising various sleep measures such as duration, quality, initiation, maintenance, and daytime sleepiness. This thesis compared the association of two measures of sleep health, a conventional summary score and a pooled index, with incident multimorbidity over a 3-year follow-up in 30,097 middle- to older-aged adults from the Canadian Longitudinal Study on Aging. At baseline, approximately 26% and 29% of participants with multimorbidity displayed poor sleep patterns according to additive and pooled indexing methods. Longitudinal analysis indicated that those with additive scores of 4 to 5 at baseline had a 1.54 (95% CI: 1.18, 2.03) …

Multimorbidity And Cognition Among Canadian Older Adults: A Three-Decade Perspective, Juan Camilo Vargas Gonzalez

Electronic Thesis and Dissertation Repository

Background: Scarce information exists about whether the relationship between multimorbidity and cognitive decline has changed over the past decades.

Objectives: 1) To summarize knowledge about the association of multimorbidity and cognitive decline by performing a systematic review. 2) To estimate the association between multimorbidity in two cohorts selected three decades apart. 3)To identify which multimorbidity combinations have the strongest associations with cognitive decline 4) To identify protective factors that reduce the risk of cognitive decline in the presence of multimorbidity.

Methods: We performed a systematic review following the PRISMA statement. We then addressed objectives 2-4 by analyzing data from two …

Health Care Utilization By Immigrants With Multimorbidity: A Population Based Cross-Sectional Study Of The 2015-2016 Canadian Community Health Survey (Cchs), Chinmoy Talukder

Electronic Thesis and Dissertation Repository

Immigrants face unique healthcare barriers, which can negatively impact their health and health service use. Those with multimorbidity face a particular challenge as multimorbidity is associated with increased need for healthcare. The purpose of this study was to compare healthcare utilization, as measured by number of visits to family physicians and specialists, between immigrants and Canadian-born populations with multimorbidity, stratified by sex and for specific chronic diseases. A cross-sectional analysis using 2015-2016 Canadian Community Health Survey (CCHS) was conducted. After adjusting for relevant covariates, no statistically significant differences in visits to family physicians or specialists were observed between immigrants and …

The Prevalence Of Multimorbidity Among People With Non-Affective Psychotic Disorders 10-Years After First Diagnosis, Myanca D. Rodrigues

Electronic Thesis and Dissertation Repository

Prior research suggests that people with psychotic disorders have an excess risk of individual chronic conditions, however less is known about their risk of co-occurring multiple chronic health conditions; that is, multimorbidity. The overall objective of this thesis was to examine the association between psychotic disorders and multimorbidity using two complementary studies. First, our systematic review and meta-analysis of fourteen studies found that people with psychotic disorders had an increased risk of 2+ chronic conditions relative to those without psychosis (RR=1.69, 95%CI=1.37,2.08). Second, our retrospective matched cohort study found that people with psychotic disorders treated by an early psychosis intervention …

Multimorbidity Among Adult Primary Health Care Patients In Canada: Examining Multiple Chronic Diseases Using An Electronic Medical Record Database, Kathryn Nicholson

Electronic Thesis and Dissertation Repository

Introduction: The coexistence of multiple chronic diseases within an individual, also known as multimorbidity, is an ongoing challenge for patients, caregivers and primary health care (PHC) providers. An enhanced understanding of the burden of multimorbidity in Canada is needed.

Objectives: This research had two main objectives. Objective One aimed to understand the prevalence of multimorbidity among adult PHC patients, as well as the patterns of unordered and ordered clusters of multiple chronic diseases. Objective Two aimed to determine the natural progression of multimorbidity over time, as well as the patient-, provider- and practice-level predictors of progressing into more complex clinical …
