Rapid Rhino Vs. Merocel: A Retrospective Analysis Of Patients With Anterior Epistaxis Visiting Emergency Rooms In London, Ontario, Dhatri Shukla

Electronic Thesis and Dissertation Repository

When patients present to an emergency room (ER) with a nosebleed, one technique that physicians employ is the application of nasal packing. Merocel is a common nasal pack utilized in ER because of their low cost. Rapid Rhino is a nasal packing that is more comfortable for patients but is more costly than Merocel. Costing for epistaxis treatment is more than initial treatment costs and needs to consider rebleed rates. Using a retrospective cohort study design with covariates adjusted by propensity scores, we compared the costs associated with Merocel, and Rapid Rhino from the hospital and provincial healthcare perspectives. Merocel …

Fertility Preservation Discussions With Transgender People In Canada Prior To Beginning Medical Gender Affirmation, Emily K. Sanders

Electronic Thesis and Dissertation Repository

Background. Prevalence of fertility preservation discussions and procedures, participant characteristics associated with discussions, and prevalence of desire to parent are described.

Methods. Describes, for a clinical sample of < 16-year-olds: medical chart-recorded discussion and procedure prevalence, and desire to parent longitudinally. Describes self-reported discussion prevalence for a community sample of 14- to 39-year-olds. Bivariate and multivariable modified Poisson analyses were conducted for this sample.

Results. Discussion prevalence was confirmed for approximately 80% of the clinical sample, with approximately 20% unconfirmed. Self-reported discussion prevalence was 45% in the community sample. Non-binary gender with female sex at birth, greater family religiosity, and diagnosed mental health condition excluding depression or anxiety were crudely associated with less discussions. Multivariable analyses revealed no statistically significant predictors. Desire to parent was fairly consistent over time.

Conclusion. Discussions should be standard practice for …

An Intersectional Analysis Of Intimate Partner Violence In Canada, Isabella V. Aversa

Electronic Thesis and Dissertation Repository

Background: Intimate partner violence (IPV) is a recognized public health issue that can lead to poor mental and physical health outcomes. It is critical to take an intersectional approach to understanding the ways that social and interpersonal power impact IPV.

Methods: Random Forest was used to aid in social group selection when forming intersections. Multilevel analysis of individual heterogeneity and discriminatory accuracy (MAIHDA) was used to estimate the prevalence of IPV across intersections. Descriptive statistics were used to explore the context in which IPV occurred.

Results: The prevalence of IPV was greatest for cisgender women, transgender, and non-binary individuals, aged …

The Impact Of Interruptions In Gender-Affirming Medical Care During Covid-19 On Anxiety And Depression Among Trans And Non-Binary People In Canada: A Longitudinal Study, Sara Todorovic

Electronic Thesis and Dissertation Repository

Background. Transgender and non-binary (TGNB) populations experience disproportionally high levels of anxiety and depression; it is imperative we investigate how the COVID-19 pandemic may have impacted the mental health of TGNB communities. Methods. Among a Canadian sample of TGNB persons aged >=15 years, we used multiple linear regression to examine whether interruptions in gender-affirming care were associated with anxiety and depression, and whether that effect was modified by pre-pandemic mental health. Results. Anxiety and depression levels were high both pre-pandemic and during the pandemic. Approximately a quarter of TGNB persons experienced interruptions in hormonal care. After adjusting for confounders, there …

Interplay Between Shift Work, Psychological Distress, Sleep Quality, And Cognitive Performance, Rea Therese Alonzo

Electronic Thesis and Dissertation Repository

Shift work schedules are designed to maintain a continuous operation of goods and services. However, engaging in shift work may impact cognitive functioning. This thesis assessed the relationship between shift work and cognitive performance. Using cross-sectional data from the Canadian Longitudinal Study on Aging, multiple linear regression models were used to investigate the association between shift work and cognitive performance, as well as the moderating effects of psychological distress and sleep quality. Differences by sex and retirement status were also investigated. Shift work was significantly associated with poor performance for executive functioning but not for declarative memory. Poorer cognitive performance …

Correlates Of Preventable Emergency Department Visits In Canada: Evidence From The Literature And The Canadian Community Health Survey, Tammy Lau

Electronic Thesis and Dissertation Repository

Emergency department (ED) visits for primary healthcare-treatable conditions are preventable and indicate barriers to primary healthcare. The goal of this thesis was to explore the prevalence and key correlates of preventable ED visits among adults in Canada. Our systematic review found that the prevalence of these visits ranged from 4.3% to 59.1% and were associated with younger age, low education, low income, rural residence, and worse self-rated health. Our analysis of data from the 2015-2016 Canadian Community Health Survey found that 39.9% of adults with a regular healthcare provider considered their last ED visit to be preventable. In addition to …

The Impact Of School Nutrition Policy On Diet Quality Of Children And Youth In Canada, Victoria Gaudin

Electronic Thesis and Dissertation Repository

Improving diet quality is an important public policy initiative targeted to enhance population health worldwide. In this regard, school nutrition policy is an important means to promote healthy diet among children and youth. In Canada, six provinces implemented mandatory school nutrition policies at different times between 2005 and 2011. We investigated the impact of mandatory school nutrition policy on diet quality of Canadian children and youth using a quasi- experimental study design. Using 24-hour dietary recall data from the 2004 Canadian Community Health Survey (CCHS) Cycle 2.2 and 2015 CCHS-Nutrition, we constructed the Diet Quality Index (DQI). We used multivariable …

Social Determinants Of Health And Substance Use Among Women Living With Hiv In Canada: Inequalities And Impacts, Mostafa Shokoohi

Electronic Thesis and Dissertation Repository

The objective of this doctoral research was two-fold: 1) to estimate inequalities in social determinants of health (SDoH), health-related quality of life, and substance use among women living with HIV (WLWH) compared to the general population of women; and 2) to assess the impact of the SDoH clusters on illicit drug use and heavy alcohol drinking among WLWH. For the first objective, estimates were obtained from 1,422 WLWH aged 16+ in the 2013-2015 Canadian HIV Women’s Sexual and Reproductive Health Cohort Study (CHIWOS, time-point 1), and then compared with their counterparts estimated in 46,831 general population women in the 2013-2014 …

The Effects Of Child Restraint System Use And Motor Vehicle Collision Severity On Injury Patterns And Severity In Children 8 Years Old And Younger., Peyton A. Schroeder

Electronic Thesis and Dissertation Repository

Motor vehicle collisions (MVCs) are a leading cause of injury and death for children under the age of 14 years in North America. Children, eight years old or younger, are required to use a child restraint system (CRS) when travelling in a vehicle in Canada. In the present study, the hypothesis that head injury severity of children in this age group, seated in rear rows of vehicles in MVCs, will be influenced by the types of restraint systems used was not supported by the data; however, other secondary aspects of collision data were explored. There were injury patterns that involved …

Social Connectedness, Social Support And The Health Of Older Adults: A Comparison Of Immigrant And Native-Born Canadians, Natalie Iciaszczyk

Electronic Thesis and Dissertation Repository

Considerable research exists on the influence of social relationships for health in old age. However, few studies have compared the associations of social connectedness and social support with the health of older adults. Using data from the CCHS-Healthy Aging, this study examines how these constructs are related to the self-reported health status of immigrant and native-born adults aged 65+. Results show that social connectedness and social support are differently associated with health in later life; whereas connectedness is linked to better health, social support is negatively related with health once levels of social connectedness are considered. Furthermore, these associations hold …

The Experiences Of Black Men Living With Hypertension In Ontario, Canada: A Critical Narrative Study, Rob Haile
