Body Mass Index and Missing Data: Examining the Levels, Patterns, and Impacts of Missing Data in a Large Cohort Study of Canadian Youth
(University of Waterloo, 2022-12-19)Missing data are generally unavoidable in survey-based research. Small amounts of random missingness may not pose significant problems; however, issues arise when data are missing in large proportions or when missingness ... -
Breast cancer survivor functional changes immediately following treatment: quantifying mechanisms of strength deficits and compensatory kinematic and muscular strategy adaptations
(University of Waterloo, 2021-11-04)Breast cancer is prevalent among Canadian women, but treatments may cause functional impairments among survivors. Over 22,000 Canadian women join the survivor population yearly (Brenner et al., 2020). Despite this substantial ... -
Bridging the gap between physical activity evidence and practice for older adults with osteoporosis and frailty
(University of Waterloo, 2021-12-09)Exercise prescriptions that include moderate or high intensity progressive, resistance training, and functional and balance training may improve physical functioning and disability outcomes and prevent falls in older adults ... -
Cannabis use, retail availability and legal sanctions in Canada: Differences by neighbourhood deprivation, individual socioeconomic factors, and race/ethnicity.
(University of Waterloo, 2022-09-26)Background: Cannabis legalization in Canada represents one of the most significant changes in substance use policy over the past century. One of the primary objectives of cannabis legalization is to reduce illicit trade ... -
Cardiovascular responses of women to orthostatic stress, the effects of the menstrual cycle and age, and a comparison to men
(University of Waterloo, 2010-08-10)Young women are known to exhibit a greater incidence of orthostatic hypotension than men. The exact mechanisms for this are unclear and it has been proposed to be related to cardiac filling, peripheral resistance, and/or ... -
Caregivers in distress: Using interRAI assessments to target and evaluate community based interventions
(University of Waterloo, 2017-01-19)Background: Informal caregivers have a fundamental role in our society with the provision of unpaid care for family members or friends that may otherwise be unable to live in their homes. However, caregivers may jeopardize ... -
Cerebrovascular hemodynamics in older adults: Associations with lifestyle, peripheral vascular health and functional decline
(University of Waterloo, 2013-04-25)In today’s aging population, cerebrovascular health plays a pivotal role in maintaining independence. The identification of early markers of change might help to plan more appropriate preventative and/or therapeutic measures. ... -
Cerebrovascular Hemodynamics, Postural Stability, Gait Dynamics, and Falls in Older Adults
(University of Waterloo, 2018-04-26)Injurious falls in community-living older adults are associated with standing up suggesting that cerebral hypoperfusion following a postural transition might be a contributing factor. A large population study has recently ... -
Characterization of the effect of the menstrual cycle, estradiol and Fads2 transcript variants on fatty acid composition and enzyme expression
(University of Waterloo, 2016-08-29)Estrogen is believed to regulate fatty acid composition based on observations of differences between men and women, and changes associated with altered estrogen levels in women during pregnancy, menopause and hormone ... -
Characterization of the effects of sex, pregnancy, and 17β-estradiol on docosahexaenoic acid biosynthesis
(University of Waterloo, 2013-09-27)Docosahexaenoic acid (DHA) is an omega-3 polyunsaturated fatty acid (n-3 PUFA) required for fetal neurodevelopment. Increased DHA levels are associated with 17β-estradiol levels, as DHA is higher in women relative to men ... -
Characterizing a Novel Enzyme Involved in Cardiolipin Remodelling
(University of Waterloo, 2023-12-05)Background: Cardiolipin (CL) is a specialized dimeric phospholipid comprising approximately 25% of total phospholipids in the inner mitochondrial membrane in eukaryotes, where it functions in energy metabolism, autophagy ... -

(University of Waterloo, 2022-01-05)In any given year, one in five Canadians experience mental illness. The majority of mental illnesses originate in adolescence or young adulthood. Many complex factors can contribute to this, including substance use. However, ... -
Characterizing site-specific body composition of older adults and their associations with strength, functional capacity, and metabolic health
(University of Waterloo, 2021-06-03)Background: Ageing is associated with skeletal muscle atrophy and increased intramuscular adipose tissue. Emerging evidence indicates that specific muscle groups may be largely responsible for the ageing-related degradation ... -
Characterizing the Roles of Myoregulin and Dwarf Open Reading Frame in Regulating Calcium Homeostasis in Muscle
(University of Waterloo, 2024-01-26)The sarco(endo)plasmic reticulum Ca2+-ATPases (SERCAs) are responsible for inducing muscle relaxation and are integral to the maintenance of intracellular calcium (Ca2+) homeostasis. As such, their activity is modulated ... -
Cognitive control, conflict monitoring, and aerobic exercise.
