Background: The optimal combinations of modifiable risk factors to be targeted in preventive dementia trials may vary across countries and settings. We aimed to identify the combinations of modifiable risk factors associated with cognitive change in Canadian adults.
Method: Population Attributable Fraction analyses on 30,097 participants from the Canadian Longitudinal Study on Aging and prevalence of 2, 3 and 4 risk combinations of the 12 modifiable risk factors identified in the 2020 Dementia Lancet report were estimated to note the ten most prevalent combinations.
Background: It has been suggested that up to 40% of dementia cases worldwide are associated with modifiable risk factors; however, these estimates are not known in Canada. Furthermore, sleep disturbances, an emerging factor, has not been incorporated into the life-course model of dementia prevention.
Objective: To estimate the population impact of 12 modifiable risk factors in Canadian adults including sleep disturbances, by sex and age groups, and to compare with other countries.
Objective: Middle-aged to older adults often exhibit the co-existence of poor sleep health and multimorbidity. We examined cross-sectional and prospective associations of pooled index of sleep health with prevalent and incident multimorbidity in the framework of an ongoing cohort study in Canada.
Methods: Data were from approximately 24,000 individuals from the Canadian Longitudinal Study on Aging (CLSA), an ongoing national study of community-dwelling adults aged 45-85 years at baseline.
Article Synopsis
- The study investigates the health outcomes of retired elite female rugby players in areas such as musculoskeletal, cognitive, mental, reproductive/endocrinological, and cardiovascular health compared to the general population.
- Out of 159 participants, a significant majority reported injuries during their careers, with many experiencing ongoing pain and a high incidence of concussions, which negatively impacted cognitive function.
- Despite some physical health challenges, retired players reported lower levels of anxiety and depression compared to the general population, indicating a complex relationship between their athletic careers and mental health post-retirement.
This paper presents results from the Smart Healthy Campus 2.0 study/smartphone app, developed and used to collect mental health-related lifestyle data from 86 Canadian undergraduates January-August 2021. Objectives of the study were to 1) address the absence of longitudinal mental health overview and lifestyle-related data from Canadian undergraduate students, and 2) to identify associations between these self-reported mental health overviews (questionnaires) and lifestyle-related measures (from smartphone digital measures).
