Grant: Summer Program in Aging

Dementia is a growing concern in Canada with more than 1.7 million people expected to have dementia in 2050. Given the major impact that dementia has on families, caregivers, and the healthcare system, it is important to recognize early signs and modifiable factors. Research has shown that certain living environments (with poor air quality, high noise levels, and exposure to pollutants) may negatively affect brain health. Access to natural spaces, such as parks, on the other hand, may help protect thinking and improve wellbeing. This study aims to explore how different aspects of the living environment relate to changes in thinking/memory, behaviour, and overall quality of life in older Canadian adults who do not have dementia. We will use data from the Canadian Platform for Research Online to Investigate Health, Quality of Life, Cognition, Behaviour, Function, and Caregiving in Aging (CAN-PROTECT). CAN-PROTECT is a nationwide online study in which participants complete questionnaires on thinking, behaviour, lifestyle, quality of life, and the living environment. We will assess whether participants with greater exposure to air and noise pollution and harmful chemicals, and lower access to green spaces, experience more difficulties with everyday thinking or changes in behaviour. We will also assess whether those with greater exposure to these living conditions have a lower quality of life. We will examine whether these relationships differ in men and women. Given that changes in thinking and behaviour usually appear before dementia is diagnosed, identifying environmental stressors that may contribute to changes in thinking and behaviour early on can help identify groups who may benefit most from prevention efforts. Our study may also inform public health strategies, urban planning, and environmental policies that support healthier aging and living environments for all Canadians.
