In the aging population, poor sleep quality is a concern as 46% of individuals 65 years and up reported insomnia, an indicator of poor sleep quality, which has been associated with dementia. Sleep quality can be dissected into two categories: objective, and subjective sleep measures. Objective sleep quality are measurable variables like sleep duration, and subjective sleep quality is how an individual perceived their nights rest. Because there are two aspects to sleep quality, an important consideration is how these two aspects differ? Subjective sleep quality is closely linked to subjective well-being and mental health outcomes such as depression, anxiety, and mood disorders. Furthermore, there is a mismatch between subjective and objective sleep quality in elderly individuals, further emphasizing the difference between subjective and objective sleep quality in the aging population. Hence, I will investigate how mental health factors like anxiety, depression, and mood disorders can predict subjective sleep quality and sleep duration in an aging population. Data was obtained from the Canadian Longitudinal Study on Aging, a study with 50,000 participants from 45-85 years of age. Perceived sleep quality was obtained through a 1-5 scale (5= worst perceived sleep quality). Sleep duration was measured as the number of hours slept. Onset, absence, persistence, and the recovery of anxiety, depression, and mood disorder at will be considered for mental health. Changes in mental health status and lifestyle will be analyzed at baseline (2015) and follow-up (2018) in regards to perceived sleep quality and sleep duration. It is expected that individuals with different mental health status will have different perceived sleep quality and sleep duration at the follow-up stage.
