Electronic Thesis and Dissertation Repository

Regular physical activity is a well-known protective factor against chronic disease and strongly correlated with healthy aging. However, as physical activity levels tend to decline with age, there is a need to identify barriers which prevent older adults from being physically active. This thesis investigated the relationship between socioeconomic status and meeting physical activity guidelines of 150 minutes or more of moderate- to vigorous- intensity physical activity among middle-aged to older adults in Canada. Using cross-sectional data from the baseline assessment of the Canadian Longitudinal Study on Aging, block-wise multivariable logistic regression was performed to assess the association between socioeconomic …

Weighted crude and adjusted Cox proportional hazards models were fitted with time-dependent covariates. The adjusted models were controlled for age, sex, BMI, cigarette smoking, alcohol consumption, diabetes mellitus, arterial hypertension, heart disease, education, and income.

Results: A total of 9,950 respondents were included, of which 190 developed glaucoma within the 10-year follow-up period. The adjusted hazards ratios for physical activity …

The Association Between Social Cohesion And Physical Activity In Communities Across Canada: A Multilevel Analysis, Calvin Yip

Electronic Thesis and Dissertation Repository

Background: In Canada, only 15% of adults meet physical activity guidelines for optimal health. Previous research has suggested that social cohesion may promote physical activity.

Objective: To assess the association between social cohesion and physical activity among adults aged 18 to 64 years in Canada.

Methods: Data from the 2009-2010, 2011-2012, and 2013-2014 cycles (N=245,150) of the Canadian Community Health Survey were used. Physical activity level was operationalized using average daily energy expenditure, social cohesion was determined by self-rated sense of belonging to the local community, and communities were represented by Canada’s Forward Sortation Areas. Multilevel regression models were used …
