Background:
Obesity is associated with impairments in health-related quality of life (HRQL), whereas physical activity (PA) is a promoter of HRQL.
Purpose:
The aim of this study was to investigate the interaction between BMI and PA with HRQL in younger and older Canadian adults.
Methods:
Data from the 2012 annual component of the Canadian Community Health Survey (N = 48,041; = 30 years) were used to capture self-reported body mass index (BMI-kg/m2), PA (kcal/kg/day, KKD), and HRQL. Interactions between PA and age on the BMI and HRQL relationship were assessed using general linear models and logistic regression.
Results:
Those younger (younger: μ = 0.79 ± 0.02; older: μ = 0.70 ± 0.02) and more active (active: μ = 0.82 ± 0.02; moderately active: μ = 0.77 ± 0.03; inactive: μ = 0.73 ± 0.01) reported higher HRQL. Older inactive underweight, normal weight, and overweight adults have lower odds of high HRQL.
Conclusion:
PA was associated with higher HRQL in younger adults. In older adults, BMI and PA influenced HRQL.
