Physical activity, body mass index, and health-related quality of life in Canadian adults.

摘要: Purpose: Physical activity (PA) positively influences health-related quality of life (HRQL), whereas obesity is associated with significant HRQL impairments. Active�obese persons often have similar or lower risk cardiovascular outcomes and mortality than inactive�healthy weight persons; however, the combined PA�weight status effects on are unclear. The aim was to investigate association PA body mass index (BMI) in Canadian adults older adults. Methods: Cross-sectional data included 110,986 participants =18 yr from 2005 Community Health Survey, representing an estimated 22,563,527 Canadians. indicators included: Self-Rated (SRH), Participation Activity Limitation due illness/injury (PAL), Total Disability Days (physical + mental) during past 14 d (TDD). Prevalence adverse by BMI, PA, BMI�PA categories. Adjusted logistic regression used assess odds BMI�PA. Analyses were stratified sex age (18�44, 45�64, =65 yr). Results: In both men women all ages, inactive individuals had greater likelihood fair/poor SRH, sometimes/often PAL, at BMI levels; conversely, active individuals, being underweight, overweight, obese little effect SRH PAL. Associations weaker for TDD, where greatest influence inactivity underweight. Overweight showed less males adults, underweight stronger adults. Conclusions: When examining combination, emerges as more important correlate HRQL, regardless status. This reinforces importance health over above benefits related loss maintenance
