Objectively-measured outdoor time and physical and psychological function among older adults

Objectively measured physical activity and mortality in older adults.

Objectively measured and self-reported sedentary time in older Canadians

OBJECTIVE The aim of this study was to examine objectively measured total and self-reported leisure sedentary time among older Canadians by work status. METHODS The analysis was based on 1729 older adults (60-79 years) from the 2007/09 and 2010/11 Canadian Health Measures Survey. Work status, functional limitations, smoking, and perceived health were assessed by self-report and waist circumfe...

Objectively measured physical activity and kidney function in older men; a cross-sectional population-based study

Background kidney function declines in older adults and physical activity levels are low. We investigated whether higher levels of physical activity and lower levels of sedentary behaviour were associated with lower odds of low kidney function in older men. Methods cross-sectional study of 1,352 men from the British Regional Heart Study, mean (standard deviation) age 78.5 (4.6) year. Physical...

Predictors of Upper-Extremity Physical Function in Older Adults

  Background: Little is known about the influence of habitual participation in physical exercise and diet on upper-extremity physical function in older adults. To assess the relationship of general physical exercise and diet to upper-extremity physical function and pain intensity in older adults.   Methods: A cohort of 111 patients 50 or older completed a sociodemographic survey, the Rapid Asse...

Reliability of Objectively Measured Sedentary Time and Physical Activity in Adults

BACKGROUND In adults, a minimum of 3-5 days of accelerometer monitoring is usually considered appropriate to obtain reliable estimates of physical activity (PA). However, a longer period of measurement might be needed to obtain reliable estimates of sedentary behavior (SED). The aim of this study was to determine the reliability of objectively assessed SED and PA in adults. METHODS Eighty-sev...
