Abstract:
|
Background: Sedentary behavior (SB) and physical activity (PA) are important determinants of health in older adults. This study aimed to
describe the composition of accelerometer-measured SB and PA in older adults, to explore self-reported context-specific SB, and to assess
sociodemographic and functional correlates of engaging in higher levels of SB in participants of a multicenter study including four European
countries.
Method: One thousand three hundred and sixty community-dwelling older adults from the SITLESS study (61.8% women; 75.3 ± 6.3 years)
completed a self-reported SB questionnaire and wore an ActiGraph accelerometer for 7 days. Accelerometer-determined compositional
descriptive statistics were calculated. A fixed-effects regression analysis was conducted to assess the sociodemographic (country, age, sex, civil
status, education, and medications) and functional (body mass index and gait speed) correlates.
Results: Older adults spent 78.8% of waking time in SB, 18.6% in light-intensity PA, and 2.6% in moderate-to-vigorous PA. Accelerometry
showed that women engaged in more light-intensity PA and walking and men engaged in higher amounts of moderate-to-vigorous PA.
Watching television and reading accounted for 47.2% of waking time. Older age, being a man, single, taking more medications, being obese
and overweight, and having a slower gait speed were statistically significant correlates of more sedentary time.
Conclusions: The high amount of SB of our participants justifies the need to develop and evaluate interventions to reduce sitting time.
A clinically relevant change in gait speed can decrease almost 0.45 percentage points of sedentary time. The distribution of context-specific
sedentary activities by country and sex showed minor differences, albeit worth noting. |
