Daily sedentary time and physical activity as assessed by accelerometry and their correlates in older adults (2019)

Dutch older adults spend on average 65% of their waking time sedentary. Older adults’ sedentary time differs by age, sex, education and BMI groups. The combination of high sedentary time and low physical was associated with higher age, higher BMI, and slower walking speed compared to the combination of low sedentary time and high MVPA. This suggests that increasing light activity might be an effective and feasible strategy in older persons to reduce sedentary time. Future studies should assess whether low- sedentary and high-light physical activity are associated with improved long-term health outcomes (also independent of MVPA).
