Associations of physical activity intensity and specific sedentary behaviors during after-school and weekend with overweight and obesity among preschool children.

Background: This cross-sectional study examined the association between physical activity (PA) intensity and specific sedentary behaviors (SB) among preschool children with overweight or obesity.

Methods: A sample of 1,115 preschoolers aged 3-6 years in Taipei City was recruited from March to April 2022. Parents completed a validated, self-administered survey assessing the child's PA intensity (light [LPA], moderate-to-vigorous [MVPA]) and specific SB (total sedentary time [ST], screen-based sedentary time [SST], non-screen sedentary time [NSST], electronic game screen time [EST]).

The mediating role of step counts in the relationship between diverse neighbourhood destinations and older adults' physical function.

Research has shown that access to activity-supportive neighbourhood destinations is associated with physical activity levels and physical functioning in older adults. However, the relative importance of different destinations and the mechanisms underlying these relationships remain unclear. We investigated (i) the relationships between the availability of diverse neighbourhood destinations and physical functioning in Taiwanese older adults and (ii) whether step counts mediated these relationships.

Light physical activity throughout the day and physical function in older adults: A cross-sectional study.

Research has demonstrated that habitual light physical activity (LPA) in later life may contribute to preventing muscle loss and disability in older adults. Given that LPA dominated overall physical activity duration throughout the day, investigating the impact of the timing of LPA on physical function among older adults is essential for optimizing health interventions. This cross-sectional study explored the association between LPA timing and performances in four physical function tests among older adults.

Dynapenia is associated with a higher risk of depressive symptoms among older adults.

Background: Depression affects the global burden of disability among older adults. Although dynapenia is related to disability and potential psychological health outcomes, its association with depressive symptoms remains uncertain. Accordingly, the objective of the current study was to investigate this association in older Taiwanese adults, applying the 2019 Asian Working Group for Sarcopenia (AWGS) classification of dynapenia.

Park proximity and all-day and time-specific physical activity and sedentary behaviour in older adults.

Background: Proximity to parks has been suggested as a factor influencing physical activity in older adults.

Methods: A cross-sectional analysis was conducted among 115 older adults (≥60 years).

Substituting sedentary time with physical activity in youngest-old to oldest-old community-dwelling older adults: Associations with body composition.

Introduction: Several studies have suggested that physical activity and sedentary behavior are strongly and independently associated with body composition and obesity. However, few studies have investigated whether substituting sedentary time with moderate-to-vigorous physical activity is associated with body composition in older adults, especially among those older than 75 years.

Methods: This study examined the associations between replacing sedentary time with physical activity and obesity indices in a sample of 199 community-dwelling older Taiwanese adults (52.

Relationship of sleep regularity with device-based sedentary behavior time and physical activity time in working adults.

Objectives: This study aimed to investigate the association of sleep regularity with time spent in sedentary behavior (SB) and physical activity (PA) in adults with full-time jobs.

Methods: This was a cross-sectional study. Adults aged 21-64 years with full-time jobs were recruited between August 2019 and December 2020 in Taiwan.

Domain-specific Physical Activity and the Risk of All-cause Mortality Among Middle-aged and Older Adults in Taiwan: A Prospective Cohort Study.

Background: The impact of meeting leisure-time physical activity (LTPA) recommendations and household physical activity (HPA) on all-cause mortality in the Taiwanese population is unclear. We aimed to investigate the relationship between sufficient LTPA and all-cause mortality in middle-aged and older Taiwanese adults and the role of HPA in those with insufficient LTPA.

Methods: This nationwide prospective cohort study included 4,960 participants aged ≥50 years from the Taiwan Longitudinal Study in Aging (TLSA) survey.
