Compositional Associations Of Objectively Measured Activities With Declined Cognitive Function In Older Adults: NEIGE Study

Objectively measured physical activity and mortality in older adults.

Associations of objectively measured physical activity with lower limb function in older men and women: findings from the Older People and Active Living (OPAL) study.

Associations of objectively measured physical activity (PA) with objectively measured lower limb function in adults age 70 and older were studied. Lower limb function was assessed using the Short Physical Performance Battery (SPPB) and PA by an accelerometer providing mean daily counts per minute (CPM), mean daily steps and minutes of moderate or vigorous PA (MVPA) per day. A minority (32 [13%]...

Objectively measured sleep and β-amyloid burden in older adults: A pilot study

BACKGROUND/AIMS Although disturbed sleep is associated with cognitive deficits, the association between sleep disturbance and Alzheimer's disease (AD) pathology is unclear. In this pilot study, we examined the extent to which sleep duration, sleep quality, and sleep-disordered breathing (SDB) are associated with β-amyloid (Aβ) deposition in the brains of living humans. METHODS We studied 13 o...

Associations between objectively-measured sedentary behaviour and physical activity with bone mineral density in adults and older adults, the NHANES study.

BACKGROUND Lack of physical activity (PA) is an important modifiable risk factor for bone mineral density (BMD). Time spent in sedentary behaviour (SB), or time spent in non-exercising seated and reclining postures, has recently emerged as a new public health risk, independent of the amount of time someone spends being active. As national surveys report that adults spend on average 8h per day b...

Association of Objectively Measured Physical Activity With Cardiovascular Risk in Mobility‐limited Older Adults

BACKGROUND Data are sparse regarding the impacts of habitual physical activity (PA) and sedentary behavior on cardiovascular (CV) risk in older adults with mobility limitations. METHODS AND RESULTS This study examined the baseline, cross-sectional association between CV risk and objectively measured PA among participants in the Lifestyle Interventions and Independence for Elders (LIFE) study....
