Successful aging Flashcards
T/F Successful aging is hard to define because it is ambiguous and qualitative in nature
T
What is not one of the 3 components of successful aging
- avoiding disease and disability
- maintaining cognitive and physical function
- maintaining friends throughout adulthood
- engagement with life
not friends
What does it mean if a person has a walking speed less than 0.8 m/s?
They are at very high risk of poor health and physical function
SPPB
short physical performance batter: a tool to measure physical function, mainly lower extremity
SPPB tests
Balance (x3), gait speed, chair stand
T/F cognitive decline leads to increased hospitalization and injury but not dependence and death
false, all increase
What is older adult obesity likely caused by?
age-related changes in muscle composition (sarcopenia obesity)
Which of the following is not an effect of older adult obesity?
- physical disability
- cognitive decline
- decreased ROS
- increased inflammatory cytokines
decreased ROS, there is actually in increase
What components atrophy in sarcopenia?
type II fibers and MUs
??% muscle loss occurs per year after 50
1-2%
dynapenia
age-related decline in strength, not related to loss of muscle mass, but decreased quality and NM control
What grip strength predicts mobility issues?
<26 kg in men, <16kg in women
What is the proposed cause of chronic pain
change in sensory & immune function
T/F Chronic pain is highly prevalent in older adults
True, 70-80%
What is the most common chronic pain
knee pain from OA
Which of the following is not a behavioural risk factor for health conditions
- nutrition and sleep
- environment
- psychosocial aspects
- functional capacity
- inactivity not functional capacity
What does BMI >30 predict
ADL issues 5 years earlier
T/F People with high BMI are at risk for frailty and sarcopenia
false, those are risks of low BMI. High BMI is risk for functional decline
What is the cutoff between sarcopenia obesity and obesity
there isn’t one
T/F physical inactivity is the most common behavioural risk factor in obesity
T
T/F loss of lean muscle mass isn’t associated with inactivity
F, it is
Which of the following does not decrease with age?
- sleep time
- sleep efficiency
- sleep latency
sleep latency increases (longer to fall asleep)
What amount of sleep decreased function and increases mortality
less thant 6-7h
what environmental factor does not affect successful aging
- proximity to gym
- temperature fluctuations
- mobility barriers
- pollution (respiratory)
pollution (respiratory), temperature fluctuations, mobility barriers
