AGEING Flashcards

1
Q

Define Aging and what are the 3 indicators

A
  • happens before physical signs become obvious
  • indicators of ageing:
    1. chronological age
    2. functional capacity
    3. life stage - used to classify people into groups

Q

Define chronological age

A
  • age since birth
  • used to determine eligibility for programs (ex. Canada Pension)
  • remains the dominant legal definition of when a person becomes “older”
  • everyone’s experience is different so you can’t lump them all together (doesn’t capture the heterogeneity of adults)

Q

Define functional age

A
  • observable individual attributes to assign to people to age categories:
    1. Physical appearance
    2. mobility
    3. Strength
    4. mental capacity
  • does not always match chronological age

Q

Old age & what age is rates of decline higher?

A

begins around late 70s to early 80s

Ageing in Context Documentary notes

A
  • some of the elders thought that the assisted living was like a prison and they wanted to get out

A
  1. Health care professionals were ill-prepared to adequately care for older adults
  2. Older adults rarely receive preventative care
  3. Older adults did not receive appropriate ore preventative measures
  4. Older adults bc of their age were excluded from proven medical interventions
  5. Older adults were excluded from clinical trials
43

A
  • pop is divided into age state such as youth, adulthood and old age
  • inequalities, or conflicts between age strata influence age relations
  • age grading sorts people into age strata and channels them thro age-graded roles and opportunity structures
  • intergenerational conflict bc of this
46
Q

what is the “structural lag”?

A
  • there’s a mismatch between opportunities that are their for them and their ability and strength

  2. recognition of old age cues
  3. stereotyped expectations
  4. modified speech behaviour
49
Q

patronizing communication - who is it used by

A
  • exists in nursing homes (regardless for all residents, regardless of regardless of cognitive ability)
  • used by staff with more negative attitudes towards ageing
50
Q

outcomes of modified speech behaviour - impact and what’s helpful vs. what isn’t helpful

A
  • stereotyped expectations can create self-fulfilling prophecy for older adults (reinforce dependancy)
  • internalizing negative stereotypes and self-perceptions
  • more exposure to elder speak means lower self-esteem
    Whats helpful:

    MODEL CAN EITHER GO 7A OR 7B
    7a. loss of personal control and self esteem
    7b. blessed psychological social activity
  7. negative age changes
    ** CYCLE REPEATS
    - negative feedback loop
52
Q

implications of stereotypes on health of older adults: self-fulfilling prophecy (negative stereotypes)

A
  • stereotypes affects cognitive and physical functioning
    1. poor performance on memory tests
    2. higher BP and heart rates
    3. decline in handwriting ability
  • *subliminal negative stereotypes
53
Q

impacts of stereotyping on middle-aged adults: self-fulfilling prophecy experiment

A
  • 3 groups of middle aged women and men (aged 48-62):
    1. told they were part of a study including people over 70 (indirect reminder of link between age and memory loss)
    2. told they were competing against people in their 20s
    3. told nothing (control group)
  • evaluated performance on a word-recall memory test (study a list of 30words for 2mins then recall)
    • Power of suggesting that they are associated with an older group resulted in the middle age group doing poorly (as if they were older adults in terms of memory)
54
Q

Communication Enhancement Model (CEM)

A
  1. encounter an older person
  2. recognition of cues on individual basis
  3. Modified communication to accommodate individual needs (back to step 2 if needed)
  4. Individual assessment for multi-focused interventions (back to step 3 if needed)
  5. empowerment of client and provider
    OUTCOMEs
    6a. optimized health, well-being and competence of elder
    6b. increased effectiveness and satisfaction of provider
  6. maximized communication skills and opportunities
    REPEAT
    -Far more person centred instead of stereotypes
    -Based on their actual abilities
    - Trial and error on some strategies - accommodate based on their actual needs and not stereotyped needs
    - Impact is that it should empower both the client and the provider (dyad- positive outcomes for both groups)
    -This will maximize the opportunities for communication skills and positive feed back loop
    - Prescribing the situation
55
Q

difference between CPA and CEM

A

CPA = descriptive model, stereotypic needs
CEM = prescriptive model, health promo perspective and individual needs
3 key areas:
1. Appropriate speech accommodation
2. supportive physical environment
3. positive social environment

56
Q

impact of positive self-perceptions (2)

A
  1. positive self-perceptions
    - better functional health
    - lived almost 8 years longer
  2. subliminal exposure to postive age stereotypes
    - improvement in motor function
57
Q

patterns of communication in Old Age: Baltes & Wahl Study - what is it and how did they go about it

A
  • list of behaviours that target the person, of social patterns and dyadic form of behaviour
  • suggestion, command, request was the most common among social partners (nursing staff)
  • compliance, cooperation was the most common among older adults
  • Observing communication in these facilities
  • Then looked at the nurses responses
  • Then looked at the dyadic relationship
  • They were more task focused
    Older adults were complying
58
Q

social behavioural analyses of the dependence-support script (dependant vs. independent behaviours)

A
  • dependant behaviours: supporter and attended with immediate positive reactions
  • independent behaviours: ignored in nursing home setting and followed by both independence-supportive and dependance-supportive behaviours (OA unsure about consequences of independent behaviour)
  • This was confusing bc the independent behaviour would be supported by the nurses and sometimes the independent behaviour would be supported by dependant behaviour (dependant - supportive script - ex. “ill get that for you” even tho the older adult is capable)
59
Q

modification of the dependency-support script (goal of intervention and the intervention itself)

A

Goal of Intervention:
- change the behaviour of social partners (increase responsively to independent behaviours)
- evaluate the consequence of such change
Intervention:
- participants had to design, conduct and evaluate a behaviour modification program
- taught nursing home staff :
1. communication skills
2. info about aging
3. behaviour management skills
** dont want staff to ignore anymore

60
Q

modification of the dependency-support script: design and results

A

Design and Results:

  • pre-post control group design to examine the change behaviour
  • observed an increase in independent-supportive behaviour among staff (increase in independent behaviours among older adults)
  • intervention was focused on the social environment (e. the nurses) and notion the older adults
  • it was focused on the social environment of the nurses - and just by training the staff there was a positive impact on the older adults
61
Q

personhood and dementia - how was it set up?

A
  1. communication predicament of aging model
  2. social context: long-term care (LTC) facility
  3. communication enhancing strategies:
    - personhood
    - simple sentence/ repetition
  4. participants: 71 LTC staff members
    Method: vignette evaluation
    ** situations were person centred vs. directive
62
Q

personhood and dementia: Results (2)

A
  1. personhood condition
    - staff rated positively
    (verbal/nonverbal characteristics and competent, respectful & satisfied)
    - resident rated positively
    (competent, satisfied with convo and more likely to actively engage, more able to participate in daily activities)
  2. personhood + simple Sentences/Repetition
    - strengthened effect of personhood
    (staff = less patronizing, resident = more competent)
63
Q

personhood and dementia: what does this mean? (4 results)

A
  1. communication matters
    - include “person”
  2. simple doesn’t mean short
    - short sentences are not helpful
    - simple = easy to understand/process
  3. paraphrase/repeat
    - when residents with dementia dont understand
  4. using communication enhancing strategies
    - enhancing both staff and residents
    enhances quality of care
64
Q

intervention using CEM model - how it was done, goal and what did they measure

A
  1. pre and post-training recordings
  2. 3 one hour communication training sessions:
    - limited lecture, group discussions and role play to practice new skills
    - Goal: reduce elder speak in nursing home
  3. Measures:
    - diminutives (honey, good girl etc.), inappropriate collective pronouns
    - mean length of utterance
65
Q

intervention effects is using CEM model

A
  • reduction in “honey, sweetie”
  • reduction in collective pronouns
  • more convos between resident and staff
66
Q

Rowe & Kahn Model of Successful Aging: how is the model set up, goal and critiques

A
  • center: successul aging
    above: minimize risk & disability
  • left: engage in active life
  • right: maximize physical & mental abilities
  • Goal: maximize physical and mental ability
  • Critiques:
    1. Doesn’t take into account people who have had a disability over their whole life and how they adapted
    2. Doesn’t take into account the social structure (ie. childhood SES and income)
    3. Missed policies and structures and issues of income
    4. Doesn’t look too much on the psychological aspects of aging (this is more physical health and cognition - thinking)
  • This is too individualistic - victim blaming
67
Q

health and retirement sturdy definition

A
  • no major diseases
  • no limitations in ADL
  • ability to preform variety of tasks
  • telephone based cognitive assessment
68
Q

WHO definition of active aging

A
  • WHO uses the term “ACTIVE AGING”
  • They’ve used more social determinant
  • This is personal and social as well
  • Holistic approach
69
Q

define primary aging

A
  • senescence
  • progressive decline in physical function due to increasing age
  • “normal”
  • from biological and physical perspective
  • negative connotation that things will go downhill
70
Q

define secondary aging

A
  • deterioration that is mediated by either disease or harmful environment/lifestyle factors
  • disease: disease is what causes the health to decline
  • harmful environment/lifestyle factors: always being in the sun and smoking a lot (2 biggest factors to make you look physically older)
71
Q

defining age changes (5)

A

must be:

  1. universal: all experience the same changes
  2. intrinsic: not necessarily due to environment, rather genetics
  3. progressive: getting worse
  4. irreversible: you can slow it down but it will happen
  5. deleterious: leads to a loss of function
72
Q

height: why do we become shorter?

A
  • cumulative effects of gravity on the spine (esp. discs)
  • musculoskeletal changes:
    loss of bone material in vertebrae –> weakening of vertebrae –> spine collapses and shortens
  • osteoporosis
  • poor posture
  • gradual change
73
Q

age related changes in the muscles

A
  • fat-free mass (FFM) decreases
  • BMI increases
  • muscle strength diminishes, but exercise can help
  • loss of muscle mass with age:
    1. Basal metabolic rate (# calories burn at rest) slows with age
    2. Fewer calories are needed
    3. Sarcopenia: loss of skeletal muscle mass
  • May be due to age or factors like decreased activity
  • Major risk factors for falls
  • Loss of muscles –> greater portion of fat
  • weight loss in older adults can be due to a loss of muscle not fat
74
Q

Isometric versus isotonic contractions

A
  • energy requirements (from most energy to least
    1. concentric
    2. isometric - no major age related changes
    3. eccentric - no major age related changes
  • strength in lower body decreases faster than the strength in the upper body
75
Q

age related changes to the bone, osteoporosis and osteopenia

A
  • reduction in bone strength and mass makes bones more susceptible to fractures (esp. for older women)
  • The rate of bone building is not keeping up to the rate of bone break down (out of sync)
  • osteopenia: lesser degree of bone loss
  • osteoporosis: more porous in the bone so great chance for bone breakage
76
Q

age related changes in the joints: cartilage changes

A
  1. cartilage:
    - surfaces become rougher in point areas
    - water content in cartilage decreased (restricts flexibility)
  2. change in cartilage may be due to:
    - wear and tear (use it too much so it breaks down)
    - internal process (sedimentary people also have a problem)
77
Q

cardiovascular changes: structural changes - 6 (increase vs. decrease)

A
  • heart size DOESNT change with age
    1. increase in fatty tissue
    2. decrease in efficiency in heart muscle’s ability to contract
    3. decrease in max heart rate during heavy exercise
    4. decrease in stroke volume
    5. decrease in ejection fraction
    6. decrease in oxygen uptake or consumption
78
Q

cardiovascular changes: functional changes (5)

A
  1. longer recovery: heart needs long rest period between beats
  2. decline in cardiac output: less O2 delivered to body
  3. changes in arteries and vein: increase rigidity (become less flexible)
  4. heart works harder to move blood to body –> increase BP
  5. slower venous return to heart –> stagnation of venous blood, varicose veins and clots in veins
79
Q

age related changes in respiratory sys (6)

A
  1. loss of strength in muscles involved in inhaling/exhaling
  2. increased stiffness of chest wall
  3. lungs:
    - smaller
    - flabbier
    - decrease in weight
    - lungs have less elastic recoil
    - decrease in vital capacity
    - increase in residual volume
  4. rigid increases
  5. blood vessels: more fibrous, less elastic
    - pulmonary artery: thicker, larger
    - implications:
    a. less blood flow to the lungs
    b. more pressure in the pulmonary artery
  6. alveoli:
    - walls get thinner
    - fewer blood capillaries available for gas exchange
    - surface area decreases by up to 20% (reduces max O2 uptake by as much as 55% by age 85)
    Implications:
    a. Increased levels of CO2 and decreased levels of O2 in the blood –>
    less O2 to vital organs –> respiratory conditions, sleep disorders
80
Q

age related changes in the urinary sys: structural changes in kidneys (3)

A
  1. blood vessels: smaller thicker – reduce blood flow through kidneys and decrease GFR
  2. ureter, bladder and urethra = lose elasticity and muscle tone (in competed emptying of bladder –> increased post-void residual)
  3. decline in bladder capacity –> less urine is stored in bladder … which causes:
    a. more frequent urination (esp. at night)
    b. signal to urinate may be delayed until bladder is almost full (causes incontinence)
81
Q

Benign Prostatic Hyperplasia (BPH)

A
  • nonmalignant enlargement of the prostate gland
  • may compress the urethra which goes through the centre of the prostate
    impede urine flow from the bladder through
    the urethra to the outside
  • Implication:
    –> urine: back up in the bladder (retention) –> need to
    urinate frequently during the day and night
  • for middle aged men aged 50 and older
82
Q

urinary incontinence: what is it and what are the 2 types? How can you train your muscles?

A
  • involuntary passing of urine in quantities that constitute a social/health problem
  • major reason why people get moved to a nursing home
  • older adults not likely to report this
  • NOT NORMAL PART OF AGING
    1. Chronic: stress incontinence:
  • involuntary passage of urine: laugh, cough, sneeze or during exercise
  • cause: weakened muscles in the external sphincter/pelvic floor, increased intra-abdominal pressure
  • affects women under age 60, men after prostate surgery
    2. urge incontinence
  • cant delay voiding the perception that the bladder is full; sudden need to urinate and may even leak urine
  • causes: may be due to UTO or to CNS impairment following a stroke
  • detrusor instability, internal sphincter weakness
  • implications:
    a. Overactive bladder and loses large amounts of urine
    b. Accidents happen - day and night
    c. More urine passes compared with stress incontinence
  • train muscles using Kegel exercises or pelvic muscle training
83
Q

age related reproductive changes: females (7)

A
  1. occurrence od climacteric - menopause (ovulation gradually stops)
  2. vaginal walls: thinner, drier, less elastic, shrink
  3. sexual intercourse can be uncomfortable:
    - decreased blood flow and in the amount of vaginal lubrication that is produced
  4. increased time to arousal
  5. decreased recreation of estrogen:
    - ovaries decrease by 50% and weight
    - uterus decreases in size and weight
    - become more fibrous
    - contribute to bone weakening –> osteoporosis
  6. loss of elasticity:
    - ligaments supporting ovaries and uterus
    - skin: loses elasticity, amount of fat tissue in breasts decreases – loss of firmness and sagging of breasts and other body tissues
  7. muscle and glandular tone diminish
84
Q

age related reproductive changes: males

A
  1. fewer viable sperm are produced and motility of sperm decreases
  2. amount and consistency of the semen changes
  3. Andropause: decrease in testosterone lvls occur with age
  4. testes: less firm and smaller
  5. fertility still possible in older men:
    - erection less firm
    - longer/delayed/less firm time to ejaculation
    - lengthening refractory period
    - prostate enlargement – may compress the urethra and inhibit or prevent the flow of urine
85
Q

Erectile Dysfunction: what is it and how does an erection occur?

A
  • lack of ability to achieve pr maintain an erection adequate for satisfactory sexual functioning
  • erection: too soft, brief or cant achieve at all
  • increases with age but NOT part of normal aging
  • due to physiological conditions like diabetes, high BP, medications, smoking etc.
  • due to psychological factors like depression, anxiety, relationship problems, fear of failure or self-esteem
  • How does an erection occur?
    1. physical/mental stimulation
    2. nerves in brain send msg to genital nerves
    3. penile blood vessels dilate
    4. pressure of blood floe traps blood within corpora cavernous
    5. penis expands = erection
    • main cause of withdrawing from sexual activity
86
Q

parts of the eye affected by aging

A
  1. lens: visual accommodation - width of the lens increases by approx 50% by age 80
    - thicker and less elastic
    - denser (more opaque and yellow) – refractive ability is impaired, changes in colour vision
    - farsightedness: increases with age
    - reduced pliability of lens (hard to focus, hard to see objects up close) – contributes to presbyopia
87
Q

Cataracts: most common age-related disorder of the eye

A
  • cloudy, yellow opaque lens
  • interferes with light rays passing thro lens
  • NOT part of normal aging
88
Q

Age-related macular Degeneration (AMD)

A
  • destroys sharp, central vision
  • AMD affects the macula
    part of the eye that allows you to see fine detail
    located in the centre of the retina
  • AMD causes no pain (so ppl can have symptoms of it and not even know until it’s too late)
89
Q

Glaucoma

A
  • cause: buildup of intraocular eye pressure – damages retina and optic nerve –> blindness
  • slow progression (symptoms not noticeable)
  • contributing factors:
    1. family history
    2. diabetes
    3. some medications
90
Q

age-related changes in hearing

A
  • presbycusis affects the ability to understand speech – cancer sounds but not discriminate words or comprehend what’s being said
  • hearing loss esp for high pitched sounds
  • cochlea and auditory nerve creates sound distortion
  • common form of sensorineural impairment
  • NORMAL part of aging
  • Possible causes: repeated exposure to loud/excess noises
91
Q

age related changes in hearing: consequence of hearing problems

A
  • social withdrawal
  • Mental health: isolated, depressed
  • Safety: cant hear alarms
  • Misunderstood conversations: paranoia, alienation, suspiciousness and disagreements
  • Labeled as confused or demented
  • Paranoid behaviour due to inappropriate actions based upon , missed info
92
Q

practical concerns: hearing - how can I recognize If someone cannot hear well?

A
  • Talk loudly
  • Turn their head so that their best hear is facing you
  • Blank look
  • Increased impatience in convo
  • Not reacting to loud noises
  • Withdrawal from social events
  • Ask people to repeat what was said
  • Respond inappropriately
93
Q

age-related changes in the skin senses

A
  • some loss of skin receptors
  • higher threshold of stimulation (less sensitive) in remaining receptors
  • safety implications:
    1. Burns: problem perceiving temperature
    2. Falls: receptors on soles of feet don’t function well
    3. Difficulty assessing how much pressure to exert - holding a glass or a fork
    worried about being clumsy –> avoid social situations
  • touch = mode of communication – can improve communication with older adults esp. those with verbal communication problems

** MOST LOSS IN HANDS AND FEET

94
Q

practical concerns: touch – how can I tell if a person has a poor sense of touch?

A
  • withdrawal or avoidance of activities usually enjoyed, such as sewing or playing with a pet
  • extremes in feeling pain (either not feeling pain or overreacting to slight pain)
  • showing no response to pressure
  • grasping objects tightly
