26
Q

…… BMI is recommended for older adults

A

20-30

27
Q

inadequate protein intake can contribute to what in elderly

A

to muscle wasting (sarcopenia), weak bones, weakened immune system and delayed wound healing

28
Q

what are the factors involved with higher protein needs in older adults

A
  • anabolic resistance
  • low postprandial amino acid availability
  • decreased muscle perfusion
  • sarcopenia
  • disease related protein catabolism
29
Q

what are the factors involved in lower protein intake in older adults

A
  • genetic predisposition
  • physiological changes
  • medical changes
  • physical disability and mental disorders
  • socioeconomic conditions
30
Q

optimal intake of at least …….. protein is recommended in older adults, individual needs depend upon the severity of malnutrition risk

A

at least 1 to 1.5 g protein/kg BW/day

31
Q

in older adults regular exercise helps

maintain skeletal muscle strength and function in older adults

32
Q

in older adults, resistance training has

A

limited but positive effect on recovery of muscle in older people

33
Q

what is the recommendation for healthy muscle aging

A

a combination of resistance training and adequate dietary / amino acids intake for healthy muscle aging is recommended

34
Q

Older adults have greater protein needs to compensate for …… and …..

Older adults may also have decreased intake due to

A

Anabolic resistance
Hyper-metabolic disease

age-related appetite loss, medical condition, financial limits

35
Q

firstly it is important that older adults are getting enough protein, they may also see benefit from …

A

distributing their protein intake across all meals of the day

36
Q

what meal in elderly is most commonly low in protein

A

breakfast

37
Q

how is the gastrointestinal system affecting in elderly which influences nutrition

A
  • decreased saliva secretion
  • difficulty swallowing (dysphagia)
  • decreased secretion of hydrochloric acid and digestive enzymes
  • decreased vitamin B12 absorption
  • decreased peristalsis
38
Q

altered GI mobility in elderly can result in

A

constipation or diarrhoea

39
Q

why is there slower intestinal mobility in elderly people

A

intestinal wall losses strength and elasticity and hormonal secretions change

40
Q

what is atrophic gastritis

A

-Atrophy of the stomach mucosa resulting in reduced gastric acid, intrinsic factor and pepsin

41
Q

what needs intrinsic factor to be absorbed into the small intestine

A

vitamin B12

42
Q

atrophic gastritis can lead to what

A

can lead to vitamin B12 deficiency ( can take up to 3-6 years of poor absorption)

43
Q

what are the changes to the nervous system in older adults that influences nutrition

A
  • blunted appetite regulation
    -blunted thirst regulation
  • declining number of olfactory receptors, blood flow to nasal smell organ and increased thickness of nasal mucus
  • reduced nerve conduction velocity, affecting sense of smell, taste, touch, cognition
  • changed sleep at the wake cycle becomes shorter
44
Q

what is polypharamcy

A

use of multiple medications

45
Q

what are the two ways of getting medications

A

prescription medications (medicines ordered by a health professional)

over the counter medication

46
Q

what is the concern with polypharamcy and older adults

A

concern when they are taking multiple medications, who is monitoring what they are taking

47
Q

how many older adults are exposed to poly pharmacy approx

A

more than half

48
Q

older adults taking multiple medications tend to be

A
  • frail
  • experience greater weight loss
  • weakness
  • low activity
49
Q

medications may require dietary restrictions and can interfere with

A
  • appetite
  • digestion
  • metabolism
  • alterness
50
Q

what are the consequences of polypharamacy

A
  • drug - drug interactions increases
  • adverse drug interactions
  • adherence to medications declines
  • may increase renal impairment
