the state of a person health in term of the nutrients on his or her diet
there are 4 types of nutrition assessment ABCD:
Anthropometric: the science that defines physical measures of a person size, form, and functional capacities
Biochemical: blood/test , explore chemical processes related to living organism
biophysical: hair, eyes, nails, tongue
Clinical: clinical history and status of a person
-health history
-medical history
-social history
-medication
-socio economic -status
-food availability, accessibility
-knoledge and beliefs
Dietary: choose from various data collection tools to assess nutritional status
-24 hours recall
-3 days food record
-food frequency questionnaire(ffq)
-diet history
dietary assesment
make meaningful and accurate interpretation of data on food and drinks over an specific time
- conpare to CFG, food composition table, Canadians nutrient file,
nutritonal status - malnutrition
deficiencies or excesses in nutation intake, imbalance of essential nutrients
-undernutrition= insufficient intake of energy and nutrients that do not meets need of an individual to maintain good health
-over-nutrition= excess macro or macronutrients
difference between a nutrition assessment and nutritional screening?
nutritional screening determines risk of a problem
nutritional assessment determines presence of a problem
how do we evaluate body weight ?
BMI
Distribution fat
Body composition
body mass index (BMI) and how to calculate it ?
a measurement representing the body fat by to their height
weight (kg)/height(m)2
BMI values below 18.5 or above 30 have increase of risk heath problems
body composition
measurement of body fat and lean muscle mass
can be measurement by:
underwater weighing
skinfold measurement
bioelecritcal impedence analysis
bod pod
dual-energy x-ray absorptiometrical
distribution fat
Visceral fat(apple shape)
adipose tissue around abdominal organs
-more metabolically active
-associated with higher chronic desease risk
-upper body
Subcutaneous fat(pear shape) : adipose tissue under the skin ex: hips and legs
-no health risk
-lower body
basal metabolic rate( BMR)
energy expended to maintain basal, or resting, functions of the body
-60-70% of total energy expenditure
-more lean tissue increases your bmr
-bmr decrease with age, 3-5% per decade after 30
factor that increase bmr
-higher lean body mass
-greater height
-young age
-elevated levels of thyroid hormone
-stress,fever, illness
-male gender
-pregnancy and lactation
factors that decrease bmr
-lower lean body mass
-lower height
-older age
-depressed level of thyroid hormone
-starvation or fasting
-female gender
