Define anthropometry
|
Measurement of body size, weight, and proportion
|
|
|
Purpose of anthropometry
|
To indicate health, development and growth. Evaluate nutritional status and monitor nutritional intervention.
|
|
|
Measuring body composition comprises of measuring what three things?
|
Adiposity (amount of fat) - total amount & distribution, lean body mass, and bone density
|
|
|
What is purpose of assessing growth?
|
Assess skeletal growth in children to measure overall health in children (most sensitive measure) and used to calculate other measures.
|
|
|
What are methods to measure total amounts versus lean body mass?
|
Underwater weighing/air displacement (Bod/Pod), skinfold, and bioelectric impedance
|
|
|
Head circumference-for-age is at excess and inadequate at what percentiles?
|
Inadequate at <5th percentile
Excess >95th percentile |
|
|
Stunting/shortness is a problem at what percentile?
|
<5th percentile
|
|
|
Underweight is a problem at what percentile for weight-for-length and BMI-for-age?
|
<5th percentile
|
|
|
Overweight is a problem for what percentile for weight for length and BMI-for-age?
|
weight for length ratio >95th
BMI for age >95th |
|
|
Risk of overweight is seen at what percentile?
|
Risk of overweight 85-95th percentile: BMI for age 85-95th percentile
|
|
|
What are methods to evaluate weight status?
|
Wrist ("quick and dirty"), elbow width, body height to wrist circumferance
|
|
|
What is the purpose of weight?
|
To assess under or over nutrition, assess growth in children, assess shifts in fluid status, used to calculate other measures, BMI, determine drug doses
|
|
|
Standards/Goals with weight?
|
"Where I feel good." Height-weight charts, rule of thumb, CDC weight charts-age specific weight standards
|
|
|
How do you calculate Rule of thumb for MEN?
|
Male: 5 feet gets 110 lbs and then
add 6 lbs/extra 1 in. |
|
|
How do you calculate rule of thumb for women?
|
Females: 5 feet gets 100 lbs and then add +5lbs/extra in.
|
|
|
What is the percentage of actual weight that is considered underweight, normal, overweight, and obese for IBW?
|
Underweight: <90% IBW
Normal Weight: 90-100% IBW Overweight: 110-120% Obese: >120% |
|
|
How do you calculate BMI?
|
Take weight (kg)/height (m^2)
|
|
|
What are the guidelines for BMI?
|
Underweight:<18.5
Normal: 18.5-24.9 Overweight: 25.0-29.9 Obesity: >30 |
|
|
Ways to measure adiposity?
|
Waist circumferance, waist to hip ratio, skin fold (tricep skinfold, and others), dual energy x-ray absorptometry (DEXA)
|
|
|
How to measure body composition?
|
Mid arm circumferance, calf-circumferance, midarm muscle area
|
|
|
Compare body circumference measures to bioelectrical impedence and BodPod?
|
Body circumference measurements need to be taken by a trained professional or are not very exact, Bioelectrical impedance is when sensing electrodes are placed on hands and current electrodes are places on the feet. BIA is higher than Bod/Pod.
|
|
|
What is the research or gold standard for measurements?
|
Underwater weighting and air displacement plethysmography
|
|
|
What are the limitations to the standard?
|
Fasting, limited exercise, various equations for different population
|
|
|
What is the point of waist to hip ratio?
|
Distribution of waist to hip ratio: Crude index of regional fat distribution: index of upper (android) vs. lower (gynoid) obesity
|
|
|
When is there an increased risk of CVD?
|
When waist to hip ratio is men >.9 and women >.8
|
