anthropometry ppt 5

anthropometry

study of human body measurements on a comparative basis

anthropometry involves (3)

body weight/stature, body composition, waist and hip circumference

higher hip/waist circumference is linked to

diabetes and heart disease

why is anthropometry important

establishes normative data & standards, assess the efficacy of treatments, determines impact of disease states

anthropometry measurements of infants up to 2 years

who growth charts, measure length, waist, head circumference, weight for length

anthropometry measurements of children age 3+

cdc growth charts, measure height, weight, bmi

measurement of length/height (knee height) infants 0-2 white boys

40.54 + (2.22 + KH)

measurement of length/height (knee height) infants 0-2 black boys

39.6 + (2.18 + KH)

measurement of length/height (knee height) infants 0-2 white girls

43.21 + (2.15 + KH)

measurement of length/height (knee height) infants 0-2 black girls

46.59 + (2.02 + KH)

abnormal measurement of frontal occipital circumference

greater than or equal to 2 standard deviations above or below the mean

measurement of height in children 3 yrs or older uses a

wall stadiometer

Abnormal stature of children 3+

greater than or equal to 2 standard deviations of the mean or 3rd percentile

weight-for-age cdc growth chart percentiles

mainly want patients to grow over a curve rather than focusing on a specific percentile

percentile meaning of weight-for-age infant cdc growth chart percentiles

___% of similarly aged infants weigh less than that infant

demispan

estimate an adult's stature using arm length

demispan differs by

gender

female demispan (stature) equation

Ht (cm) = (1.35 x demispan (cm)) = 60.1

male demispan (stature) equation

Ht (cm) = (1.4 x demispan (cm)) = 57.8

cons of demispan stature calc

standardized values might not be accurate for everyone, races/ethnicities that are not white/black, there are predictive equations so just predicts height doesn't actually measure it

pros of demispan stature calc

good for those with lower mobility issures

rank accuracy of ways to measure stature

1. demispan

2. knee height

3. ulnar length

female knee height calc for stature

Ht (cm) = 84.88 - (0.24 x age) + (1.83 x KH (cm))

male knee height calc for stature

Ht (cm) = 64.19 - (0.04 x age) + (2.02 x KH (cm))

female ulnar length calc for stature

Ht (cm) = 95.6 + (2.77 x ulnar length (cm))

male ulnar length calc for stature

Ht (cm) = 79.6 + (3.60 x UL (cm))
