Level 1 is the maximum acceptable waist circumference irrespective of the adult age and there should be no further weight gain.
Level 2 denotes obesity and requires weight management to reduce the risk of type 2 diabetes & CVS complications.
Is measured at the point of greatest circumference around hips & buttocks to the nearest 0.5 cm.
The subject should be standing and the measurer should squat beside him.
Both measurement should taken with a flexible, non-stretchable tape in close contact with the skin, but without indenting the soft tissue.
Interpretation of WHR
High risk WHR= >0.80 for females & >0.95 for males i.e. waist measurement >80% of hip measurement for women and >95% for men indicates central (upper body) obesity and is considered high risk for diabetes & CVS disorders.
A WHR below these cut-off levels is considered low risk.
ADVANTAGES OF ANTHROPOMETRY
Objective with high specificity & sensitivity
Measures many variables of nutritional significance (Ht, Wt, MAC, HC, skin fold thickness, waist & hip ratio & BMI).
Readings are numerical & gradable on standard growth charts
Readings are reproducible.
Non-expensive & need minimal training
Limitations of Anthropometry
Inter-observers errors in measurement
Limited nutritional diagnosis
Problems with reference standards, i.e. local versus international standards.
Arbitrary statistical cut-off levels for what considered as abnormal values.
Nutritional intake of humans is assessed by five different methods. These are:
