5. Abdominal Analysis
Abdominal fatness is divided into subcutaneous type and visceral type. When it comes to body fat,
experts say that not only the amount of fat is important but also its distribution. If visceral fat area is
over 100 cm
2,
it is classified as "visceral obesity" regardless of P.B.F., W.H.R. or Body weight.
Waist-to-hip ratio (W.H.R.) shows the distribution of fat stored in one’s abdomen and hip. It is
simple but useful in assessing fat distribution. Body fat is stored in two distinct ways. They are often
categorized into and called 'apple' and 'pear' type. Apple type shows bigger girth of waist than hip
and pear type has bigger girth of hip than waist. If body fat in abdomen increases, the risk to
cardiovascular diseases, diabetes, etc. becomes higher.
1) W.H.R. (Waist to Hip Ratio)
W.H.R. is calculated by dividing waist girth by hip girth. When W.H.R. is below 0.9 (male) / 0.85
(female), the risk of visceral obesity is low.
2) Visceral Fat Level: The degree of visceral obesity is displayed in a level.
▪ Level 1~ 4 corresponds to subcutaneous fat type
▪ Level 5~ 8 corresponds to balanced type that subcutaneous and visceral fat is balanced.
▪ Level 9~10 corresponds to borderline type.
If subjects maintain current lifestyle, they will proceed to visceral fat type.
▪ Level 11~15 corresponds to visceral fat typeⅠ.
▪ Level 16~20 corresponds to visceral fat typeⅡ.
3) V.F.A. (Visceral Fat Area): The optimal range is 50 ~ 100 cm
2
(male), 40 ~ 80 cm
2
(female).
4) Abdominal circumference: Optimal range is <102cm/40inches (male), <88cm/35inches (female).
Abdominal Circumference is an estimated value in case of measure the navel circumference.
