1) The study compares body fat distribution between diabetic and non-diabetic persons aged 50-65 using the Conicity Index formula. 2) Diabetic persons, both male and female, had higher Conicity Index and WHR values, indicating more abdominal obesity compared to non-diabetic controls. 3) The Conicity Index was closely correlated with WHR for both diabetic and non-diabetic groups, suggesting it is a valid alternative to WHR for assessing abdominal fat distribution.

3. Background:
 It is well established that excess body fat around the abdomen is
related to several metabolic disorders and mainly to type-2 Diabetes
Mellitus (NIDDM).
 The most accurate technique for assessing abdominal fat mass, Axial
Computerized Tomography (ACT), is costly and time-consuming.
 Anthropometry could be a valid alternative to ACT for the evaluatin of
fat distribution. However, current anthropometric indicators of obesity
have several limitations.
 CONICITY INDEX implies that abdominal obesity is modelled as the
progression of a body from cylindrical shape toward the shape of 2 cones
with a common base at the waist level. This geometric approach expressed
with the formula: CONICITY INDEX = abdominal girth
0.109(weight/height)½
 With this new index, the abdominal girths of persons of the same
height and weight are referred to the same standard value for comparison.

4. Aim:
 To assess the Conicity Index values
in a group of NIDDM, aged 50-65
years, as compared to Controls.
 To study the correlation between
CONICITY INDEX and WHR
in NIDDM and Controls.

5. SUBJECTS & METHODS:
 Subjects: Age: 50 - 65 years.
86 Controls (53 males - 33 females) &
64 Type-2 Diabetics (33 males - 31 females).
 Measurements:
Weight, Height, Abdominal Girth,
Waist circumference, Hip circumference.
 Calculation:
1) BMI= Weight / Height2
2) WHR= Waist circumference / Hip circumference
3) CONICITY INDEX= Abdominal Girth
0.109* (Weight / Height)½

In persons aged 50-65 years:
 Women with NIDDM present
similar Body Fat Distribution,
as men with NIDDM.
 Conicity Index is
closely related to WHR.
