Identification of obesity in children and teenagers

Obesity is a condition that increases the risk of developing several health problems, resulting in high health care costs worldwide. Therefore, it is important to investigate several avenues for the control of this condition. This study aimed to identify a dermatoglyphical condition that distinguishes obesity individuals from those of appropriate weight.

The sample comprised 2172 children and teenagers between the ages of 10 and 19 years, female and male, from public and private schools of the municipality of Joaçaba, Santa Catarina, Brazil.

In a comparison of qualitative variables, i.e., patterns, significant differences were observed between groups, including a higher frequency of ulnar loops (LU) on the index and middle fingers (MET2 and MET3) in the appropriate weight group. In the obesity group, a greater frequency of whorls (W) on fingers MET2 and MET3 was observed in males. In females, there were statistically significant correlations between the presence of radial loops (LR) on MET3 in the appropriate weight group and arches (A) in the obesity group.

The study uncovered dermatoglyphical marks characteristic of obesity individuals.
