This study was observational analytic with cross sectional approach. The samples were 120 young adults at the University of Jember, divided into 4 groups of BMI i.e. thin, normal, overweight, and obese.

The average percentage of the hand surface area on male 0.757%, female 0.702%, thin group 0.794%, normal 0.747%, overweight 0.704%, and obese 0.677%. Test analysis between men and women obtained significance value <0.05 while between groups of BMI obtained significance value <0.05 except between overweight and obese.
