Background: This study was to investigate a relationship among the balance abilities including dynamic balance, static length, and static area and the general demographic characteristics related to the obesity including age, height, weight and sex, waist circumference (WC) and waist hip ratio (WHR), and body mass index (BMI), which is most widely used.


This study was started in October, 2012 and was finished in June, 2013. A total of sixty-one healthy adults who resided in Seoul and Gyeonggi province were chosen in the convenience sampling method. We collected the waist and hips circumferences, the height and weight of the participants to understand the degree of obesity. Also, we measured the sum of each tilt angles of front, back, left and right sides for dynamic balance and measured the length and area of COP line for static balance using a balance device. The data was collected and analyzed using SPSS 18.0 statistical package program.

Normal group and obesity group was divided by measured WC and WHR values. The results showed that the dynamic balance (p<0.05) and the static length(p<0.01) were significantly different in both WC and WHR. Dynamic balance was estimated by the following model: Dynamic balance = 72.497-(0.048×age)-(16.681×height)+(0.586×weight)-(1.127×BMI)-(0.287×WC)-(8.621×WHR)-(0.516×sex) (male=0, female=1) (R2 =0.727, p<0.01).

Results: The WC was the only significant variable(p=0.005) in the dynamic balance model while the age being the only significant variable in static balance model.

Interpretation: In conclusion, WC and WHR was the most relevant method that distinguished the normal group from the obese group as it related to dynamic balance.  Also it was observed that the static balance ability decreased with aging.
