Background: This study was conducted to
develop a regression equation that accurately
estimates body fat percentage using relatively easy
and inexpensive method in adult obese korean
women.
Method: Data were collected among 500 obese
korean women visiting obesity clinic in Ewha
womans university Mokdong hospital, Seoul, Korea.
Height, weight, and circumferences at ten body sites
(neck, chest, waist, hip, thigh, calf, ankle, arm,
forearm, wrist) were measured as well as total body
bioelectrical impedance.
Results: The full regression equation estimates
body fat percentage included six variables: BMI,
forearm circumference, height, hip circumference,
thigh circumference. This equation accounted for
66.1% of the variance in body weight measured by
bioelectrical impedence, and their standard error of
estimate was 2.86%.
Conclusion: For the obese korean women in this
study, circumference measurements provided a
reletively good estimation of body fat percentage.
