Bottom Line: Results.Hip circumference had the strongest correlation with BMI (r = 0.89, P < 0.001) among the circumferences of individual body sites.An average body circumference strongly correlated with BMI in women and can serve as a surrogate of BMI.

ABSTRACT
Introduction. Significant correlations between BMI and some body circumferences have been previously reported. In this study we investigated if the average of the sum of eight body circumferences can be a substitute for BMI. Patients and Methods. BMI and eight body circumferences (neck, waist, hip, arm, forearm, wrist, thigh, and ankle) were measured in 193 apparently healthy women aged 20-83, and within a wide range of BMI. Women with BMI ≤ 24.9 were designated as normal, with BMI 25-29.9 as overweight and with BMI ≥ 30 as obese. The relationship of the average body circumference (ABC) of the sum of the eight circumferences, and of each individual circumference with BMI, was evaluated. Results. ABC had the strongest correlation with BMI (r = 0.95, P < 0.001) among all the circumferences tested. Hip circumference had the strongest correlation with BMI (r = 0.89, P < 0.001) among the circumferences of individual body sites. Receiver-Operator Characteristic analysis showed that women with ABC > 44.0 cm could be recognized as having BMI ≥ 25 with sensitivity 90.2% and specificity 88.5%, while women with ABC > 47.1 cm could be diagnosed as having BMI ≥ 30 with sensitivity 92.2% and specificity 91.5%. Conclusion. An average body circumference strongly correlated with BMI in women and can serve as a surrogate of BMI.

fig1: Linear regression of log ABC (average body circumference) on log BMI in the entire study population.

Mentions: The log transformed values of the BMI and ABC values in the entire study population showed normal distribution. Simple linear regression of log BMI on log ABC showed a strong correlation between these two parameters in the entire study population (r = 0.94, P < 0.001); the regression coefficient r2 = 0.89 implies that 89% of the variation of BMI may be explained by ABC (Figure 1). In order to adjust for age, log BMI was regressed simultaneously on log ABC and age whose distribution was not far from normal. Age did not significantly affect the effect of ABC on BMI (beta coefficient for ABC 0.93, and for age −0.09). Simple correlation of BMI with ABC (r = 0.95) was slightly higher when compared with that between BMI and UBC (r = 0.91) or that between BMI and LBC (r = 0.89) (Table 2). A similar trend was observed more or less in the three subgroups.
