title: The Lee Obesity Index vindicated?
abstract: Correlations are reported for rats between the Lee Obesity Index and percent body fat. At weaning, rats were divided into 4 groups; supermarket diet and ovariectomy, supermarket diet and sham surgery. Lab Chow pellets and ovariectomy, and Lab Chow pellets and sham surgery. Four other groups received the treatments as adults. Eighteen and fifteen weeks later, respectively, the rats were measured for Obesity Index and were sacrificed for carcass analysis. The Obesity Index correlated well with percent body fat for animals made obese by diet; but it was not generally reliable for ovariectomized rats or for pellet fed sham operated controls. The Percent body fat also correlated well with body weight and with a simple weight/length ratio for rats made obese by diet. Thus, while the Obesity Index can reliably predict percent body fat, it may be no better at doing this than are some simpler measures.
