For an eating disorder study over a period of 1 year, we measured total-body bone mineral using a Hologic QDR 1000 W in a total of 157 subjects and observed anomalies that questioned the accuracy of such measurements. Using the recommended Enhanced software, a change in total bone mineral content (delta BMC) correlated positively with a change in weight (delta W; r = 0.66), but a loss of weight was associated with an increase in bone mineral areal density (BMD; r = 0.58), arising from a… CONTINUE READING
