Lumbar spine (L-2, L-3, L-4) bone mineral density was measured in 184
healthy boys and girls aged 5.00 through 11.99 years by dual photon
absorptiometry. Weight, height, age, triceps skinfold thickness, and midarm
circumference were also measured. Weight, height, and age were highly
correlated with bone mineral density. In the population studied, a
quadratic regression equation using body weight as the independent variable
best described bone mineral density: bone mineral density = 0.3209 +
[0.0168 (weight)] - [0.0001 (weight2)].
