Über diese App

This app is designed for the calculation of Z-scores and percentiles for bone mineral content (BMC) and areal bone mineral density (aBMD) for children ages 5–20 years, as measured by dual-energy X-ray absorptiometry (DXA), for the following sites: total body, total-body-less-head, lumbar spine, total hip, femoral neck, and distal ⅓ radius. Separate calculations are available by age, by sex, and by race (Black and non-Black). Height-Z–adjusted Z-scores for these measures are also calculated. The BMC and aBMD data are derived from the Bone Mineral Density in Childhood Study [Zemel B et al., J Clin Endocrinol Metab 2011;96(10):3160–3169]. Calculations are also available for lumbar-spine bone mineral apparent density (BMAD) [Kindler JM et al. J Clin Endocrinol Metab 2019;104(4):1283–1292].

Neuerungen

Have added the ability to directly enter the age (years, months and days) instead of having to enter date of birth and date of measurement (which is still the default). Minor bug fixes and appearance tweaks. Have improved appearance of TitleBar.
