Is anthropometric assessment of muscularity during growth : estimating fat-free mass with 2 skinfold-thickness measurements superior to measuring midupper arm muscle area in healthy prepubertal children?
The FFM estimate proved to be the better predictor for muscularity in healthy prepubertal children and is on a par with UAMA during puberty. FFM can be recommended as a simple anthropometric method to assess nutritional status before puberty, at least in healthy children.
In patients with RA who are near remission, the amount of joint swelling appears to be more predictive of radiographic progression than the amount of CRP.
