GONCALVES, Ezequiel Moreira et al. Body composition in females with 21-hydroxylase deficiency: comparison of anthropometric methods and bioelectric impedance in relation to a control group. Arq Bras Endocrinol Metab [online]. 2010, vol.54, n.3, pp.274-281. ISSN 1677-9487.  http://dx.doi.org/10.1590/S0004-27302010000300005.

OBJECTIVE: To estimate body composition by evaluating skinfold thickness (ST) and electric bioimpedance (EB) in a group of women with congenital adrenal hyperplasia due to classical 21-hydroxylase deficiency (CAH-C-21OHD) in relation to a control group. SUBJECTS AND METHODS: Sixteen patients and 26 controls were evaluated, all female, with age varying from 8 to 18 years. Fat (FM) and lean (LM) masses were evaluated by ST and EB. FM and LM data were analyzed in relative (%) and absolute (kg) values, and in relation to stature (FMI and LMI). RESULTS: There were no observed significant differences between the two methods in each group. In relation to the control group, CAH-C-21OHD patients showed higher values for FM (%) EB, FMI EB and LMI ST but lower values for FM (%) EB. Positive and high correlation values were observed for all parameters analyzed. CONCLUSION: ST and EB results observed were similar in this sample of females with CAH-C-21OHD, but controversial in relation to the control group, suggesting caution when using these methods to evaluate body composition in this population.
