Body Composition In Females With 21-hydroxylase Deficiency: Comparison Of Anthropometric Methods And Bioelectric Impedance In Relation To A Control Group [composição Corporal Em Mulheres Com Deficiência Da 21-hidroxilase: Comparação Dos Métodos Antropométricos E De Impedância Bioelétrica Em Relação A Um Grupo Controle]

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.543274281Merke, D.P., Bornstein, S.R., Congenital adrenal hyperplasia (2005) Lancet, 365 (9477), pp. 2125-2136Riepe, F.G., Sippell, W.G., Recent advances
