Zusammenfassung: | The aim of this study was to assess body composition and anthropometry of the elderly with regard to agreement between methods, development and validation of predictive equations and cutoffs. We evaluated 132 elderly patients (52 men and 80 women) aged between 60 and 91 years, users of primary health care, not institutionalized and drawn at random in proportion to the nine health districts of Goiânia, GO. For collection of anthropometric measurements, bioelectrical impedance (BIA) and dual energy x-ray absorptiometry (DEXA), standardized procedures were used by trained examiners and equipment was calibrated regularly. Analyses were performed using STATA/SE. Descriptive analysis, tests for comparison of means, equation validation according to criteria suggested by Lohman, Bland-Altman and Lin graphic analysis and ROC (receiver operator characteristic curve) analysis were carried out. The project was approved by the Ethics Committee of the Federal University of Goias. The Durnin and Womersley equation showed the highest concordance correlation coefficient (CCC = 0.846) and the lowest mean differences (MD = - 2.335) for males. The equations of Lean et al. (for men) and Deurenberg et al. (for women) showed the highest correlation with and lowest mean differences from DEXA. Equations were proposed to estimate body fat percentage (BF%): (males: BF% = - 16.868 + 0.571TSF + 0.409WC and females: BF% = 8.634 + 0.601BMI + 0.321SISF + 0.234SSSF + 0.398TSF 0.467BSF). In both sexes, the equations are similar to DEXA in estimating BF% with high precision and accuracy. In males, the proposed body mass index (BMI) cutoff point was ≥ 25 kg/m2; the waist circumference (WC) cutoff point was ≥ 98.9 cm. In women, the BMI and WC values with the most sensitivity, specificity and accuracy were ≥ 26.6 kg/m2 and ≥ 90.5 cm. Since the currently available equations for predicting body composition of elderly have certain limitations, these newly developed and validated equations for the two sexes can be recommended for wide use. Accurate BMI and WC cutoff points for predicting BF% in older adults were also identified. |

Foram avaliados 132 idosos (52 homens e 80 mulheres), com idade entre 60 e 91 anos, usuários da atenção primária à saúde, não instituicionalizados, selecionados a partir de sorteio aleatório proporcional aos nove distritos sanitários de Goiânia-GO. Para coleta de medidas antropométricas, impedância bioelétrica (BIA) e absortometria por raio-X de dupla energia (DEXA) foram utilizados procedimentos padronizados, por avaliadores devidamente treinados, com equipamentos regularmente calibrados. As análises foram realizadas no STATA/SE. Realizou-se análise descritiva, testes para comparação de médias, validação de equações segundo critérios sugeridos por Lohman, análise gráfica por Bland e Altman e por Lin e análise de Curva ROC (receiver operator characteristic curve). O projeto foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de Goiás. A equação de Durnin e Womersley apresentou maior coeficiente de correlação de concordância (CCC = 0,846) e menor diferenças médias (DM = - 2,335) para o sexo masculino. A equação de Lean et al. (para homens) e de Deurenberg et al. (para mulheres) apresentaram maior concordância e menores diferenças médias com DEXA. Foram propostas equações para estimativa do percentual de gordura corporal (%GC): (sexo masculino: %GC = - 16,868 + 0,571DCTR + 0,409CC e sexo feminino: %GC = 8,634 + 0,601IMC + 0,321DCSI + 0,234DCSE + 0,398DCTR 0,467DCBI). Em ambos os sexos, as equações propostas apresentaram semelhança com DEXA na estimativa do %GC, apresentando alta precisão e acurácia. No sexo masculino o ponto de corte proposto para índice de massa corporal (IMC) foi ≥ 25 Kg/m2 e para circunferência da cintura (CC) ≥ 98,9 cm. Nas mulheres os valores de IMC e CC com maior sensibilidade, especificidade e acurácia foram ≥ 26,6 Kg/m2 e ≥ 90,5 cm. As equações atualmentes disponíveis para predizer a composição corporal de idosos apresentam limitações, sendo desenvolvida e validada nova equação para ambos os sexos a qual recomenda-se sua ampla utilização. Identificou-se ainda pontos de corte acurados de IMC e CC para predizer %GC em idosos.application/pdfhttp://repositorio.bc.ufg.br/TEDE/retrieve/4373/Tese%20Larissa%20Silva%20Barbosa.pdf.jpgporUniversidade Federal de GoiásDoutorado em Ciencias da SaudeUFGBRCiencias da SaudeComposição corporalIdosoAntropometriaImpedância elétricaAbsortometria por raio-X de dulpa energiaEstudos de ValidaçãoÍndice de massa corporalCircunferência da cinturaPregas cutâneas1.Composição corporal; 2.Antropometria; 3.Idosos; 4.Estudos de Validação; 5.EpidemiologiaBody compositionAgedAnthropometryElectric impedanceDual-Energy X-Ray AbsorptiometryValidation studiesBody mass indexCNPQ::CIENCIAS DA SAUDEComposição corporal e antropometria de idosos:concordância entre métodos, desenvolvimento e validação de equações preditivas e pontos de corteBody composition and anthropometry of the elderly:agreement between methods, development and validation of predictive equations and cutoffs.info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFGinstname:Universidade Federal de Goiás (UFG)instacron:UFGORIGINALTese Larissa Silva Barbosa.pdfapplication/pdf4706638http://repositorio.bc.ufg.br/tede/bitstreams/5af2027c-9526-4207-bf25-8c4ca55d0895/download84142955db2151a63ddb14705543d0e3MD51TEXTTese Larissa Silva Barbosa.pdf.txtTese Larissa Silva Barbosa.pdf.txtExtracted Texttext/plain417138http://repositorio.bc.ufg.br/tede/bitstreams/b758be7f-dd49-4319-b2fa-ce22399a8dc1/downloadab09c20042abc4cf8c94bf6ea0c7a683MD52THUMBNAILTese Larissa Silva Barbosa.pdf.jpgTese Larissa Silva Barbosa.pdf.jpgGenerated Thumbnailimage/jpeg2944http://repositorio.bc.ufg.br/tede/bitstreams/6bd4351e-b53d-4d37-a378-ca7746dbb9cc/download88dc4e822e3a6fc323e1cb9cb10e7539MD53tde/15152014-07-30 03:13:40.009open.accessoai:repositorio.bc.ufg.br:tde/1515http://repositorio.bc.ufg.br/tedeRepositório InstitucionalPUBhttps://repositorio.bc.ufg.br/tedeserver/oai/requestgrt.bc@ufg.bropendoar:oai:repositorio.bc.ufg.br:tede/12342014-07-30T06:13:40Repositório Institucional da UFG - Universidade Federal de Goiás (UFG) |
