Resumo: | Background: Body composition has been considering an important predictor parameter in different clinical and healthy promotion scenarios. Nevertheless, reference values from healthy community from young to the most advanced age?s samples with generalizable eligibility criteria from bioelectrical impedance equipment are lacking. The objective of this study was to estimates the percentile values of the body composition parameters for healthy individuals from both sexes through different ages. Methods: Cross-sectional study with healthy individuals from the community, older than five years, of both sexes. Body composition was assessed thought electrical bioimpedance. Body composition parameters assessed were: total body fat, percentage of total body fat, fat free mass, percentage of lean mass, fat mass index, and fat free mass index. The relationships of outcome variables (body composition variables) and predictor variable (age) were analyzed using a quantile regression model (5th to 95th). Results: A total of 1241 participants, with median and range age of 27.0 (5 to 99) years, 651 (52.5%) were female, and 777 (73%) Caucasian. Only fat free mass 25th percentile was not significantly associated with age. That is a tendency of increasing with the increase age of the percentage of corporal fat and the corporal index. The fat free mass index shows an increasing tendency from the child to the adult and decreasing from the elderly. Conclusion: The present study estimated the percentile values of the body composition parameters, evaluated through the electrical bioimpedance analysis, for a healthy population of different ethnicities. Age had an association with all parameters at most percentiles in both sexes. |

No entanto, os valores de refer?ncia de comunidades saud?veis de jovens at? idades mais avan?adas de amostras com crit?rios de elegibilidade generaliz?veis a partir da avalia??o por bioimped?ncia el?trica est?o faltando. O objetivo deste estudo foi estimar os valores percentuais dos par?metros de composi??o corporal para indiv?duos saud?veis de ambos os sexos em diferentes idades. M?todos: Estudo transversal com indiv?duos saud?veis da comunidade, com idade superior a cinco anos, de ambos os sexos. A composi??o corporal foi avaliada atrav?s da bioimped?ncia el?trica. Os par?metros de composi??o corporal avaliados foram: gordura corporal total, percentual de gordura corporal total, massa livre de gordura, percentual de massa magra, ?ndice de massa gorda e ?ndice de massa livre de gordura. As rela??es das vari?veis de resultado (vari?veis de composi??o corporal) e vari?vel preditor (idade) foram analisadas usando um modelo de regress?o quant?lica (5 a 95). Resultados: Um total de 1241 participantes, com mediana e faixa et?ria de 27,0 (5 a 99) anos, 651 (52,5%) eram do sexo feminino e 777 (73%) caucasianos. Apenas percentil 25% de massa livre de gordura n?o se associou significativamente com a idade. Essa ? uma tend?ncia que ocorre com o aumento da idade do percentual de gordura corporal e do ?ndice de gordura corporal. O ?ndice de massa livre de gordura mostra uma tend?ncia crescente da crian?a para o adulto e decrescente nos idosos. Conclus?o: O presente estudo estimou os valores percentuais dos par?metros de composi??o corporal, avaliados mediante da an?lise de bioimped?ncia el?trica, para uma popula??o saud?vel de diferentes faixas et?rias.Submitted by PPG Medicina e Ci?ncias da Sa?de (medicina-pg@pucrs.br) on 2019-07-09T11:35:54Z No. of bitstreams: 1 Marina_Azambuja_Amaral.pdf: 2106003 bytes, checksum: 4aaa39309a236b26dc2f4788cdecafa4 (MD5)Approved for entry into archive by Sheila Dias (sheila.dias@pucrs.br) on 2019-07-09T19:12:26Z (GMT) No. of bitstreams: 1 Marina_Azambuja_Amaral.pdf: 2106003 bytes, checksum: 4aaa39309a236b26dc2f4788cdecafa4 (MD5)Made available in DSpace on 2019-07-09T19:36:15Z (GMT).
