Previous issue date: 2016-08-05 / The aim of this study was to evaluate the nutritional status and make a correlation between the use of different assessment protocols most commonly used, compared with DEXA (Dual-energy X-ray absorptiometry) in children and teenagers with Down syndrome (DS) . The sample comprised 41 children and adolescents from both gender, aged between 9 and 19 years old, being 26 with DS from ???Espa??o ConViv??ncias??? Project and 15 volunteers without DS rated as control group (CG). Anthropometric measurements of height, weight, waist circumference and hip, BMI (Body Mass Index) and skinfold thickness were made, and to calculate the the body fat %G it was used four protocols and DEXA. Blood samples were taken for biochemical analysis also applying if you recall 24 hours food intake and the isometric strength test. It was observed that 40% of the control group showed overweight and obesity while in the DS group was detected the rate of overweight and obesity was 50%. The caloric intake in both groups was according to the daily recommendations, but protein intake was above recommended on both groups. The stature, strength and reason force had a significant difference P <0.05 corroborating previous studies where people with Down syndrome have a lower height and strength when compared to the general population. In biochemical analyzes significant changes were shown (P <0.05) to triiodothyronine (T3) between the GC and SD. It was observed that in the DS group in Jackson and Pollock protocol ICC (0.83), r (0.82) and R?? (0.86) and Slaugter ICC protocol (0.74), r (0.79) R2 (0.62) wherein the linear regression analysis indicated that most explanatory power with equation was followed by Jackson and Pollock et al Slaugter. The group with DS showed lower isometric strength when compared to the CG and predisposition to being overweight and even obesity, a problem that can be worsened by poor eating habits. It was concluded that the equations of Slaughter et al would be the most appropriate to determine the %G in children and teenagers with DS by requiring less knowledge from appraiser to perform it, because of the amount folds to be analyzed, requiring less time for implementation and readiness access to the folds. It was noticed, finally, that because this is the first Brazilian study on this subject, there is a need for further studies related to the prediction of body composition in children and teenagers with DS that could promote the development of a specific equation for this audience. / O objetivo desse trabalho foi avaliar o estado nutricional e fazer uma correla????o do uso dos diferentes protocolos de avalia????o da composi????o corporal mais utilizados, comparados com a absometria de raio-X de dupla energia ??? DEXA, em crian??as e adolescentes com S??ndrome de Down (SD). A amostra foi constitu??da 41 crian??as e adolescentes de ambos os sexos, com idade entre 9 e 19 anos, sendo 26 (com SD do Projeto Espa??o Com-Viv??ncias e 15 volunt??rios sem SD classificados como grupo controle (GC). Foram feitas medidas antropom??tricas de estatura, peso, circunfer??ncia de cintura e de quadril, IMC, dobras cut??neas e, para calcular o %G utilizou-se quatro protocolos e o DEXA. Foram realizadas coletas de sangue para an??lises bioqu??micas, aplicando-se ainda o recordat??rio de consumo alimentar de 24 horas e o teste de for??a isom??trica. Foi observado que 40% do GC apresentaram sobrepeso e obesidade enquanto no grupo com SD a taxa de sobrepeso e obesidade foi de 50%. A ingesta cal??rica nos dois grupos esteve de acordo com as recomenda????es di??rias, por??m o consumo de prote??nas esteve acima do recomendado para ambos os grupos. A estatura, for??a e raz??o for??a tiveram uma diferen??a significativa P<0,05 corroborando com estudos anteriores onde pessoas com SD apresentam menor estatura e for??a quando comparadas ?? popula????o em geral. Nas an??lises bioqu??micas foram apresentadas altera????es significativas (P<0,05) para triiodotironina (T3) entre o GC e SD. Foi observado que no grupo SD no protocolo de Jackson e Pollock ICC(0,83), r(0,82) e R??(0,86) e no protocolo de Slaugter ICC(0,74), r(0,79), R2(0,62) sendo que a an??lise de regress??o linear indicou que a equa????o com maior poder explicativo foi a Jackson e Pollock seguida de Slaugter et al. O grupo com SD apresentou menor for??a isom??trica quando comparado ao GC e predisposi????o a ter peso excessivo e at?? mesmo obesidade, problema que pode ser agravado pelos h??bitos alimentares inadequados. Concluiu-se que as equa????es de Slaughter et al seria a mais adequada para determinar o %G em crian??as e adolescentes com SD, por exigir uma menor capacita????o do avaliador para executa-la, pela quantidade menor de dobras a serem analisadas, demandando menor tempo para execu????o e facilidade de acesso as dobras.
Percebeu-se, por fim, que por este ser o primeiro estudo brasileiro sobre este tema, h?? necessidade de novos estudos relacionados ?? predi????o de composi????o corporal de crian??as e adolescentes com SD que poderiam promover o desenvolvimento de uma equa????o espec??fica para este p??blico.
