Anthropometric measurements are widely used to reliably quantify body composition and to estimate risks of overweight in healthy subjects and in patients. However, information about the reliability of anthropometric measurements in subjects with severe intellectual and sensory disabilities is lacking.
The purpose of this study was to determine the feasibility and the test-retest reliability of body composition measures in subjects with severe intellectual and sensory disabilities.
The study population consisted of 45 subjects with severe intellectual and sensory disabilities. Body mass index, waist circumference, skin folds and tibia length were measured. Reliability was assessed by Wilcoxon signed rank test, limits of agreement (LOA) and intraclass correlation coefficients. The outcomes were compared with values provided by the World Health Organization.
There were no significant differences between test and retest (P < 0.05). For the skinfold measurements, however, the LOA was insufficient. Intraclass correlation coefficients for all variables, except skinfold measurements, were 0.90 or above.
Test-retest reliability and feasibility for all measurements are acceptable in subjects with severe intellectual and sensory disabilities. Skinfold measurements, however, could not be reliably performed in these subjects. Measuring tibia length and using the determined formula to calculate body height from tibia length is a reliable alternative for measuring body height. Although measuring the body height of subjects with severe disabilities was feasible, measuring tibia length was more feasible.
人体测量广泛用于可靠地量化身体成分，并估计健康受试者和患者超重的风险。然而，缺乏关于严重智力和感官残疾受试者人体测量可靠性的信息。
本研究的目的是确定严重智力和感官残疾受试者身体成分测量的可行性和重测可靠性。
研究人群包括45名严重智力和感官残疾受试者。测量了体重指数、腰围、皮褶厚度和胫骨长度。通过Wilcoxon符号秩检验、一致性界限（LOA）和组内相关系数评估可靠性。将结果与世界卫生组织提供的值进行比较。
测试和重测之间无显著差异（P<0.05）。然而，对于皮褶厚度测量，一致性界限不足。除皮褶厚度测量外，所有变量的组内相关系数均为0.90或以上。
严重智力和感官残疾受试者所有测量的重测可靠性和可行性均可接受。然而，这些受试者无法可靠地进行皮褶厚度测量。测量胫骨长度并使用确定的公式从胫骨长度计算身高是测量身高的可靠替代方法。虽然测量严重残疾受试者的身高是可行的，但测量胫骨长度更可行。
