To determine the reliability of anthropometric and body composition measurements in children with special needs.
Observational study.
Specialist support schools (primary and secondary) in Manchester, UK.
53 children with moderate-to-severe learning disability; 30 non-standers (14 boys) and 23 standers (15 boys). Mean ages were 11 years (range 3-20) for non-standers and 12.4 years (range 8-19) for standers.
Anthropometric measures included: height/length, segmental measures, weight, skinfolds, body circumferences and body composition estimated from bioelectrical impedance analysis (BIA). These were measured twice, 2-4 weeks apart.
Reliability was assessed using the technical error of measurement (TEM).
The TEM for height and supine length was 0.55 cm for standers and 2.47 cm for non-standers, respectively. For non-standers, the TEMs for knee height and tibial length were 0.81 and 1.57 cm, respectively. The TEM for weight was 0.55 kg for standers and 0.75 kg for non-standers. For skinfold thickness, the TEM was smaller for non-standers than standers. The TEM for mid-upper arm circumference for standers and non-standers was 0.91 and 0.82 cm, respectively. The TEM for BIA in standers and non-standers was 34.7 and 54.1 Ω, respectively. Some measurements, including waist circumferences, were difficult to obtain reliably.
Anthropometric and body composition measurements were feasible to obtain in children with special needs. However, the reliability of these measures differs between non-standers and standers and should be considered when choosing appropriate measures.
确定特殊需求儿童的人体测量和身体成分测量的可靠性。
观察性研究。
英国曼彻斯特的专业支持学校（小学和中学）。
53 名中度至重度学习障碍儿童；30 名非站立者（14 名男孩）和 23 名站立者（15 名男孩）。非站立者的平均年龄为 11 岁（范围 3-20 岁），站立者的平均年龄为 12.4 岁（范围 8-19 岁）。
人体测量测量包括：身高/长度、分段测量、体重、皮褶、体围和通过生物电阻抗分析（BIA）估计的身体成分。这些测量进行了两次，间隔 2-4 周。
使用技术测量误差（TEM）评估可靠性。
站立者的身高和仰卧长度的 TEM 为 0.55cm，非站立者的 TEM 为 2.47cm。对于非站立者，膝高和胫骨长度的 TEM 分别为 0.81 和 1.57cm。站立者的体重 TEM 为 0.55kg，非站立者的 TEM 为 0.75kg。对于皮褶厚度，非站立者的 TEM 小于站立者。站立者和非站立者的上臂中部周长的 TEM 分别为 0.91 和 0.82cm。站立者和非站立者的 BIA 的 TEM 分别为 34.7 和 54.1Ω。一些测量，包括腰围，很难可靠地获得。
在特殊需求儿童中获得人体测量和身体成分测量是可行的。然而，这些测量的可靠性在站立者和非站立者之间存在差异，在选择适当的测量方法时应予以考虑。
