Given the high prevalence of malnutrition and potential impact nutritional status can have on a child undergoing treatment for cancer, it is vital that oncology centers regularly assess nutritional status. It is important that simple noninvasive anthropometric nutrition assessment measures correlate to more accurate body composition measures.
The aim of this study was to determine the relationship between anthropometric measures and percent body fat determined via air displacement plethysmography in the children being treated in a pediatric oncology and hematology department.
This cross-sectional study measured height, weight, percent ideal body weight (%IBW), mid arm circumference, triceps skinfolds, and mid upper arm fat area in 23 children. These anthropometric variables were compared against the reference measure of percent body fat via air displacement plethysmography.
Correlational analysis and general linear models showed that there was a significant statistical relationship between percent body fat and body mass index Z score, %IBW, mid arm circumference, triceps skinfolds, and arm fat area.
Simple anthropometric measurements of %IBW and triceps skinfolds are good indicators of percent body fat and should be incorporated into regular nutrition assessment of the pediatric oncology patient.
鉴于营养不良的高患病率以及营养状况对接受癌症治疗的儿童可能产生的潜在影响，肿瘤中心定期评估营养状况至关重要。重要的是，简单的非侵入性人体测量营养评估方法要与更准确的身体成分测量方法相关联。
本研究的目的是确定在儿科肿瘤血液科接受治疗的儿童中，人体测量指标与通过空气置换体积描记法测定的体脂百分比之间的关系。
这项横断面研究测量了23名儿童的身高、体重、理想体重百分比（%IBW）、上臂中部周长、三头肌皮褶厚度和上臂中部脂肪面积。将这些人体测量变量与通过空气置换体积描记法测定的体脂百分比参考指标进行比较。
相关性分析和一般线性模型表明，体脂百分比与体重指数Z评分、%IBW、上臂中部周长、三头肌皮褶厚度和上臂脂肪面积之间存在显著的统计学关系。
简单的人体测量指标如%IBW和三头肌皮褶厚度是体脂百分比的良好指标，应纳入儿科肿瘤患者的常规营养评估中。
