The inaccuracy of resting energy expenditure (REE) prediction formulae to calculate energy metabolism in children may lead to either under- or overestimated real caloric needs with clinical consequences. The aim of this paper was to apply artificial neural networks algorithms (ANNs) to REE prediction. We enrolled 561 healthy children (2-17 years). Nutritional status was classified according to World Health Organization (WHO) criteria, and 113 were obese. REE was measured using indirect calorimetry and estimated with WHO, Harris-Benedict, Schofield, and Oxford formulae. The ANNs considered specific anthropometric data to model REE. The mean absolute error (mean ± SD) of the prediction was 95.8 ± 80.8 and was strongly correlated with REE values ( = 0.88). The performance of ANNs was higher in the subgroup of obese children (101 ± 91.8) with a lower grade of imprecision (5.4%). ANNs as a novel approach may give valuable information regarding energy requirements and weight management in children.
用于计算儿童能量代谢的静息能量消耗（REE）预测公式的不准确性，可能导致实际热量需求被低估或高估，从而产生临床后果。本文的目的是将人工神经网络算法（ANNs）应用于REE预测。我们招募了561名健康儿童（2至17岁）。根据世界卫生组织（WHO）标准对营养状况进行分类，其中113名儿童为肥胖。使用间接测热法测量REE，并通过WHO、哈里斯-本尼迪克特、斯科菲尔德和牛津公式进行估算。人工神经网络考虑特定人体测量数据来建立REE模型。预测的平均绝对误差（均值±标准差）为95.8±80.8，并且与REE值高度相关（=0.88）。在肥胖儿童亚组中，人工神经网络的表现更好（101±91.8），不精确程度较低（5.4%）。作为一种新方法，人工神经网络可能为儿童的能量需求和体重管理提供有价值的信息。
