为了确定日本儿童的估计能量需求，需要使用双标记水 (DLW) 方法测量的总能量消耗 (TEE) 数据。本研究的目的是 1) 获得使用 DLW (TEEDLW) 测量的日本儿童的基本 TEE 数据，2) 将 TEEDLW 与通过各种估计公式估计的 TEE 进行比较，以计算其准确性，以及 3) 开发一个新的方程，使用身体成分和计步器来估计 TEE。使用 DLW 对 56 名 10 至 12 岁的日本儿童（33 名男孩，23 名女孩）进行了 TEE 测量。体力活动水平 (PAL) 的计算方法为 TEEDLW 除以估计的静息能量消耗。为了评估他们的身体活动，参与者在 7 天的 DLW 期间佩戴计步器。体内总水分由2H和18O计算；然后测定去脂质量（FFM）和脂肪质量（FM）。在正常体重的男孩和女孩中，TEEDLW 分别为 2067±230 kcal/d 和 1830±262 kcal/d。平均 PAL 为 1.58±0.17。 FFM 与 TEE 密切相关（r = 0.702，p < 0.01）。调整 FFM 和 FM 后，步数与 TEE 显着相关（r = 0.707，p < 0.01）。美国和加拿大的膳食参考摄入量 (DRI) 中使用的 TEE 估算公式对男女的 TEEDLW 进行了高精度估算（偏差：2.0%）。我们开发了由 FFM 和步数组成的新 TEE 方程，分别占男孩和女孩 TEE 方差的 68% 和 65%：男孩，47.1 × FFM (kg) + 0.0568 × 步数（步/天）– 122，女孩，55.5 × FFM (kg) + 0.0315 × 步数（步/天）- 117. 与目前的日本 DRI 相比，使用 DLW 测量的 10 至 12 岁日本儿童的 TEE，男孩大约低 7%，女孩大约低 12%。如果能够准确确定 PAL，那么美国和加拿大 DRI 中的公式可能适用于日本儿童。此外，可以使用 FFM 和步数来预测 TEE。
To establish Japanese children’s estimated energy requirements, total energy expenditure (TEE) data measured using the doubly labeled water (DLW) method is needed. This study aimed to 1) obtain basic TEE data from Japanese children measured using DLW (TEEDLW), 2) compare TEEDLW with TEE estimated by various estimation formulas to calculate their accuracy, and 3) develop a new equation to estimate TEE using body composition and pedometers. TEE was measured using DLW in 56 10- to 12-year-old Japanese children (33 boys, 23 girls). Physical activity level (PAL) was calculated by dividing TEEDLW by estimated resting energy expenditure. To assess their physical activity, participants wore pedometers during the 7-d DLW period. Total body water was calculated from 2H and 18O; fat-free mass (FFM) and fat mass (FM) were then determined. In boys and girls of normal weight, TEEDLW was 2067 ± 230 kcal/d and 1830 ± 262 kcal/d, respectively. Average PAL was 1.58 ± 0.17. FFM was strongly related to TEE (r = 0.702, p < 0.01). After adjusting for FFM and FM, step count was significantly associated with TEE (r = 0.707, p < 0.01). The TEE estimation formula used in the Dietary Reference Intakes (DRI) for the United States and Canada estimated TEEDLW with high accuracy (bias: 2.0%) in both sexes. We developed new equations for TEE consisting of FFM and step count, which accounted for 68% and 65% of TEE variance in boys and girls, respectively: boys, 47.1 × FFM (kg) + 0.0568 × step count (steps/d) – 122, and girls, 55.5 × FFM (kg) + 0.0315 × step count (steps/d) - 117. The TEE in 10- to 12-year-old Japanese children measured using DLW was approximately 7% lower for boys and 12% lower for girls compared to the current Japanese DRI. If PAL can be accurately determined, the equation in the DRI for the United States and Canada may be applicable to Japanese children. In addition, TEE could be predicted using FFM and step count.
