一项研究旨在评估营养干预研究的能量摄入（EI）。受试者为17名老年男性（年龄：72 ± 5岁）和11名老年女性（年龄：67 ± 4岁）。采用两种方法测量EI：4天饮食记录（DR组; n = 12）或饮食问卷（DQ组; n = 16）。受试者在干预期间根据此摄入量喂养3周，并用双标记水测量能量消耗（EE）以验证EI的结果。在第二周开始和第三周结束时测量体重和身体组成，代谢能（ME）计算为总能量摄入（GEI）减去粪便和尿液中的能量。DR组和DQ组的GEI、ME和EE无差异（GEI的平均值+/- SD：10.09 +/- 1.21和9.29 +/- 1.36; ME：9.09 +/- 1.28和8.34 +/- 1.31; EE：10.13 +/- 1.57和9.25 +/- 0.35 MJ/d）。两组ME均显著低于EE（DR组P < 0.05; DQ组P < 0.01）。在干预期间体重显著降低（DR组的平均值+/- SD：-0.64 +/- 0.50 kg，P < 0.001; DQ组：-0.86 +/- 0.90 kg，P < 0.01）。体重变化与能量平衡呈显著正相关（ME-EE; P < 0.05）.如身体组成测量结果所示，体重减轻是脂肪量的减少。（250字处删节）
A study was intended to estimate energy intake (EI) for a nutrition intervention study. Subjects were 17 elderly men (age: 72 +/- 5 years) and 11 elderly women (age: 67 +/- 4 years). Two methods were used to measure EI: a 4-day dietary record (DR group; n = 12) or a dietary questionnaire (DQ group; n = 16). Subjects were fed for 3 weeks according to this intake during an intervention period, and energy expenditure (EE) was measured with doubly labelled water to verify the resulting figure for EI. Body weight and body composition were measured at the beginning of the second week and at the end of the third week, and metabolizable energy (ME) was calculated as gross energy intake (GEI) minus energy in faeces and urine. GEI, ME and EE did not differ between the DR and DQ groups (mean +/- SD for GEI: 10.09 +/- 1.21 and 9.29 +/- 1.36; ME: 9.09 +/- 1.28 and 8.34 +/- 1.31; EE: 10.13 +/- 1.57 and 9.25 +/- 0.35 MJ/d). In both groups ME was significantly lower than EE (DR group P < 0.05; DQ group P < 0.01). Body weight decreased significantly during the intervention period (mean +/- SD for DR group: -0.64 +/- 0.50 kg, P < 0.001; DQ group: -0.86 +/- 0.90 kg, P < 0.01). The change in body weight was significantly correlated with energy balance (ME - EE; P < 0.05). As shown from the results of the body composition measurements, body weight loss was a decrease of fat mass.(ABSTRACT TRUNCATED AT 250 WORDS)
