在慢性脊髓损伤（SCI）中，个体经历饮食不足，并受到未充分研究的研究领域的影响。我们的目标是评估（1）估计能量需求（EER）和估计能量摄入量（EEI）的方法之间的一致性和（2）膳食蛋白质摄入量是否符合SCI特定蛋白质指南。慢性SCI患者（n = 43）完成了3天的食物记录，以评估EEI和膳食蛋白质摄入量。EER采用Long和Institute of Medicine（IOM）方法和SCI特异性Farkas方法测定。蛋白质需要量计算为0.8 - 1.0 g/kg体重/d。报告的准确性和偏差进行了计算，并与身体成分。与IOM和Long法比较，SCI法没有高估EEI（P = 0.200）。与Long（94.8%，-5.24%）和IOM（64.1%，-35.4%）方法相比，SCI特定方法的报告准确性和偏差最好（98.9%，-1.12%）。体重（r =-0statist403）、体重指数（r =-0statist323）和总脂肪量（r =-0statist346）与IOM报告偏倚相关（均P <0.05）。BW与SCI特异性偏倚和Long报告偏倚相关（r =-0statist313，P = 0.041）。7名（16%）参与者符合BW特异性蛋白质指南。膳食蛋白质摄入量对体重的回归分析表明，各变量之间无相关性（β = 0.067，P = 0.730）。相反，体重每增加1 kg，总蛋白质摄入量和所需蛋白质摄入量之间的增量下降0.833 g（P = 0.0001）。EER的SCI特异性方法与EEI的一致性最好。蛋白质摄入量随着体重的增加而减少，与慢性SCI的蛋白质需求相反。
In chronic spinal cord injury (SCI), individuals experience dietary inadequacies complicated by an understudied research area. Our objectives were to assess (1) the agreement between methods of estimating energy requirement (EER) and estimated energy intake (EEI) and (2) whether dietary protein intake met SCI-specific protein guidelines. Persons with chronic SCI (n = 43) completed 3-day food records to assess EEI and dietary protein intake. EER was determined with the Long and Institute of Medicine (IOM) methods and the SCI-specific Farkas method. Protein requirements were calculated as 0·8–1·0 g/kg of body weight (BW)/d. Reporting accuracy and bias were calculated and correlated to body composition. Compared with IOM and Long methods (P < 0·05), the SCI-specific method did not overestimate the EEI (P = 0·200). Reporting accuracy and bias were best for SCI-specific (98·9 %, −1·12 %) compared with Long (94·8 %, −5·24 %) and IOM (64·1 %, −35·4 %) methods. BW (r = –0·403), BMI (r = –0·323) and total fat mass (r = –0·346) correlated with the IOM reporting bias (all, P < 0·05). BW correlated with the SCI-specific and Long reporting bias (r = –0·313, P = 0·041). Seven (16 %) participants met BW-specific protein guidelines. The regression of dietary protein intake on BW demonstrated no association between the variables (β = 0·067, P = 0·730). In contrast, for every 1 kg increase in BW, the delta between total and required protein intake decreased by 0·833 g (P = 0·0001). The SCI-specific method for EER had the best agreement with the EEI. Protein intake decreased with increasing BW, contrary to protein requirements for chronic SCI.
