The dietary intake of cancer patients can affect their nutritional status.
To assess the dietary intake and nutritional status of head and neck cancer patients on radiotherapy.
24-hour recalls and anthropometric measures were taken during the first and third weeks of radiotherapy.
Of the 62 patients, significant reductions were found in arm muscle area (p = 0.001) and arm muscle circumference (p < 0.001), and 69% of patients had an average weight loss of 5.7% in three weeks. With regards to their dietary intake, reductions were found in energy (26.5 kcal/kg/d-21.3 kcal/kg/d, p < 0.001), carbohydrate (196.9 g/d - 180.5 g/d, p = 0.020), protein (1.19 g/kg/d-0.93 g/kg/d, p = 0.009) and fat (44.4 g/d-33.1 g/d, p < 0.001) intakes during the study period.
The changes that result from cancer radiotherapy led to reductions in dietary intake and negatively affected body composition measures.
癌症患者的饮食摄入会影响其营养状况。
评估头颈部癌症患者放疗期间的饮食摄入和营养状况。
在放疗的第一周和第三周进行24小时回顾调查和人体测量。
62例患者中，手臂肌肉面积（p = 0.001）和手臂肌肉周长（p < 0.001）显著减少，69%的患者在三周内平均体重减轻5.7%。在饮食摄入方面，研究期间能量摄入减少（从26.5千卡/千克/天降至21.3千卡/千克/天，p < 0.001），碳水化合物摄入减少（从196.9克/天降至180.5克/天，p = 0.020），蛋白质摄入减少（从1.19克/千克/天降至0.93克/千克/天，p = 0.009），脂肪摄入减少（从44.4克/天降至33.1克/天，p < 0.001）。
癌症放疗导致的变化致使饮食摄入减少，并对身体成分测量产生负面影响。
