Prospective, 3-year longitudinal dietary intakes of 25 prepubertal, pancreatic-insufficient children with cystic fibrosis (CF) and mild lung disease, and the intakes of 26 control children were compared, and relationships among energy intake, nutritional status, and pulmonary function were determined.
Intakes from 3-day weighed food records were compared with CF recommendations, recommended dietary allowances (RDA), and the recommendations of the Third National Health and Nutrition Examination Survey (NHANES III). Energy and nutrient intakes were analyzed by repeated-measures analysis of variance.
Children with CF consumed more energy than control children (p = 0.025) in terms of calories per day, percentage of RDA by age and by age and weight, energy adjusted for fat malabsorption, and percentage of NHANES III recommendations. Energy intake was similar between boys and girls with CF. The percentage of energy from fat was greater (p = 0.0004) in the CF group (3-year mean, 33%) than in the control group. Height and weight z scores declined in the CF group (p <0.05) with time. Vitamin and mineral intakes were generally adequate in the CF group.
The children in this sample did not consume the CF recommended intakes of 120% RDA for energy or a high-fat (40% of energy) diet. Energy intakes may be insufficient in this group to meet requirements for optimal growth.
比较25名青春期前胰腺功能不全且患有轻度肺部疾病的囊性纤维化（CF）儿童与26名对照儿童的前瞻性3年纵向饮食摄入量，并确定能量摄入、营养状况和肺功能之间的关系。
将3天称重食物记录的摄入量与CF推荐量、推荐膳食摄入量（RDA）以及第三次全国健康和营养检查调查（NHANES III）的建议进行比较。通过重复测量方差分析对能量和营养素摄入量进行分析。
就每日卡路里、按年龄和按年龄及体重计算的RDA百分比、针对脂肪吸收不良调整后的能量以及NHANES III建议的百分比而言，CF儿童比对照儿童消耗更多能量（p = 0.025）。CF男孩和女孩之间的能量摄入量相似。CF组中来自脂肪的能量百分比（3年平均值为33%）高于对照组（p = 0.0004）。CF组的身高和体重z评分随时间下降（p <0.05）。CF组的维生素和矿物质摄入量总体充足。
该样本中的儿童未达到CF推荐的能量摄入量，即RDA的120%，也未遵循高脂肪（占能量的40%）饮食。该组的能量摄入量可能不足以满足最佳生长的需求。
