作者通过检查1997-1998年儿童健康研究中收集的2,566名儿童的横截面数据，调查了儿童肺功能与水果、蔬菜、果汁和维生素A、C和E摄入量之间的关系。维生素C总摄入量低（小于或等于第10百分位数）与男孩和女孩的用力肺活量不足有关，女孩的血流量不足更大（1秒用力呼气量（FEV 1）为-3.3%，95%可信区间（CI）为-6.0，-0.5;用力呼气流量在用力肺活量的25%和75%之间（FEF 25 -75），-5.5%，95%CI：-10.5，-0.3）与男孩（FEV 1，-2.3%，95%CI：-4.8，0.3; FEF 25 -75，-2.4%，95%CI：-7.4，2.8）相比。膳食维生素E摄入量低与FEF 25 -75较低相关（男孩：FEF 25 -75，-8.9%，95%CI：-14.2，-3.3;女孩：FEF 25 -75，-2.5%，95%CI：-8.3，3.7）。FEF 25 -75缺陷与女孩的低膳食维生素A摄入量（FEF 25 -75，-7.9%，95%CI：-12.7，-2.8）和哮喘男孩的低总维生素A摄入量（FEF 25 -75，-15.6%，95%CI：-27.6，-1.6）相关。橙子和其他果汁是维生素C的最大来源，摄入量低与男孩的用力肺活量和FEV 1不足有关。总之，膳食抗氧化维生素摄入不足的儿童肺功能水平较低。
The authors investigated the relation between children's pulmonary function and intake of fruits, vegetables, juices, and vitamins A, C, and E by examining cross-sectional data from 2,566 children in the Children's Health Study collected during 1997-1998. Low total vitamin C intake (less than or equal to10th percentile) was associated with deficits in forced vital capacity for both boys and girls and with deficits in flows that were larger in girls (forced expiratory volume in 1 second (FEV1), -3.3%, 95% confidence interval (CI): -6.0, -0.5; forced expiratory flow between 25% and 75% of forced vital capacity (FEF25-75), -5.5%, 95% CI: -10.5, -0.3) compared with boys (FEV1, -2.3%, 95% CI: -4.8, 0.3; FEF25-75, -2.4%, 95% CI: -7.4, 2.8). Low dietary vitamin E intake was associated with lower FEF25-75 (boys: FEF25-75 , -8.9%, 95% CI: -14.2, -3.3; girls: FEF25-75 , -2.5%, 95% CI: -8.3, 3.7). Deficits in FEF25-75 were associated with low dietary vitamin A intake in girls (FEF25-75, -7.9%, 95% CI: -12.7, -2.8) and with low total vitamin A intake in boys with asthma (FEF25-75, -15.6%, 95% CI: -27.6, -1.6). Low intakes of orange and other fruit juices, which were the largest source of vitamin C, were associated with deficits in forced vital capacity and FEV1 in boys. In summary, lung function levels were lower in children with inadequate dietary antioxidant vitamin intake.
