摘要
目的以体重增长值(⊿WAZ)在±0.67之间为依据研究4～12个月婴儿能量摄入、乳类摄入产能与其他食物产能比,分析其相关因素。方法以2004年11月-2005年3月重庆医科大学儿童医院儿童保健门诊就诊的4个月龄132名婴儿为研究对象,定期随访至12月龄。分 A 组(4～5月龄组)、B 组(6～8月龄组)、C 组(9～12月龄组)。两名专业人员负责体格测量。若⊿WAZ<-0.67则终止随访。食物称重与食物记录法计算每日食物摄入情况。结果各组婴儿体格发育良好,⊿WAZ 在-0.67～0.67时婴儿平均食物摄入量为119～128 g/(kg·d);A、B、C 组平均蛋白质摄入量分别为1.82、2.76、3.52 g/(kg·d);乳类摄入分别是总能量的93%、64%、56%;平均乳类摄入量为750～900 g/d;平均能量摄入分别为83.9、81.6、85.8 kcal/(kg·d),接近世界卫生组织2003标准,低于中国营养学会推荐值;能量密度为0.6～0.8 kcal/g。多元线性回归分析结果显示食物摄入量、能量密度是影响能量摄入的主要因素。结论 (1)本组4～12月龄婴儿能量摄人为82～86kcal/(kg·d)时婴儿体格发育正常;(2)4～12月龄婴儿期乳类摄入量达750～900 g/d可满足婴儿大部分能量、蛋白质需要;(3)食物摄入量和能量密度是影响婴儿能量摄入的两个最重要因素;婴儿食物能量密度以0.6～0.8 kcal/g为宜。
Objective To investigate the total energy intake, the energy from milk and other foods in the infants aged 4 to 12 months and analyze the factors related to the energy intake. Methods Totally 132 infants aged 4 months, who were brought for serial measurements to the Department of Primary Child Care, from November 2004 to March 2005 were enrolled into this study and were serially followed up until 12 months of age. The infants were divided into 3 groups, group A, age 4-5 months; group B, age 6-8 months; group C, age 9-12 months. The weights and the recumbent body lengths were measured by two professional staff members. The assessment of physical growth of the infants was done by using the CDC2000 reference. As the changes of Z score on weight for age （△WAZ） were 〈 - 0. 67 during the two visits, the participation of the infants to this study was discontinued. The dietary intakes of the infants were calculated according to 24 h dietary records or after weighing foods for sequential 3 days, Results （ 1 ） When the △WAZs of the participated infants were between 0. 67 and - 0. 67, the food intakes among three groups were 119-128 g/（kg·d）, the protein intakes were 1.82 g/（kg·d）, 2. 76 g/（kg·d） and 3. 52 g/（kg·d）, respectively. The milk intakes were 76-114 g/（kg·d）, which accounted for 93% of energy intakes in group A, 64% in group B and 56% in group C. The energy intakes of the 3 groups were 83.9 kcal/（kg·d）, 81.6 kcal/（kg·d）, and 85.8 kcal/（kg·d）, respectively, which were almost similar to WHO 2003 recommendations, and lower than that of Chinese RNL （2） The data from multiple linear regression analysis showed that the food intakes and the energy density were the most important factors related to energy intakes. The energy density of all foods was 0. 6-0.8 kcal/g. Conclusions （ 1 ） The growth of the infants was within the normal range as the energy intakes were 82-86 kcal/（kg·d）. （2） The infants may need 900-750 g/d of milk to meet the basic requirements of energy and protein. （3） The food intakes and the energy density were the most important factors related to the energy intakes, the appropriate energy density for infants is 0. 6-0. 8 kcal/g.
