背景：虽然双能x线吸收仪（DXA）被认为是儿童肥胖最准确的测量方法，但很少用于检查婴儿喂养与儿童肥胖之间的关系。目的：目的是确定5岁时的肥胖是否与母乳喂养有关，与婴儿期引入辅食的时间有关，还是两者兼而有之。设计：采用DXA测量313名5岁儿童的身体成分。在孩子3岁时，从母亲那里获得了关于母乳喂养、配方奶喂养和引入辅食时间的数据。在调整瘦体重、性别、出生体重、母亲肥胖、种族和其他社会人口变量后，采用回归分析来检验婴儿喂养与脂肪量之间的关系。结果：53%的孩子是男孩，80%是白人，20%是黑人。母乳喂养组与未母乳喂养组的校正脂肪质量无显著差异((x) > bar +/- SE分别为4.48 +/- 0.09和4.76 +/- 0.17 kg；P = 0。17)。母乳喂养时间较长的儿童和没有同时进行配方奶喂养的儿童的脂肪量并没有明显低于从未母乳喂养的儿童。在4个月前和4个月后添加辅食的儿童在脂肪量上没有显著差异（分别为4.49 +/- 0.12和4.63 +/- 0.12 kg; P = 0.42）。结论：母乳喂养和引入辅食的时间与5岁时的肥胖无关。
Background: Although dual-energy X-ray absorptiometry (DXA) is considered the most accurate measure of adiposity in children, it has rarely been used to examine the relation between infant feeding and adiposity during childhood.Objective: The objective was to ascertain whether adiposity at age 5 y was related to breastfeeding, to the timing of the introduction of complementary foods during infancy, or to both.Design: Body composition was measured in 313 children at age 5 y by using DXA. Data on breastfeeding, formula feeding, and the timing of the introduction of complementary foods were obtained from the mothers when the children were 3 y old. Regression analysis was used to examine the relation between infant feeding and fat mass after adjustment for lean body mass, sex, birth weight, maternal obesity, race, and other sociodemographic variables.Results: Fifty-three percent of the children were boys, 80% were white, and 20% were black. There was no significant difference in adjusted fat mass between those ever breastfed and those never breastfed ((x) over bar +/- SE: 4.48 +/- 0.09 and 4.76 +/- 0.17 kg, respectively; P = 0. 17). Children who were breastfed for a longer duration and those who were breastfed without concurrent formula feeding did not have significantly lower fat mass than did those children who were never breastfed. Children did not differ significantly in fat mass if they were introduced to complementary foods before or after 4 mo of age (4.49 +/- 0.12 and 4.63 +/- 0.12 kg, respectively; P = 0.42).Conclusion: Neither breastfeeding nor the timing of the introduction of complementary foods was associated with adiposity at age 5 y.
