Feeding practices have been analyzed prospectively in a sample of 1,112 healthy infants selected from families using an HMO. Data were collected at well-child visits during the first year of life regarding breast-feeding, formula feeding, and use of solid foods and cow's milk. Seventy percent of all infants were breast-fed, with the mean duration of breast-feeding being almost 7 months. Factors positively associated with breast-feeding included education and marriage, whereas maternal employment outside the home and ethnicity (being Hispanic rather than Anglo-American) were related to bottle feeding. Solid foods were introduced earlier by Hispanics and, also, among less well educated and single women; maternal employment was unrelated to the introduction of solid foods. Multiple regression analysis indicated different patterns for the two ethnic groups: education and employment were related to almost all feeding practices for Anglo-Americans, whereas education and employment predicted few feeding practices for the Hispanics. These findings suggest that the effects of ethnicity are independent of those of education.
在一个从使用健康维护组织（HMO）的家庭中选取的1112名健康婴儿样本中，对喂养方式进行了前瞻性分析。在婴儿出生后的第一年，通过健康儿童访视收集了有关母乳喂养、配方奶喂养、固体食物和牛奶使用情况的数据。所有婴儿中有70%进行母乳喂养，母乳喂养的平均时长将近7个月。与母乳喂养呈正相关的因素包括教育程度和婚姻状况，而母亲外出工作和种族（西班牙裔而非英裔美国人）与奶瓶喂养有关。西班牙裔婴儿更早开始添加固体食物，受教育程度较低的单身女性也是如此；母亲就业与固体食物的添加无关。多元回归分析表明两个种族群体的模式不同：教育程度和就业与英裔美国人几乎所有的喂养方式都有关，而教育程度和就业对西班牙裔婴儿喂养方式的预测作用较小。这些发现表明，种族的影响独立于教育程度的影响。
