目标。我们的目标是描述婴儿喂养实践研究II(IFPS II)中使用的方法，这是一项关于婴儿出生第一年期间的喂养和护理实践的研究。调查主题包括母乳喂养、配方奶和补充喂养、婴儿健康、吸奶器的使用、食物过敏、睡眠安排、母亲的就业和儿童护理安排。此外，母亲的膳食摄入量在产前和产后进行了测量。IFPS II的样本来自一个由50万户家庭组成的全国分布的消费者意见小组。所有调查问卷均以邮寄方式发放，产前1份，产后10份。合格标准被用来实现健康的足月儿和早产儿晚期单胎母亲的抽样目标。除了关于婴儿的问卷外，妇女在产前和类似于分娩后4个月时被发送一份饮食评估问卷；该问卷也被发送给既没有怀孕也没有产后的对照组成员。结果：4902名孕妇的样本开始了研究，类似于2000年一直持续到婴儿的第一年。不同问卷的回复率从63%到87%不等。与全国具有代表性的家庭成长调查样本中单身人士的成年母亲相比，IFPS II参与者的平均教育水平更高；年龄更大；更有可能是中等收入、白人和有工作的人；吸烟的可能性较小；其他孩子也更少。与2004年参加全国免疫调查的妇女相比，IFPS II的母亲更有可能母乳喂养和母乳喂养时间更长。结论IFPS II提供了一个有价值的数据库，因为它的样本量大，问卷频率高，涵盖了婴儿喂养突出的问题。
OBJECTIVE. Our goal is to describe the methods used in the Infant Feeding Practices Study II (IFPS II), a study of infant feeding and care practices throughout the first year of life. Survey topics included breastfeeding, formula and complementary feeding, infant health, breast-pump use, food allergies, sleeping arrangements, mother's employment, and child care arrangements. In addition, mothers' dietary intake was measured prenatally and postnatally.PARTICIPANTS AND METHODS. The IFPS II sample was drawn from a nationally distributed consumer opinion panel of 500 000 households. All questionnaires were administered by mail, 1 prenatally and 10 postpartum. Qualifying criteria were used to achieve the sample goals of mothers of healthy term and late preterm singleton infants. In addition to the questionnaires about the infants, women were sent a diet-assessment questionnaire prenatally and at similar to 4 months after delivery; this questionnaire was also sent to members of a comparison group who were neither pregnant nor postpartum.RESULTS. A sample of 4902 pregnant women began the study, and similar to 2000 continued through their infant's first year. Response rates ranged from 63% to 87% for the different questionnaires. Compared with adult mothers of singletons from the nationally representative sample of the National Survey of Family Growth, IFPS II participants had a higher mean education level; were older; were more likely to be middle income, white, and employed; were less likely to smoke; and had fewer other children. Compared with women who participated in the National Immunization Survey who gave birth in 2004, IFPS II mothers were more likely to breastfeed and to breastfeed longer.CONCLUSIONS. The IFPS II provides a valuable database because of its large sample size, the frequency of its questionnaires, and its wide coverage of issues salient to infant feeding.
