The objective of this paper is to identify social and biomedical variables that influence the selection of methods of infant feeding in the United States and to provide guidelines for the choice of control variables in the design and interpretation of studies that examine the influence of breast-feeding on infant and child health. Data were drawn from a national household survey, the Child Health Supplement of the 1981 Health Interview Survey conducted by the National Center for Health Statistics. Relationships between demographic, socioeconomic, and health variables were studied for the total sample of children under age 5 y as well as for black and white women separately. The data provide evidence for the importance of both social and health variables as selection factors for breast-feeding in the United States.
本文的目的是确定影响美国婴儿喂养方式选择的社会和生物医学变量，并为在设计和解释研究母乳喂养对婴幼儿健康影响的研究时选择控制变量提供指导方针。数据取自一项全国家庭调查，即由国家卫生统计中心开展的1981年健康访谈调查的儿童健康补充调查。针对5岁以下儿童的总样本以及分别针对黑人和白人女性，研究了人口统计学、社会经济和健康变量之间的关系。这些数据证明了社会和健康变量作为美国母乳喂养选择因素的重要性。
