Breast-feeding is the focus of rapidly growing interest. Research on the determinants of breast-feeding is only beginning. The research in this paper is based on World Fertility Survey data for Sri Lanka. We develop what we believe to be an appropriate probit model and find that there are significant socioeconomic factors that influence breast-feeding, in addition to the demographic factors focused upon in the literature. Moreover, some of them have clear policy implications, which are elaborated herein with respect to labor force, education, family planning and internal migration policies. In the course of the paper we also address a number of generally neglected statistical issues that should be considered in analyzing the determinants of breast-feeding, including problems resulting from digit preference or age heaping, the need to use dichotomous dependent variables, unavoidable truncation biases in the basic data, and structural shifts in the determinants of breast-feeding at different durations.
母乳喂养正成为迅速增长的关注焦点。关于母乳喂养决定因素的研究才刚刚起步。本文的研究基于斯里兰卡的世界生育率调查数据。我们构建了一个自认为合适的概率单位模型，发现除了文献中关注的人口因素外，还有显著的社会经济因素会影响母乳喂养。此外，其中一些因素具有明确的政策含义，本文将就劳动力、教育、计划生育和国内移民政策进行阐述。在本文中，我们还讨论了一些在分析母乳喂养决定因素时通常被忽视的统计问题，包括数字偏好或年龄堆积导致的问题、使用二分因变量的必要性、基础数据中不可避免的截断偏差，以及不同时间段母乳喂养决定因素的结构变化。
