This study investigates the effect of both total and unsupplemented breast-feeding in conjunction with birth interval on early childhood mortality, using longitudinal data from Matlab, Bangladesh. A discrete hazard model approach shows that it is not the duration of total breast-feeding but the duration of unsupplemented breast-feeding which increases child survival. Unsupplemented breast-feeding appears as such as crucial determinant of early childhood mortality that its effect could not be substantially attenuated even when important demographic and socioeconomic factors were controlled. Each of the covariates--supplementation, previous birth interval and onset of a subsequent conception--has an independent influence on early childhood mortality.
本研究利用来自孟加拉国马特莱的纵向数据，调查了纯母乳喂养和未添加辅食的母乳喂养与生育间隔相结合对幼儿死亡率的影响。一种离散风险模型方法表明，增加儿童存活率的并非纯母乳喂养的时长，而是未添加辅食的母乳喂养的时长。未添加辅食的母乳喂养似乎是幼儿死亡率的关键决定因素，即便在控制了重要的人口统计学和社会经济因素后，其影响仍无法大幅减弱。每个协变量——辅食添加、上次生育间隔和下次受孕开始——都对幼儿死亡率有独立影响。
