Abandonment of breast-feeding in parts of the world where contraception is not in common use may mean both higher birthrates and, especially among the poor, higher infant death rates. In this article estimates of the magnitude of these effects are made.
在世界上一些避孕措施并不普及的地区，放弃母乳喂养可能意味着更高的出生率，尤其是在贫困人口中，还意味着更高的婴儿死亡率。本文对这些影响的程度进行了估算。
