Using data from the Cebu Longitudinal Health and Nutrition Survey, I disentangle the complex interrelationship between breast-feeding, postpartum amenorrhea, and choice of contraceptive method. I find evidence that women substitute breast-feeding for contraception. Further, endogeneity bias, if not controlled, would cause the relationship to be slightly overstated. In addition, the results suggest that although increased education and income result in decreased breast-feeding, any effect on fertility will be offset by changes in contraceptive use.
利用宿务纵向健康与营养调查的数据，我梳理出母乳喂养、产后闭经和避孕方法选择之间复杂的相互关系。我发现有证据表明女性用母乳喂养替代避孕。此外，内生性偏差若不加以控制，会导致这种关系被略微夸大。此外，结果表明，尽管教育和收入的增加会导致母乳喂养减少，但对生育率的任何影响都会被避孕措施使用的变化所抵消。
