This paper examines the extent to which the traditional practice of sexual abstinence during lactation has broken down among Yoruba women residents in urban areas. The first major finding is that there is a gradual erosion of the tradition, and the dominant factors of modernization are education of the woman and the use of contraception. The second major finding is that the breakdown of postpartum sexual taboos has statistically significant negative consequences on duration of lactation, although the negative impact of woman's education is greater. The third major finding is that duration of breastfeeding reduces birth interval significantly only when it is less than 15 months, and that both durations of breastfeeding and birth intervals have declined over time. The first two findings suggest further reductions in the proportion of women who abstain from sexual relations during lactation and in durations of breastfeeding as more women become more educated. Significant declines in birth intervals may follow soon after.
本文考察了城市地区居住的约鲁巴族女性中，哺乳期禁欲这一传统习俗的瓦解程度。第一个主要发现是，这一传统正在逐渐受到侵蚀，现代化的主要因素是女性受教育程度和避孕措施的使用。第二个主要发现是，产后性禁忌的破除对哺乳期时长具有统计学意义上的负面影响，尽管女性受教育程度的负面影响更大。第三个主要发现是，只有当母乳喂养时长少于15个月时，母乳喂养时长才会显著缩短生育间隔，并且随着时间推移，母乳喂养时长和生育间隔都有所下降。前两个发现表明，随着越来越多的女性受教育程度提高，哺乳期禁欲的女性比例和母乳喂养时长将进一步降低。生育间隔可能很快也会大幅下降。
