Polygyny as a Predictor of Child Mortality

一夫多妻制是儿童死亡率的预测因素

基本信息

项目摘要

Among the Dogon of Mali, West Africa, 20% of children die in their first year of life and nearly 50% do not survive to age five years. A preliminary study of the causes of this mortality toll has shown that children (N = 176) are significantly more likely to survive if their parents and close paternal relatives are monogamously rather than polygamously married. The goals of this project are twofold: (1) to verify that marital status remains a predictor of child survivorship in a larger sample of over 1000 children, age 0 to 5 years, each of whom will be prospectively monitored for at least two years, and (2) to test alternative explanations for the causes of the relationship between family structure and child mortality. These explanations focus on differences in paternal investment in children, competition among co-wives, the dilution of resources in polygamous families, and the status of women. The results of this study will have practical significance for the problem of child mortality in SubSaharan Africa. They may also help inform other studies of children in poverty.
在西非马里的多贡人中,20% 的儿童在一岁内死亡,近 50% 的儿童活不到五岁。 对造成这一死亡人数原因的初步研究表明,如果父母和父系近亲实行一夫一妻制而不是一夫多妻制,儿童(N = 176)的存活率明显更高。 该项目的目标有两个:(1) 在 1000 多名 0 至 5 岁儿童的更大样本中验证婚姻状况仍然是儿童存活率的预测因素,每个儿童都将被前瞻性监测至少两年;(2) 测试家庭结构与儿童死亡率之间关系原因的替代解释。 这些解释集中在父亲对孩子的投资差异、妻子之间的竞争、一夫多妻制家庭的资源稀释以及妇女地位等方面。 这项研究的结果对于解决撒哈拉以南非洲地区的儿童死亡率问题具有实际意义。 它们还可能有助于为其他有关贫困儿童的研究提供信息。
