There has been little research on women who have fewer than their ideal number of children toward the end of their childbearing years in low and middle-income countries (LMICs). We examine the level and distribution of unrealized fertility in LMICs across three geographical regions. We also examine the role of sex preference and other factors associated with unrealized fertility.
We used Demographic and Health Survey (DHS) data for women age 44-48 in 36 countries from the three geographical regions of Western and Central Africa, Eastern and Southern Africa, and South and Southeast Asia. We conducted descriptive analysis to examine the distribution of unwanted fertility and unrealized fertility, and fit adjusted logistic regressions of unrealized fertility. The main variables are number of living children (including by sex) and the sex composition of children. Other variables included education, marital status, age at first childbirth, wealth quintile, place of residence, exposure to family planning messages, contraceptive use, and country.
Unrealized fertility was highest in Western and Central Africa, followed by Eastern and Southern Africa. In all regions, there was a decrease in unrealized fertility with an increasing number of children. Findings for sex preference varied with little sex preference in the African regions, and some limited evidence of preference for sons in South and Southeast Asia. In most regions, higher levels of education, higher wealth quintile, and use of contraceptive methods were associated with decreased unrealized fertility.
Family planning programs and messages should consider regional and socioeconomic differences in unrealized fertility in order to give women and families the right to achieve the family size they desire regardless of their status.
在中低收入国家(LMICs),针对生育末期生育子女数少于理想子女数的女性的研究较少。我们研究了三个地理区域的 LMICs 中未实现生育的水平和分布。我们还研究了性别偏好和与未实现生育相关的其他因素的作用。
我们使用了来自三个地理区域(西非和中非、东非和南非以及南亚和东南亚)的 36 个国家中年龄在 44-48 岁的女性的人口与健康调查(DHS)数据。我们进行了描述性分析,以检查不想要的生育和未实现生育的分布,并拟合了调整后的逻辑回归模型来预测未实现生育。主要变量是活产子女数(包括性别)和子女的性别构成。其他变量包括教育程度、婚姻状况、初育年龄、财富五分位数、居住地、计划生育信息的接触情况、避孕方法的使用情况和国家。
未实现生育在西非和中非最高,其次是东非和南非。在所有地区,随着子女数量的增加,未实现生育的比例都有所下降。性别偏好的发现因非洲地区的性别偏好较小而有所不同,而在南亚和东南亚则有一些对儿子的偏好的有限证据。在大多数地区,较高的教育水平、较高的财富五分位数和避孕方法的使用与未实现生育的减少有关。
计划生育方案和信息应考虑未实现生育的地区和社会经济差异,以便让妇女和家庭有权实现他们期望的家庭规模,而不论其地位如何。
