A considerable number of previous studies have examined the trends, correlates, and consequences of premarital childbearing among adolescents and young women in Africa. However, very little is known about whether and how soon single mothers have another premarital birth in sub-Saharan African countries. This study examines the timing of a second premarital birth among single mothers and assesses how it may differ across key socio-demographic variables.
We pooled recent Demographic and Health Surveys from 25 sub-Saharan African countries to create a database of 57, 219 single mothers aged 15-49 years. Cumulative incidence graphs and Fine and Gray's competing risk models were used to delineate the timing of a second premarital birth and its socio-demographic correlates.
More than one-third of single mothers in 16 countries have had a second premarital birth in their reproductive life. We also observed that more than 15% of the single mothers in Angola, Benin, the Republic of Chad, Liberia, Namibia, Nigeria, Sierra Leone, and Uganda, have had another premarital birth three years after the first. The incidence of a second premarital birth was significantly lower among women with secondary or higher education, compared to women with less than secondary education (p < 0.05) in most countries. Residence in an urban area compared to rural, was also significantly associated with a low incidence of second premarital birth in 10 countries (p < 0.05).
Findings indicate a rapid progression to having a second premarital birth in some sub-Sahara African countries, particularly among socio-economically disadvantaged women. The findings suggest the need for tailored interventions for improving the quality of life of single mothers, to reduce the associated burden and consequences of having a premarital birth.
先前有相当数量的研究考察了非洲青少年和年轻女性婚前生育的趋势、相关因素和后果。然而，对于撒哈拉以南非洲国家的单身母亲是否以及多快会再次发生婚前生育，知之甚少。本研究考察了单身母亲第二次婚前生育的时间，并评估了其在关键社会人口变量方面可能存在的差异。
我们汇集了来自撒哈拉以南非洲 25 个国家的最近的人口与健康调查数据，创建了一个数据库，其中包含 57219 名年龄在 15 至 49 岁之间的单身母亲。使用累积发生率图和 Fine 和 Gray 的竞争风险模型来描绘第二次婚前生育的时间及其社会人口学相关因素。
在 16 个国家中，超过三分之一的单身母亲在其生育期内已经有了第二次婚前生育。我们还观察到，在安哥拉、贝宁、乍得共和国、利比里亚、纳米比亚、尼日利亚、塞拉利昂和乌干达，超过 15%的单身母亲在第一次婚前生育后三年内又有了一次婚前生育。在大多数国家，与受过中学以下教育的女性相比，受过中学或更高教育的女性第二次婚前生育的发生率明显较低（p<0.05）。与农村地区相比，居住在城市地区也与 10 个国家（p<0.05）第二次婚前生育发生率较低显著相关。
研究结果表明，在一些撒哈拉以南非洲国家，尤其是在社会经济处于不利地位的女性中，第二次婚前生育的速度很快。研究结果表明，需要针对单身母亲制定有针对性的干预措施，以提高其生活质量，从而减轻婚前生育带来的相关负担和后果。
