Even though the total fertility rate (TFR) has decreased significantly over the past decades in many countries, it has remained stable in sub-Saharan African (SSA) countries. However, there is variation among the sub-regions and inhabitants of SSA. Therefore, this study aimed to conduct a meta-analysis of demographic and health surveys (DHS) to estimate the pooled level of TFR in SSA and to depict sub-regional and inhabitant differences.
The data source for this study was the standard Demographic and Health Survey datasets of 33 sub-Saharan African countries, accessed through www.meaasuredhs.com between 2010 and 2018. The point estimate of the total fertility rate with its corresponding standard error in each sub-Saharan African country was estimated using the R package. Using the point estimate of the TFR with the standard error of each country, the pooled estimate of the TFR was generated by the STATA command.
The study comprised 1,324,466 live births in total. The pooled estimate of sub-Saharan Africa's overall fertility rate was five children per woman (95% CI: 4.63-5.37). Consequently, the pooled estimate of total fertility for people living in urban and rural areas was 3.90 (95% CI: 3.60-4.21) and 5.82 (95% CI: 5.43-6.21) children per woman, respectively. In sub-group analysis, the pooled estimates of the TFR for the East African, Central African, Southern African, and West African regions, respectively, were 4.74, 5.59, 3.18, and 5.38 children per woman. Total fertility rates were greater in low-income nations (5.45), lower-middle-income countries (4.70), and high-middle-income countries (3.80).
SSA has a relatively high total fertility rate. The regions of West and Central Africa have the highest overall fertility rate. The fertility rate is higher in countries with a large rural population and low income. Strategies should be developed to address this public health concern, especially in rural Central and Western Africa.
尽管过去几十年来,许多国家的总和生育率(TFR)显著下降,但撒哈拉以南非洲(SSA)国家的总和生育率保持稳定。然而,SSA 的次区域和居民之间存在差异。因此,本研究旨在对人口与健康调查(DHS)进行荟萃分析,以估计 SSA 的总和生育率,并描绘次区域和居民差异。
本研究的数据来源是 2010 年至 2018 年期间通过 www.meaasuredhs.com 访问的 33 个撒哈拉以南非洲国家的标准人口与健康调查数据集。使用 R 包估算每个撒哈拉以南非洲国家的总和生育率的点估计值及其相应的标准误差。利用每个国家 TFR 的点估计值及其标准误差,通过 STATA 命令生成 TFR 的汇总估计值。
该研究共包括 1324466 例活产。撒哈拉以南非洲总生育率的汇总估计值为每名妇女 5 个孩子(95%CI:4.63-5.37)。因此,居住在城市和农村地区的人的总生育率汇总估计值分别为 3.90(95%CI:3.60-4.21)和 5.82(95%CI:5.43-6.21)个孩子。在亚组分析中,东非、中非、南非和西非地区的 TFR 汇总估计值分别为 4.74、5.59、3.18 和 5.38。低收入国家(5.45)、中低收入国家(4.70)和中高收入国家(3.80)的总生育率更高。
SSA 的总生育率相对较高。西非和中非地区的总和生育率最高。农村人口多、收入低的国家生育率较高。应制定策略来解决这一公共卫生问题,特别是在中非和西非农村地区。
