Abstract

BACKGROUND

The London Summit on Family Planning in 2012 inspired the Family Planning 2020 (FP2020) initiative and the 120×20 goal of having an additional 120 million women and adolescent girls become users of modern contraceptives in 69 of the world's poorest countries by the year 2020. Working towards achieving 120 × 20 is crucial for ultimately achieving the Sustainable Development Goals of universal access and satisfying demand for reproductive health. Thus, a performance assessment is required to determine countries' progress.

METHODS

An updated version of the Family Planning Estimation Tool (FPET) was used to construct estimates and projections of the modern contraceptive prevalence rate (mCPR), unmet need for, and demand satisfied with modern methods of contraception among women of reproductive age who are married or in a union in the focus countries of the FP2020 initiative. We assessed current levels of family planning indicators and changes between 2012 and 2017. A counterfactual analysis was used to assess if recent levels of mCPR exceeded pre-FP2020 expectations.

FINDINGS

In 2017, the mCPR among women of reproductive age who are married or in a union in the FP2020 focus countries was 45·7% (95% uncertainty interval [UI] 42·4-49·1), unmet need for modern methods was 21·6% (19·7-23·9), and the demand satisfied with modern methods was 67·9% (64·4-71·1). Between 2012 and 2017 the number of women of reproductive age who are married or in a union who use modern methods increased by 28·8 million (95% UI 5·8-52·5). At the regional level, Asia has seen the mCPR among women of reproductive age who are married or in a union grow from 51·0% (95% UI 48·5-53·4) to 51·8% (47·3-56·5) between 2012 and 2017, which is slow growth, particularly when compared with a change from 23·9% (22·9-25·0) to 28·5% (26·8-30·2) across Africa. At the country level, based on a counterfactual analysis, we found that 61% of the countries that have made a commitment to FP2020 exceeded pre-FP2020 expectations for modern contraceptive use. Country success stories include rapid increases in Kenya, Mozambique, Malawi, Lesotho, Sierra Leone, Liberia, and Chad relative to what was expected in 2012.

INTERPRETATION

Whereas the estimate of additional users up to 2017 for women of reproductive age who are married or in a union would suggest that the 120 × 20 goal for all women is overly ambitious, the aggregate outcomes mask the diversity in progress at the country level. We identified countries with accelerated progress, that provide inspiration and guidance on how to increase the use of family planning and inform future efforts, especially in countries where progress has been poor.

摘要

背景

2012 年伦敦计划生育峰会激发了计划生育 2020 倡议(FP2020)和 120×20 目标,即在 2020 年之前,使世界上最贫困的 69 个国家中的另外 1.2 亿名妇女和少女成为现代避孕药具的使用者。努力实现 120×20 对于最终实现普及生殖健康服务和满足生殖健康需求的可持续发展目标至关重要。因此,需要进行绩效评估以确定各国的进展情况。

方法

使用经过更新的计划生育估计工具(FPET)来构建 2020 年计划生育倡议重点国家中已婚或处于伴侣关系中的育龄妇女的现代避孕普及率(mCPR)、未满足的避孕需求和对现代避孕方法的需求满足率的估计数和预测数。我们评估了当前计划生育指标的水平以及 2012 年至 2017 年之间的变化情况。使用反事实分析来评估最近的 mCPR 是否超过了 FP2020 之前的预期。

结果

2017 年,2020 年计划生育倡议重点国家中已婚或处于伴侣关系中的育龄妇女的 mCPR 为 45.7%(95%置信区间[UI]为 42.4-49.1),未满足的现代避孕需求为 21.6%(19.7-23.9),现代避孕方法的需求满足率为 67.9%(64.4-71.1)。2012 年至 2017 年期间,已婚或处于伴侣关系中的育龄妇女使用现代避孕方法的人数增加了 2880 万人(95%UI 为 5.8-52.5)。在区域层面,亚洲已婚或处于伴侣关系中的育龄妇女的 mCPR 从 2012 年的 51.0%(95%UI 为 48.5-53.4)增长到 51.8%(47.3-56.5),增长缓慢,特别是与非洲从 23.9%(22.9-25.0)增长到 28.5%(26.8-30.2)相比。在国家层面,根据反事实分析,我们发现,已有 61%承诺实现 FP2020 的国家超出了 FP2020 之前对现代避孕药具使用的预期。肯尼亚、莫桑比克、马拉维、莱索托、塞拉利昂、利比里亚和乍得等国的快速增长相对 2012 年的预期有所增加,这是成功的例子。

解释

尽管截至 2017 年已婚或处于伴侣关系中的育龄妇女新增使用者的估计数表明,所有妇女的 120×20 目标过于雄心勃勃,但总体结果掩盖了国家层面进展情况的多样性。我们确定了进展加速的国家,这些国家提供了有关如何增加计划生育使用的灵感和指导,并为未来的努力提供了信息,尤其是在进展不佳的国家。
