The vast majority of adolescent births occur in low- and middle-income countries and are associated with negative outcomes for both the mother and her child. A multitude of risk factors may explain why few programs have been successful in delaying childbearing and suggest that multisectoral interventions may be necessary. This study examines the longer-term impact of a two-year (2015-17) multisectoral program on early sexual debut and fertility in an urban informal settlement in Kenya.
The study used a randomized trial design, longitudinally following 2,075 girls 11-14 years old in 2015 until 2019. The interventions included community dialogues on unequal gender norms and their consequences (violence prevention), a conditional cash transfer (education), health and life skills training (health), and financial literacy training and savings activities (wealth). Girls were randomized to one of four study arms: 1) violence prevention only (V-only); 2) V-only and education (VE); 3) VE and health (VEH); or 4) all four interventions (VEHW). We used ANCOVA to estimate intent-to-treat (ITT) impacts of each study arm and of pooled study arms VE, VEH, and VEHW relative to the V-only arm, on primary outcomes of fertility and herpes simplex virus-2 (HSV-2) infection, and secondary outcomes of education, health knowledge, and wealth creation. Post-hoc analysis was carried out on older girls who were 13-14-years-old at baseline. In 2018, in the VEHW arm, in-depth qualitative evaluation were carried out with adolescent girls, their parents, school staff, mentors, community conversation facilitators, and community gatekeepers. The trial is registered at ISRCTN: ISRCTN77455458.
At endline in the V-only study arm, 21.0 percent of girls reported having had sex, 7.7 percent having ever been pregnant and 6.6 percent having ever given birth, with higher rates for the older subsample at 32.5 percent, 11.8 percent, and 10.1 percent, respectively. In the full sample, ever having given birth was reduced by 2.3 percentage points (pp) in the VE and VEHW study arms, significant at 10 percent. For the older subsample there were larger and significant reductions in the percent ever having had sex (8.2 pp), HSV-2 prevalence (7.5 pp) and HSV-2 incidence (5.6 pp) in the VE arm. Two years after the end of the interventions, girls continued to have increased schooling, sexual and reproductive health knowledge, and improved financial savings behaviors. Qualitatively, respondents reported that girls were likely to have sex as a result of child sexual exploitation, peer pressure or influence from the media, as well as for sexual adventure and as a mark of maturity.
This study demonstrates that multisectoral cash plus interventions targeting the community and household level, combined with interventions in the education, health, and wealth-creation sectors that directly target individual girls in early adolescence, generate protective factors against early pregnancy during adolescence. Such interventions, therefore, potentially have beneficial impacts on the longer-term health and economic outcomes of girls residing in impoverished settings.

绝大多数青少年生育发生在低收入和中等收入国家,且对母亲及其子女均会产生负面后果。众多风险因素或许可以解释为何鲜有项目能成功推迟生育,并表明多部门干预可能是必要的。本研究考察了一项为期两年(2015 - 2017年)的多部门项目对肯尼亚一个城市非正式定居点青少年初次性行为和生育的长期影响。
该研究采用随机试验设计,对2015年11 - 14岁的2075名女孩进行纵向跟踪直至2019年。干预措施包括关于不平等性别规范及其后果的社区对话(预防暴力)、有条件现金转移(教育)、健康和生活技能培训(健康)以及金融知识培训和储蓄活动(财富)。女孩们被随机分配到四个研究组之一:1)仅预防暴力组(V组);2)V组和教育组(VE组);3)VE组和健康组(VEH组);或4)所有四项干预措施组(VEHW组)。我们使用协方差分析来估计每个研究组以及合并研究组VE、VEH和VEHW相对于V组在生育和单纯疱疹病毒2型(HSV - 2)感染的主要结局以及教育、健康知识和财富创造的次要结局上的意向性治疗(ITT)影响。对基线时13 - 14岁的大龄女孩进行了事后分析。2018年,在VEHW组,对青少年女孩、她们的父母、学校工作人员、导师、社区对话促进者和社区守门人进行了深入的定性评估。该试验已在国际标准随机对照试验编号注册系统(ISRCTN)注册:ISRCTN77455458。
在仅预防暴力的研究组的终期,21.0%的女孩报告有过性行为,7.7%的女孩曾怀孕,6.6%的女孩曾生育,大龄子样本的比例更高,分别为32.5%、11.8%和10.1%。在整个样本中,VE组和VEHW组的曾生育比例降低了2.3个百分点(pp),在10%水平上具有显著性。对于大龄子样本,VE组在曾有性行为比例(8.2 pp)、HSV - 2患病率(7.5 pp)和HSV - 2发病率(5.6 pp)方面有更大且显著的降低。干预结束两年后,女孩们的受教育程度、性与生殖健康知识以及金融储蓄行为持续改善。定性方面,受访者报告称女孩发生性行为可能是由于儿童性剥削、同伴压力或媒体影响,以及出于性冒险和作为成熟的标志。
本研究表明,针对社区和家庭层面的多部门现金加干预措施,再加上在教育、健康和财富创造部门直接针对青春期早期个体女孩的干预措施,可产生预防青少年早期怀孕的保护因素。因此,此类干预措施可能对生活在贫困环境中的女孩的长期健康和经济结局产生有益影响。
