Abstract
Background
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 longerterm
impact of a two-year (2015–17) multisectoral program on early sexual debut and fertility
in an urban informal settlement in Kenya.
Methods
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.
Results
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.
Conclusion
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.
