Clinical Trial Summary
A 4-armed cluster randomised controlled trial conducted among secondary schoolgirls in Siaya,
western Kenya, where clusters are the unit of allocation and schoolgirls the unit of
measurement. The overall aim of the trial is to inform evidence-based policy to develop
intervention programmes which improve adolescent girls' health, school equity and
life-chances. The primary objective is to determine the impact of menstrual cups or cash
transfer alone, or in combination, compared against controls, on a composite of deleterious
outcomes (HIV, HSV-2 infection, and school dropout) over 3 schoolyears follow-up.
Description:
Title: Menstrual cups and cash transfer to reduce sexual and reproductive harm and school
dropout in adolescent schoolgirls in western Kenya: a cluster randomised controlled trial.
Short Title: Cups or cash for girls (CCg) trial
Background and rationale: Adolescence is a critical time of psychological and biological
change, and advocacy has increased to identify interventions that protect against sexual and
reproductive health (SRH) harms, which are disproportionately high among adolescent girls in
sub-Saharan Africa. In much of eastern and southern Africa including western Kenya, where
unprotected transactional sex is common, young females are highly vulnerable to sexually
transmitted infections (STIs), including HIV, and pregnancy resulting in school dropout.
While the burden of young female SRH harms is high for individuals, communities and health
services, sustainable preventive interventions are lacking. Evidence of a positive
association between girls' education, health and economic potential has strengthened
international resolve to improve educational opportunities for adolescent girls. While SRH
education has minimal impact on SRH harms, staying in school has shown to protect girls
against early marriage, teen pregnancy, and HIV infection, with schoolgirls reporting less
frequent sex, and fewer partners with less age disparity. While MDGs focused on primary
school attendance, the post-2015 Sustainability Development Goals continue to encourage
investment in secondary, tertiary and vocational education to build human capital, innovation
and economic growth, but require the support of cost-effective interventions. Interventions
using cash transfer (CT) have demonstrated a protective effect on girls SRH (HIV, HSV-2,
sexual behaviours, and school indicators). Menstrual hygiene management (MHM) is a pervasive
problem across low middle income countries (LMICs) and a lack of MHM materials and facilities
negatively impact girls' school-life. This increases girls' vulnerability to coercive sex,
which often creates a pathway to obtain necessities such as soap, sanitary products, and
underwear; 10% of 15 year old girls report that they obtain money through sex to purchase
sanitary products in western Kenya. To tackle these challenges, our team ran a pilot
menstrual study in western Kenya. It provided MHM tools to adolescent girls in the form of
reusable menstrual cups and disposable sanitary pads. The results demonstrated a lower
prevalence of STI and bacterial vaginosis among girls who were provided with a single
menstrual cup (one cup can last up to 10 years), and a lower prevalence of school dropout
after 12 months follow-up compared to controls. This pilot requires replication in a larger
trial population with longer follow-up. Comparison against CT offers an opportunity to
examine the efficacy and cost-effectiveness of these different approaches to improve girls'
life-chances in rural western Kenya. The study is designed to inform evidence-based policy to
improve girls' health, school equity and their life-chances.
Primary objective: To determine the impact of menstrual cups alone, cash transfer alone, or
the two in combination, in secondary schoolgirls on a composite of deleterious outcomes (HIV,
HSV-2 infection, or school dropout).
Hypothesis: The investigators postulate the interventions tested will break the cycle of
sexual and reproductive ill-health, under-achievement, and poverty which impede girls'
successful completion of school.
Overview Study Design: Single site open-label 4-arm, school-cluster randomised controlled
superiority trial. Schools are the unit of randomisation (clusters), with girls the unit of
measurement. Schools will be randomly allocated into 4 arms using a 1:1:1:1 ratio and
permuted block randomisation to minimise bias. Enrollment will be staggered over >=2 school
terms if logistically required. Girls will be followed-up through graduation and into
employment or up to 10 academic terms to determine if they complete secondary school (Form
4). Sealed, opaque envelopes will be prepared with the study allocation. Counsellors
conducting HIV and HSV-2 testing, and laboratory technicians will be blinded to the study
arm. Field staff who conduct home visits to confirm dropout will also be masked where
feasible.
Sites: The study will be conducted in Siaya County, western Kenya. Depending on the
recruitment rate enrolment will be expanded to other neighbouring counties.
Study Population: Secondary schoolgirls who attend eligible schools in the western Kenya
study site. Girls will be residents of the area, with a history of established menses (>=3
times), no disability preventing participation, with parent or guardian's consent and girl's
assent. Girls attending boarding schools or with visible/declared pregnancy will be excluded
at baseline.
Study Interventions: 1. One menstrual cup (Mooncup®) with handwash soap termly; 2. Cash
transfer (CT; girls' pocket money) via local community/mobile banking with financial
literacy; 3. A combination of cup and CT interventions; 4. 'Usual practice' (control) with
handwash soap termly.
Outcome Measures: Primary efficacy outcome: Composite endpoint comprised of incident HIV,
HSV-2, and all-cause school dropout, by end of follow-up. Key secondary outcomes include
incident HIV, HSV-2, school dropout, BV and reported sexual behaviours including pregnancy,
quality of life measures, school indicators (performance, grade repitition, re-enrolment,
absence, transfers), and cost-effectiveness. Primary safety outcome measure: toxic shock
syndrome (TSS), and severe violence associated with intervention. Key secondary safety
outcome include contamination on menstrual cups and other emergent harms associated with the
interventions.
Follow-up procedures: HIV and HSV-2 serostatus will be assessed at baseline and around the
time of final school term (Form 4), with interim testing or annual testing if funding allows,
including for bacterial vaginosis and other STI. School dropout will be assessed every term
until the end of Form (class) 4. Other endpoints will be evaluated at baseline, midline, and
end of study. Safety monitoring of TSS and physical violence will be conducted throughout by
study nurses, supplemented by health facilities and evaluation of HDSS census mortality data.
Sample size: Main trial: 84 schools (clusters) (21 per arm) with an approximate average of 46
girls per school (~3864 participants, 966 per arm). Protocol amendment v7: 96 schools with
approximately 41.5 girls per school (3980 participants, 995 per arm).
Data Analysis: Primary trial analyses will be based on the intention to treat principle and a
secondary analyses will also be done on the per protocol population. Generalised estimating
equation (GEE) log binomial models will be used to analyse the primary endpoint and its
components. The GEE model will include the arm as a fixed effect and school as a cluster
effect. The RR values for the 5 pre-specified primary comparisons together with their 95%
confidence intervals will be derived from the GEE model. The secondary endpoints will be
analysed similarly using GEE models. For GEE analysis of a continuous endpoint such as
quality of life, normal distribution and identity link functions will be used. For GEE
analysis of a binary outcome (such as having an event of STI, HIV, pregnancy, or school
dropout), binomial distribution and log link functions will be used; for GEE analysis of
recurrence of events (such as number of sexual partners during a specific time), Poisson
distribution and log link functions will be used. Covariate adjusted analysis of primary
endpoint will be performed within the GEE framework with treatment as the study variable, and
other predictors as covariates, and school as cluster effect. For qualitative analysis, FGD
recordings will be transcribed verbatim with back translation. Transcripts will analysed
using thematic analysis by study group, 2 researchers will separately assign codes for
emergent themes, subthemes patterns, and associations using NVIVO with intercoder reliability
checked and consensus reached following discussion. As themes emerge, differences and
similarities will be compared across trial arms, and between study groups. Qualitative data
from in depth interviews will be similarly evaluated. Protocol amendment v10:Secondary
analysis on primary and secondary outcomes using 'at the margins' factorial analysis will
also be conducted.
