Study summary

This study aims to assess the effects of school-based, comprehensive water, sanitation, and hygiene improvements on child health and educational outcomes in schools in Addis Ababa, Ethiopia. Eligible schools will be randomly allocated to intervention or control groups. Data on pupil absence and illness will be collected longitudinally from students in selected classrooms in each school over the course of one academic year (2021/2022). This study will also assess the effects of the intervention on kindergarten students through parent interviews.

Read the detailed description

This study uses a cluster-randomised controlled trial design to evaluate the impact of the WASH in Schools for Everyone (WISE) programme. Project WISE, implemented by Splash, aims to improve child health and attendance by 1) improving WASH infrastructure, 2) promoting WASH behaviour change and 3) strengthening menstrual hygiene management (MHM) services targeting girls aged 10 and above, in public schools across Addis Ababa.

60 public schools from planned implementation groups that will receive the WISE intervention will be randomised: 30 schools will be allocated to the intervention group (to receive the WISE intervention during the 2021/2022 academic year) and 30 schools will be allocated to the control group (on a waitlist to receive the WISE intervention after study completion). Randomisation will be stratified by school size (number of students) and presence of a kindergarten. In each selected school, between two and four classes will be randomly selected from grades 2-8 - to obtain a sample size of approximately 100 students in total per school. Students in the selected classes will be enrolled at the start of the academic year (September 2021) and followed up with unannounced visits every 4-6 weeks until the end of the academic year (May 2022). Primary outcomes of pupil-reported illness and absence will be assessed during enrolment and at each follow-up visit. Secondary outcomes are restricted to subsets of students by age and gender, and will be assessed during the final follow-up visit. Students joining the class mid-way through the year will be enrolled in the study, and students who leave the class will be recorded.

Key outcomes of interest are longitudinal prevalence of absence and illness (diarrhoea and respiratory infection) over the course of the academic year, measured as cumulative number of days absent/with illness per 100 school days after adjustment for child- and school-specific covariates. Data collected in intervention schools prior to and/or during the active Splash intervention will not be included in the primary impact evaluation analysis. Sub-population analysis of evaluation outcomes in girls post-menarche will allow assessment of the gendered effects of the intervention. We will also monitor intervention fidelity and compliance, as well as cost-effectiveness of the intervention, through routine data collection with students and school staff.

40 public schools with a kindergarten will be enrolled to assess the impacts of the intervention among kindergarten students (20 intervention, 20 control). Schools enrolled in the intervention and control arms of the main study among older children that have a kindergarten will be also enrolled in the kindergarten evaluation. If there are fewer than 20 such schools in each arm, additional kindergarten schools will be randomised (estimated 10 additional schools per arm). In each selected school, 20 kindergarten students will be randomly selected for participation. Parents of selected students will be invited to participate in weekly telephone surveys over a four-week period in February/March 2022 in order to assess the longitudinal prevalence of illness and absence among kindergarteners.

What researchers measure

Primary outcomes

    Attendance on the day of data collection will be recorded for all children in selected classes. This indicator is collected longitudinally over the course of the study at follow-up visits every 4-6 weeks.

    Time frame: Longitudinal: Every 4-6 weeks. Participants will be followed for 9 months (September 2021-May 2022)

  2. Self-reported absence prevalence - Older children (7-16)

    All children present in selected classes will be asked to report full- and partial-day absence over the past week of school. This indicator is collected longitudinally over the course of the study at follow-up visits every 4-6 weeks.

    Time frame: Longitudinal: Baseline and every 4-6 weeks. Participants will be followed for 9 months (September 2021-May 2022)

  3. 2- and 7-day period prevalence of diarrhoea - Older children (7-16)

    All children present in selected classes will be asked whether they have had diarrhoea within the past 2 and 7 days. This indicator is collected longitudinally over the course of the study at follow-up visits every 4-6 weeks.

    Time frame: Longitudinal: Baseline and every 4-6 weeks. Participants will be followed for 9 months (September 2021-May 2022)

  4. 2- and 7-day period prevalence of respiratory infection - Older children (7-16)

    All children present in selected classes will be asked whether they have had specific symptoms of respiratory infection within the past 2 and 7 days. This indicator is collected longitudinally over the course of the study at follow-up visits every 4-6 weeks.

    Time frame: Longitudinal: Baseline and every 4-6 weeks. Participants will be followed for 9 months (September 2021-May 2022)

  5. Days with diarrhoea in past week - Kindergarten (4-6)

    Parent-reported days with diarrhoea among kindergarten students with one-week recall period, assessed using telephone surveys. Cumulative days with diarrhoea over the four-week period will be calculated.

    Time frame: Longitudinal: Weekly for four weeks (February/March 2022).

  6. Days with respiratory infection in past week - Kindergarten (4-6)

    Parent-reported days with symptoms of respiratory infection among kindergarten students with one-week recall period, assessed using telephone surveys. Cumulative days with respiratory infection over the four-week period will be calculated.

    Time frame: Longitudinal: Weekly for four weeks (February/March 2022).

  7. Absence in past week - Kindergarten (4-6)

    Parent-reported days of absence from kindergarten with one-week recall period, assessed using telephone surveys. Cumulative absence over the four-week period will be calculated.

    Time frame: Longitudinal: Weekly for four weeks (February/March 2022).

Secondary outcomes

  1. Strengths and Difficulties Questionnaire (SDQ) total score - Older children (11-16)

    Children aged 11 or older in selected classrooms will complete the self-rated SDQ (25 items) as a measure of wellbeing.

Ran from Nov 2021 to primary completion in Jul 2022, 7 months.

Of 125 non-industry interventional studies with no phase under Diarrhea, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 38. This study's 7 months is below that.

Counting every sponsor, half of 156 studies reached it within 19 months; a quarter within 6 and three quarters within 36.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 19, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
