Brief Summary

In Zambia, the health and well-being of children aged 5 to 14 has often been overlooked, leading to various health challenges affecting their development and education. The Healthy Learners (HL) program, in collaboration with the Zambian Government, aims to address this gap by implementing a comprehensive school health program. Trained teachers, known as school health workers (SHWs), play a key role by delivering health education, coordinating preventative care with local clinics, and overseeing a 'school health room' for sick students. This study is a large cluster-randomized control trial in 225 schools. The goal of this trial is to compare the effects of the comprehensive school health programme (SHP) developed by HL against two alternatives: the current level of school health provision and the current school health activities enhanced with deworming and vitamin A coordination by HL, with their technical and financial support ensuring the reliable delivery of all health activities currently planned by the government.

1. 1.What is the impact of the program on health-seeking, health, and education outcomes?
2. 2.What are the indirect effects of the program on teachers and clinics?
3. 3.What is the added value of such a comprehensive SHP, compared to (i) optimized (ii) or imperfect (status-quo) delivery of a limited range of school health activities (e.g., deworming and vitamin A supplements)?
4. 4.How costly is the comprehensive SHP, and what factors affect its implementation?
5. 5.What are the potential benefits of the program for long-term human capital accumulation (learning, well-being etc)?

Outcome Measures

Primary Outcomes (2)

• Synthetic morbidity index

  Because the SHP delivers treatment of several diseases, we will create a composite disease burden index of the following outcomes: * malaria positive (using a rapid diagnostic test) * moderate to high worm load (using a stool test) * anaemia (using a hemocue test) * schistosomiasis (using a urine test) * diarrhoea in the past week (learner self-report) We test these outcomes in a randomly selected panel of 13,300 learners recruited at baseline, which ensures variety of age groups and balance of genders.

  18 months after intervention start

• Average attendance rate over 24 months

  We will measure attendance during unannounced attendance spot checks (one per term over a 2-year period). Multiple measurements are required to capture seasonal variation. On each spot check visit, we will check attendance of a panel of learners randomly selected at baseline, which ensures variety of age groups and balance of genders. We will calculate each child's attendance rate across all the spot checks.

Study Arms (3)

School health programme (SHP)

EXPERIMENTAL

SHP developed by Healthy Learners (HL) in collaboration with the Ministry of Education (MOE), which follows the WHO guidelines on school health activities. HL supports the upgrading of basic sanitation facilities and construction of a dedicated 'health room' in the school; trains selected teachers to become school health workers (SHWs) who deliver health and sanitation education, coordinate deworming and vitamin A supplementation in the school, and assess sick learners in the school health room using a clinical decision support system (CDSS), either treating in school or referring to the local health centre. At the health centre, children referred by SHWs are given priority by health care workers who see them within 30 minutes of arriving at the facility. Schools also create student networks (a "buddy" system) whereby learners monitor each other's absence and coordinate with SHWs, who can then follow up with the household.

Other: Comprehensive School Health Programme; Other: Deworming and vitamin A supplementation delivery

Deworming and vitamin A supplementation

ACTIVE COMPARATOR

Healthy Learners will enusre reliable delivery of the national deworming programme twice a year, during the same period as in the SHP arm, for comparability of the effect of prevention alone to the full SHP.

Other: Deworming and vitamin A supplementation delivery

Status quo

NO INTERVENTION

Schools to operate as usual with no intervention other than the usual activities planned and organized by the government, as set out the 2006 School Health and Nutrition Policy, until the end of the trial.

Interventions

Comprehensive School Health Programme OTHER

Combination intervention which consists of: * Upgrading sanitation facilities and constructing a 'health room' in the school * Health teacher training: 5-10 teachers per school are recruited and trained for two weeks to become School Health Workers (SHWs) by Healthy Learners * The SHWs: (1) deliver education on health and good sanitation and hygiene (2) coordinate with local clinics to deliver preventive care (e.g. school deworming and vitamin A supplementation); (3) assess sick students in the health room with a tablet-based clinical decision support system (CDSS); (4) treat sick students in the health room for some conditions (malaria, diarrhoea, schistosomiasis, pneumonia, conjunctivitis) or (5) refer to the health facility for treatment; (6) monitor absence of learners * Referral: learners referred by SHWs are given a referral form by the SHW, which contains information about symptoms and suggested diagnosis by the CDSS. The learners are prioritised in the local clinic.

School health programme (SHP)

Deworming and vitamin A supplementation delivery OTHER

Schools implement the government policy of distributing deworming drugs and vitamin A supplementation to learners twice a year. Additional support from Healthy Learners ensures reliable delivery.

Eligibility Criteria

• Age: 5 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

* Schools: eligible for SHP (not inaccessible in the rainy season, within 10km of health centre) * School administrator: has at least one year experience in school and is the primary or deputy school manager (e.g., headteacher, deputy headteacher, senior teacher acting as financial officer) * Learners: registered and in attendance in school during baseline, in grade 1, grade 3, or grade 5 * Parents, primary caregivers or guardians of selected learners. Guardians are eligible if they stay with the child and make schooling and health decisions for the child in the absence of parents/primary caregivers. * Teachers: any teacher employed by study eligible schools (not volunteers) * Health facilities: designated facilities in the catchment area of study schools * Health facility staff: any staff doing OPD consultation present during facility data collection days

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: NONE
• Masking Details: Blinding of intervention units, i.e. schools, to their own treatment (or that of others) is not feasible. After the initial scoping and baseline data collection (during which treatment was masked to all participants and assessors), due to the nature of the intervention, there will be no blinding: both the beneficiaries and assessors monitoring the outcomes will be able to infer whether the school is receiving the HL programme or not.
• Purpose: HEALTH SERVICES RESEARCH
• Intervention Model: PARALLEL
• Sponsor Type: OTHER
• Responsible Party: SPONSOR

Model Details: Clusters (schools) are randomised to one of 3 treatment arms. Non-compliance with treatment or control is possible if participants move between schools. We expect low rates of transfers and will track any transfers which do occur.
