Outcome Measures

Primary Outcomes (4)

• Change in Infection Rate

  For biological sample collection, students provided first-morning urine samples (30-50 mL) in sterile, pre-labeled wide-mouth containers under teacher supervision to ensure protocol adherence. Certified laboratory technicians performed standardized filtration and microscopic analysis to detect S. haematobium eggs. All egg counts were initially recorded manually, then entered into a Microsoft Excel database using dual-entry verification to maintain data integrity. Infection intensity classified by WHO criteria (light: 1-49 eggs/10ml urine; heavy: ≥ 50 eggs/10ml urine)

  before the intervention, six months after the intervention, and at the end of the one-year observation period

• Change in Knowledge Scores

  Measurement Tool: "Schistosomiasis Knowledge Questionnaire" Description: This questionnaire assesses the knowledge level of students regarding schistosomiasis. Scale Title: Schistosomiasis Knowledge Questionnaire Range: Minimum value: 0, Maximum value: 10 Interpretation: Higher scores indicate a better understanding of schistosomiasis

  before the intervention, six months after the intervention, and at the end of the one-year observation period

• Attitudes Changes

  Measurement Tool: "Schistosomiasis Attitudes Questionnaire" Description: This questionnaire assesses the attitudes level of students regarding schistosomiasis. Scale Title: Schistosomiasis Attitudes Questionnaire Range: Minimum value: 11, Maximum value: 55 Interpretation: Higher scores indicate more positive attitudes related to schistosomiasis

  before the intervention, six months after the intervention, and at the end of the one-year observation period

• Behaviors Changes

  Measurement Tool: "Schistosomiasis Behaviors Questionnaire" Description: This questionnaire assesses the behaviors level of students regarding schistosomiasis. Scale Title: Schistosomiasis Behaviors Questionnaire Range: Minimum value:10 , Maximum value:30 Interpretation: Higher scores indicate more positive behaviors related to schistosomiasis

  before the intervention, six months after the intervention, and at the end of the one-year observation period

Study Arms (3)

CHVs Intervention group

EXPERIMENTAL

A group of students who receive schistosomiasis health education intervention led by community health volunteers.

Behavioral: health education

Control A

NO INTERVENTION

A group of students who do not receive schistosomiasis health education intervention led by community health volunteers. The control arm received conventional education.

Control B

NO INTERVENTION

A group of students who do not receive schistosomiasis health education intervention led by community health volunteers. The control arm received conventional education.

Interventions

health education BEHAVIORAL

In the intervention group, we provide schistosomiasis health education to students once a month through community health volunteers for a duration of six months. After that, the community health volunteers no longer visit the school for health education until the completion of a one-year follow-up period.
