Health Education Model Led by Community Health Volunteers.

The goal of this intervention study is to investigate the level of knowledge, attitudes, and behaviors of students on schistosomiasis in Pemba Island. It aims to test the effectiveness of establishing a widely applicable Community Health Volunteers model in the Zanzibar region and explore the feasibility of promoting this model in other areas of Africa. This study also aims to provide valuable insights and references for global schistosomiasis prevention and control efforts.

About this study

The main questions it aims to answer are:

Conducting a survey to understand the current knowledge levels, attitudes, and relevant health behaviors of Pemba Island students towards schistosomiasis.

Performing qualitative research to analyze the factors influencing students' knowledge, attitudes, and behaviors related to schistosomiasis, as well as observing the facilitators and barriers to conducting health education among student groups, in order to provide a scientific basis for targeted intervention measures.

Testing the effectiveness of establishing a widely applicable community health volunteer model in the Zanzibar region and exploring the feasibility of promoting this model in other regions of Africa, thereby providing insights and references for global schistosomiasis prevention and control efforts.

Participants will select fourth and fifth grade students from two schools located in high-risk schistosomiasis prevalence areas on Pemba Island, with Kilindi Primary School as the intervention group and Shumba Viamboni or Chambani primary school as the control group from Feb 2024 to Feb 2025. Apart from the KAP survey, urine samples will be collected from students three times at least and the prevalence confirmed to compare the effectiveness of the two groups.

Treatment and study plan

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.

Primary outcomes

  1. Change in Infection Rate

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

    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)

  2. Change in Knowledge Scores

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

    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

  3. Attitudes Changes

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

    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

  4. Behaviors Changes

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

    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
