Study Description
Brief Summary:

The main objective of the project was to determine the effect of integrated school based deworming and health education on prevalence and morbidity due to co-infection infection with schistosomiasis, STHs and malaria among primary school age children living in rural and farming areas in Zimbabwe

There is need for regular school based de-worming and health education programs for the helminths-Plasmodium co-infections in primary schoolchildren living in rural and commercial farming areas in Zimbabwe

Condition or disease Intervention/treatment
Integrated Control of Malaria and Polyparasitism Behavioral: Health education intervention

Groups and Cohorts

Group/Cohort Intervention/treatment
health education
This was an intervention follow up Knowledge Attitude and Practice study that investigated the distribution of polyparasitism with schistosomiasis, STHs and P. falciparum among primary schoolchildren.
Behavioral: Health education intervention
Health education was conducted in two ways. (1) Teachers were taught how to use the flip chart that contained health education material about parasites. The lessons were done during free periods as this intervention had not been formally fitted into the school syllabus. (2) The research team provided health education to school children. Focus group discussions were conducted by the research team with school children all assembled outside their classes. Health education leaflets were distributed to all school children at the school. Children were asked to share the health information with their friends and families.
Other Name: Knowledge Attitude and Practice intervention

Outcome Measures

Primary Outcome Measures :
  1. This study was conducted to determine the prevalence of polyparasitism among primary school children living in rural and commercial farming areas in Zimbabwe. [ Time Frame: 3 years ]
    This study was conducted to determine the prevalence of polyparasitism, the impact of polyparasitism on anaemia, the effect of combined school based treatment for STHs, schistosomiasis, health education and prompt malaria treatment on anaemia and prevalence of polyparasitism in primary school children.

Secondary Outcome Measures :
  1. Impact of school based parasite treatment and health education intervention. [ Time Frame: 3 years ]
    To determine the impact of combined school based deworming and prompt malaria treatment on prevalence of helminths-Plasmodium co-infections, anaemia and severity of anaemia among primary schoolchildren in rural and commercial farming areas in Zimbabwe. Combined school based parasite treatment were performed at baseline and at each follow up survey. Sustained prompt malaria treatment was performed throughout the study period.
