Impact of Malaria Prevention on Health and Education in Kenyan Schoolchildren
Studienübersicht
Status
Detaillierte Beschreibung
This study will be a factorial-design, cluster-randomised trial with a comparison group to assess the impact of (i) malaria prevention, based on screening and treatment, and (ii) enhanced literacy instruction by teachers on the health and educational achievement of healthy schoolchildren.
The target population in this study includes children attending primary schools in Kenya. The accessible population includes the children attending the participating primary schools in classes 1 and 5 in Kwale district. Schools will be randomized to one of four groups, receiving either the screening and treatment intervention alone, the education intervention alone, the malaria and education interventions combined, or neither intervention. The unit of analysis is the school, but individual-level analysis using suitable generalised linear models, adjusted for clustering by school, will also be undertaken to explore differences in impact of the interventions according to child age, sex, home environment, school quality as well as differences in the uptake of each intervention.

Experimental: 1
Intermittent screening and treatment (IST) for malaria. This intervention is a change from a previous intervention based on intermittent preventive treatment for malaria owning to the withdrawal of amodiaquine (one of the previous IPT drugs) in Kenya in 2009. |
All children will be screened for malaria using rapid diagnostic tests (RDTs) once a term (thrice yearly).
Children (with or without clinical malaria symptoms) found to be RDT-positive will be treated with artemether-lumefantrine according to national guidelines.
Screening and treatment will be administered by district public health staff once a school term, observed by the evaluation research team.
|
|
Experimental: 2
Enhanced teacher training on literacy instruction.
|
Education intervention designed to improved early grade literacy instruction, focusing on phonological awareness & vocabulary and relationship between letters and sounds in a systematic and explicit fashion.
Specific interventions will include training on (i) how to monitor students' progress in large classes (ii) developing and using instructional materials for reading (iii) lesson planning for explicit teaching of letter-sound relationships (iv) instructional techniques for large classes.

|
Experimental: 3
Intermittent screening and treatment (IST) for malaria and enhanced teacher training on literacy instruction
|
Schools will receive both IST and the literacy instruction programme
