Impact of Malaria Prevention on Health and Education in Kenyan Schoolchildren

14 de febrero de 2014 actualizado por: London School of Hygiene and Tropical Medicine
While malaria represents one of the main health problems afflicting schoolchildren, the evidence base for policy development and programme implementation for school-based malaria control remains inadequate. A recent study in western Kenya showed that delivering intermittent preventive treatment (IPT) to schoolchildren improved rates of anaemia and classroom concentration, but did not improve school performance. This study aims to (i) investigate the impact of malaria prevention using a strategy of periodic screening using malaria rapid diagnostic tests and treatment positives using artemether-lumefantrine (AL) on health and education among schoolchildren and (ii) determine the interaction between health and improved literacy instruction. The study hypothesis is that that school-based malaria prevention will reduce rates of anaemia or improve educational outcomes in Kenyan schoolchildren, when compared to comparison schools. In addition, a programme of training for primary school teachers to improve literacy instruction will improve literacy rates and there will be no interaction between the malaria intervention and the education intervention, such that learning will not be improved when teaching is effective and children are healthy. The study will be undertaken in 101 randomly selected primary schools in Kwale District. The malaria intervention consists of screening all children using rapid diagnostic tests (RDTs) for malaria. Children (with or without clinical malaria symptoms) found to be RDT-positive will be treated with AL 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. This intervention has been changed from IPT due to the withdrawal of amodiaquine in Kenya. The education intervention includes a programme of training for primary school teachers to improve literacy instruction. The study is designed to detect a 25% reduction in anaemia and an improvement of 0.2 standard deviations in mathematics and literacy tests. Additional outcomes will also be measured including malaria parasitaemia, classroom attention and school attendance. Cost-effectiveness and community acceptability of the interventions will be assessed. Anaemia and educational outcomes will be assessed before interventions and 12 and 24 months later. Malaria parasitaemia using blood slides will only be assessed at follow-up.

Descripción general del estudio

Descripción detallada

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
