Aim: to evaluate the effectiveness of a mobile application to improve the links between STH infection rate, nutritional status, and school performance of schoolchildren in Cagayan Valley, Philippines
Hypothesis: A mobile application will improve the status of STH infection rate, nutritional status, and school performance of schoolchildren in Cagayan Valley, Philippines Background: An assessment was done to determine the gaps and barriers in interventions for the control of soil-transmitted helminthiasis among schoolchildren in 20 schools in Cagayan Valley, Philippines. We found out that there was no structured health education program among these schools that focus on the elimination of STH infections. Despite of annual immunization with albendazole, the cumulative STH infection rate (of at least one STH species) has reached more than 20% threshold set by the WHO. We measured the knowledge, attitudes, and practices of the schoolchildren to determine the needed contents of the mobile application as an intervention.

Primary Outcomes (end points)
To avoid STH infection among schoolchildren in Cagayan Valley, Philippines
Primary Outcomes (explanation)
Schoolchildren improved self-care management. It will be operationalized using the information, motivation, and behavioral skills (IMB) model. In this model, “information” consists of basic knowledge about STH infection, symptoms of the infection, transmission of the infection, and how to avoid the infection. “Motivation” covers intrinsic motivation of personal attitude toward beliefs on the value of proper hygiene and sanitation. “Behavioral skills” include ensuring that the schoolchildren are equipped with behavioral tools necessary to perform behaviors such as proper hand washing, proper use of toilet, and habitual wearing of footwear.
Secondary Outcomes (end points)
Nutritional status of schoolchildren, school performance of schoolchildren
Secondary Outcomes (explanation)
Group B will be exposed to the mobile application or the content of the mobile application. If accessing mobile application is not possible, the content of the mobile application will be flashed on the classroom TV of the schoolchildren. The use of the mobile application will be monitored through web-based admin system. If the usage of the mobile application is declining, we will contact the teacher to follow-up the children to visit the mobile application. OR the teacher will be given a schedule to instruct the children to regularly visit the mobile application once a week.
With various theories that we reviewed and with practicality considerations, we created a coherent program leading to the development of the mobile application we called “WASHAppKids!”. WASHAppKids is an easy-to-use, noninvasive, nonpharmacological mobile application developed with four main features: (1) Kwentong Pambata (Short Stories for Children), (2) Bidyong Pambata (Storytelling Videos), (3) Bulate Knowledge Quiz (Worm Knowledge Quiz), and (4) WASH App Kids Information.
