Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will be a video-based health education package comprised of: 1) health education cartoon: narrative 12 min cartoon video; content: story about a boy who gets infected with Soil-transmitted Helminths (STH) because of unhygienic behaviour. Key messages: a) symptoms of the disease. b) where and how can children get infected. c) how can disease be prevented. 2) A take-home pamphlet with key messages; 3) Classroom discussions; and 4) Drawing and essay competitions for key message reinforcement.

The cartoon will be shown twice (immediately following each other) in June/July 2016 followed by distribution of the pamphlet and classroom discussions (for 10-15 mins post the viewing by the research team assisted by the child's regular teacher); and then shown twice (immediately following each other) in August/September 2016 followed by classroom discussions (for 10-15 mins post the viewing by the research team assisted by the child's regular teacher) and the drawing and essay competitions. This will take place in the intervention schools.

Albendazole chemotherapy will be administered following the baseline survey in July 2016 in all study schools. Albendazole will also be administered to those found positive at the two follow-up surveys in Feb 2017 and Feb 2018 respectively. The Albendazole regimen will follow standard World Health Organization (WHO) guidelines (a single oral dose of 400mg). This will done in concert with the National de-worming program in the Philippines

Intervetnion and drug delivery will be directly observed and record kept for monitoring purposes

Outcomes
Primary outcome [1] 295429 0
Soil-transmitted helminth infection rate will be assessed by follow-up
parasitological stool tests using Kato-Katz thick smear to count the
parasite eggs per species. Molecular diagnostics will also be undertaken.
Timepoint [1] 295429 0
Soil-transmitted helminth infection rates will be assessed at baseline (June/July 2016) and then at each follow-up (Feb/March 2017 and Feb/March 2018).
Primary outcome [2] 295430 0
Child's knowledge on infection risk of soil-transmitted helminth will be assessed with baseline and follow-up questionnaires. These questionnaires were designed specifically for the study, although they were an adaptation (to the Filippino context) of what we have used in previous trials in China
Timepoint [2] 295430 0
Knowledge will be assessed at baseline (July/August 2015) and at follow-up (Feb/March 2016 and Feb/March 2017).
Secondary outcome [1] 315571 0
Measures of STH associated morbidity (anaemia). This will be measured by Haemoglobin levels (blood via finger prick and Hb machine) at baseline and follow-up.
Timepoint [1] 315571 0
Morbidity measures will be assessed at baseline (June/July 2016) and at follow-up (Feb/March 2017 and Feb/March 2018).
Secondary outcome [2] 323014 0
Measures of STH associated morbidity (stunted growth). This will be measured by height and weight (stadiometer and calibrated digital scales) at baseline and follow-up.
Timepoint [2] 323014 0
Assessed at baseline (June/July 2016) and at follow-up (Feb/March 2017 and Feb/March 2018).
Secondary outcome [3] 323015 0
Measures of STH associated morbidity (academic performance). This will be measured by school attendance and academic grades (obtained from school records); at baseline and follow-up.
Timepoint [3] 323015 0
Assessed at baseline (June/July 2016) and at follow-up (Feb/March 2017 and Feb/March 2018).

All 4th grade students in the selected study schools, from whom's
informed consent was received, will be enrolled for the study. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple Randomisation: Random number generation will be used in MS Excel to randomise schools into control or intervention groups

Efficacy
Statistical methods / analysis
We estimated a design effect of 1.1 based on our previous study. Sample size calculations were then undertaken for an individually randomized trial and multiplied by the design effect. Assuming an STH incidence of 18% (typical of communities with 50% prevalence) and an intervention efficacy of 33%; the study will have 80% power with a
sample size of 20 intervention clusters (40 in total) and 44 students per cluster at the end of the trial following a predicted annual 10% loss to follow-up (total N = 1760).

Statistical analyses
A hierarchical generalised linear model with school as a random effect will be used for formal analyses of infection and knowledge, and carried out using SAS software (SAS Institute, Cary, NC). Models will be fitted using Generalised Estimating Equations (GEE) and a log-binomial distribution used to estimate relative risks and therefore intervention efficacy against infection. Analyses of changes in knowledge and
behaviour scores will use a log-normal distribution, and a timeintervention interaction to estimate differential change over time. Potential confounders such as age and sex will be incorporated. Spearman correlation coefficients will be used to estimate correlations among behaviour, knowledge, and incidence.
