Declarations

:

: The trial was approved by the ethics committees of the Tanzania National Institute for Medical Research (Ref: NIMR/HQ/R.8a/Vol. IX/2497) and the London School of Hygiene and Tropical Medicine (Ref: LSHTM 11868). Ethics committees approved the opt-out strategy for parent/guardian consent and provided a waiver of consent and assent for students’ participation in the intervention because hygiene-related health education and deworming campaigns should be routinely conducted at primary schools in Tanzania. For the effectiveness evaluation, all participating students were invited to provide informed written assent prior to enrolment in the surveys. Students who were not yet able to read and write could give verbal assent which was confirmed in writing by a witnessing teacher. Parents or guardians were invited to provide informed consent based on a circulated information leaflet, using an opt-out strategy for those who did not wish their children to participate. Students were given autonomy to withdraw from the evaluation surveys at any point if they wished.
