Table 1 Outcome indicators and expected results among schoolchildren in three intervention arms (SG, SG+ and control) in a randomised controlled trial conducted in two districts of Nepal between March 2015 and June 2016

Outcome 1 (Primary outcome)

Change in knowledge about fruits and vegetables, malnutrition, anaemia and intestinal parasitic infection

Schoolchildren know about:

• the average daily requirement of intake of fruits and vegetables

• malnutrition and its causes

• importance of consuming fruits and vegetables for improved health

• WASH and related diseases including intestinal parasitic infections

Outcome 2

Change in dietary diversity and fruits and vegetables intake

• the dietary diversity score (DDS) and the average fruits and vegetables consumption will increase among school children among SG+

• the dietary behaviour translates into behaviour change towards increased fruits and vegetables consumption

Outcome 3

Change in nutritional status and haemoglobin level

• the improvement in children’s weight and height among schoolchildren in the SG+ arm

• the increase of blood haemoglobin levels among schoolchildren in the SG+ arm

Outcome 4 (Primary outcome)

Change in intestinal parasitic infection

• the incidence of intestinal parasitic infections among schoolchildren from intervention schools will be decreased

Outcome 5

Change in water quality, sanitation and hygiene conditions

• WASH conditions will be improved with well-tailored package of interventions implemented at the unit of schools and households
