An interventional study of Multicomponent school nutrition intervention and Usual nutrition program in Overweight Adolescents, Underweight and Obese Adolescents, sponsored by Norwegian University of Science and Technology. Not yet recruiting at 2 sites in 2 countries. Open to participants aged 11 Years to 15 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-01-12.

The goal of this clinical trial is to learn if a multicomponent nutrition program developed together with the students, parents, teachers and canteen operators will improve nutrition status of adolescents. It will also learn about the acceptability and feasibility of implementing the program in the school settings. The main questions it aims to answer are:
What is the effect of co-created multicomponent intervention promoting healthy food behavior and environment in schools on the proportion of normal weight adolescents? What proportion of the target adolescents and teachers does the intervention reach? What proportion of the schools are willing to implement the intervention? What was the level of fidelity of implementation of all components of the intervention and the barriers and facilitators to implementation? What is the cost for maintenance, and facilitators and barriers of sustainment? School going adolescents studying in grades 7 to 9 from 26 schools in India and 26 schools in Nepal will be enrolled in the trial and their height, weight, dietary behavior, mental well-being and physical activity will be measured at baseline and at 12 months follow up. After the baseline assessment the school community (students, school environment, parents, teachers, canteen operators) will receive the intervention.
66 studies on the registry are indexed under Thinness; 11 are open to participants now.
This study's planned enrollment of 2,600 is above the median of 287 across 43 interventional studies indexed under Thinness.

The intervention will include innovative components that aims to change school food environment, nutrition education to promote healthy eating and community and parental involvement. This section will be completed after the intervention package is finalized during the co-creation phase.
Usual nutrition program that is being implemented, no any additional active intervention
Proportion of healthy weight adolescents and body mass index for age
Height and weight of the adolescents will be measured to calculate body mass index using age and sex specific charts and categorize them as Underweight: Less than the 5th percentile, Healthy weight: 5th percentile up to the 85th percentile , Overweight: 85th percentile to less than the 95th percentile, Obesity: 95th percentile or higher
Time frame: At enrollment and at 12 months follow up
Total intake of fruits and vegetables, dairy products, meat and beans (protein), whole grains, sugar-sweetened beverages, fast food, and salty snacks
A 24 hour dietary recall will be taken (two times during week days and weekends)
Time frame: At enrollment and at 12 months follow up
Total metabolic equivalent per day (MET per day)
Use International Physical activity questionnaire for adolescent to measure specific types, frequency and duration across different domains.
Time frame: At enrollment and at 12 months follow up
Mental wellbeing
Measured using Warwick-Edinburgh Mental Well-Being Scale (WEMWBS)
Time frame: At enrollment and at 12 months follow up

Start is estimated for Oct 2026; primary completion for Dec 2027, 14 months later.
Of 22 interventional studies with no phase under Thinness, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 30. This study's planned 14 months is below that.
