Background and study aims
This is a follow-up study of the MAGNUS nutrition intervention trial (ISRCTN13093195) that was conducted in 2020. The MAGNUS trial was conducted to assess the role of milk protein and whey permeate in a large quantity lipid-based nutrient supplement (LNS) on the growth and development of 1–5-year-old children who were already stunted. Findings from this study showed that supplementation with LNS, irrespective of additional milk ingredients, supports linear catch-up growth and accretion of fat-free mass (FFM), but not fat mass (FM), in children with stunting. In contrast, among children who were not supplemented, stunting worsened and they gained fat at the expense of fat-free mass.
The MAGNUS 2 study aims to assess the long-term effects of LNS supplementation on the growth and development of children from the MAGNUS trial, who are now 6–10 years old. The study will also explore the association between stunting and early signs of cardiometabolic risk markers, and whether these are affected by supplementation with LNS. A new reference group of non-stunted children will be established for this purpose.
Who can participate?
Children with early stunted growth who participated in the former MAGNUS study can participate. In addition, we will recruit age- and sex-matched reference children without stunting from the same communities.
What does the study involve?
Children will be screened and referred to a clinic site for a full-day evaluation. After eligibility testing and informed consent/assent is obtained, the following data are collected: questionnaires on medical history, demographics and dietary information; clinical assessment including ultrasound scans (liver, spleen, kidneys, abdominal fat) and blood pressure assessment; anthropometrics of the mother (weight, height) and the child (weight, height, mid-upper arm and waist circumferences, subscapular and triceps skinfolds). Child bioelectrical impedance is measured to assess body composition, and child development is assessed by the Kaufman Assessment Battery for Children II test. School grades are collected, and grip strength and broad jump are measured. Finally, blood and stool samples are collected. After the examination at the study site, children are escorted home and WASH assessment and home-based questionnaires are conducted. Stool sample collection and home assessments may be done on another day.
What are the possible benefits and risks of participating?
Clinical benefits: Children will benefit from nutritional assessments, medical examinations, and blood haemoglobin and sugar tests. Families will also receive nutrition counselling and children will be referred if needed.
Community benefits: Training village health teams and clinical staff will build local capacity and raise awareness about child malnutrition, encouraging future screening at community clinics.
Procedural risks: Risks are minimal. Blood samples may cause brief discomfort but are taken by trained nurses. Ultrasound and bioelectrical impedance procedures are very safe and painless.
Where is the study run from?
The study is a community-based study. Participants will be recruited from villages around two health centres in Eastern Uganda: Walukuba Health Centre IV and Buwenge Health Centre IV.
When is the study starting and how long is it expected to run for?
September 2024 to April 2026

| Scientific title | Reducing short and long-term consequences of early stunted growth. MAGNUS 2 – Milk affecting growth, cognition and the gut in child stunting |
| Study acronym | MAGNUS 2 |
| Study objectives | Main objective: To assess long-term effects of supplementation with large quantity LNS on child health Primary objectives: 1. To assess the long term effects of 3-months supplementation with large-quantity LNS among 1-5-year old Ugandan stunted children on cardiometabolic risk markers at age 6-10 years. 2. To assess the association between stunting and cardiometabolic risk among 6-10-year-old Ugandan children. Secondary objectives: 1. To assess the long-term effects of 3-months supplementation with large-quantity LNS among 1-5-year-old Ugandan stunted children on growth, body composition, child development, haemoglobin, micronutrient status and organ size (liver, kidney, spleen) at age 6-10 years. 2. To assess the long-term effects of 3-months supplementation with large-quantity LNS among 1-5-year-old Ugandan stunted children on gut microbiota and function at age 6-10 years. 3. To assess predictors of cardiometabolic risk markers among 6-10-year-old previously stunted Ugandan children. 4. To assess the associations between stunting and growth, body composition, child development, haemoglobin, micronutrient status and organ size (liver, kidney, spleen) among 6-10-year-old previously stunted Ugandan children. 5. To assess the associations between stunting and gut microbiota and function among 6-10-year-old previously stunted Ugandan children. |

| Health condition(s) or problem(s) studied | Childhood stunting |
| Intervention | Children with early stunting who participated in the MAGNUS 1 trial will be invited for a 1-day follow-up at the same health facility as they attended in MAGNUS 1. We expect to be able to relocate up to 650 out of 750 children from MAGNUS 1. In addition, we will recruit 200 new reference children without stunting who will undergo the same questions, tests and examinations. After inclusion, the following data are collected: questionnaires of medical history, demographics and dietary information, clinical assessment is conducted, including ultrasound scans (liver, spleen, kidneys, abdominal fat) and blood pressure assessment, anthropometrics of the mother (if available) and child are measured. Child bioelectrical impedance is measured to assess body composition and child development is assessed by the Kaufman Assessment Battery for Children II test, school achievement, grip strength and broad jump. Finally, blood and stool samples are collected. After the examination at the study site, children are escorted home and WASH assessment and home-based questionnaires are conducted. Stool sample collection and home assessments may also be done on another day. |
