Plain English Summary

Background and study aims
A lack of physical activity, skipping breakfast, and eating unhealthy and frequent snacks are three factors that play a leading role in childhood obesity. A 2007 study carried out in Buenos Aires found that more than 25% of children aged 10-11 from middle and working class families were overweight. Most of these children reported poor eating habits including skipping breakfast, and not eating enough fruit and vegetables. Early childhood is a crucial stage for promoting healthy behaviors particularly because it is during this period that habits regarding physical activity and healthy eating are established and continue into adulthood. We also know that parents' participation, both as role models and carers, is most important to the establishment and maintenance of such habits. This is a study of a school-based program, involving parents, which aims to promote healthier habits related to breakfast, snacking, and physical activity. The aim of the study is to find out whether this program can help to reduce obesity in children.

Who can participate?
Healthy first-grade children and their parents who attend one of the 12 participating schools

What does the study involve?
The 12 participating schools are randomly allocated into four groups. Parents of the first group regularly receive online tips followed by a Q & A regarding healthy eating and active play. For children in the second group, a physical activity instructor is on hand to encourage them to get enough physical activity on the school playground. Parents and children of the third group receive both interventions. Children of the fourth group receive two classroom-based lessons, teaching them about the importance of healthy eating and getting enough exercise. Before and after the study, children and parents are measured so that weight gain can be recorded, and their eating habits and physical activity levels are measured before and after the study.

What are the possible benefits and risks of participating?
A benefit of taking part in the study is that both children and their families may have a healthier lifestyle, which improves their general health. There are no risks of participating in this study.

Where is the study run from?
International Life Sciences Institute (ILSI) (Argentina)

Scientific titleMINI SALTEN: study assessing the efficacy of a virtual intervention targeted to parents and aimed at preventing obesity in 6 year old children of public schools of Buenos Aires
Study acronymMINI SALTEN
Study hypothesisFirst grade children of public schools of Argentina are more likely to develop healthy habits related to preventing obesity if their parents are regularly exposed to a culturally appropriate educational stimuli that is delivered virtually, and monitored during 12 consecutive months.
Ethics approval(s)Institutional Review Board of the Argentine Medical Association (Comité de Ética de la Asociación Médica Argentina), 25/02/2015
ConditionObesity
InterventionThe multi-component virtual and behavioral intervention aims to promote breakfast quality and uptake, healthier snacking, and increased physical activity, with the ultimate goal of preventing childhood obesity.

The 12 participating schools are randomly assigned to two groups. The nine schools in the first group (intervention group) are separated to receive one of three intervention modalities, which was randomly assigned to three schools each. Children of the three schools of the second group are the control group.

1. Virtual: Parents are instructed and followed regarding implementation of the core objectives of the program via a software platform (www.nearpod.com), delivered bi-weekly.
2. Behavioral: Physical activity (PA) of the children is promoted by a PA instructor, who is regularly present on the school playground promoting active movement during breaks.
3. Mixed: virtual + behavioral.
4. Control arm: children receive an educational intervention in the form of two classroom workshops (nutrition and PA respectively).
Intervention typeMixed
Primary outcome measure1. Weight measured to the nearest 0.1 kg using a portable digital scale (SECA AURA 807)
2. Height measured to the nearest 0.1 cm with a portable stadiometer (Seca Stadiometer 206, Seca Corporation, Hamburg, Germany)
3. Waist circumference measured to the nearest 0.1 cm with an anthropometric tape (Sanny, Berasil)
4. BMI Z-score calculated using the 2007 WHO reference growth charts
5. Child’s and parent’s dietary intake and habits are assessed with two 24h recalls using the Multiple Pass Method completed by participating parent or guardian. 24h dietary recall data is analyzed with NDS-R (Nutrition Data System for Research – University of Minnesota)
6. Child’s physical activity and sedentary behavior is assessed with accelerometers (ActiGraph wGT3X-BT) used during 7 days. Accelerometer data is analyzed with ActiLife 6.11.8 (Copyright 2009-2015 ActiGraph, LLC)
7. Parent’s physical activity and sedentary behavior is assessed with the Global Physical Activity Questionnaire (GPAQ - WHO)
8. Blood pressure assessed with a digital automatic sphygmomanometer (OMRON HEM-7114EF)

Each outcome is measured at baseline and at 12 months (end of study).
Secondary outcome measures1. Environmental characteristics are assessed with a modified and adapted version of the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) Questionnaire, administered to the parent
2. Social and economic levels are assessed with an adapted version of the survey elaborated by the Social Observatory of SAIMO (Argentine Society for Research of Marketing and Opinion)

Both secondary outcomes are to be assessed at 12 months (end of study).

Target number of participantsIt was estimated that at least 200 participants were required [n=150 for the intervention group (1 cluster), and n=50 for the control group (1 cluster)]. Expecting 20% attrition, the aim was to enrol a minimum of 150 and 50 children in each cluster. Even anticipating a 60 % response rate, this was deemed feasible taking into account that more than 1000 children attended the 12 participating schools.
Participant inclusion criteriaAll 1st grade boys and girls (typically aged 6) of participating schools whose parents or guardians also agreed to participate in the study and signed the informed consent
Participant exclusion criteria1. Children with severe intellectual difficulties
2. Children with limitations to engage in physical activity
3. Children suffering from illnesses compromising nutrition or food selection
4. Children taking medication known to affect body weight
5. Parents who do not have access to internet
6. Parent with severe intellectual difficulties
