Plain English Summary

Background and study aims
Obesity in children has become an epidemic in developed and developing countries because it is the leading cause of morbidity and premature mortality. A randomized controlled trial was conducted to test the effect of a family-based lifestyle intervention program on body mass index, dietary habits, and physical activity for obese children aged 6-9 years in Jordan.

Who can participate?
Children aged 6-9 years who are obese and have a sedentary lifestyle.

What does the study involve?
Participants will be randomly allocated to receive a three-month family-based lifestyle intervention program on body mass index (BMI), dietary habits, and physical activity for obese children aged 6-9 years in Jordan, or no intervention.

What are the possible benefits and risks of participating?
There should be direct benefit to the student participant from this study, as it will raise awareness of a healthy lifestyle change, and provide information that may prevent you long-term from developing any complications related to obesity.
There are no further risks or discomforts anticipated from participation.

Where is the study run from?
Alzaytoonah University of Jordan and four schools in Amman (Jordan)

When is the study starting and how long is it expected to run for?
May 2020 to September 2020

Who is funding the study?

Obesity in children


A two-group, single-blinded, randomized controlled trial study will be conducted at Amman city, at four schools. The students will randomly be allocated to intervention group to receive a family-based lifestyle intervention program or control group with no care. All participants will be followed for three months.

Four schools were selected randomly using a cluster sampling method. Then, two schools were selected randomly to be in the intervention arm and the other two schools were selected to be in the control arm. Sequentially, the researchers reviewed the students’ health records that are existed in these schools. The eligible students and caregivers (guardians and parents) who were willing to participate will be provided with consent forms, and children gave assent. Thereafter, the researchers randomly will pull out the names of potential participants who met the inclusion criteria to be either in intervention group or in control group. The file names will keep concealed in closed envelopes. All subjects were blinded to their allocations.

The intervention is a lifestyle teaching program. The program consists of encouraging children to select a healthy diet and increase PA. The intervention was originally adopted from a 'Swap It Don't Stop It' (SIDSI) program (originally developed by the Australian government), which was culturally adapted and modified by Bani Salameh and had been tested on Jordanian adolescents in 2012-2013. Participants will deliver the modified version.
Those children and their parents will be educated about interventional behavioral approaches to increase PA to around 7 hours per week and to decrease sedentary lifestyle, such as screen games and watching television, to less than 14 hours per week. Behavioural methods included lifestyle changes, self-control, SIDSI weekly and monthly established targets, and positive reinforcement to achieve planned goals. Other instructions such as promoting body image and reducing emotional eating will be also provided.
The program will be delivered over 3 months in the schools' auditorium. A letter of invitation to parents, whose cooperation and understanding was vital, will be sent out with the participants three days before each session. Children and their parents attended the fortnightly sessions at the schools after the school classes were over. The program consisted of six group sessions (30 minutes fortnightly and 10-12 participants in each one), which will be followed by a phone call for reassurance if needed. The participants and their parents in each group will offer complementary education materials, such as manual of the daily diet and PA.

Primary outcome measure

Body Mass Index will be measured by calculating height (m) and body weight (kg) at baseline and 3 months. Body mass index z-scores or BMI standard deviation (S.D) scores, which are considered as measures of child' weight according to age and sex. Also, body mass index percentile, which is a measure of weight according to child's age. It will be classified as follows: underweight (BMI is less than 5th percentile), normal weight (BMI is 5th - (BMI is 5th -85th percentile, overweight (BMI is at or above the 85th percentile but less than 95th percentile), and obesity (BMI is at or above the 95th percentile). The height and weight will be measured based on the guidelines provided by WHO. Children will be weighed without shoes in daily or routinely light clothes using, a digital scale (Garmin Index Smart Scale). A fixed height board will be used for height measurements.

Secondary outcome measures

Dietary habits and physical activity assessed by a questionnaire consists of questions related to dietary habits (seven questions) and physical activity (nine questions) at baseline and 3 months
