Trial summary

Obesity is increasing rapidly all over the world not only in adults but also among children. As a modifiable component of total energy expenditure (TEE) ,the amount of energy expended during physical activity plays an important role in preventing weight gain. Read more about this study

About this study

Obesity is increasing rapidly all over the world not only in adults but also among children. As a modifiable component of total energy expenditure (TEE) ,the amount of energy expended during physical activity plays an important role in preventing weight gain. Decreased physical activity, coupled with an over-consumption of calories, lead to the change of body composition by storing energy as fat.Although several studies have simultaneously examined body composition with energy expenditure the independent roles of body composition with activity energy expenditure (AEE) are less firmly established. It's suspected shrewdly that energy expenditure is partly influenced by the body composition. The aim of the study is to examine the relation of AEE with body composition in a population of school-age children.

Read the detailed description

Body composition (ie. FAT% and FFM) will be evaluated by means of bioelectrical impedance analysis (BIA) with Inbody 720 (Biospace, Seoul, South Korea). Anthropometric dimensions will be recorded for all participants according to standard procedures. Height will be recorded to the nearest 1.0mm by using a field stadiometer (Seca Corporation, Germany). FitMate metabolic system (Cosmed, Rome, Italy) will be used to estimate AEE. Subjects will be tested in a 10-minute submaximal exercise test using the FitMate systems while taking cycling test at 50 Watts on an electrically braked bicycle ergometer. Each subject will be connected to a calibrated respiratory gas analyzer, a portable metabolic analyzer designed for measurement of oxygen consumption during exercise via a face mask. Heart rate will be simultaneously measured with the use of a Cosmed wireless HR monitor to track the participant's heart rate level.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. body composition

    Each participant will be weighted while wearing light clothing, after fasting for at least 4 hours and emptying the bladder. Body composition, such as body weight, fat mass(FM), fat percentage (FAT%) and free fat mass (FFM) will be measured by bioelectrical impedance analysis(BIA) with Inbody 720 (Biospace, Seoul, South Korea).Body composition measurement will be compared between the normal weight group and overweight/obesity group.

    Measured: up to 30 days after participating in the study

Secondary outcomes (1)
  1. activity energy expenditure (AEE)

    Each participant will be asked to perform a cycling test to measure the AEE. Measurements will be recorded in the early afternoon. Total AEE (kcal) will be measured in the test. The exercise time will be adjusted by using the AEE (kcal/min), which was calculated as Total AEE/min. The weight-adjusted AEE (kcal/kg/min) will be calculated to facilitate comparisons between persons. AEE will be compared between the overweight/obesity group and normal weight group.

    Measured: up to 30 days after participating in the study

Questions about this trial

What is this clinical trial studying?

An observational study of Childhood Obesity, run by Huijuan Ruan at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

body composition (time frame: up to 30 days after participating in the study). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jul 2026.
