About this study
Official title: Modeling the Epidemiologic Transition: Energy Expenditure, Obesity and Diabetes
This project examines whether individuals' amount of activity energy expenditure (AEE) is related to adiposity and adiposity/diabetes-related hormones in a diverse sample of 2500, and to test the ecological hypothesis that a decline in levels of AEE is an important cause of the increases in obesity that are currently taking place in many societies.
One goal is to use doubly labeled water and/or accelerometers to objectively measure activity energy expenditure in community samples from five adult populations across the spectrum of obesity risk. From each site, (i.e., Ghana, South Africa, Seychelles, Jamaica, and the US), 500 black adults will be recruited. Among all participants, AEE will be measured using accelerometers and in a subset of 75 per site, AEE will also be measured by doubly labeled water.

The doubly labeled water sample will be used to confirm site-specific concordance with the accelerometer measurements and to estimate population mean levels of AEE. Additionally, body composition, dietary intake, fasting glucose, insulin, adiponectin, leptin and ghrelin will be measured. The relationships between calories expended in activity and body composition, dietary intake, glucose, hormones and adipocytokines, both within and between each population using doubly labeled water and accelerometers will be examined. In this longitudinal study, weight will be measured at 12 and 24-months, and AEE by accelerometer will be assessed at enrollment and again at 2-years of follow-up; associations between change in AEE and change in weight will be estimated.
The central purpose of this project is to test whether AEE or change in AEE can be identified as a contributory mechanism to population-wide weight gain and, if so, to quantify its importance. In addition, we seek to understand the interrelationships between the adipocytokines and the hormones ghrelin and insulin as well as AEE in the regulation of body weight across the continuum of body mass indices (BMI) represented by these five populations.
Read the detailed description
Populations all over the world are experiencing rapid increases in the prevalence of obesity and diabetes. To date, the public health response to the emerging obesity epidemic has been almost totally ineffective. As a first line of response, professional bodies and government organizations have issued prevention guidelines, all of which include recommendations on levels of activity energy expenditure (AEE). However, even if fully implemented, it is not clear that the current recommendations on AEE would impact the trend in age-related weight gain. In fact, there is virtually no direct evidence that can be brought to bear on the question of whether the obesity epidemic has resulted primarily or even partially from society-wide declines in habitual physical activity (PA).
To date, epidemiologic research on AEE has relied on very crude measurement tools-primarily questionnaires. These self-reported data capture only a small fraction of the total variance in activity and are potentially confounded when they focus on leisure-time PA. By contrast, direct measurement with doubly labeled water (DLW) provides a precise, unbiased estimate of all forms of non-resting energy expenditure. DLW has also been used to validate the new generation of accelerometers which are efficient measurement tools for larger studies.
In this study, objective measurement tools will be used to examine the "ecology of AEE". This study will take place in 5 countries spanning the range of the activity-obesity spectrum and will combine both within-population person-level and between-population ecological analyses. First, the study will examine whether an individual's amount or pattern of AEE is related to adiposity in a diverse sample of 2,500. Second, the study will evaluate whether a decline in levels of AEE is an important cause of the rapid increases in obesity that currently take place in many societies. As an exploratory aim we will examine the role of selected adipocytokines and the appetite hormone ghrelin.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This project examines whether individuals' amount of activity energy expenditure (AEE) is related to adiposity and adiposity/diabetes-related hormones in a diverse sample of 2500, and to test the ecological hypothesis that a decline in levels of AEE is an important cause of the increases in obesity that are currently taking place in many societies.
One goal is to use doubly labeled water and/or accelerometers to objectively measure activity energy expenditure in community samples from five adult populations across the spectrum of obesity risk. From each site, (i.e., Ghana, South Africa, Seychelles, Jamaica, and the US), 500 black adults will be recruited. Among all participants, AEE will be measured using accelerometers and in a subset of 75 per site, AEE will also be measured by doubly labeled water.
The doubly labeled water sample will be used to confirm site-specific concordance with the accelerometer measurements and to estimate population mean levels of AEE. Additionally, body composition, dietary intake, fasting glucose, insulin, adiponectin, leptin and ghrelin will be measured. The relationships between calories expended in activity and body composition, dietary intake, glucose, hormones and adipocytokines, both within and between each population using doubly labeled water and accelerometers will be examined.

Questions about this trial
What is this clinical trial studying?
An observational study of Obesity and Diabetes, run by Loyola University at 1 site in United States.
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 2 inclusion and 2 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 17 Sep 2025. 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 United States. 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?
Yes. Results are posted in the registry (first posted 17 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Change in Body Weight (time frame: 24 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02925156, which also lists 12 linked publications.
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 17 Sep 2025.
