About this study

Official title: Population Differences in the Insulin Sensitivity, Resting Energy Expenditure, and Body Composition of Overweight Children and Children of Overweight Parents

This study focuses on the way weight is gained. Individuals who gain weight primarily in their midsection (visceral weight) are at an increased risk for developing diabetes and high blood pressure.

Research has shown that African Americans suffer more often from high blood pressure, diabetes (non-insulin dependent), and heart disease than Caucasian Americans. These conditions lead to significant numbers of deaths and diseases associated with and made worse by obesity.

African American women in particular suffer from obesity and the associated conditions of obesity more than any other race or gender. However, it is unknown if the conditions seen in African American women are a result of the obesity or differences in their insulin sensitivity, glucose disposal, or fat metabolism.

This study will compare body composition, total and resting energy expenditure, and glucose disposal of obese African American and Caucasian children and of non-obese children of obese African American and Caucasian parents, to characterize the timing and nature of factors that may contribute to the prevalence of obesity and its complications.

Patients participating in this study will be followed for 15 years and be evaluated every 5 years during the study.<TAB>

Read the detailed description

African Americans have a greater prevalence than Caucasian Americans of hypertension, non-insulin-dependent diabetes mellitus, and cardiovascular disease. These conditions lead to substantial excess morbidity and mortality and are associated with and exacerbated by obesity, the prevalence of which is strikingly elevated in African American women. It is unknown if this increased prevalence of comorbid conditions is solely related to the greater prevalence of severe obesity among African American women, or due to differences in insulin sensitivity, glucose disposal, body composition, or fat cell metabolism. Through this project, we have verified that many of the physiological differences observed between African American and Caucasian adults are already present in obese children and in children at high risk for developing obesity. However, the roles that differences in energy expenditure, glucose metabolism, body composition, and other factors play in determining which children develop obesity and its comorbid conditions in adulthood remain unclear. In this study, we compare body composition, total and resting energy expenditure, and glucose disposal of obese African American and Caucasian children and of non-obese children of obese African American and Caucasian parents, to characterize the timing and nature of factors that may contribute to the prevalence of obesity and its complications. We also relate serum levels of the body-fat related circulating factors such as leptin, to these measures, and obtain samples for genomic DNA isolation from participants and their parents to characterize the roles of genes felt important for the development of obesity. We will follow these children for 15 years, studying them intensively at 5 year intervals until adulthood.

Questions about this trial

What is this clinical trial studying?

An observational study of Obesity, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) 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 9 inclusion and 0 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 23 Sep 2019. 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?

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?

Adiposity (time frame: Yearly for 15 years). 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 NCT00001522, which also lists 11 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 23 Sep 2019.
