Genetics, Metabolism and Weight Loss in Older, Obese Veterans
A study testing Weight Loss in people with Obesity, run by US Department of Veterans Affairs at 1 site in United States.
Trial summary
This study is designed to determine whether sequence variation in the lipoprotein lipase (LPQ) gene affects the amount of weight loss and metabolic responses during a hypocaloric diet treatment for overweight and obese (BMI=25-35 kg/m2), older (50-65 yrs), sedentary veterans.

About this study
This study is designed to determine whether sequence variation in the lipoprotein lipase (LPQ) gene affects the amount of weight loss and metabolic responses during a hypocaloric diet treatment for overweight and obese (BMI=25-35 kg/m2), older (50-65 yrs), sedentary veterans.
Read the detailed description
Veterans who are 50-65 yrs, non-smoking, sedentary and weight stable with a BMI between 25-35 kg/m2 (120-150% desirable body weight) are recruited and screened via telephone, medical history, and physical exam. Exclusion criteria are: diabetes, hypertriglyceridemia (>400 mg/dl), history of cancer or myocardial infarction, clinical depression, renal, liver or hematologic disease, and medications that affect glucose or lipid metabolism (thiazides, estrogen replacement, beta-blockers). Changes in total and visceral body fat are measured by dual x-ray absorptiometry and computerized tomography, resting energy expenditure and fat oxidation rate by indirect calorimetry, and lipoprotein lipids by enzymatic assay. Glucose tolerance is assessed during a three-hour oral glucose tolerance test with measurement of glucose- and insulin levels every 30 minutes. LPL activity is measured in 3050mg pieces of subcutaneous abdominal and gluteal adipose tissue.

The sponsor lists 0 inclusion and 6 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 21 Jan 2009. 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.
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 21 Jan 2009.
