About this study
Official title: The Influence of Vitamin D Receptor (VDR) Gene Polymorphisms (BsmI, TaqI, ApaI, FokI) on Weight Loss by Diet and Exercise Interventions in Non-diabetic Overweight and Obese Subjects
This is a six months intervention study in non-diabetic overweight and obese subjects. Subjects will be counseled for weight loss through diet and exercise. Diet and exercise will be recommended as per the regular norms for weight loss (weight loss ≥10% from baseline weight will be considered as a significant loss of weight) for overweight and obese subjects. A sample size of 90 subjects was calculated but assuming a drop out rate of 20%, 110 subjects will be enrolled. Enrolled subjects will be measured at every visit (monthly) for weight, body composition measures of abdominal obesity and skin folds. They would be assessed for compliance with diet and exercise. Detailed analysis of body composition including DXA, biochemical analysis will be performed at enrollment and after six months intervention. Statistical analysis will be performed to find association between measures of body composition for weight loss and genotypes of the VDR polymorphisms.

VDR Polymorphisms
Polymorphisms in the VDR gene have been identified through out the complete VDR gene region and associated with cancer and autoimmune diseases. The FokI polymorphism is present in the translation site and results in the VDR protein being shortened by three amino acids and is not linked with any other VDR polymorphisms. This polymorphism predisposes to bone-disease, risk of cancer, immune mediated diseases 147-149,150, 151.
The common VDR gene polymorphisms are BsmI, TaqI, ApaI and FokI. These polymorphisms have shown varying results with insulin sensitivity and secretion.

Questions about this trial
What is this clinical trial studying?
A study testing diet and exercise in people with Overweight and Obesity, run by Diabetes Foundation, India at 1 site in India.
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 8 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 4 Feb 2021. 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 India. 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 weight (Kg) (time frame: 6 months). 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 4 Feb 2021.
