About this study
Official title: Effects of Nut Consumption on Metabolic Syndrome in Korean Adults - A Randomized Controlled Dietary Intervention Trial
This study aimed to investigate the effects of nut consumption on metabolic parameters and biomarkers related to inflammation, oxidative stress, and endothelial function in Korean adults with metabolic syndrome.
Read the detailed description
A randomized, controlled, parallel, dietary intervention study was designed. Subjects with metabolic syndrome and body mass index ≥23 kg/m2 were randomized to the Nut group, which were supplemented with 30 g of mixed nuts including walnuts, peanuts, and pine nuts for 6 weeks; or allocated to the Control group. Metabolic markers were evaluated at baseline and at the end of the study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Nut groupDietary supplement
| Study group | Role | What they receive |
|---|---|---|
| Nut group | Active comparator | Subjects were supplemented with 30 g of mixed nuts including walnuts, peanuts, and pine nuts for 6 weeks Receives: Dietary Supplement: Nut group |
| Control group | No intervention | Control group maintained their usual diet without nut supplement |
What is being measured
The primary outcome is the main question the study is designed to answer.
metabolic parameters
lipid profiles, body mass index, waist circumference, blood pressure, fasting glucose, insulin, hemoglobin A1c and homeostasis model assessment of insulin resistance
Measured: 6 weeks
inflammation markers
white blood cell count, high-sensitive C-reactive protein, Interleukin-6, adiponectin, serum and urine malondialdehyde, oxidized low-density lipoprotein, vascular cell adhesion molecule (VCAM) and intercellular adhesion molecule (ICAM)
Measured: 6 weeks
Endo-peripheral artery tonometry (EndoPAT) index
EndoPAT index was assessed to evaluate endothelial function by using a finger plethysmograph based on non-invasive peripheral artery tonometry.
Measured: 6 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Nut group in people with Metabolic Syndrome, run by Ministry of Food and Drug Safety, Korea at 1 site in South Korea.
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 1 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 Dec 2013. 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 South Korea. 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?
metabolic parameters (time frame: 6 weeks). The study lists 3 primary outcomes in all. 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 NCT02023749, which also lists 1 linked publication.
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 Dec 2013.
