About this study

Official title: Dairy Products and Metabolic Effects - A Multicentre Nordic Study

Foods containing more dairy fat (and thus a higher proportion of short and medium chain fatty acids and possibly some other nutrients or micronutrients with effect on energy intake, satiety or energy metabolism) affect energy balance and metabolic profile in subjects prone to develop abdominal adiposity and metabolic syndrome.

The aim of the study is to test the hypothesis that intake of dairy products has a favorable effect on markers of the metabolic syndrome.

To explore such a hypothesis the participants have to be in a free living situation during an extended study period.

Being tested
Increased intake of dairy products

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Weight

  2. Body mass index (BMI)

  3. Waist circumference/sagittal abdominal diameter

  4. Proportion of body fat (bioelectrical impedance analysis [BIA], dual energy x-ray absorptiometry [DEXA])

  5. Serum lipids (triglycerides [TG], cholesterol [chol], high-density lipoprotein [HDL] chol, low-density lipoprotein [LDL] chol, apolipoprotein (apo) B, apo A1, fatty acid composition)

  6. Blood glucose, HbA1c%

  7. Serum insulin, C-peptide

  8. Blood pressure (systolic blood pressure [SBP], diastolic blood pressure [DBP])

  9. Marker of fibrinolysis: plasminogen activator inhibitor [PAI-1]

  10. Markers for inflammation: micro C-reactive protein (microCRP), interleukin-6 (IL-6), 15-keto-DH-prostaglandin F2 alfa (in urine), fibrinogen

  11. Markers of endothelial function: vascular cell adhesion molecule (VCAM), vWillebrand factor

  12. Lipid peroxidation ("oxidative stress"): 8-F2-isoprostanes (in urine)

Secondary outcomes (9)
  1. Adiponectin, leptin

  2. LDL particle size

  3. Gene expression in leukocytes

  4. Direct measurement of insulin sensitivity

  5. Glucose tolerance test (0, 30, 60, 90, 120)

  6. Fat load test (0, 4, 6)

  7. Serum free fatty acids (FFA)

  8. Fat content of faeces

  9. Polymorphisms in genes with direct influence on relation between endogen lipid synthesis and lipid oxidation (AMP-kinase, SREBP1c, stearoyl desaturase-SCD1, acetyl-CoA carboxylase-ACC2, acyl-CoA synthetase-ACS1)

Questions about this trial

What is this clinical trial studying?

A study testing Increased intake of dairy products in people with Metabolic Syndrome X and Heart Disease, run by Oslo University Hospital at 1 site in Norway.

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 10 inclusion and 28 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 6 Jul 2011. 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 Norway. 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?

Weight. The study lists 12 primary outcomes in all. 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 6 Jul 2011.
