Study summary

The aim of this study is to determine the effect of 6 weeks supplementation of oleuropein on individuals diagnosed with metabolic syndrome. The baseline and end biochemical parameters and anthropometric measurements will be compared with control subjects.

Read the detailed description

This study was conducted to investigate the effect of adding oleuropein to the medical nutrition therapy of individuals with metabolic syndrome on their anthropometric measurements and biochemical parameters.

Sub-objectives of the study;

Determining the presence of inflammation in patiens with metabolic syndrome Determination of the effect of diet and diet combined with oleuropein on both fasting blood glucose, insulin and blood lipid profile.

Determination of both anti-inflammatory and antidiabetic effects of oleuropein. Determination of the effect of diet and diet combined with oleuropein on anthropometric measurements.

The aim of this study is to compare the anthropometric measurements and biomarkers of patients with metabolic syndrome as a result of the medical nutrition therpy with consumption of olive leaf extract (2 times a day) that has been contain 100 mg oleuropein for 6 weeks.

What researchers measure

Primary outcomes

  1. Change from Baseline in the Fasting Blood Glucose (mg/dl) at 6 weeks

    The fasting blood glucose (mg/dl) at the baseline and 6 weeks later noted from the routinely requested tests in the hospital. These values recorded for all groups.

    Time frame: 6 weeks

  2. Change from Baseline in the Insulin (uU/mL) at 6 weeks

    The fasting blood glucose (mg/dl) at the baseline and 6 weeks later noted from the routinely requested tests in the hospital. These values recorded for all groups.

    Time frame: 6 weeks

  3. Change from Baseline in the Triglyceride (TG) (mg/dl), high density lipoprotein (HDL-C) (mg/dl), low density lipoprotein (LDL-C) (mg/dl), Total Cholesterol (mg/dl) at 6 weeks

    Triglyceride (TG) (mg/dl), high density lipoprotein (HDL-C) (mg/dl), low density lipoprotein (LDL-C) (mg/dl), Total Cholesterol (mg/dl) at the baseline and 6 weeks later noted from the routinely requested tests in the hospital. These values recorded for all groups.

    Time frame: 6 weeks

  4. Change from Baseline in the HOMA-IR at 6 weeks

    The fasting blood glucose (mg/dl) and fasting insulin (mU/L) values of the individuals with metabolic syndrome at the baseline and 6 weeks later noted from the routinely requested tests in the hospital. HOMA-IR calculated with the formula (fasting glucose (mg/dl) x fasting insulin (mU/L)) / 405. These values recorded for all groups.

    Time frame: 6 weeks

  5. Change from Baseline in the BMI (kg/m2)

    The body weight (kg) and height (m) of the individuals with metabolic syndrome were measured at the baseline and again after 6 weeks by the researcher, who noted the values in their files. The height of the patients was measured with a fixed height meter at 0.5 cm intervals, with shoes off. For body analysis, an 8-electrode bioelectrical impedance (BIA) device, Inbody 270, which performs segmental analysis, was used. Patients were asked to remove all metal items (rings, earrings, bracelets, watches, phones, etc.), any heavy clothing, shoes, and socks before stepping on the device. The device was set to -1.0 kg to account for the remaining clothes. From these measurements, body weight, body fat (kg), body fat percentage (%), body muscle (kg), and body water (kg) values were recorded. Body mass index (BMI) was calculated as weight (kg) divided by height (m) squared.

    Time frame: 6 weeks

  6. Change from Baseline in the Anthropometric Measurements

    The anthropometric measurements of the individuals with metabolic syndrome at the baseline and 6 weeks taken by the researcher and noted in their files. These measurements included waist circumference (cm), hip circumference (cm), mid-upper arm circumference (cm), waist-to-height ratio (cm), and waist-to-hip ratio (cm). Waist circumference was measured using an inflexible tape at the umbilicus level after normal exhalation to the nearest 0.1 cm. Hip circumference was measured from the widest area between the waist and the thigh. The waist-to-hip ratio was calculated using the formula waist (cm)/hip (cm), and the waist-to-height ratio was calculated using the formula waist (cm)/height (cm). Mid-upper arm circumference was measured on the left arm of the patients. Neck circumference was measured with the shoulders in a free position from the point where the thyroid cartilage was most protruding.

    Time frame: 6 weeks
