About this study

Official title: A Comparison of a Pulse-Based Diet and the Therapeutic Lifestyle Changes Diet on Reproductive and Metabolic Parameters in Women with Polycystic Ovary Syndrome

The main objective of the study is to evaluate the effectiveness of a lifestyle program for women with Polycystic Ovary Syndrome (PCOS). The investigators want to assess the efficacy of a pulse-based diet (i.e. a diet that contains lentils, chick-peas, and beans) on the clinical features, biochemical, and hormonal parameters of PCOS compared to the healthy therapeutic lifestyle changes diet.

Read the detailed description

The main objective of the study is to identify the effect of pulses on a range of PCOS and metabolic syndrome features. In this parallel clinical trial, 110 (18-35 years old) women with PCOS will be recruited. Participants will be randomly assigned to either a pulse-based diet or a therapeutic lifestyle changes-based diet. The effect of a pulse-based diet on a range of reproductive and metabolic parameters will be evaluated. The results of this study are anticipated to evaluate the therapeutic merits of a pulse-based diet for women with PCOS which would influence dietary guidelines.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pulse-based dietDietary supplement

    An isocaloric, balanced diet with a fixed macronutrient composition of 28% fat, 55% carbohydrate, and 17% protein.

    The pulse diet will include two pulse-based meals; each pulse meal will be consisted of about one cup of non-oil seed pulses, different varieties of pulses (dried beans, peas, lentils, lupine and chickpeas) will be used.

  • TLC dietDietary supplement

    An isocaloric, balanced diet with a fixed macronutrient composition of 28% fat, 55% carbohydrate, and 17% protein.

    The healthy TLC diet will be tailored for each participant according to their energy levels in order to achieve the following amount of nutrients: less than 7% of total calories of saturated fatty acids, up to 10% of total calories of polyunsaturated fat, up to 20% of total calories of monounsaturated fat, less than 200 mg a day of cholesterol, at least 5 to 10 grams a day of soluble fiber.

Pulse-based dietExperimentalThe pulse diet will include two pulse-based meals; each pulse meal will be consisted of about one cup of non-oil seed pulses, different varieties of pulses (dried beans, peas, lentils, lupine, and chickpeas) will be used. Varieties of pulses will be included and the participants will be provided with recipes and preparation ideas, which would enhance the palatability of pulses, give different taste choices, and ease the follow of the prescribed diet and encourage the participants to consume it for the target duration. The diet is isocaloric and balanced with a fixed macronutrient composition of 28% fat, 55% carbohydrate, and 17% protein.
Receives: Dietary Supplement: Pulse-based diet
TLC dietPlacebo comparatorTLC group will be provided with instructions to follow the TLC guidelines and a sample diet plan will be individualized for each participant. The healthy TLC diet will be tailored for each participant according to their energy levels in order to achieve the following amount of nutrients: less than 7% of total calories of saturated fatty acids, up to 10% of total calories of polyunsaturated fat, up to 20% of total calories of monounsaturated fat, less than 200 mg a day of cholesterol, at least 5 to 10 grams a day of soluble fiber.

What is being measured

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

  1. Blood concentration of androgen hormone

    Androgen hormone; testosterone will be evaluated for all participants across the 2 study arms

    Measured: Change from Baseline sample at 3 months

  2. Ovarian volume

    An experienced ultrasonographer will evaluate the ovarian volume for each ovary.

    Measured: Change from Baseline ovarian morphology at 3 months

  3. Ovulatory dysfunction

    Assessed by measuring the duration of the menstrual cycle

    Measured: During nine months

  4. Lipid profile

    Blood Cholesterol will be evaluated for all participants across the 2 study arms

    Measured: Change from Baseline sample at 3 months

  5. Change in fat mass

    Body composition scan using InBody 120 (the body composition analyzer) will be evaluated for all participants across the 2 study arms

    Measured: Change from Baseline measurements at 3 months

  6. Physical activity

    The validated Arabic short form of the International Physical Activity Questionnaire (IPAQ) will be used to evaluate physical activity of all participants. And an overall total physical activity MET-minutes/week score can be computed as: Total physical activity MET-minutes/week = sum of Total (Walking + Moderate + Vigorous) MET- minutes/week scores.

    ( < 4 : Low), (4-6 Moderate) and ( >6: Vigorous)

    Measured: Change from Baseline point at 3 months

  7. Blood pressure

    In mmHg.(Systolic and Diastolic)

    Measured: Change from Baseline Systolic Blood Pressure at 3 months

What does the primary outcome measure?

Blood concentration of androgen hormone (time frame: Change from Baseline sample at 3 months). The study lists 7 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 NCT05428566, which also lists 35 linked publications.

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 1 Nov 2024.
