Clinical Trial Summary

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.


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.

Intervention

Dietary Supplement:
Pulse-based diet
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 diet
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.

Outcome

Type Measure Description Time frame Safety issue
Other Previous dietary consumption A validated Arabic food frequency questionnaire will be completed by all participants to evaluate previous dietary consumption of these women and compare it with dietary recommendations. Baseline point. (At the beginning of the study)
Primary Blood concentration of androgen hormone Androgen hormone; testosterone will be evaluated for all participants across the 2 study arms Change from Baseline sample at 3 months
Primary Ovarian volume An experienced ultrasonographer will evaluate the ovarian volume for each ovary. Change from Baseline ovarian morphology at 3 months
Primary Ovulatory dysfunction Assessed by measuring the duration of the menstrual cycle During nine months
Primary Lipid profile Blood Cholesterol will be evaluated for all participants across the 2 study arms Change from Baseline sample at 3 months
Primary 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 Change from Baseline measurements at 3 months
Primary 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)
Change from Baseline point at 3 months
Primary Blood pressure In mmHg.(Systolic and Diastolic) Change from Baseline Systolic Blood Pressure at 3 months
