Обзор

The main aim of this study is to evaluate the effect of equol on menopausal symptoms of women. Our hypothesis is that equol producers will have milder menopausal symptoms compared to non-equol producers. Equol is known as a metabolite produced by gut microbiota from soy-related diet and has estrogen-like activity compared to the isoflavones from soybean. Previous studies have shown that some women can produce equol from soy-related diet, but the others cannot because they don't have the bacteria which can metabolite daidzein in gut even if they take isoflavones thorough soybean products. This study will involve participants consuming a soy protein bar and collection of urine samples before and after its consumption.

Подробное описание

Day 0 - Recruitment and consent taking. Height, weight and blood pressure would be measured. Patients will also fill up questionnaires on basic demographics, menopausal symptoms (Menopause Rating Scale and Vulvovaginal Symptom Questionnaire), Food Frequency Questionnaire for Soy intake, International Physical Activity Questionnaire.

Day 1 - Collect first morning urine between 5ml to 10 ml in the pre-labelled (will not contain identifiers but only assigned study subject number) containers provided. Store the urine sample in cool place in room temperature and dispatch to site after the second sample has been collected. To consume a soy based protein bar provided by study after dinner on day 1.

Day 2 - Collect first morning urine between 5ml to 10 ml in the pre-labelled(will not contain identifiers but only assigned study subject number) containers provided. Double bag the containers and call courier to dispatch urine to KK Women's and Children's Hospital.

All urine samples received will be immediately frozen and stored in KKH in a freezer. The samples will be couriered to Saga Nutraceuticals Research Institute, Otsuka Pharmaceutical Co. Ltd, Japan in batches for analysis of urinary equol concentration. Clinical Trials Agreement has been executed between Otsuka Pharmaceutical Co. Ltd, Japan and KK Women's and Children's Hospital.
