AGEWISE Study on Gut Microbiome and Hormonal Changes in Women Aged 40 to 64 During Menopause

What this Trial Is About

Researchers are studying how changes in the gut microbiome relate to hormonal changes during womens ageing, especially throughout menopause. This observational study focuses on healthy women aged 40 to 64 living in Portugal. It aims to understand how menopause affects long-term health by examining gut microbiome, hormone levels, and markers of chronic low-grade inflammation, to help develop better prevention strategies for womens health. Participants are grouped by menopausal stage premenopausal with regular periods, perimenopausal with irregular periods and some menopausal symptoms, and menopausalpostmenopausal with no menstruation for 12 months. Women will provide stool and blood samples and complete questionnaires about their health, lifestyle, diet, and menopausal symptoms. The study collects data over 10 years, with baseline and follow-up assessments every two years. During the study, participants will be assessed for gut microbiome composition and function, hormone levels, inflammation markers, menopause-related symptoms, nutrition, physical activity, sleep habits, and stress levels. These evaluations help researchers identify microbiome and blood biomarkers linked to menopause and ageing. Participation involves regular sample collection and questionnaires, with ongoing monitoring to support personalized risk assessment and prevention in womens health.
