AGEWISE: Unravelling the Gut-Hormone Axis in Women's Ageing
Přehled studie
Postavení
Detailní popis
AGEWISE aims to investigate the relationship between the gut microbiome, female sex hormones, chronic low-grade inflammation, and women's ageing across the menopausal transition.
The results will support the identification of microbiome-based and blood-based biomarkers associated with menopause and ageing, and contribute to the development of data-driven tools for personalised risk assessment and prevention strategies in women's health.
Primary Objective:
To identify and validate faecal microbiome biomarkers by analysing taxonomic and functional changes across different stages of menopause in women.
Secondary Objectives:
To explore associations between gut microbiome composition and female sex hormone levels, including estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Müllerian hormone (AMH), and cortisol.
To investigate the relationship between the gut microbiome and blood biomarkers of chronic low-grade inflammation (inflammaging).
To assess associations between microbiome profiles, clinical history, lifestyle, and dietary factors and the risk of conditions associated with menopause.

Popis opatření |
Časové okno |
|---|---|---|
|
Female sex hormone levels.
Časové okno: Baseline and every 2 years over a period of 10 years.
|
Blood levels of estradiol, FSH, LH, AMH, and cortisol measured by immunoassays.
|
Baseline and every 2 years over a period of 10 years.
|
|
Inflammation biomarker levels.
Časové okno: Baseline and every two years over a period of 10 years.
|
Blood levels of C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-1β (IL-1β) and TNF-α.
|
Baseline and every two years over a period of 10 years.
|
|
Menopause-related symptoms
Časové okno: Baseline and every two years over a period of 10 years.
|
Self-reported menopausal symptoms will be assessed via online questionnaires that include reproductive, medical history and associated symptoms.
|
Baseline and every two years over a period of 10 years.
|
|
Nutritional data
Časové okno: Baseline and every two years over a period of 10 years.
|
Self-reported dietary intake will be assessed via telephone interview through two 24-hour recalls, following protocols validated by the Portuguese National Food and Physical Activity Survey (IAN-AF).
|
Baseline and every two years over a period of 10 years.
|
|
Effect of physical activity on gut microbiota composition
Časové okno: Baseline and every two years over a period of 10 years.
|
Physical activity will be assessed using International Physical Activity Questionnaire - Short Form a validated tool composed of 7 questions covering the last 7 days of physical activity across three intensity levels which allows classification of participants into three activity levels: low, moderate, or high.
|
Baseline and every two years over a period of 10 years.
|
|
Effect of sleeping habits on gut microbiota composition
Časové okno: Baseline and every 2 years over a period of 10 years.
|
Sleeping habits will be assessed by the Pittsburgh Sleep Quality Index (PSQI), a validated questionnaire that consists of 19 items which are distributed into seven "components": subjective sleep quality; sleep latency; sleep duration; habitual sleep efficiency; sleep disturbances; use of sleeping medication; day-time dysfunction.
Each component is scored from 0 to 2, and the sum of the component scores yields a global PSQI score.
A global PSQI score ≥6 will indicate poor sleep quality.
|
Baseline and every 2 years over a period of 10 years.
|
|
Effect of stress levels on gut microbiota composition
Časové okno: Baseline and every 2 years over a period of 10 years.
|
Stress levels will be assessed by the Perceived Stress Scale, a validated questionnaire composed of 10 questions.
Individual scores on the PSS can range from 0 to 40 with higher scores indicating higher perceived stress.
Scores ranging from 0-13 will be considered low stress, 14-26 will be considered moderate stress and scores ranging from 27-40 will be considered high perceived stress.
|
Baseline and every 2 years over a period of 10 years.
