About this trial

AGEWISE is an observational study that aims to understand how changes in gut microbiome are related to hormonal changes during women's ageing, particularly across the different stages of menopause. The study will include healthy women aged 40 to 64 years living in Portugal, who will provide stool and blood samples and complete questionnaires about their health, lifestyle, diet, and menopausal symptoms. Researchers will study the gut microbiome together with hormone levels and markers of inflammation to better understand how menopause affects long-term health and to support the development of improved prevention strategies for women.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Female sex

Aged 40 to 64 years

Resident in mainland Portugal or the islands

Able and willing to provide written informed consent

Trial population

Participants are recruited using non-random, voluntary recruitment strategies. Eligible women are identified through open public calls, institutional outreach activities, existing biobank donor databases, and re-contact of participants from related research projects who have previously agreed to be contacted for future studies. Enrollment is based on predefined eligibility criteria and the individual's willingness to participate. All potential participants who meet the eligibility criteria receive detailed information about the study from the research team, and those who agree to take part are required to provide written informed consent prior to participation.

Trial outcomes

Primary outcomes

1

Gut microbiome functional profile.

Changes in microbial gene functions and metabolic pathways derived from metagenomic analysis.

Time frame
Baseline and every 2 years over a period of 10 years.
2

Gut microbiome taxonomic composition

Changes in faecal microbiome composition assessed by shotgun metagenomic sequencing across menopause stages.

Time frame
Baseline and 2 years over a period of 10 years.

Secondary outcomes

1

Female sex hormone levels.

Blood levels of estradiol, FSH, LH, AMH, and cortisol measured by immunoassays.

Time frame
Baseline and every 2 years over a period of 10 years.
2

Inflammation biomarker levels.

Blood levels of C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-1β (IL-1β) and TNF-α.

Time frame
Baseline and every two years over a period of 10 years.
3

Menopause-related symptoms

Self-reported menopausal symptoms will be assessed via online questionnaires that include reproductive, medical history and associated symptoms.

Time frame
Baseline and every two years over a period of 10 years.
4

Nutritional data

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).

Time frame
Baseline and every two years over a period of 10 years.
