Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 30 to 46 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Study population: A sample of 800 Manitobans aged 30-46, stratified by sex, BMI, and geography are being recruited. Participants must have lived in Manitoba for a minimum of 5 years. Women who are pregnant or lactating are not eligible to participate. Additionally, because it is expected that very few of the 800 Manitobans who join TMPLR study from the general public will have reduced kidney function (eGFR <30 ml/min), 40 participants (20 female, 20 male, with no set stratification based on BMI or geography) who have severely reduced kidney function are being recruited from the renal health clinic at Seven Oaks General Hospital (Winnipeg, Manitoba).

Who may be able to join

  • Participants must have lived in Manitoba for a minimum of 5 years

Who cannot join

  • Women who are pregnant or lactating are not eligible to participate

About this study

Lifestyle factors, such as diet, physical activity and sleep, are associated with the development of many chronic diseases. The objective of The Manitoba Personalized Lifestyle Research (TMPLR) study is to understand how these lifestyle factors interact with each other and additional factors, such as an individual's genetics and gut microbiome, to influence health. This is an exploratory cross-sectional observational cohort study of adults, with extensive phenotyping by objective health and lifestyle assessments, and retrospective assessment of early life experiences, with retrospective and prospective utilization of secondary data from administrative health records. A planned non-random convenience sample of 840 Manitobans aged 30-46 recruited from the general population, stratified by sex (equal males and females), body mass index (BMI; 60% of participants with a BMI >25 kg/m2), and geography (25% from rural areas,). These stratifications were selected based on Manitoba demographics. Body composition and bone density will be measured by dual energy x-ray absorptiometry. Blood pressure, pulse wave velocity, and augmentation index will be measured on two consecutive days. Chronic disease risk biomarkers will be measured in blood and urine samples. DNA will be extracted for genetic analysis. A fecal sample will be collected for microbiome analysis.

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes and Cardiovascular Diseases, run by University of Manitoba at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 22 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was stopped early. Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent fat mass (time frame: Baseline). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03674957, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Mar 2023.
