About this study
Official title: Examining Anti-Racist Healing in Nature to Protect Telomeres of Transitional Age BIPOC for Health Equity
The investigators will test the efficacy of our proposed intervention to reduce embodied stress in four racial/ethnic groups (Black, Latinx, Pilipinx, and Pacific Islander) as a preventative intervention for health disparities found in these communities. The intervention is comprised of two phases. The first consists of community nature walks in a pristine redwood forest for six months. This is followed by chosen nature activities with family and/or friends for three months. The investigators will test the ability of these activities in nature to reduce chronic stress that underpins many health disparities using validated biological, behavioral, and sociocultural measures. The use of these measures is in alignment with the National Institute of Minority Health and Health Disparities (NIMHD) Research Framework, and will increase understanding of individual, interpersonal, community, and social level factors that lead to, and that can eliminate health disparities.

The intervention is comprised of two phases. The first consists of community nature walks in a pristine redwood forest for six months.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Reclaiming Nature Intervention in people with Stress, Psychological and Telomere Shortening, run by Charlotte Tate at 1 site in United States.
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 4 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 28 Sep 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 United States. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Charlotte Tate, Ph.D. ((415) 338-2267, ctate2@sfsu.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Relative Telomere Length (time frame: Baseline (pre-intervention), during intervention, immediate post-intervention, 3 months after intervention). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 28 Sep 2023; AzTrials last refreshed its copy on 7 Nov 2026.
