Remote Healthy Volunteers Research Study
Researchers at the University of South Carolina are conducting a study on chronic stress and biological aging, comparing generally healthy adults to individuals with IBS. We’re looking for generally healthy adults (e.g., no inflammatory bowel disease such as Crohn’s disease, ulcerative colitis, active H. pylori infection, etc.) to participate.

Study Background
Researchers at the University of South Carolina are conducting a study to explore the impact of chronic stress on biological aging by comparing healthy volunteers to individuals with IBS. We’re seeking healthy adults (without GI conditions like IBS, Crohn’s disease, or active H. pylori infection) to participate.
Individuals with irritable bowel syndrome (IBS) often face both physical and mental health challenges, with emerging research suggesting that chronic stress may contribute to accelerated biological aging. However, little is known about how this specifically affects those with IBS. Understanding this connection could lead to improved health outcomes for people living with IBS.
This study aims to explore the relationship between chronic stress, biological aging, and IBS to better understand these factors and their long-term effects. By participating, you can help advance knowledge that could improve health care for those with IBS and related conditions.

Additional Information
Individuals with irritable bowel syndrome (IBS) often suffer from other chronic conditions and experience poor physical and mental health. How this may impact the aging process among individuals with IBS is not well studied. A subgroup of individuals with IBS, those with varying gender identities and/or sexual orientations, may be at risk for worse health outcomes and accelerated biological aging. We are trying to better understand the relationship between chronic stress and biological aging among individuals with IBS.
You may qualify for this study if you meet the following criteria.
Inclusion Criteria:
- Ages 18-64
- Generally healthy
- Access to smartphone/computer with internet and camera
Exclusion Criteria:
- Has a gastrointestinal (GI) condition (ex. no inflammatory bowel disease: Crohn’s disease, Ulcerative Colitis, active H. pylori infection, etc.)
- Recent hospitalizations due to a psychiatric condition
If you choose to take part in this study, your participation will be completely remote and conducted from the comfort of your home. Here’s what you can expect:
- Two virtual study visits via Zoom, scheduled about 3 weeks apart
- Online questionnaires completed during study visits
- Two brief questionnaires per week between visits
- At-home sample collection of saliva (to measure telomere length, a marker of aging) and fingernail clippings (to measure cortisol, a marker of stress)
- Study materials will be mailed to you with prepaid return packaging
- Clear verbal and written instructions provided for sample collection and return
- No in-person visits required, participate from anywhere in the United States
Eligible participants may receive up to $175 for their time and effort.
There is no cost for you to participate in our research study.
