Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This is an investigation of possible relationships between daily physical activity (PA) and different measurements of fatigue in cancer survivors participating in a cancer exercise program. Results will inform exercise prescription and timing to best reduce fatigue, as well as methodology for measuring fatigue. Participants will answer several daily questions on fatigue using a smartphone application during the 3 month exercise program and wear a PA monitor for 10 days during the first month and last month of the program.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

We will enroll 50-150 cancer survivors participating in the BfitBwell Cancer Exercise Program. As this is a non-invasive, exploratory observational investigation, there are minimal inclusion and exclusion criteria.

Description

Inclusion Criteria:

  • Be an active participant in the BfitBwell Cancer Exercise Program
  • Criteria for this program include:
  • Adult (>= 18 years old)
  • Being a patient seen at the University of Colorado Cancer Center
  • Currently receiving cancer therapy or be within 6 months of completing cancer therapy
  • Have a signed physician clearance form to participate in an exercise program
  • Have a smartphone (necessary for the EMA assessments)
  • A score of 48 or less on the FACIT-Fatigue (completed during the initial BfitBwell Program assessment)
  • The minimally important difference of the FACIT-Fatigue is 3 points, suggesting that a score of at most 48 indicates the presence of CRF and allows for meaningful change in both directions.

Exclusion Criteria:

  • None

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
BfitBwell Participants
Individuals in the BfitBwell Cancer Exercise Program complete a FACIT-Fatigue questionnaire at their baseline assessment. This will be screened for all incoming BfitBwell participants and those meeting the inclusion criteria of a score of 48 or less will be approached for interest in participating. The primary research activities beyond recruitment, screening, and informed consent are the collection of EMA fatigue assessments via smartphone application and PA assessment via actigraphy.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
10-point Fatigue Scale, Day
Time Frame: 3 months
Severity of fatigue experienced over the course of the day, ranked 0-10. How would you rate your fatigue, over the last day, on a scale of 0-10, with 0 being no fatigue and 10 being the worst possible fatigue?
3 months
Physical Activity measure by Actigraph device
Time Frame: 3 months
PA will be monitored using commonly used, non-invasive Actigraph devices (Actigraph GT3XP). Data will be collected utilizing methodology similar to that of the National Health and Nutrition Examination Survey (NHANES), in cancer survivors. The collected accelerometry data will be downloaded and analyzed in ActiLife software, calculation the average time spent in moderate-to-vigorous (MVPA) at each assessment period using standard algorithms and cut-points.
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Physical assessment measures from BfitBwell Program
Time Frame: 3 months
As all participants are recruited from active members of BfitBwell Cancer Exercise Program, additional data will be extracted from program documents which are regularly administered and collected by the BfitBwell Program. Administration/collection will not change for study participants. Physical assessment measures are obtained from a physical assessment and electronic questionnaire.
3 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Response Rate to EMA assessments
Time Frame: 3 months

Measures of fatigue are collected electronically. Tools utilized to collect these outcomes: REDCap and the LifeData smartphone application.

  • REDCap: REDCap is a secure, university supported and approved data collection tool. Links to complete the standardized questionnaires of fatigue (FACIT-Fatigue and MFI) will be emailed to participants with regular reminder emails sent daily until completed.
  • LifeData: LifeData is a secure research platform used by previous research studies involving EMA (https://www.lifedatacorp.com/customer-publications/). The application will send a smartphone notification to collect data at random timepoints in predefined windows, and allow participants to self-initiate data entry. Participants will not enter any identifying information and will instead be assigned a de-identified research IDd. Linking documentation of participant to this ID will be stored solely on university servers. LifeData will be utilized to collect the EMA assessments of fatigue.
