Study summary

There is a critical need for physical activity interventions in colorectal cancer (CRC). The investigators have developed a digital health physical activity intervention, Smart Pace, which includes a wearable tracker (Fitbit) and text messaging and aims to have patients build up to 150 min/wk of moderate activity. In this study, the investigators propose to expand and improve Smart Pace, including: 1) enrolling patients during chemotherapy; 2) tailoring text messages to individual preferences and treatment timing; and 3) adding resources to support home-based exercise. The study is a 12-week pilot randomized controlled trial (RCT) to evaluate the feasibility of this novel digital health physical activity intervention among 48 CRC patients on chemotherapy. The specific aims are to: 1) Determine the feasibility of the intervention via adherence and attrition, and determine the acceptability of the intervention via questionnaires and semi-structured interviews . 2) Estimate the effect of the intervention vs. usual care on physical activity, QOL, and symptoms at 12-weeks . And 3) Explore the impact of the intervention vs. usual care on fitness, weight, waist circumference, and blood pressure at 12-weeks.

What researchers measure

Primary outcomes

  1. Fitbit wear time

    Number of study days Fitbit is worn

    Time frame: up to 12 weeks from study start

  2. Acceptability of the intervention

    Acceptability will be assessed with an investigator created questionnaire among participants in the intervention arm.

    Time frame: At 12 weeks from study start

  3. Text message response rate

    Time frame: up to 12 weeks from study start

Secondary outcomes

  1. Objective physical activity

    Minutes of moderate-to-vigorous physical activity per week measured by accelerometer

    Time frame: At 0 weeks and 12 weeks from study start

  2. Fatigue

    Lee Fatigue Scale

    Time frame: At 0 and 12 weeks from study start

  3. Cardiorespiratory fitness

    6 minute walk test

    Time frame: At 0 and 12 weeks from study start

  4. Anthropometrics, Waist circumference

    Time frame: At 0 and 12 weeks from study start

  5. Anthropometrics, Body weight

    Time frame: At 0 and 12 weeks from study start

  6. Sleep quality

    Will be assessed by the Pittsburgh Sleep Quality Index, providing a score ranging from 0 to 21, where lower scores denote a healthier sleep quality.

    Time frame: At 0 and 12 weeks from study start

  7. Health-related quality of life in cancer patients

    Will be assessed via the European Organization for Research and Treatment (EORTC) of Cancer Quality of Life Questionnaire-Core 30

    Time frame: At 0 and 12 weeks from study start

  8. Health-related quality of life in colorectal cancer patients

    Will be assessed via the European Organization for Research and Treatment (EORTC) of Cancer Quality of Life Questionnaire-Core 29

    Time frame: At 0 and 12 weeks from study start

  9. Neuropathy

    Will be assessed by the Chemotherapy-Induced Peripheral Neuropathy 20 (CIPN20) questionnaire, a 20-item quality of life questionnaire.

    Time frame: At 0 and 12 weeks from study start

  10. Anxiety
