- Brief Summary
This phase I trial tests the feasibility, acceptability, and preliminary effectiveness of online dietary and resistance training to improve physical function in older (greater than or equal to 65-years old) cancer survivors. Declines in adequate protein and calorie intake results in faster loss of muscle mass and physical functioning in older adults. A novel approach to improving physical function in older cancer survivors (OCS) is to utilize online, tailored education and counseling from registered dietitians and exercise scientists, to improve dietary intake (protein intake, diet quality) and participation in resistance exercise. The purpose of this study is to help researchers learn whether an online dietary and resistance training intervention improves diet, exercise, physical function, and health outcomes in OCS.
- Detailed Description
PRIMARY OBJECTIVES:
I. Determine the feasibility and acceptability of implementing a 12-week online dietary and resistance training randomized trial with 70 older cancer survivors.
II. Examine the preliminary efficacy of this 12-week online dietary and resistance training intervention with the intervention participants.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM 1: Patients participate in online nutritional counseling over 30 minutes in weeks 1, 3, 5, 7, 9, and 11, and participate in online resistance training sessions weekly over 30 minutes in weeks 1-6 and biweekly at weeks 8, 10, and 12. Patients also receive educational materials at baseline.
ARM 2: Patients receive educational materials at baseline.
After completion of study intervention, patients are followed up at 3 months.

- Primary Outcome Measures
Name Time Method Physical function Up to 12 weeks post study completion Measured by the Short Physical Performance Battery (SPPB) score. Efficacy will be based on 12 weeks. The SPPB score is a continuous variable, collected as the total score ranging from 0-12. Group differences in SPPB scores over the time will be tested using repeated measures analysis of variance. Using the planned contrasts command, we will investigate the changes in SPPB scores within each group, and between the intervention and control groups at end-of-study. Descriptive statistics and frequency distributions will be used to characterize the sample. To examine the effect of the intervention on the changes in physical function, a linear mixed effect model will be adopted.
- Secondary Outcome Measures
Name Time Method Technology competency At baseline and 12 weeks The 8-item eHealth Literacy Scale will measure knowledge, comfort, and perceived skills of engaging in eHealth at baseline and end-of-study. A 5-point Likert scale will be used. Change in participant outcome measures from baseline to end-of-study will be assessed using the 5-point Likert scale score.
Study adherence rate At baseline, 12 weeks, and 3-month follow-up Participants will be determined to be adherent if they attend \>= 80% of the intervention sessions (in-person meetings with study staff and online intervention sessions). Overall adherence rates and associated 95% confidence intervals will be reported.
Muscle strength At baseline, 12 weeks, and 3-month follow-up Handgrip strength will be measured in both hands using a hydraulic grip strength dynamometer. Change in participant outcome measures from baseline to end-of-study will be assessed in kilograms at the baseline and end of study visits.
Satisfaction of the delivery method and information provided by nutrition and exercise counseling sessions At 12 weeks Percentage of participant satisfaction ("satisfied" and "very satisfied") measured by a 5-item Likert-scale questionnaire
Study accrual rate Up to 9 months Will be calculated by dividing the number of potential participants that passed screening by the total number of participants started in the study after appropriate informed consent procedures.
Study retention rate At baseline and 12 weeks Will be calculated by dividing the total number of participants initiated by total number of participants in the study. Retention goal for this trial is 80%. If 80% (56/70) of participants are retained at end-of-study, the retention goal for this trial will be achieved. Overall retention rates and associated 95% confidence intervals will be reported.
Self-efficacy for improving diet quality and increasing resistance training At baseline and 12 weeks Self-efficacy will be measured via a 0-10 confidence scale rating the confidence of making exercise and diet changes, with 0 meaning not confident, 10 meaning very confident. Change in participant outcome measures from baseline to end-of-study will be assessed using the confidence scale rating.
Dietary quality and protein intake At baseline and 12 weeks Protein intake and dietary quality will be assessed by the National Cancer Institute's Diet History Questionnaire III using the Healthy Eating Index score ranging 0-100, with higher scores meaning higher diet quality. Change in participant outcome measures from baseline to end-of-study will be assessed using the Healthy Eating Index score.
Anthropometry body weight in kilograms At baseline and 12 weeks Change in participant outcome measure body weight from baseline to end-of-study will be assessed using body weight in kilograms.
Anthropometry height in inches At baseline and 12 weeks Change in participant outcome measure height from baseline to end-of-study will be assessed using height in inches.
Anthropometry measuring waist circumference in centimeters At baseline and 12 weeks Change in participant outcome measure waist circumference from baseline to end-of-study will be assessed using waist circumference in centimeters.
Resistance exercises At baseline and 12 weeks Self-reported resistance exercise will be assessed using the revised version of The Godin-Shephard Leisure-Time Exercise Questionnaire modified to specifically capture self-reported resistance exercise participation, reported in frequency of days per week and duration in minutes. Change in participant outcome measures from baseline to end-of-study will be assessed using the reported frequency of days per week and duration in minutes.
Health-related quality of life (HRQoL) physical and emotional health scores At baseline and 12 weeks RAND-36 Health Status Measure is comprised of 36 items which automatically create 8 subscales assessing multiple aspects of HRQoL. Physical and mental component summaries are created. All scores range from 0-100, with 100 as the highest. Change in participant outcome measures from baseline to end-of-study will be assessed using the RAND-36 Health Status Measure score.
