Daughters, dUdes, Mothers and othErs Fighting Cancer Together
Purpose
The purpose of this protocol is to conduct a 2-arm, single-blinded randomized controlled clinical trial (RCT) in which 56 dyads (defined as consisting of an overweight or obese cancer survivor of an obesity-related cancer and an overweight or obese "buddy" of his or her choosing) would be assigned either to a 6-month, diet- and exercise-based weight loss intervention delivered via an interactive website with tailored text messages, or to a 6-month wait-listed control group. The overall goals of the eHealth intervention are to reduce obesity and select circulating biomarkers (tumor necrosis factor alpha [TNFα], insulin, and insulin-like growth factor-1 [IGF-1]), as well as improve diet quality, physical activity, health-related quality of life (QoL), physical functioning and performance as compared to the control over the 6-month study period.

Inclusion Criteria
- Adults age 18+ for whom at least one dyad member has been diagnosed and completed curative treatment for localized renal cancer, or loco-regional ovarian, colorectal, endometrial, or female breast cancer. (Loco-regional prostate cancer survivors are also eligible but could be on active surveillance). - Diagnosed as overweight or obese (BMI >25 kg/m2. - Low vegetable and fruit intake (<2.5 cups day). - Low physical activity (<150 minutes per week). - English-speaking and writing. - Completed at least 5th grade. - Uses the internet and owns a mobile phone.
Exclusion Criteria
- Diagnosed with uncontrolled chronic conditions (i.e., diabetes, blood pressure, CVD, etc) - Diagnosed with a health conditions that precludes adherence to an unsupervised weight loss intervention (e.g., pregnancy, end-stage renal disease, etc). - Instructed by a physician to limit physical activity AND have paralysis, dementia, blindness, unstable angina, untreated stage 3 hypertension, or recent history of heart attack, congestive heart failure or pulmonary conditions that required oxygen or hospitalization within 6 months. - Diagnosed with other cancers (except non-malignant skin cancer), cancer recurrence or metastatic disease. - Resides in a skilled nursing or assisted living facility. - Resides more than 15 minute driving distance from dyad partner.

- Intervention Model Description
- We anticipate enrolling 56 dyads of participants (2 per dyad). Each dyad will be randomized to either receive the intervention for 6 months or be placed on a 6-month waitlist and offered the opportunity to try the online intervention after final assessments are completed.

Experimental Immediate Intervention Group |
Dyads randomized to the Immediate Intervention Group will receive a "Welcome Box" at completion of the baseline assessment. The Welcome Box will include two of each of the following: 1) Letters describing the project logistics and the important roles of each dyad member); 2) WiFi-enabled Scales (with instructions to weigh daily); 3) Portion Doctor ®Tableware (with instructions to use the portion plates at least once a day); 4) Fitbit® Inspire Activity Monitors (with instructions to share data with the dyad member and the study office); and 5) Instructions on how to create a secured account on the DUET website and instructions for logging on. |

Other Delayed Intervention Group |
Participants assigned to the Delayed Intervention Group will receive a "Welcome Box" which on the outside is identical (and also is comparably weighted with bottled water) to that given to the Immediate Intervention group. This box would include: 1) Letters describing the project logistics and the important roles of each dyad member; and 2) monthly online study newsletters on topics unrelated to diet and exercise, but still of interest to cancer survivors and dyad members such as coping with stress, reducing exposure to radiation, sun safety, etc. to enhance retention and will be offered the opportunity to receive the online intervention after completing final 6-month assessments. |

Detailed Description
The specific aims of this protocol are to: 1) determine whether dyads (comprised of an overweight / obese cancer survivor and an overweight / obese buddy of his or her choosing) lose significantly more weight (kg) at 6-months when assigned to the eHealth intervention compared to a wait-listed control; 2) explore between-arm differences in score changes between baseline and 6-month follow-up for other key outcomes including measures of adiposity (e.g., waist circumference [WC] and body mass index [BMI]), blood pressure, diet quality, physical activity, health-related Quality of Life (QoL), physical functioning and performance; 3) Assess the impact of the intervention on select biomarkers associated with cancer risk and progression, e.g., tumor TNFα, insulin and IGF-1; and, 4) identify predictor variables associated with program efficacy, e.g., social support, self-efficacy, risk for depression, and dyad partner (spouse, relative, friend/neighbor). Cancer survivors and their selected "buddies" who are interested in participating will be directed to a website that describes this study in detail. If interested, they will be asked to complete an online screener requiring information on race/ethnicity, gender, state of residence and eligibility criteria. Once interested participants are assessed for eligibility, consented and enrolled, they will be asked to complete online questionnaires that assess physical activity, dietary intake, health-related quality of life, risk for depression, self-efficacy, social support and barriers to diet resources. Finally, anthropometric measures, blood pressure, physical performance and circulating biomarkers will be collected in participants' homes by visiting study staff (whom the project manager will deploy after checking for a mutually convenient time for the 2-person dyad.
