Childhood Cancer Survivors
Conditions
Brief summary
This study will look at whether motivational sessions (including regular calls with a trained health coach) in combination with time-restricted eating (TRE) is an effective way to achieve weight loss and lower cardiometabolic risk in adult survivors of childhood cancer. The researchers will look at how effective this intervention is compared to the usual approach, which is to review educational materials and measure weight once a month. This study will not provide treatment for any disease or cancer.
Interventions
Educational materials on healthy lifestyle behaviors.
Weight (kg): measured remotely via Withings Body + scale, Height, weight, waist circumference, BP, and % body fat
(14-hour fast x 2 weeks; 15-hour fast x- 1 week; 16-hour fast for the remainder of the active intervention)
Month 1-3: Bi-weekly call using motivational interviewing Months 4-6: Monthly call using motivational interviewing Support via SMS text
Questions on worry, perceived self-efficacy, health beliefs and knowledge of late effects (adapted from EQUAL study), Behavioral Risk Factor Surveillance System, Physical Activity Questionnaire, Link to Automated Self-Administered 24-Hour (ASA24) Dietary Assessment Tool with accompanying sleep module
Glucose, insulin, hemoglobin A1c, lipids. Measured remotely in the fasting state via dried blood spots in the participant's home.
