These risks are partly related to cancer treatment exposures but are also strongly influenced by modifiable lifestyle factors such as physical activity, diet, body weight, and cardiometabolic risk factors. Although healthy lifestyle behaviors are known to reduce morbidity and mortality in this population, many adult childhood cancer survivors do not meet current lifestyle recommendations and rarely receive structured, tailored support to change health behaviors.\n\nThe Behavioral Reinforcement Intervention for Greater Health Trajectories (BRIGHT) study aims to evaluate whether a person-centered, remotely delivered lifestyle intervention can improve health-related quality of life and key health markers in adult survivors of childhood cancer with an unhealthy lifestyle. The intervention focuses on increasing physical activity and improving dietary habits through structured video-based coaching delivered by trained health promoters over a 26-week period.\n\nBRIGHT is conducted within NOPHO-CARE Sweden, a national population-based cohort of childhood cancer survivors, and uses a register-based randomized controlled design with two randomization steps. First, eligible participants are randomized to be offered the intervention or not, enabling evaluation of the population-level effect of offering the intervention through long-term register-based follow-up. Second, participants who consent to active participation are randomized to immediate or delayed start of the intervention, allowing controlled assessment of short-term intervention effects.\n\nThe primary research question is whether the BRIGHT lifestyle intervention leads to a clinically meaningful improvement in health-related quality of life, measured by the PROPr utility index derived from PROMIS-29, compared with a control period. Secondary questions address whether the intervention improves physical activity, cardiorespiratory fitness, muscle strength, diet quality, body weight, blood pressure, and cardiometabolic and biological markers, including epigenetic age acceleration. The study also examines feasibility, adherence, and scalability of delivering a person-centered lifestyle intervention within a national survivorship follow-up structure.\n\nIn addition, BRIGHT investigates whether offering the intervention to the full eligible population leads to long-term reductions in cardiovascular disease, metabolic disease, psychiatric morbidity, and mortality, using national health registers. By combining individual-level efficacy and population-level effectiveness within a single study framework, BRIGHT aims to generate robust evidence to inform future preventive care and long-term follow-up strategies for adult survivors of childhood cancer.",[73],"Survivors of Childhood Cancer",[75,76],"Lifestyle","Survivors of childhood cancer","NOT_YET_RECRUITING","2026-01-28",{"date":80,"type":81},"2026-02-03","ACTUAL",{"date":83,"type":67},"2026-05",{"date":85,"type":67},"2030-12",{"name":5,"class":6},1]
