Needs, preferences, and experiences of adult cancer survivors in accessing dietary information post-treatment: A scoping review

Introduction To support provision of healthy lifestyle information tailored to patients' needs and preferences, this review maps adult cancer survivors' self-reported needs, preferences, and experiences accessing dietary information post-treatment. Methods A scoping review of research published within the past decade conducted using PRISMA-ScR guidelines. Seven databases were searched in June 2020. Results Of 15,973 articles identified, 57 met eligibility criteria. Studies most frequently included survivors of breast cancer (49%), persons aged 40+ years (95%), <= 5 years post-diagnosis (54%), and residing in North America (44%). Cancer survivors commonly identified needing information regarding healthy eating, particularly practical skills, and support in changing dietary behaviours. Preferences included specific recommendations, direct communication with healthcare professionals, and peer support from other cancer survivors. In practice, survivors frequently reported receiving generic advice from healthcare professionals, limited dietary follow-up, and lack of referral to support. Unmet needs in healthcare settings led to dietary information-seeking elsewhere; however, survivors indicated difficulty identifying credible sources. Personal beliefs and desire for involvement in care motivated dietary information-seeking post-treatment. Conclusion Cancer survivors' experiences accessing dietary information post-treatment do not align with needs and preferences. Less is known about survivors who are young adults, >5 years post-diagnosis, and living in rural areas.
