Abstract

Abstract Background The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Scoping Review Guidelines were used to conduct a scoping review of weight loss interventions for patients with prostate cancer, with the goal to ascertain the impact of these interventions on body weight, body composition, metabolic biomarkers, and prostate cancer–related outcomes. Methods Six bibliographical databases were searched. Eligible studies included articles reporting weight loss behavioral interventions with at least dietary change as an intervention component, body weight as an outcome, and interventions not solely focused on weight loss maintenance. Patients with prostate cancer of any stage were included. At least 2 independent reviewers used a data-charting form to extract study characteristics and results. Results A total of 12 studies were included. The sample consisted predominately of White patients with prostate cancer (multiple stages) in the United States. Most interventions included both dietary and physical activity components and were delivered 1-on-1 in-person and/or by telephone. Most of the studies reported that participants experienced significant weight loss and beneficial body composition changes, with a higher proportion of studies with a longer intervention period and dose (time) reporting greater magnitude of changes in outcomes. There were mixed results regarding the interventions’ impact on metabolic biomarkers and prostate cancer–related outcomes. Discussion Understanding the impact of weight loss interventions on patients with prostate cancer is important. Studies including metabolic biomarkers, prostate cancer outcomes, and more diverse populations are needed.
