Abstract
BackgroundDespite being motivated to improve nutrition and physical activity behaviors, cancer survivors are still burdened by suboptimal dietary intake and low levels of physical activity. ObjectiveThe aim of this study was to assess changes in nutrition and physical activity behaviors after cancer diagnosis or treatment, barriers to eating a healthy diet and staying physically active, and sources for seeking nutrition advice reported by breast cancer survivors. DesignThis was a cross-sectional study. Participants/settingThe study included 315 survivors of breast cancer who were recruited through social media and provided completed responses to an online exploratory survey. Main outcome measuresSelf-reported changes in nutrition and physical activity behaviors after cancer diagnosis or treatment, perceived barriers to healthy eating and physical activity, and sources of nutrition advice were measured. Statistical analysisFrequency distribution of nutrition and physical activity behaviors and changes, barriers to healthy eating and physical activity, and sources of nutrition advice were estimated. ResultsAbout 84.4% of the breast cancer survivors reported at least 1 positive behavior for improving nutrition and physical activity after cancer diagnosis or treatment. Fatigue was the top barrier to both making healthy food choices (72.1%) and staying physically active (65.7%), followed by stress (69.5%) and treatment-related changes in eating habits (eg, change in tastes, loss of appetite, and craving unhealthy food) (31.4% to 48.6%) as barriers to healthy eating, and pain or discomfort (53.7%) as barriers to being physically active. Internet search (74.9%) was the primary source for seeking nutrition advice. Fewer than half reported seeking nutrition advice from health care providers. ConclusionsDespite making positive changes in nutrition and physical activity behaviors after cancer diagnosis or treatment, breast cancer survivors experience treatment-related barriers to eating a healthy diet and staying physically active. Our results reinforce the need for developing tailored intervention programs and integrating nutrition into oncology care.
