This study aimed to identify factors associated with sedentary behavior in community-dwelling breast cancer survivors aged ≥50 years. 205 breast cancer survivors from the Korea National Health and Nutrition Examination Survey for this study. We used complex-sample multivariable-adjusted logistic regression analyses to analyze the associations between sociodemographic factors, medical factors, and health-related quality of life and sedentary behavior. Among the community-dwelling breast cancer survivors, 48.2% spent long sedentary time (≥7 hours/day). Insufficient aerobic exercise (OR, 2.29; 95% CI, 1.12–4.69), diabetes (OR, 3.37; 95% CI, 1.22–9.33), and unemployed status (OR, 2.29; 95% CI, 1.05–5.02) were independently associated with long sedentary time. Non-sedentary participants showed a significantly higher mean European Quality of Life 5-Dimensions (EQ-5D) index than sedentary participants after adjusting for multiple confounders (0.89 ± 0.03 vs. 0.82 ± 0.04; P = 0.001). Among the EQ-5D dimensions, problems in mobility (OR, 3.37; 95% CI, 1.42–7.98) and pain/discomfort (OR, 2.64; 95% CI, 1.24–5.63) dimensions showed positive associations with long sedentary time. In community-dwelling breast cancer survivors ≥50 years, a long sedentary time is associated with insufficient aerobic exercise, diabetes, unemployed status, and impaired quality of life. Breast cancer survivors with these factors require attention to reduce their sedentary behaviors.
