AbstractThis study aimed to compare health-promoting behaviors between middle-aged breast cancer survivors and matched non-cancer controls. We conducted a retrospective, cross-sectional, matched case-control study using data from Korean National Health and Nutrition Examination Surveys (KNHANES) VI-VII (2013-2018) to compare health-promoting behaviors. We selected breast cancer survivors aged 40 to 65 who completed the surveys, and each case was matched with 5 non-cancer controls (1:5) based on propensity scores. With multivariable logistic regression, middle-aged breast cancer survivors were compared with controls in terms of their last screening for a second primary cancer (SPC), current smoking status, alcohol consumption, aerobic physical activity (PA), sedentary time, and self-reported diet control. The final study sample consisted of 117 middle-aged breast cancer survivors and 585 non-cancer controls after propensity score matching (PSM). In the multivariable analysis, middle-aged breast cancer survivors were less likely to consume alcohol (odds ratio [OR] 0.58, 95% confidence interval [CI], 0.35-0.95), more likely to engage in aerobic PA (OR, 1.60; 95% CI, 1.01-2.54), and more likely to self-report diet control (OR, 2.12; 95% CI, 1.27-3.53). There were no significant intergroup differences in SPC screening uptake within 2 years, smoking status, or sedentary times. There is a need to educate middle-aged breast cancer survivors about SPC screening, smoking cessation, and minimizing sedentariness to reduce the risks of associated with breast cancer recurrence, SPCs, and comorbid chronic diseases.Copyright © 2023 the Author(s).
