Symptoms were evaluated using single\u2010item measures (PRSM, PRO\u2010CTCAE) at repeated timepoints. Generalized estimating equation methods estimated the odds of experiencing depressive or anxiety symptoms according to baseline smoking, alcohol use, and physical activity, adjusting for age, race, living alone, and chemotherapy regimen.

At least moderately severe depressive and anxiety symptoms were reported by 27% and 38%, respectively, and were most prevalent during the first 3\u00a0weeks of chemotherapy. Participants who reported current smoking had higher odds of depressive symptoms compared to those who never smoked (aOR 3.17, 95% CI 1.27\u20137.96) and higher odds of anxiety symptoms compared to both participants who never (aOR 3.67, 95% CI 1.70\u20137.95) and previously smoked (aOR 3.03, 95% CI 1.5\u20136.79).
