    Abstract:
    BACKGROUND: Secondhand smoke (SHS) poses a significant public health threat. Cancer survivors are at a greater risk of adverse health outcomes from SHS because of its association with poor prognosis and other downstream clinical events. METHODS: A nationally representative sample of US adults aged 20 years and older was analyzed from the National Health and Nutrition Examination Survey between 2013 and 2020. Data on indoor SHS exposure were reported by 16,778 adults who were not currently smoking (1775 cancer survivors; 15,003 individuals without a cancer history). The weighted prevalence of SHS exposure was estimated and compared across sociodemographic and health-related characteristics. Multivariable logistic regression models were fitted to identify correlates of SHS exposure. RESULTS: Of the 1775 nonsmoking cancer survivors (mean age, 64.9 years; 57.0% female; 84.4% non-Hispanic Whites), 15.8% reported SHS exposure. No significant change in trends of SHS exposure was observed during the study period. The prevalence of SHS exposure was higher in cancer survivors who were younger, racial minorities, and had a household income below 130% of the federal poverty level. After adjustment for multiple correlates, age below 40 years, low income, smoking history, and diagnosis within 2 years were associated with SHS exposure. Cancer survivors were most likely to report that SHS exposure occurred at home or in a car. CONCLUSIONS: The prevalence of SHS exposure among cancer survivors remained steady in the past decade. However, disparities exist in SHS exposure among cancer survivors across sociodemographic characteristics and smoking status. Smoking cessation programs should be promoted among caregivers and families of cancer survivors.
