摘　　要：Background Physical activity(PA)and reductions in sedentary behavior(SED)may mitigate cancer-related cognitive impairment.The purpose of this study was to examine(a)the associations between changes in PA,SED,and cognitive function in cancer survivors before and during the coronavirus disease 2019(COVID-19)pandemic;and(b)clinical subgroups that moderate this association.Methods A cross-sectional survey was administered online to adult cancer survivors globally between July and November of 2020.This was a secondary analysis of a cross-sectional survey examining changes in self-reported PA and quality of life in cancer survivors before and during the COVID-19 pandemic.Self-reported Questionnaires assessed moderate-to-vigorous PA(MVPA)using the modified Godin Leisure Time Exercise Questionnaire,cognitive function using the Functional Assessment of Cancer Therapy-Cognitive Function(FACT-Cog)scale,and SED using the Domain-specific Sitting Time questionnaire.Cancer survivors were classified into no change in behavior,desirable change(i.e.,increase MVPA to meet PA guidelines or decrease SED by≥60 min/day),and undesirable change(i.e.,decrease MVPA to<150 min/week or increase SED by≥60 min/day).Analysis of covariance examined differences in FACT-Cog scores across the activity change categories.Planned contrasts compared differences in FACT-Cog scores between cancer survivors with(a)no meaningful change vs.any change,and(b)a desirable change vs.an undesirable change.Results There were no significant differences in FACT-Cog scores across activity-change categories in the full sample of cancer survivors(n=371;age=48.6±15.3 years(mean±SD)).However,cancer survivors who were diagnosed≥5 years ago(t(160)=–2.15,p=0.03)or who received treatment≥5 years ago(t(102)=–2.23,p=0.03)and who had a desirable change in activity reported better perceived cognitive abilities than those who had an undesirable change.Conclusion PA promotion efforts should consider reducing SED in addition to maintaining MVPA in long-term cancer sur
