Objective:　To　explore　the　impact　of　COVID-19　on　the　sleep　of　healthcare　workers　from　Fujian　Province　supporting　Hubei　Province　and　its　related　risk　factors.　Methods:　A　cross-sectional,　anonymous,　self-reported　online　questionnaire　survey　was　conducted　among　all　participants.　The　questionnaire　consisted　of　five　parts:　sociodemographic　characteristics　and　COVID-19　epidemic-related　factors,　Pittsburgh　Sleep　Quality　Index　(PSQI),　Epworth　Sleepiness　Scale　(ESS),　Morningness-Eveningness　Questionnaire-5　(MEQ-5),　and　12-item　General　Health　Questionnaire　(GHQ-12).　Results:　Among　552　participants,　203　(36.8%)　had　a　PSQI　score　＞　7,　indicating　the　presence　of　sleep　disorders.　Logistic　regression　analysis　revealed　that　sleep　disorders　were　independently　associated　with　a　history　of　previously　diagnosed　sleep　disorders　(OR　6.074,　95%　CI　2.626-14.049,　P　＜　0.001),　rotating　night　shifts　＞　3　times　per　week　(OR　3.089,　95%　CI　1.650-5.781,　P　＜　0.001),　using　electronic　devices　before　sleep　＞1　h　(OR　1.685,　95%　CI　1.131-2.511,　P　=　0.010),　concern　about　contracting　COVID-19　(OR　1.116,　95%　CI　1.034-1.204,　P　=　0.005),　perception　of　societal　support　for　supporting　healthcare　workers　in　Hubei　(OR　0.861,95%　CI　0.744-0.998,　P　=　0.047)　(OR　0.861,　95%　CI　0.744-0.998,　P　=　0.047),　non-medical　staff　(OR　0.257,　95%　CI　0.067-0.987,　P　=　0.048),　ESS　score　(OR　1.068,　95%　CI　1.018-1.121,　P　=　0.007),　and　GHQ-12　score　(OR　1.511,　95%　CI　1.281-1.782,　P　＜　0.001).　Conclusion:　Sleep　disorders　were　highly　prevalent　among　healthcare　workers　from　Fujian　Province　supporting　Hubei　Province　during　the　COVID-19　pandemic.　Risk　factors　for　sleep　disorders　included　a　history　of　previously　diagnosed　sleep　disorders,　rotating　night　shifts　＞　3　times　per　week,　using　electronic　devices　before　sleep　＞1　h,　excessive　concern　about　contracting　COVID-19,　and　poorer　psychological　health.　Higher　perceived　societal　support　and　understanding　of　support　for　healthcare　workers　supporting　Hubei　were　associated　with　a　reduced　risk　of　sleep　disorders,　as　was　being　non-medical　staff.　Providing　more　sleep　hygiene　education　and　psychological　health　services　for　frontline　healthcare　workers　is　necessary.
