{"doi":"10.1017/ash.2024.485","title":"Association between social activities and risk of COVID-19 in a cohort of healthcare personnel","abstract":"Objective: Previous studies have linked social behaviors to COVID-19 risk in the general population. The impact of these behaviors among healthcare personnel, who face higher workplace exposure risks and possess greater prevention awareness, remains less explored. Design: We conducted a Prospective cohort study from December 2021 to May 2022, using monthly surveys. Exposures included (1) a composite of nine common social activities in the past month and (2) similarity of social behavior compared to pre-pandemic. Outcomes included self-reported SARS-CoV-2 infection (primary)and testing for SARS-CoV-2 (secondary). Mixed-effect logistic regression assessed the association between social behavior and outcomes, adjusting for baseline and time-dependent covariates. To account for missed surveys, we employed inverse probability-of-censoring weighting with a propensity score approach. Setting: An academic healthcare system. Participants: Healthcare personnel. Results: Of 1,302 healthcare personnel who completed ≥2 surveys, 244 reported ≥1 positive test during the study, resulting in a cumulative incidence of 19%. More social activities in the past month and social behavior similar to pre-pandemic levels were associated with increased likelihood of SARS-CoV-2 infection (recent social activity composite: OR = 1.11, 95% CI 1.02-1.21; pre-pandemic social similarity: OR = 1.14, 95% CI 1.07-1.21). Neither was significantly associated with testing for SARS-CoV-2. Conclusions: Healthcare personnel social behavior outside work was associated with a higher risk for COVID-19. To protect the hospital workforce, risk mitigation strategies for healthcare personnel should focus on both the community and workplace.","journal":"Antimicrobial Stewardship & Healthcare Epidemiology","year":2025,"id":542941,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.7183,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":734005,"name":"Haojia Li","orcid":"0000-0002-1295-4341","position":1,"is_corresponding":false},{"id":424143,"name":"Yue Zhang","orcid":"0000-0002-4124-4816","position":2,"is_corresponding":false},{"id":475169,"name":"Jeanmarie Mayer","orcid":"0000-0002-7699-4414","position":3,"is_corresponding":false},{"id":369285,"name":"Michael Rubin","orcid":"0000-0002-3177-133X","position":4,"is_corresponding":false},{"id":518380,"name":"Candace Haroldsen","orcid":null,"position":5,"is_corresponding":false},{"id":383867,"name":"Morgan M.
