RESUMO

OBJECTIVE: To compare prevalence of e-cigarette and cigarette use and to determine predictors of dual use. DESIGN, SETTING, AND PARTICIPANTS: Using a countywide random digit dial telephone health survey conducted during January 2018 to March 2019, we analyzed data from a random sample of 6966 adults. Bivariate analyses described vaping, cigarette use, and sociodemographics. A multivariable logistic regression model examined dual use. RESULTS: Young adults 18 to 24 years of age had the highest prevalence of e-cigarette-only use (11.5%), the second-highest prevalence of dual use (3.9%), and the lowest prevalence of cigarette-only use (5.8%). Males were more likely than females to use e-cigarettes (5.1% vs 2.7%), traditional cigarettes (11.1% vs 6.9%), or be dual users (3.6% vs 1.1%). Of those who used e-cigarettes or both, approximately half had also used marijuana in the past 30 days. CONCLUSIONS: E-cigarette use among young adults is concerning because it could lead to eventual dual use of e-cigarettes and traditional cigarettes.

RESUMO

BACKGROUND: The prevalence of current or past coronavirus disease 2019 in skilled nursing facility (SNF) residents is unknown because of asymptomatic infection and constrained testing capacity early in the pandemic. We conducted a seroprevalence survey to determine a more comprehensive prevalence of past coronavirus disease 2019 in Los Angeles County SNF residents and staff members. METHODS: We recruited participants from 24 facilities; participants were requested to submit a nasopharyngeal swab sample for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) testing and a serum sample for detection of SARS-CoV-2 antibodies. All participants were cross-referenced with our surveillance database to identify persons with prior positive SARS-CoV-2 results. RESULTS: From 18 August to 24 September 2020, we enrolled 3305 participants (1340 residents and 1965 staff members). Among 856 residents providing serum samples, 362 (42%) had current or past SARS-CoV-2 infection. Of the 346 serology-positive residents, 199 (58%) did not have a documented prior positive SARS-CoV-2 PCR result. Among 1806 staff members providing serum, 454 (25%) had current or past SARS-CoV-2 infection. Of the 447 serology-positive staff members, 353 (79%) did not have a documented prior positive SARS-CoV-2 PCR result. CONCLUSIONS: Past testing practices and policies missed a substantial number of SARS-CoV-2 infections in SNF residents and staff members.
