Prior studies investigating the relationship between sleep and serious psychological distress (SPD) have lacked racial/ethnic diversity and generalizability. We investigated associations between sleep and SPD among a large, nationally representative, and racially/ ethnically diverse sample of US adults. Methods: We pooled cross-sectional data from the 2004 to 2017 National Health Interview Survey. Participants self-reported sleep duration and sleep disturbances (eg, trouble falling and staying asleep). SPD was defined as a Kessler Psychological Distress Scale (K6) score ≥13. Adjusting for sociodemographic, health behavior, and clinical characteristics, we used Poisson regression with robust variance to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) of SPD for each sleep characteristic, overall and by race/ethnicity. Results: Among 316,840 participants, the mean age ± standard error was 46.9 ± 0.1 years, 52% were women, 75% were non-Hispanic (NH)-White, 16% NH-Black, and 9% Hispanic/ Latinx. The prevalence of SPD was 3.4% for NH-Whites, 4.1% for NH-Blacks, and 4.5% for Hispanics/Latinxs. Participants with <7 hours versus 7-9 hours of sleep duration were more likely to have SPD, and the magnitude of the association was strongest among NH-Black participants (PR NH-Blacks =3.50 [95% CI: 2.97-4.13], PR Hispanics/Latinx =2.95 [2.42-3.61], and PR NH-Whites =2.66 [2.44-2.89]). Positive associations between sleep disturbances and SPD were generally stronger among NH-Black and Hispanic/Latinx compared to NH-White adults. Conclusion: Poor sleep health was positively associated with SPD, and the magnitude of the association was generally stronger among racial/ethnic minorities. Future investigations should prospectively focus on the determinants and health consequences of SPD attributable to objectively measured sleep across racial/ethnic groups.
Background
Robust community-level SARS-CoV-2 prevalence estimates have been difficult to obtain in the American South and outside of major metropolitan areas. Furthermore, though some previous studies have investigated the association of demographic factors such as race with SARS-CoV-2 exposure risk, fewer have correlated exposure risk to surrogates for socioeconomic status such as health insurance coverage.
Methods
We used a highly specific serological assay utilizing the receptor binding domain of the SARS-CoV-2 spike-protein to identify SARS-CoV-2 antibodies in remnant blood samples collected by the University of North Carolina Health system. We estimated the prevalence of SARS-CoV-2 in this cohort with Bayesian regression, as well as the association of critical demographic factors with higher prevalence odds.
Findings
Between April 21st and October 3rd of 2020, a total of 9,624 unique samples were collected from clinical sites in central NC and we observed a seroprevalence increase from 2.9 (1.7, 4.3) to 9.1 (7.2, 11.1) over the study period. Individuals who identified as Latinx were associated with the highest odds ratio of SARS-CoV-2 exposure at 7.77 overall (5.20, 12.10). Increased odds were also observed among Black individuals and individuals without public or private health insurance.
Interpretation
Our data suggests that for this care-accessing cohort, SARS-CoV-2 seroprevalence was significantly higher than cumulative total cases reported for the study geographical area six months into the COVID-19 pandemic in North Carolina. The increased odds of seropositivity by ethnoracial grouping as well as health insurance highlights the urgent and ongoing need to address underlying health and social disparities in these populations.
PCR-confirmed SARS-CoV-2 cases underestimate true prevalence. Few robust community-level SARS-CoV-2 ethnoracial and overall prevalence estimates have been published for North Carolina in 2020.
Technological advances over 12 years in endovascular stroke treatments significantly improved the chance of and reduced time to achieving TICI 2b recanalization in our community hospital. This shows the importance of adopting new technologies in a rapidly evolving field in order to provide the best-practice standard of care for the people of our region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
