Closure of Anchor Businesses Reduced COVID-19 Transmission During the Early Months of the Pandemic.
Ontology highlight
ABSTRACT: Objectives
To investigate the relationship between the closure of "anchor businesses" - manufacturing plants and distribution centers employing >1000 workers - and the daily, county-level COVID-19 rate between March 1, 2020 and May 31, 2020.Methods
We conducted a comparative, interrupted time series analysis of publicly available county-level data. Our main variable of interest was closure, indicating whether one or more of the anchor businesses within the county experienced a full or partial closure of at least 22 days (main analysis) or at least 1 day (sensitivity analyses).Results
Closure of an anchor business was associated with 142 fewer positive COVID-19 tests per 100,000 population over a 40-day period. Even short-term and partial closures were associated with reduced spread.Conclusions
Temporary closure of anchor businesses appears to have slowed, but not completely contained, the spread of COVID-19.

Project description:The true risk of a COVID-19 resurgence as states reopen businesses is unknown. In this paper, we used anonymized cell-phone data to quantify the potential risk of COVID-19 transmission in business establishments by building a Business Risk Index that measures transmission risk over time. The index was built using two metrics, visits per square foot and the average duration of visits, to account for both density of visits and length of time visitors linger in the business. We analyzed trends in traffic patterns to 1,272,260 businesses across eight states from January 2020 to June 2020. We found that potentially risky traffic behaviors at businesses decreased by 30% by April. Since the end of April, the risk index has been increasing as states reopen. There are some notable differences in trends across states and industries. Finally, we showed that the time series of the average Business Risk Index is useful for forecasting future COVID-19 cases at the county-level (P < 0.001). We found that an increase in a county's average Business Risk Index is associated with an increase in positive COVID-19 cases in 1 week (IRR: 1.16, 95% CI: (1.1-1.26)). Our risk index provides a way for policymakers and hospital decision-makers to monitor the potential risk of COVID-19 transmission from businesses based on the frequency and density of visits to businesses. This can serve as an important metric as states monitor and evaluate their reopening strategies.

Project description:BackgroundThe COVID-19 pandemic has precipitated an unpredictable economic crisis, currently affecting daily life for millions of workers. We examined the mental health impact of reduced working in a nationally representative sample of employees.MethodWe used Wave one (April 2020) of the Understanding Society UK Household Longitudinal Study (UKHLS) COVID-19 study, with linkage to baseline mental health data from the UKHLS annual survey (January 2017- December 2018). Analysis was based on adults aged 18-65 who were employees in January/February 2020 (n=8,708), with psychological distress assessed using the GHQ-12. Logistic regression examined the mental health impact of reduced working and reasons for the reduction.ResultsForty two percent of employees reported reduced working by April 2020, with 22% furloughed. There was no evidence of an association between reduced working per se and psychological distress in the fully adjusted model (OR=1.06, 95%CI 0.91-1.23). Those permanently laid-off (less than 1% of employees) were most vulnerable to adverse mental health effects in the early months of the pandemic (OR=3.60, 95%CI 1.55-8.37). We also found evidence of higher levels of psychological distress among those sick or self-isolating, and those with reduced working due to caring responsibilities.LimitationsWhile the GHQ is a widely used and validated instrument in identifying potential psychiatric disorders, it is important to note that it does not represent a clinical assessment.ConclusionsLongitudinal examination of employment transitions and mental ill-health related to pandemic outcomes is imperative and should help inform public health responses and ongoing government policy in supporting those adversely affected.

Project description:ObjectiveAs impacts of the COVID-19 pandemic continue to unfold, research is needed to understand how school-aged youth are coping with COVID-19-related changes and disruptions to daily life. Among a sample of Canadian youth, our objective was to examine the mental health factors associated with using substances to cope with COVID-19-related changes, taking account of expected sex differences.MethodsWe used online data collected from 7150 students in the COMPASS study, during the early months of the COVID-19 pandemic (May-July 2020) in British Columbia, Ontario, and Quebec, Canada. We specified a sex-stratified, generalized linear mixed model to estimate the likelihood of engagement in substance-related coping behaviours, while testing for the effects of students' mental health, individual characteristics, and school neighborhood characteristics.ResultsTwelve percent of students (13.4% of females, 9.9% of males) in our sample reported using cannabis, alcohol, cigarettes, and/or vaping to help cope with COVID-19-related changes. Regardless of sex, students with greater depressive symptoms were more likely to engage in substance-related coping (aORFemale = 1.04, 95 %CI[1.01-1.07]; aORMale = 1.06, 95 %CI[1.013-1.11]). Among females, better psychosocial wellbeing was protective against engagement in substance related-coping (aOR = 0.96, 95 %CI[0.94-0.98]), controlling for current substance use.ConclusionsCanadian school-aged youth with generally poor mental health may be more likely to have engaged in substance use to help cope with COVID-19-related changes during the first wave of the pandemic, and female youth may be at disproportionate risk of engaging in the behaviour. Ongoing evaluation of the impacts of COVID-19 on youth health is required.

Project description:ObjectiveHospice aides are vital in delivering care to patients and family members at the end of life. The COVID-19 pandemic resulted in disruptions in hospice care delivery, especially in long-term care settings. We aim to provide a description of hospice aide visits among nursing home residents enrolled in hospice during the first 9 months of 2020, as compared with the same months in 2019.DesignObservational cohort study.Setting and participants153,109 and 152,077 long-stay nursing home residents enrolled in hospice in 2019 and 2020, respectively.MethodsOn a monthly basis, we reported estimated probabilities of not having visits from hospice aides and adjusted visit minutes among those who had hospice aide visits for the 2019 and 2020 cohort, respectively. The regression models accounted for resident sociodemographic and clinical characteristics and nursing home fixed effects. The analyses were conducted at the national and state level, separately.ResultsMore than half of residents did not have any visits from hospice aides in 2020 from April and onward. Among residents who had hospice aide visits, the 2020 cohort had reduced visits in March and onward, with the greatest difference being 155 minutes less in April (95% CI: -163.4, -146.5). State-level analyses suggested that multiple factors besides community spread or state policies might contribute to the reduced presence of hospice aides.Conclusions and implicationsOur findings highlight the toll of the pandemic on hospice care delivery in nursing homes and the need for hospice care to be better incorporated into emergency preparedness planning.

Project description:It is not known how school closure affected child maltreatment. We conducted a retrospective cohort, linear mixed-models study of 133 counties (comprising 8,582,479 children) in Virginia between 2018 and 2021. Exposure was the opening of schools at least 2 days a week. Outcomes were referrals and incidence of child maltreatment reported to the Department of Social Services. In 2020-2021, there were descriptively more referrals (in-person: 50.9 per 10,000 [95% CI: 47.9, 54.0]; virtual: 45.8 per 10,000 [95% CI: 40.7, 50.9]) and incidence (in-person: 3.7 per 10,000 [95% CI: 3.3, 4.2]; virtual: 2.9 per 10,000 [95% CI: 2.3, 3.5]) of child maltreatment in counties with in-person schooling, though these differences did not reach statistical significance. The referral rate variations (between pandemic and pre-pandemic eras) of counties with in-person schooling was significantly greater than rate changes in counties with virtual schooling during the summer period. There were no differences in incidence in any quarter. Higher poverty within a county was associated with both higher referrals and incidence. Our findings suggest that child maltreatment is driven primarily by underlying differences in counties (namely, poverty) rather than the type of schooling children receive.
