Changes in anxiety and depression among public health workers during the COVID-19 pandemic response.

OBJECTIVES: The COVID-19 pandemic has negatively impacted mental health indicators, leading to an increase in symptoms of anxiety and depression in both the general population of adults and children and many occupational groups. This study aims to examine changes in anxiety and depression among a cohort of public health workers in the U.S. during the first year of the COVID-19 pandemic and identify potential risk factors. METHODS: Longitudinal data were collected from a sub-sample (N = 85) of public health workers in 23 U.S. states who completed two surveys in 2020 and 2021. Information on background characteristics, personal well-being, and work environment as well as validated scales to assess generalized anxiety disorder (GAD), depressive disorder, and burnout was collected. Data were analyzed using Stata Version 17, and significant differences were determined using Pearson's Chi2 and Fisher's Exact tests. RESULTS: The proportion of those reporting GAD (46.3% to 23.2%) or depression (37.8% to 26.8%) improved from Survey 1 to Survey 2 overall; symptoms of anxiety saw the largest improvement. Persistent depression was associated with sustained burnout, changes in social support, and days worked per week. CONCLUSION: Public health workers experienced elevated levels of anxiety and depression during the initial pandemic response, but a reduction in these symptoms was observed in the subsequent year after vaccines had become widely available. However, unmet needs remain for ongoing workplace mental health supports to address burnout, as well as for additional emotional supports outside of work for public health professionals.

Occupational heat exposure among municipal workers.

PURPOSE: Outdoor workers face elevated and prolonged heat exposures and have limited access to air-conditioned spaces. This study's overarching research aim is to increase knowledge of municipal worker heat exposure and adaptation practices. The study's sub-objectives are: (1) quantifying exposure misclassification from estimating personal heat exposure from the official weather station; (2) surveying worker's knowledge and practices to adapt to extreme heat; and (3) relating heat exposure and adaptation practices to self-reported thermal comfort. METHODS: Participants wore a personal heat exposure sensor over 7 days from June 1st to July 3rd, 2015 in Tallahassee, Florida US. Next, participants confirmed the days that they wore the sensor and reported their daily thermal comfort and heat adaptations. Finally, participants completed an extreme heat knowledge, attitudes, and practices survey. RESULTS: Some participants (37%) experienced hotter and more humid conditions (heat index > 2) than the weather station. The most common heat adaptations were staying hydrated (85%), wearing a hat (46%), and seeking shade (40%). During work hours, higher temperatures increased the odds (odds ratio: 1.21, 95% confidence interval: 1.03-1.41, p = 0.016) of a participant feeling too hot. Shifting work duty indoors made workers to feel more comfortable (odds ratio: 0.28, 95% confidence interval: 0.11-0.70, p = 0.005). CONCLUSION: In hot and humid climates, everyday, heat exposures continuously challenge the health of outdoor workers.

Adverse Health Outcomes Following Hurricane Harvey: A Comparison of Remotely-Sensed and Self-Reported Flood Exposure Estimates.

Remotely sensed inundation may help to rapidly identify areas in need of aid during and following floods. Here we evaluate the utility of daily remotely sensed flood inundation measures and estimate their congruence with self-reported home flooding and health outcomes collected via the Texas Flood Registry (TFR) following Hurricane Harvey. Daily flood inundation for 14 days following the landfall of Hurricane Harvey was acquired from FloodScan. Flood exposure, including number of days flooded and flood depth was assigned to geocoded home addresses of TFR respondents (N = 18,920 from 47 counties). Discordance between remotely-sensed flooding and self-reported home flooding was measured. Modified Poisson regression models were implemented to estimate risk ratios (RRs) for adverse health outcomes following flood exposure, controlling for potential individual level confounders. Respondents whose home was in a flooded area based on remotely-sensed data were more likely to report injury (RR = 1.5, 95% CI: 1.27-1.77), concentration problems (1.36, 95% CI: 1.25-1.49), skin rash (1.31, 95% CI: 1.15-1.48), illness (1.29, 95% CI: 1.17-1.43), headaches (1.09, 95% CI: 1.03-1.16), and runny nose (1.07, 95% CI: 1.03-1.11) compared to respondents whose home was not flooded. Effect sizes were larger when exposure was estimated using respondent-reported home flooding. Near-real time remote sensing-based flood products may help to prioritize areas in need of assistance when on the ground measures are not accessible.

Threats to public health workers.

Media reports and data from public health professional membership organizations have demonstrated high levels of harassment experienced by public health workers throughout the COVID-19 response. We documented personal and political threats to public health workers across the first 12 months of pandemic response through a longitudinal survey completed in Fall 2020 and Summer 2021. The web-based survey was distributed to respondents using the Qualtrics survey platform. Survey items measured domains including demographic information, public health roles and training, mental and physical health, and work-life balance. Respondents were also asked if they had received any personal or political threats, from whom these threats were received, and completed an open-ended question describing the nature of the threats. Among the 85 public health workers completing both surveys, threats from members of the public and from elected and appointed leaders were most prevalent at both timepoints; however, as the pandemic response progressed, the nature of threats to public health workers changed. While those remaining in the public health workforce may be more resilient to these threats, increased prevalence of personal and political threats has the potential to deter new graduates from entering the field, impacting the public health system's future response capacity.

Estimating changes in emergency department visits associated with floods caused by Tropical Storm Imelda using satellite observations and syndromic surveillance.

BACKGROUND: Satellite observations following flooding coupled with electronic health data collected through syndromic surveillance systems (SyS) may be useful in efficiently characterizing and responding to health risks associated with flooding. RESULTS: There was a 10% (95% Confidence Interval (CI): 1%-19%) increase in asthma related ED visits and 22% (95% CI: 5%-41%) increase in insect bite related ED visits in the flooded ZCTAs compared to non-flooded ZCTAs during the flood period. One month following the floods, diarrhea related ED visits were increased by 15% (95% CI: 4%-27%) for flooded ZCTAs and children and adolescents from flooded ZCTAs had elevated risk for dehydration related ED visits. During the protracted period (2-3 months after the flood period), the risk for asthma, insect bite, and diarrhea related ED visits were elevated among the flooded ZCTAs. Effect modification by reported age, ethnicity and race was observed. CONCLUSION: Combining satellite observations with SyS data can be helpful in characterizing the location and timing of environmentally mediated adverse health outcomes, which may be useful for refining disaster resilience measures to mitigate health outcomes following flooding.

Lessons Learned From the Public Health Workforce's Experiences With the COVID-19 Response.

Limited research is available on the COVID-19 response experiences of local, state, and federal public health workers in the United States. Although the response to COVID-19 is still presenting challenges to the public health workforce, public health systems must also begin to consider lessons learned that can be applied to future disasters. During July and August 2021, a random sample of participants from a cross-sectional study of the public health workforce was invited to participate in interviews to obtain information on the current state of public health operations, the ongoing response to the COVID-19 crisis, and takeaways for improving future preparedness and response planning. Interviews were transcribed and inductively coded to identify themes. Twenty-four initial interview invitations were sent, and random substitutions were made until thematic saturation was reached when 17 interviews were completed. Four thematic categories were identified, including challenges related to (1) ongoing lack of political support or policy guidance; (2) fluctuations in, and uncertainty about, future funding and associated requirements; (3) job expectations, including remote work and data-sharing capabilities; and (4) the mental health toll of sustained response and related burnout. As the public health response to the COVID-19 pandemic continues in its third year, it is crucial to identify lessons learned that can inform future investment in order to sustain a public health workforce and a public health preparedness and response system that is resilient to future disasters.

The impact of the COVID-19 response on the provision of other public health services in the U.S.: A cross sectional study.

INTRODUCTION: Funding and staff formerly dedicated to routine public health tasks (e.g., responding to communicable and non-communicable diseases, investigating foodborne outbreaks, conducting routine surveillance) and services (e.g., environmental health, substance abuse, maternal-child health) may no longer be available in many public health departments due to the COVID-19 response. The objective of this study was to assess the extent to which staffing for essential public health services has been redirected to the COVID-19 response. MATERIALS AND METHODS: This is a cross-sectional study using a survey distributed through the Qualtrics platform. Individuals (N = 298) working in public health across governmental and academic public health departments in the U.S. during the ongoing COVID-19 pandemic response were surveyed. Survey items measured multiple domains including professional experience (i.e., training, years of experience, content expertise, job functions, hours worked), mental and physical health status (i.e., generalized anxiety, depression, burnout), and career plans (i.e., pre-pandemic vs. current career plans). RESULTS: The total number of content expertise areas and programmatic functions covered by individual public health workers increased between January and September of 2020, with 26% (73 of 282) of respondents reporting an increase in both. The total number of respondents working in infectious disease and preparedness remained constant, while declines were reported in program evaluation (-36%) and health education (-27%) and increases were reported in disease investigation (+35%). CONCLUSIONS: The provision of many essential public health functions and tasks have been limited or eliminated while the U.S. public health workforce responds to the COVID-19 pandemic. These findings highlight opportunities for funding and professional development of public health systems, both during and after the COVID-19 response, to help ensure the continuity of essential public health services, staffing sustainability, and preparedness for future public health emergencies in the U.S.

Public Health Workforce Burnout in the COVID-19 Response in the U.S.

While the health impacts of the COVID-19 pandemic on frontline health care workers have been well described, the effects of the COVID-19 response on the U.S. public health workforce, which has been impacted by the prolonged public health response to the pandemic, has not been adequately characterized. A cross-sectional survey of public health professionals was conducted to assess mental and physical health, risk and protective factors for burnout, and short- and long-term career decisions during the pandemic response. The survey was completed online using the Qualtrics survey platform. Descriptive statistics and prevalence ratios (95% confidence intervals) were calculated. Among responses received from 23 August and 11 September 2020, 66.2% of public health workers reported burnout. Those with more work experience (1-4 vs. <1 years: prevalence ratio (PR) = 1.90, 95% confidence interval (CI) = 1.08-3.36; 5-9 vs. <1 years: PR = 1.89, CI = 1.07-3.34) or working in academic settings (vs. practice: PR = 1.31, CI = 1.08-1.58) were most likely to report burnout. As of September 2020, 23.6% fewer respondents planned to remain in the U.S. public health workforce for three or more years compared to their retrospectively reported January 2020 plans. A large-scale public health emergency response places unsustainable burdens on an already underfunded and understaffed public health workforce. Pandemic-related burnout threatens the U.S. public health workforce's future when many challenges related to the ongoing COVID-19 response remain unaddressed.

A Qualitative Study of the COVID-19 Response Experiences of Public Health Workers in the United States.

The mental health impacts of the COVID-19 pandemic on frontline, patient-facing healthcare staff have been described in several studies, but the effects of the COVID-19 response on the US public health workforce have not been well characterized. In early 2021, we conducted interviews with a subset of public health practitioners in the United States who participated in a cross-sectional survey and indicated their willingness to participate in a follow-up interview. An interview guide was developed to collect information about professional roles since the start of the pandemic, aspects of the individual COVID-19 response that impacted mental health, and aspects of the organizational/institutional COVID-19 response that impacted mental health, as well as the strengths and weaknesses of, opportunities for, and threats to public health professionals and organizations going forward. Interviews were transcribed and inductively coded to identify themes. Of the 48 people invited to participate, 24 completed an interview between January 28 and February 23, 2021. Five key themes were identified through inductive coding of interview transcripts: (1) teamwork and workplace camaraderie, (2) potential for growth in the field of public health, (3) considerations for adaptive work environments (eg, remote work, work out of jurisdiction, transition to telework), (4) politicization of response, and (5) constrained hiring capacity and burnout. After more than a year of public health emergency response to the COVID-19 pandemic, it is critically important to understand the detrimental and supportive factors of good mental health among the public health workforce.

Emergency department visits associated with satellite observed flooding during and following Hurricane Harvey.

BACKGROUND: Flooding following heavy rains precipitated by hurricanes has been shown to impact the health of people. Earth observations can be used to identify inundation extents for subsequent analysis of health risks associated with flooding at a fine spatio-temporal scale. OBJECTIVE: To evaluate emergency department (ED) visits before, during, and following flooding caused by Hurricane Harvey in 2017 in Texas. METHODS: A controlled before and after design was employed using 2016-2018 ED visits from flooded and non-flooded census tracts. ED visits between landfall of the hurricane and receding of flood waters were considered within the flood period and post-flood periods extending up to 4 months were also evaluated. Modified Poisson regression models were used to estimate adjusted rate ratios for total and cause specific ED visits. RESULTS: Flooding was associated with increased ED visits for carbon monoxide poisoning, insect bite, dehydration, hypothermia, intestinal infectious diseases, and pregnancy complications. During the month following the flood period, the risk for pregnancy complications and insect bite was still elevated in the flooded tracts. SIGNIFICANCE: Earth observations coupled with ED visits increase our understanding of the short-term health risks during and following flooding, which can be used to inform preparedness measures to mitigate adverse health outcomes and identify localities with increased health risks during and following flooding events.

Heavy precipitation as a risk factor for shigellosis among homeless persons during an outbreak - Oregon, 2015-2016.

OBJECTIVES: Shigella species are the third most common cause of bacterial gastroenteritis in the United States. During a Shigella sonnei outbreak in Oregon from July 2015 through June 2016, Shigella cases spread among homeless persons with onset of the wettest rainy season on record. METHODS: We conducted time series analyses using Poisson regression to determine if a temporal association between precipitation and shigellosis incidence existed. Models were stratified by housing status. RESULTS: Among 105 infections identified, 45 (43%) occurred in homeless persons. With increasing precipitation, cases increased among homeless persons (relative risk [RR] = 1.36 per inch of precipitation during the exposure period; 95% confidence interval [CI] = 1.17-1.59), but not among housed persons (RR = 1.04; 95% CI 0.86-1.25). CONCLUSIONS: Heavy precipitation likely contributed to shigellosis transmission among homeless persons during this outbreak. When heavy precipitation is forecast, organizations working with homeless persons could consider taking proactive measures to mitigate spread of enteric infections.

Opportunities and Challenges for Personal Heat Exposure Research.

BACKGROUND: Environmental heat exposure is a public health concern. The impacts of environmental heat on mortality and morbidity at the population scale are well documented, but little is known about specific exposures that individuals experience. OBJECTIVES: The first objective of this work was to catalyze discussion of the role of personal heat exposure information in research and risk assessment. The second objective was to provide guidance regarding the operationalization of personal heat exposure research methods. DISCUSSION: We define personal heat exposure as realized contact between a person and an indoor or outdoor environment that poses a risk of increases in body core temperature and/or perceived discomfort. Personal heat exposure can be measured directly with wearable monitors or estimated indirectly through the combination of time-activity and meteorological data sets. Complementary information to understand individual-scale drivers of behavior, susceptibility, and health and comfort outcomes can be collected from additional monitors, surveys, interviews, ethnographic approaches, and additional social and health data sets. Personal exposure research can help reveal the extent of exposure misclassification that occurs when individual exposure to heat is estimated using ambient temperature measured at fixed sites and can provide insights for epidemiological risk assessment concerning extreme heat. CONCLUSIONS: Personal heat exposure research provides more valid and precise insights into how often people encounter heat conditions and when, where, to whom, and why these encounters occur. Published literature on personal heat exposure is limited to date, but existing studies point to opportunities to inform public health practice regarding extreme heat, particularly where fine-scale precision is needed to reduce health consequences of heat exposure. https://doi.org/10.1289/EHP556.

Prevalence of and beliefs about electronic cigarettes and hookah among high school students with asthma.

PURPOSE: To assess current cigarette, hookah, and electronic cigarette (e-cigarette) use among high school students with and without asthma. Beliefs and use of tobacco products by a household member were also examined. METHODS: The 2014 Florida Youth Tobacco Survey was administered to high school students to assess current use of cigarettes, hookah, and e-cigarettes (i.e., within past 30 days). Student's home exposure and beliefs about cigarettes, hookah, and e-cigarettes were also assessed. Students were randomly selected using a two-stage cluster probability design. RESULTS: Adolescents with asthma had a higher prevalence of current hookah (14.0%) and e-cigarette use (12.4%) compared with their peers (10.9%, 10.2%, respectively). Adolescents with asthma were also at increased risk for current use of cigarettes (adjusted odds ratio [AOR]: 1.24), hookah (AOR: 1.32), and e-cigarettes (AOR: 1.34). Adolescents with asthma reported positive beliefs about tobacco products and were more likely to report living with individuals who used cigarettes (31.5%), hookah (12.1%), and e-cigarettes (15.5%) compared with their peers (26.5%, 8.5%, 12.5%, respectively). CONCLUSIONS: Adolescents with asthma reported tobacco product use, positive beliefs about tobacco products, and high potential home exposure to tobacco products. There is a pressing need for education regarding potential harm of alternative tobacco products among adolescents with asthma.

Working with Climate Projections to Estimate Disease Burden: Perspectives from Public Health.

There is interest among agencies and public health practitioners in the United States (USA) to estimate the future burden of climate-related health outcomes. Calculating disease burden projections can be especially daunting, given the complexities of climate modeling and the multiple pathways by which climate influences public health. Interdisciplinary coordination between public health practitioners and climate scientists is necessary for scientifically derived estimates. We describe a unique partnership of state and regional climate scientists and public health practitioners assembled by the Florida Building Resilience Against Climate Effects (BRACE) program. We provide a background on climate modeling and projections that has been developed specifically for public health practitioners, describe methodologies for combining climate and health data to project disease burden, and demonstrate three examples of this process used in Florida.
