Women in coal mining-radiographic findings of women participants in the Coal Workers' Health Surveillance Program 1970-2022
Hall NB , Myers NT , Reynolds LE , Blackley DJ , Laney AS . J Womens Health (Larchmt) 2024 Objective: To describe the work experience and respiratory health of women coal miners in the United States using Coal Workers' Health Surveillance Program (CWHSP) data. Methods: Analysis included CWHSP participants with self-reported sex of female between January 1, 1970, and December 31, 2022, and examined radiographic surveillance, demographics, and job history. National Institute for Occupational Safety and Health-certified physicians classified chest radiographs. Results: Among 8,182 women participants, most worked <10 years and a majority reported working in non-dusty jobs. Among 3,392 with ≥1 year of coal mining tenure, 18 (0.5%) had evidence of pneumoconiosis, with no cases of progressive massive fibrosis. Conclusion: Women coal miners participating in the CWSHP had short mining careers and low pneumoconiosis prevalence. Few worked in the most dusty jobs, indicating limited exposure to coal mine dust. This underscores the need to explore women's roles in mining, and for improved gender-specific employment reporting. Such changes can enhance health and work conditions for women in male-dominated industries. |

Rogers TM , Robinson SJ , Reynolds LE , Ladva CN , Burgos-Garay M , Whiteman A , Budge H , Soto N , Thompson M , Hunt E , Barson T , Boyd AT . J Public Health Manag Pract 2021 28 (1) 60-69 OBJECTIVE: To identify potential strategies to mitigate COVID-19 transmission in a Utah meat-processing facility and surrounding community. DESIGN/SETTING: During March-June 2020, 502 workers at a Utah meat-processing facility (facility A) tested positive for SARS-CoV-2. Using merged data from the state disease surveillance system and facility A, we analyzed the relationship between SARS-CoV-2 positivity and worker demographics, work section, and geospatial data on worker residence. We analyzed worker survey responses to questions regarding COVID-19 knowledge, beliefs, and behaviors at work and home. PARTICIPANTS: (1) Facility A workers (n = 1373) with specimen collection dates and SARS-CoV-2 RT-PCR test results; (2) residential addresses of all persons (workers and nonworkers) with a SARS-CoV-2 diagnostic test (n = 1036), living within the 3 counties included in the health department catchment area; and (3) facility A workers (n = 64) who agreed to participate in the knowledge, attitudes, and practices survey. MAIN OUTCOME MEASURES: New cases over time, COVID-19 attack rates, worker characteristics by SARS-CoV-2 test results, geospatially clustered cases, space-time proximity of cases among workers and nonworkers; frequency of quantitative responses, crude prevalence ratios, and counts and frequency of coded responses to open-ended questions from the COVID-19 knowledge, attitudes, and practices survey. RESULTS: Statistically significant differences in race (P = .01), linguistic group (P < .001), and work section (P < .001) were found between workers with positive and negative SARS-CoV-2 test results. Geographically, only 6% of cases were within statistically significant spatiotemporal case clusters. Workers reported using handwashing (57%) and social distancing (21%) as mitigation strategies outside work but reported apprehension with taking COVID-19-associated sick leave. CONCLUSIONS: Mitigating COVID-19 outbreaks among workers in congregate settings requires a multifaceted public health response that is tailored to the workforce. IMPLICATIONS FOR POLICY AND PRACTICE: Tailored, multifaceted mitigation strategies are crucial for reducing COVID-19-associated health disparities among disproportionately affected populations. |
COVID-19 Vaccine Second-Dose Completion and Interval Between First and Second Doses Among Vaccinated Persons - United States, December 14, 2020-February 14, 2021.
Kriss JL , Reynolds LE , Wang A , Stokley S , Cole MM , Harris LQ , Shaw LK , Black CL , Singleton JA , Fitter DL , Rose DA , Ritchey MD , Toblin RL . MMWR Morb Mortal Wkly Rep 2021 70 (11) 389-395 In December 2020, two COVID-19 vaccines (Pfizer-BioNTech and Moderna) received Emergency Use Authorization from the Food and Drug Administration.*(,)(†) Both vaccines require 2 doses for a completed series. The recommended interval between doses is 21 days for Pfizer-BioNTech and 28 days for Moderna; however, up to 42 days between doses is permissible when a delay is unavoidable.(§) Two analyses of COVID-19 vaccine administration data were conducted among persons who initiated the vaccination series during December 14, 2020-February 14, 2021, and whose doses were reported to CDC through February 20, 2021. The first analysis was conducted to determine whether persons who received a first dose and had sufficient time to receive the second dose (i.e., as of February 14, 2021, >25 days from receipt of Pfizer-BioNTech vaccine or >32 days from receipt of Moderna vaccine had elapsed) had received the second dose. A second analysis was conducted among persons who received a second COVID-19 dose by February 14, 2021, to determine whether the dose was received during the recommended dosing interval, which in this study was defined as 17-25 days (Pfizer-BioNTech) and 24-32 days (Moderna) after the first dose. Analyses were stratified by jurisdiction and by demographic characteristics. In the first analysis, among 12,496,258 persons who received the first vaccine dose and for whom sufficient time had elapsed to receive the second dose, 88.0% had completed the series, 8.6% had not received the second dose but remained within the allowable interval (≤42 days since the first dose), and 3.4% had missed the second dose (outside the allowable interval, >42 days since the first dose). The percentage of persons who missed the second dose varied by jurisdiction (range = 0.0%-9.1%) and among demographic groups was highest among non-Hispanic American Indian/Alaska Native (AI/AN) persons (5.1%) and persons aged 16-44 years (4.0%). In the second analysis, among 14,205,768 persons who received a second dose, 95.6% received the dose within the recommended interval, although percentages varied by jurisdiction (range = 79.0%-99.9%). Public health officials should identify and address possible barriers to completing the COVID-19 vaccination series to ensure equitable coverage across communities and maximum health benefits for recipients. Strategies to ensure series completion could include scheduling second-dose appointments at the first-dose administration and sending reminders for second-dose visits. |
Work practices and respiratory health status of Appalachian coal miners with progressive massive fibrosis
Reynolds LE , Blackley DJ , Colinet JF , Potts JD , Storey E , Short C , Carson R , Clark KA , Laney AS , Halldin CN . J Occup Environ Med 2018 60 (11) e575-e581 OBJECTIVE: To characterize workplace practices and respiratory health among coal miners with large opacities consistent with progressive massive fibrosis (PMF) who received care at a federally-funded black lung clinic network in Virginia. METHODS: Participants were interviewed about their workplace practices and respiratory health. Medical records were reviewed. RESULTS: Nineteen former coal miners were included. Miners reported cutting rock, working downwind of dust-generating equipment, non-adherence to mine ventilation plans (including dust controls), improper sampling of respirable coal mine dust exposures, working after developing respiratory illness, and suffering from debilitating respiratory symptoms. CONCLUSIONS: Consistent themes of suboptimal workplace practices contributing to development of PMF emerged during the interviews. Some of the practices reported were unsafe and unacceptable. Further research is needed to determine the prevalence of these factors and how best to address them. |

JAMA 2018 319 (5) 500-501 This study describes the demographic and radiographic characteristics of 416 coal miners with progressive massive pulmonary fibrosis (PMF) identified by pneumoconiosis screening as part of the US Coal Workers' Health Surveillance Program. |
Respiratory morbidity among U.S. coal miners in states outside of central Appalachia
Reynolds LE , Blackley DJ , Laney AS , Halldin CN . Am J Ind Med 2017 60 (6) 513-517 BACKGROUND: Recent NIOSH publications have focused on the respiratory health of coal miners in central Appalachia, yet 57% of U.S. coal miners work in other regions. We characterized respiratory morbidity in coal miners from these regions. METHODS: Active coal miners working outside of central Appalachia who received chest radiographs and/or spirometry during 2005-2015 were included. Chest radiographs were classified according to International Labour Office standards and spirometry was interpreted using the American Thoracic Society guidelines. Prevalence of coal workers' pneumoconiosis (CWP) and abnormal spirometry were compared by region. RESULTS: A total of 103 (2.1%) miners had CWP. The eastern region had the highest prevalence (3.4%), followed by the western (1.7%), and interior (0.8%) regions. A total of 524 (9.3%) miners had abnormal spirometry. CONCLUSIONS: CWP occurs in all U.S. coal mining regions. Prevalence of CWP was higher in the eastern region, but lower than levels reported in central Appalachia. |
Strengthening the Coal Workers' Health Surveillance Program
Reynolds LE , Wolfe AL , Clark KA , Blackley DJ , Halldin CN , Laney AS , Storey E . J Occup Environ Med 2017 59 (4) e71 In 2014, the Mine Safety and Health Administration (MSHA) issued a final rule1 requiring the National Institute for Occupational Safety and Health (NIOSH) to expand the coal workers’ health surveillance program (CWHSP). Since 1970, when it was established by the Coal Mine Health and Safety Act of 1969, the CWHSP has offered chest radiographs to US coal miners—primarily those working underground—to detect coal workers’ pneumoconiosis (CWP) early and prevent it from progressing to disabling disease. The expansion of the CWHSP adds periodic lung function testing (spirometry) and respiratory health assessment questionnaires, and extends its coverage to include surface coal miners. This will permit the early detection of lung function impairment secondary to chronic obstructive pulmonary disease, an important manifestation of coal mine dust lung disease that is not detected by chest radiography. | On October 24, 2016, in accordance with the MSHA rule, NIOSH published a final rule2 updating medical surveillance for coal miners. NIOSH collaborated with MSHA, mine operators, clinics, medical device manufacturers, and other stakeholders to develop a framework to meet its new mandate. All clinics participating in the CWHSP, including new spirometry clinics, must be approved by NIOSH to ensure clinic personnel are trained, equipment and procedures are standardized, and miners’ health information can be securely collected and transmitted to NIOSH. |
