The Wildland Firefighter Exposure and Health Effect (WFFEHE) Study: Rationale, design, and methods of a repeated-measures study

Ann Work Expo Health 2021 66 (6) 714-727 The wildland firefighter exposure and health effect (WFFEHE) study was a 2-year repeated-measures study to investigate occupational exposures and acute and subacute health effects among wildland firefighters. This manuscript describes the study rationale, design, methods, limitations, challenges, and lessons learned. The WFFEHE cohort included fire personnel ages 18-57 from six federal wildland firefighting crews in Colorado and Idaho during the 2018 and 2019 fire seasons. All wildland firefighters employed by the recruited crews were invited to participate in the study at preseason and postseason study intervals. In 2019, one of the crews also participated in a 3-day midseason study interval where workplace exposures and pre/postshift measurements were collected while at a wildland fire incident. Study components assessed cardiovascular health, pulmonary function and inflammation, kidney function, workplace exposures, and noise-induced hearing loss. Measurements included self-reported risk factors and symptoms collected through questionnaires; serum and urine biomarkers of exposure, effect, and inflammation; pulmonary function; platelet function and arterial stiffness; and audiometric testing. Throughout the study, 154 wildland firefighters participated in at least one study interval, while 144 participated in two or more study interval. This study was completed by the Centers for Disease Control and Prevention's National Institute for Occupational Safety and Health through a collaborative effort with the U.S. Department of Agriculture Forest Service, Department of the Interior National Park Service, and Skidmore College. Conducting research in the wildfire environment came with many challenges including collecting study data with study participants with changing work schedules and conducting study protocols safely and operating laboratory equipment in remote field locations. Forthcoming WFFEHE study results will contribute to the scientific evidence regarding occupational risk factors and exposures that can impact wildland firefighter health over a season and across two wildland fire seasons. This research is anticipated to lead to the development of preventive measures and policies aimed at reducing risk for wildland firefighters and aid in identifying future research needs for the wildland fire community. |
Noise-induced hearing loss in agriculture: creating partnerships to overcome barriers and educate the community on prevention
Ehlers JJ , Graydon PS . Noise Health 2011 13 (51) 142-6 Noise-induced hearing loss (NIHL) is a common and preventable injury for farmers. Farmers are frequently exposed to excessive noise, ranking among the top three occupations and industries with the highest risk for hearing loss. Use of hearing protection among farmers is not common. Although the age when NIHL begins among farmers is unknown, its prevalence is higher among male adolescents who live and work on farms. The purpose of this paper is to describe how NIOSH created partnerships to promote hearing conservation for this hard-to-reach population. Partnerships included organizations and individuals who were trusted sources of information for the target population, young farmers 14-35 years of age and their families, and those who had linkages in rural communities. NIOSH engaged partners through exhibits and train-the-trainer workshops at state or national conventions. NIOSH workshops included basic information on NIHL as well as information on free or low-lost resources that participants could use in training others at schools and community events. People with hearing conservation expertise have an important role and many opportunities to improve the knowledge and implementation of hearing conservation among those in agriculture. |
Hearing loss prevention for carpenters: part 2 - demonstration projects using individualized and group training
Stephenson MR , Shaw PB , Stephenson CM , Graydon PS . Noise Health 2011 13 (51) 122-31 Two demonstration projects were conducted to evaluate the effectiveness of a comprehensive training program for carpenters. This training was paired with audiometry and counseling and a survey of attitudes and beliefs in hearing loss prevention. All participants received hearing tests, multimedia instruction on occupational noise exposure/hearing loss, and instruction and practice in using a diverse selection of hearing protection devices (HPDs). A total of 103 apprentice carpenters participated in the Year 1 training, were given a large supply of these HPDs, and instructions on how to get additional free supplies if they ran out during the 1-year interval between initial and follow-up training. Forty-two participants responded to the survey a second time a year later and completed the Year 2 training. Significant test-retest differences were found between the pre-training and the post-training survey scores. Both forms of instruction (individual versus group) produced equivalent outcomes. The results indicated that training was able to bring all apprentice participants up to the same desired level with regard to attitudes, beliefs, and behavioral intentions to use hearing protection properly. It was concluded that the health communication models used to develop the educational and training materials for this effort were extremely effective. |
