Background: Per-and polyfluoroalkyl substances (PFAS), are ubiquitous pollutants associated with adverse health outcomes. High PFAS levels have been demonstrated among career firefighters; less is known about PFAS levels among volunteer firefighters who comprise two-thirds of US firefighters. Methods: Volunteer fire department members completed a survey and provided blood samples. We calculated geometric means and 95% CIs for PFAS reported by the National Health and Nutrition Examination Survey (NHANES). We compared PFAS distribution and levels among non-Hispanic white adult male study participants to those in the 2015–2016 and 2017–2018 NHANES cycles. We assessed associations between PFAS serum levels and years of firefighting controlling demographics and occupation using linear regression. Results: Participant’s average age was 46.6 years (sd. 17.1). Perfluorododecanoic acid (PFDoA) was detected in almost half study but <3% of NHANES participants; serum levels of PFDoA, perfluorononanoic acid (PFNA), and perfluorodecanoic acid (PFDA) were elevated among participants compared with NHANES. Serum levels of both PFDA and PFDoA were positively associated with years of firefighting. Conclusions: Volunteer firefighters may have a different serum profile and levels of PFAS than the general population. Future work in this area should include volunteer firefighters from other geographic locations and assess sources of PFAS exposure.
Objective: There is a growing literature on the risk of chronic disease among firefighters, including cardiovascular disease (CVD) and cancer. However there is little information on firefighter's perception thereof. Methods: Firefighters attending a union convention in New Jersey completed a survey with four domains: firefighting experience; perceived additional risk for chronic diseases (six-point Likert scale); cancer screening history; demographics, and risk behaviors. Results: Among 167 enrolled firefighters, all were men and 86.6% active career. Median perceived risk ranged from high risk (colon, hematologic, breast, prostate, and testicular cancers) to very high risk (CVD, pulmonary diseases, all cancers, lung and oral cancer). Conclusions: NJ Firefighters attributed considerable additional risk to acquiring chronic disease as a result of their firefighting activities. Understanding firefighter perceptions of their own morbidity and mortality will help develop future firefighter preparatory programs.
Background: There is an increasing concern over adolescent concussions in sports due to risks of long-term negative effects. This study analyzed data over three school years on reported concussion incidence rates by season, high school grade levels and gender, and reported symptoms by school nurses versus athletic trainers, from New Jersey student-athlete concussion data available from an online school-based surveillance system. Methods: School nurses and athletic trainers reported 300 concussions within five days from when each occurred over three school years, 2015-2018, in team sports and physical education in New Jersey high schools. Analysis was further conducted on symptoms and number of symptoms reported by school nurses versus school athletic trainers for each documented student-athlete concussion. Estimated concussion incidence rates were calculated using state agency verified school enrollment data. Findings: Concussions most commonly occurred during fall, followed by spring, then winter. Concussion incidence rates ranged from 6.3/1000 (4.99, 7.55) -9.1/1000 (7.27, 10.98) students over the three school years of the study. Athletic trainers completed 86% of the reports while nurses completed 11% (position or title of 3%, or n = 7, were not disclosed); the values were similar when considering only fall pre-season and regular season sports (88, 10, 2%, respectively). On average, across the three school years, athletic trainers reported about 3.5 symptoms per report while nurses reported 2.7 (values in fall seasons only were 3.7 and 3.1, respectively.) Conclusions: Certified athletic trainers, compared to school nurses, more often completed concussion report forms and reported more symptoms per injured student, perhaps due partly to closer contact and immediate care provided after injury. Additionally, this study had a higher concussion incidence rate during fall sports seasons compared to winter and spring. Future research can further improve our understanding of concussions among adolescent student-athletes to better inform concussion identification, management and recovery protocols.
Objective: To characterize the diet of volunteer firefighters compared with the United States recommended dietary intake. Methods: A survey was administered to members of volunteer fire department which collected information on demographics, behavioral risks, fire service history, and dietary intake using the Dietary Screener Questionnaire. Dietary intake was compared with US recommendations; associations between dietary intake and years of firefighting, were assessed using bi- and multivariate analysis. Results: The 122 male study participants were majority non-Hispanic white (96.4%), and over 90% were overweight or obese. Participants had lower mean intakes of fruit and vegetables, whole grains, and dietary fiber, and a higher mean intake of added sugars compared with the US recommended dietary intake. Conclusion: Volunteer firefighters in our study had suboptimal daily dietary intake of fruits and vegetables, dietary fiber, whole grains, and added sugars.
Background: Assessing aspects of intersections that may affect the risk of pedestrian injury is critical to developing child pedestrian injury prevention strategies, but visiting intersections to inspect them is costly and time-consuming. Several research teams have validated the use of Google Street View to conduct virtual neighborhood audits that remove the need for field teams to conduct in-person audits. Methods:We developed a 38-item virtual audit instrument to assess intersections for pedestrian injury risk and tested it on intersections within 700 meters of 26 schools in New York City using the Computer Assisted Neighborhood Visual Assessment System (CANVAS) with Google Street View imagery.Results: Six trained auditors tested this instrument for inter-rater reliability on 111 randomly selected intersections and for test-retest reliability on 264 other intersections. Inter-rater kappa scores ranged from −0.01 to 0.92, with nearly half falling above 0.41, the conventional threshold for moderate agreement. Test-retest kappa scores were slightly higher than but highly correlated with inter-rater scores (spearman rho=0.83). Items that were highly reliable included presence of a
BACKGROUND New Jersey (NJ) Safe Schools Program, primarily funded by the NJ Department of Education, has aims concerning safety and health including helping to alleviate harassment, intimidation, and bullying (HIB) in secondary school because HIB can affect learning. We evaluated officially reported adolescent HIB total incidents and estimated rates in NJ public city and county school districts for the 2011‐2016 school years. METHODS A cross‐sectional observational study using population‐based state‐reported public data. We calculated point prevalence and incidence rates for K‐12 students in 22 public city school districts, students in 21 career‐technical‐vocational education (CTE) school districts, and 8 special services school districts during 2011‐2016. RESULTS HIB is prevalent in NJ school classrooms. HIB comprised ≥75% of total officially reported in‐school violence‐related incidents in a given school year. Rates per 100 enrollees of total officially reported incidents for the 5‐year period of 2011‐2016 was highest in special services school districts (5.00; 95% confidence interval [CI]: 4.67, 5.34) followed by CTE districts (1.94; 95% CI: 1.86, 2.01), and lowest in city districts (1.46; 95% CI: 1.44, 1.48). The special services school district also had the highest rates per year and the 5‐year period. CONCLUSIONS Data analyses suggested ideas for further research and improvements for school HIB incident reports. Policies and programs could remedy issues observed in state secondary school classrooms. Best practices within districts and schools can help protect students from HIB and promote safety, health, learning, and maturation.
