Arterial stiffness, oxidative stress, and smoke exposure in wildland firefighters
Gaughan DM , Siegel PD , Hughes MD , Chang CY , Law BF , Campbell CR , Richards JC , Kales SF , Chertok M , Kobzik L , Nguyen PS , O'Donnell CR , Kiefer M , Wagner GR , Christiani DC . Am J Ind Med 2014 57 (7) 748-56 OBJECTIVES: To assess the association between exposure, oxidative stress, symptoms, and cardiorespiratory function in wildland firefighters. METHODS: We studied two Interagency Hotshot Crews with questionnaires, pulse wave analysis for arterial stiffness, spirometry, urinary 8-iso-prostaglandin F2alpha (8-isoprostane) and 8-hydroxy-2'-deoxyguanosine (8-OHdG), and the smoke exposure marker (urinary levoglucosan). Arterial stiffness was assessed by examining levels of the aortic augmentation index, expressed as a percentage. An oxidative stress score comprising the average of z-scores created for 8-OHdG and 8-isoprostane was calculated. RESULTS: Mean augmentation index % was higher for participants with higher oxidative stress scores after adjusting for smoking status. Specifically for every one unit increase in oxidative stress score the augmentation index % increased 10.5% (95% CI: 2.5, 18.5%). Higher mean lower respiratory symptom score was associated with lower percent predicted forced expiratory volume in one second/forced vital capacity. CONCLUSIONS: Biomarkers of oxidative stress may serve as indicators of arterial stiffness in wildland firefighters. |
The economic burden of all-terrain vehicle related adult deaths in the U.S. workplace, 2003-2006
Helmkamp JC , Biddle E , Marsh SM , Campbell CR . J Agric Saf Health 2012 18 (3) 233-43 The objective of this study was to estimate the societal economic burden associated with work-related ATV fatalities among civilian persons more than 17 years of age in the U.S. from 2003 through 2006. ATV death data were obtained from the Bureau of Labor Statistics' annual Census of Fatal Occupational Injuries. Costs were estimated using a model employing a cost-of-illness method developed by the National Institute for Occupational Safety and Health. From 2003 to 2006, a total of 129 work-related ATV deaths occurred among persons more than 17 years of age in the U.S., nearly doubling from 20 deaths in 2003 to 39 deaths in 2006. The collective lifetime cost of the deaths was $103.6 million (M), with a four-year mean of $803,100 and a four-year median of $772,100. Decedents age 35 to 54 years accounted for one-third of the deaths (n = 41) at a cost of $50.1 M. Montana had the most deaths (13). Fifty-two percent of the deaths were overturns costing $48.3 M. Eighty-four (65%) of the deaths were workers in agricultural production at a cost of $62.3 M. Short-term investment in prevention measures, such as training and helmets for workers, could provide lasting dividends by preventing work-related ATV deaths and reducing their economic impact. |
State-specific ATV-related fatality rates: an update in the new millennium
Helmkamp JC , Aitken ME , Graham J , Campbell CR . Public Health Rep 2012 127 (4) 364-74 OBJECTIVES: We compared state-specific all-terrain vehicle (ATV) fatality rates from 2000-2007 with 1990-1999 data, grouping states according to helmet, training, and licensure requirements. METHODS: We used the CDC WONDER online database to identify ATV cases from 2000-2007 and calculate rates per 100,000 population by state, gender, and age. RESULTS: ATV deaths (n=7,231) occurred at a rate of 0.32 per 100,000 population. Males accounted for 86% of ATV-related deaths at a rate that was six times that for females (0.55 vs. 0.09 per 100,000 population, respectively); 60% of the male deaths occurred in the 15- to 44-year age group. With the exception of the two oldest age categories, rates were consistently higher in the no-helmet-law group. Both the number and rate of ATV-related deaths increased more than threefold between 1990-1999 and 2000-2007. West Virginia and Alaska continue to have the highest ATV fatality rates (1.63 and 2.67 ATV deaths per 100,000 population, respectively). CONCLUSIONS: Helmet-use requirements seem to slightly mitigate ATV-related death, but training requirements do not. For policy to be effective, it must be enforced. |
