Silicosis mortality trends and new exposures to respirable crystalline silica - United States, 2001-2010
Bang KM , Mazurek JM , Wood JM , White GE , Hendricks SA , Weston A . MMWR Morb Mortal Wkly Rep 2015 64 (5) 117-120 Silicosis is a preventable occupational lung disease caused by the inhalation of respirable crystalline silica dust and can progress to respiratory failure and death. No effective specific treatment for silicosis is available; patients are provided supportive care, and some patients may be considered for lung transplantation. Chronic silicosis can develop or progress even after occupational exposure has ceased. The number of deaths from silicosis declined from 1,065 in 1968 to 165 in 2004. Hazardous occupational exposures to silica dust have long been known to occur in a variety of industrial operations, including mining, quarrying, sandblasting, rock drilling, road construction, pottery making, stone masonry, and tunneling operations. Recently, hazardous silica exposures have been newly documented during hydraulic fracturing of gas and oil wells and during fabrication and installation of engineered stone countertops. To describe temporal trends in silicosis mortality in the United States, CDC analyzed annual multiple cause-of-death data for 2001-2010 for decedents aged ≥15 years. During 2001-2010, a total of 1,437 decedents had silicosis coded as an underlying or contributing cause of death. The annual number of silicosis deaths declined from 164 (death ratedagger = 0.74 per 1 million population) in 2001 to 101 (0.39 per 1 million) in 2010 (p = 0.002). Because of new operations and tasks placing workers at risk for silicosis, efforts to limit workplace exposure to crystalline silica need to be maintained. |
Prevalence of obesity by occupation among US workers: the National Health Interview Survey 2004-2011
Gu JK , Charles LE , Bang KM , Ma CC , Andrew ME , Violanti JM , Burchfiel CM . J Occup Environ Med 2014 56 (5) 516-28 OBJECTIVE: To estimate the prevalence of obesity and the change of prevalence of obesity between 2004-2007 and 2008-20011 by occupation among US workers in the National Health Interview Survey. METHODS: Self-reported weight and height were collected and used to assess obesity (body mass index ≥ 30 kg/m). Gender-, race/ethnicity-, and occupation-specific prevalence of obesity were calculated. RESULTS: Prevalence of obesity steadily increased from 2004 through 2008 across gender and race/ethnicity but leveled off from 2008 through 2011. Non-Hispanic black female workers in health care support (49.2%) and transportation/material moving (46.6%) had the highest prevalence of obesity. Prevalence of obesity in relatively low-obesity (white-collar) occupations significantly increased between 2004-2007 and 2008-2011, whereas it did not change significantly in high-obesity (blue-collar) occupations. CONCLUSIONS: Workers in all occupational categories are appropriate targets for health promotion and intervention programs to reduce obesity. |
Diseases attributable to asbestos exposure: years of potential life lost, United States, 1999-2010
Bang KM , Mazurek JM , Wood JM , Hendricks SA . Am J Ind Med 2013 57 (1) 38-48 BACKGROUND: Although asbestos use has been restricted in recent decades, asbestos-associated deaths continue to occur in the United States. OBJECTIVES: We evaluated premature mortality and loss of potentially productive years of life attributable to asbestos-associated diseases. METHODS: Using 1999-2010 National Center for Health Statistics mortality data, we identified decedents aged ≥25 years whose death certificate listed asbestosis and malignant mesothelioma as the underlying cause of death. We computed years of potential life lost to life expectancy (YPLL) and to age 65 (YPLL65 ). RESULTS: During 1999-2010, a total of 427,005 YPLL and 55,184 YPLL65 were attributed to asbestosis (56,907 YPLL and 2,167 YPLL65 ), malignant mesothelioma (370,098 YPPL and 53,017 YPLL65 ). Overall and disease-specific asbestos-attributable total YPLL and YPLL65 and median YPLL and YPLL65 per decedent did not change significantly from 1999 to 2010. CONCLUSIONS: The continuing occurrence of asbestos-associated diseases and their substantial premature mortality burden underscore the need for maintaining prevention efforts and for ongoing surveillance to monitor temporal trends in these diseases. |
Chronic obstructive pulmonary disease prevalence among nonsmokers by occupation in the United States
Bang KM , Syamlal G , Mazurek JM , Wassell JT . J Occup Environ Med 2013 55 (9) 1021-6 OBJECTIVE: To examine the prevalence of chronic obstructive pulmonary disease (COPD) among nonsmokers by occupation in the United States. METHODS: The 1997 to 2004 National Health Interview Survey data for working adults aged 25 years or more were used to estimate the COPD prevalence and to examine change in COPD prevalence between 1997 to 2000 and 2001 to 2004 by occupational groups. RESULTS: During 1997 to 2004, COPD prevalence was 2.8%. The COPD prevalence was highest in financial records processing (4.6%) occupations. There was a slight increase in COPD prevalence during the two survey periods from 2.8% during 1997 to 2000 compared with 2.9% during 2001 to 2004. CONCLUSIONS: No significant changes in the COPD prevalence between the two periods were found. Nevertheless, the elevated COPD prevalence in certain occupational groups suggests that other risk factors play a role in developing COPD. |
Associations between psychological distress and body mass index among law enforcement officers: the National Health Interview Survey 2004-2010
Gu JK , Charles LE , Burchfiel CM , Andrew ME , Ma C , Bang KM , Violanti JM . Saf Health Work 2013 4 (1) 52-62 OBJECTIVES: To investigate the association between psychological distress and obesity among law enforcement officers (LEOs) in the United States. METHODS: Self-reported data on psychological distress based on six key questions were obtained from LEOs who participated in the National Health Interview Survey (2004-2010). We used Prochaska's cut-point of a Kessler 6 score ≥ 5 for moderate/high mental distress in our analysis. Mean levels of body mass index (BMI) were compared across three levels of psychological distress. RESULTS: The average age of LEOs (n = 929) was 39.3 years; 25% were female. Overall, 8.1% of LEOs had moderate or high psychological distress; 37.5% were obese (BMI ≥ 30). Mean BMI increased with increasing psychological distress (no distress, BMI = 27.2 kg/m(2); mild distress, 27.6 kg/m(2); and moderate/high distress, 33.1 kg/m(2); p = 0.016) after adjustment for age, race, income, and education level among female officers only. Physical activity modified the association between psychological distress and BMI but only among male LEOs (interaction p = 0.002). Among male LEOs reporting low physical activity, psychological distress was positively associated with BMI (30.3 kg/m(2) for no distress, 30.7 for mild distress, 31.8 for moderate/high distress; p = 0.179) after adjustment, but not significantly. This association was not significant among males reporting high physical activity. CONCLUSION: Mean BMI significantly increased as psychological distress increased among female LEOs. A longitudinal study design may reveal the directionality of this association as well as the potential role that physical activity might play in this association. |
Silicosis mortality with respiratory tuberculosis in the United States, 1968-2006
Nasrullah M , Mazurek JM , Wood JM , Bang KM , Kreiss K . Am J Epidemiol 2011 174 (7) 839-48 The presence of tuberculosis (TB) in patients with silicosis increases mortality risk. To characterize silicosis-respiratory TB comortality in the United States, the authors used 1968-2006 National Center for Health Statistics multiple cause-of-death data for decedents aged ≥25 years. The authors calculated proportionate mortality ratios (PMRs) using available information on decedents' industries and occupations reported from 26 states from 1985 through 1999. Among 16,648 silicosis deaths, 2,278 (13.7%) had respiratory TB listed on the death certificate. Of silicosis-respiratory TB deaths, 1,666 decedents (73.1%) were aged ≥65 years, 2,255 (99.0%) were male, and 1,893 (83.1%) were white. Silicosis-respiratory TB deaths declined 99.5% during the study period (P < 0.001 for time-related trend), from 239.8 per year during 1968-1972 to 1.2 per year during 2002-2006, with no reported deaths in 2006. Silicosis-respiratory TB deaths reported from Pennsylvania (n = 525; 1.29 per million population), Ohio (n = 258; 0.81 per million), and West Virginia (n = 146; 2.35 per million) accounted for 40.8% of all such deaths in the United States. The highest PMR for silicosis-respiratory TB death was associated with the "miscellaneous nonmetallic mineral and stone products" industry (PMR = 73.7, 95% confidence interval: 33.8, 139.8). In the United States, 2006 marked the first year since 1968 with no silicosis-respiratory TB deaths. The substantial decline in silicosis-respiratory TB comortality probably reflects prevention and control measures for both diseases. |
Prevalence of chronic obstructive pulmonary disease in the U.S. working population: an analysis of data from the 1997-2004 National Health Interview Survey
Bang KM , Syamlal G , Mazurek JM . COPD 2009 6 (5) 380-7 To estimate the prevalence and the population attributable fraction of chronic obstructive pulmonary disease (COPD) in the U.S. adult workers, we analyzed data obtained from the National Health Interview Surveys for the period 1997-2004. The overall COPD prevalence was 4.0% (95% confidence interval [CI] 3.9-4.1%). The prevalence was higher in females (5.4%, 95% CI 5.3-5.6%) than in males (2.8%, 95% CI 2.7-2.9%); in Whites (4.2%, 95% CI 4.1-4.3%) than in Blacks (3.4%, 95% CI 3.1-3.7%) and other races (2.4%, 95% CI 2.1-2.8%). Compared with insurance, real estate and other finance industry, the top three industries associated with significantly higher prevalence odds ratios (PORs) (adjusted for age, sex, race, and smoking) were other educational services (POR = 1.5, 95% CI 1.0-2.3); transportation equipment (POR = 1.4, 95% CI 1.1-1.8); and social services, religious and membership organizations (POR = 1.4, 95% CI 1.1-1.7). Compared with managers and administrators, except public administration occupation, the top three occupations with significantly higher PORs were health service (1.8, 95% CI 1.5-2.1), other protective service (POR = 1.6, 95% CI 1.2-2.2), and material moving equipment operators (POR = 1.6, 95% CI 1.1-2.3). The overall population attributable fraction for association of COPD with employment was 12.2% for industry and 17.4% for occupation. Further studies are needed to determine specific risk factors associated with COPD in industries and occupations with elevated prevalence and POR. |
Prevalence of lifetime asthma and current asthma attacks in U.S. working adults: an analysis of the 1997-2004 National Health Interview Survey data
Syamlal G , Mazurek JM , Bang KM . J Occup Environ Med 2009 51 (9) 1066-74 OBJECTIVE: To estimate national prevalences of lifetime asthma and asthma attacks among workers by age, sex, race, occupation and industry, and estimate population attributable fraction to employment for asthma attacks in the United States. METHODS: The 1997-2004 National Health Interview Survey data for currently working adults aged > or = 18 years were analyzed. RESULTS: Lifetime asthma prevalence was 9.2%; the social services religious and membership organizations industry and the health service occupation had the highest asthma prevalence. Asthma attack prevalence among workers with asthma was 35.4%; the primary metal industry and the health assessment and treating occupation had the highest attack prevalence. Approximately, 5.9% of cases reporting an asthma attack were attributed to employment when considering industries and 3.8% when considering occupations. CONCLUSIONS: Future studies and intervention strategies should address the higher prevalence of asthma in certain industries and occupations. |
