OBJECTIVE: To characterize the correlates of pulmonary function in urban police officers; an occupational group exposed to increased work-related stressors and environmental risk factors. METHODS: We calculated the percent of predicted values of forced expiratory volume in 1 second (FEV1%), forced vital capacity (FVC%), and FEV1%/FVC% in a random sample of police officers (n = 58) in the Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study, and a comparison sample from the Buffalo, New York general population (n = 967; employed, CVD-free). We used simple linear regression to estimate coefficients between pulmonary function measures and potential correlates. RESULTS: Mean values of pulmonary function were: police officers, 41.5 years, FEV1% = 102.2 +/- 12.5, FVC% = 102.5 +/- 13.3; general population, 46.6 years, FEV1% = 100.1 +/- 14.2, FVC% =100.8 +/- 13.5. In simple linear regression models, abdominal height (beta = -0.98), current smoking (beta = -1.97, compared to non-smokers), systolic blood pressure (beta = -0.07) and glucose (beta = -0.28) were associated with lower FEV1% in police. Associations of similar magnitude were obtained for the correlates of pulmonary function in the general population, with the exception of glucose (beta = -0.05). CONCLUSION: While police officers are a unique occupational cohort, the correlates of pulmonary function were similar to the general population sample. Additionally, the 5-fold larger inverse association of glucose level with pulmonary function in police officers may warrant further study.
