Title A 56-year mortality follow-up of Texas petroleum refinery and chemical employees, 1948-2003
Bibliographic information May 2007, Vol.49, No.5, p.557-567. 48 ref.
Abstract This study updates an earlier investigation on the mortality risk of employees of a refinery and petrochemical complex in Texas, United States, by extending the follow-up until 2003. The cohort consisted of 10,621 employees with an average follow-up of 34 years. Standardized mortality ratios (SMRs) adjusted for age, race and calendar years were used as a measure of risk. Overall mortality (SMR 0.77), all cancer mortality (SMR 0.87) and most cause-specific mortalities were lower than or similar to those of the surrounding population. The only statistically significant excess of mortality found in this study was an increase in mesothelioma among maintenance employees; the SMR was 4.78 among employees who worked for a minimum of one year and was 7.51 among those with 10 or more years of employment and 20 or more years of latency.
