Title Exposure to benzene, occupational stress and reduced birth weight
Bibliographic information Oct. 2000, Vol.57, No.10, p.661-667. 40 ref.
Abstract The association between birth weight and exposure to benzene, work stress, and other occupational and environmental hazards was investigated among petrochemical industry workers. 792 pregnant workers were followed up through delivery between May 1996 and December 1998. Exposure to benzene and other solvents was assessed based on job titles and workplace information. Other occupational and environmental exposures and personal information were obtained by interview. Regression models were used to examine the individual and combined associations of occupational and environmental exposures with birth weight. Birth weight was negatively associated with exposure to benzene (-58g) and with work stress (-84g). There was a significant interaction between exposure to benzene and work stress relative to reduced birth weight. Adjusted mean birth weight was 3,445g among those with neither exposure, 3,430g for those with exposure to benzene only, 3,426g for those with work stress only, and 3,262g for those with both exposures.
