Women exposed to aromatic solvents while working as painters, sculptors or lab technicians are at high risk of lung function decline and obstructive airways disease, Australian research shows.
Men are also at risk of lung function decline through occupational exposure to aromatic solvents in painting, electrical, mining and construction trades, according to novel findings from the Tasmanian Longitudinal Health Study (TAHS).
The population-based longitudinal study included 767 people who underwent lung function testing at the ages of 45 and 50.
Based on their lifetime work history records, exposure to aromatic solvents was found to be associated with a 15.5 mL/year greater decline in FEV1 and 14.1 mL/year greater decline in FVC compared to people who had no occupational exposure to solvents.
The analysis, conducted by researchers at Melbourne University’s School of Population and Global Health also found that cumulative exposure to aromatic solvents was also associated with greater decline in FEV1 and FVC. Importantly, women were significantly more susceptible than men to cumulative exposure to solvents.
Despite women having lower cumulative exposure to aromatic solvents compared with men, they showed a greater decline in FEV1 and FEV1/FVC ratio for a given increase in exposure. The study authors said the gender difference in lung function susceptibility to aromatic solvents might be due to different patterns of occupational exposure.
