Abstract
Objective
To investigate whether interventions implemented by the UK Health and Safety Executive addressing exposure to isocyanate-based spray paints in motor vehicle repair (MVR), flour dust in craft bakeries, rosin-based solder flux fume in the electronics industry, metalworking fluids and wood dust coincided with a decline in incidence of work-related short latency respiratory disease or asthma in the target groups.
Method
Changes in the incidence of work-related short latency respiratory disease reported to a UK-based surveillance scheme were compared using a longitudinal, negative binomial regression model with ß distributed random effects. An interrupted time series design was used and comparisons according to inclusion or exclusion in the target group were made by including a statistical interactions expressed as a ratio of incidence rate ratios (RIRRs) in the model.
Results
The incidence of work-related short latency respiratory disease attributed to flour dust significantly increased relative to all other agents (RIRR: 1.10; 95% CI 1.06 to 1.16) whereas work-related short latency respiratory disease attributed to rosin-based solder flux fume significantly declined relative to all other agents (0.94; 0.90 to 0.99). No significant changes in the incidence of SLRD attributed to wood dust (1.03; 0.91 to 1.16) or spray paints (1.03; 0.95 to 1.11) relative to all other agents were observed. A higher proportion of reports originated from the industries targeted by the intervention for rosin-based solder flux fume (65/107; 61%) than spray painting (27/93; 27%) or wood dust (16/42; 38%).
Conclusions
These data support a beneficial effect of interventions to reduce exposure to rosin-based solder flux fume but an increase in work-related short latency respiratory disease attributed to flour dust may indicate increased exposure or increased awareness of the problem
