  1. Two year follow up of pulmonary function values among welders in New Zealand.

    Article - En anglais

    Objectives-To examine whether welding is a risk factor for an accelerated decline in pulmonary function.

    Methods-2 Year follow up of pulmonary function and respiratory symptoms among 54 welders and 38 non-welders in eight New Zealand welding sites.

    Results

    There were no significant differences in age, height, smoking habits, ethnicity, or total time in industrial work between welders and non-welders.

    No overall differences were noted in the changes of pulmonary function variables between the two study groups.

    However, when the comparison was restricted to smokers, welders had a significantly greater (p=0.02) annual decline (88.8 ml) in FEV, than non-welders, who had a slight non-significant annual increase (34.2 ml).

    Also, welders without respiratory protection or local exhaust ventilation while welding had a greater annual decline both in forced vital capacity (FVC) and forced expiratory volume in one second (FEV,) than welders with protection (p=0.001 and 0.04, respectively).

    Among welders a significant association was found between the acute across shift change and the annual decline in FEV, Chronic bronchitis was more common among welders (24%) than non-welders (5%). Only one welder (2%) but eight non-welders (21%) reported having asthma.

    Conclusions-Welders who smoked and welders working without local exhaust ventilation or respiratory protection have an increased risk of accelerated decline in FEV1.
