Title Two years follow up of pulmonary values among welders in New Zealand
Bibliographic information May 1999, Vol.56, No.5, p.328-333. 26 ref.
Abstract A two-year follow up of pulmonary function and respiratory symptoms was carried out among 54 welders and 38 non-welders in eight New Zealand welding sites. 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 annual decline in FEV1 than non-welders, who had a slight non-significant annual increase. 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 (FEV1) than welders with protection. Among welders a significant association was found between the acute across shift change and the annual decline in FEV1. Chronic bronchitis was more common among welders than non-welders. Only one welder but eight non-welders reported having asthma. Welders who smoked and welders working without local exhaust ventilation or respiratory protection have an increased risk of accelerated decline in FEV1.
