Title: [abstract] COGNITIVE SYMPTOMS IN PROFESSIONAL DIVERS WHO WORK AS WELDERS
Author: Ross, JA; Macdiarmid, JI; Semple, S; Crawford, JR
Abstract: BACKGROUND: The prevalence of cognitive symptoms in divers who have worked as a welder (DW) has been found to be 28 percent and this is higher than in other divers (15percent) or non-welders and non-divers (NDNW) (6percent). Our previous study also showed that welders who did not dive (NDW) also had an increase level of symptoms (11percent) but the number of this group (45) was insufficient to conclude that diver welders had more symptoms than non diver welders (1). MATERIALS AND METHODS: A life-style, health and work experience questionnaire was sent to 361 DW, 352 NDW and 503 NDNW. Included was a Cognitive Failure Questionnaire (CFQ) and a welding exposure questionnaire. RESULTS: Valid responses were obtained from 153 DW, 108 NDW and 252 NDNW. The prevalence of moderate to extreme forgetfulness or loss of concentration was higher in DW (34percent) than either NDNW (14percent) or NDW (10percent). CFQ scores were higher in DW (mean 40.3 95percent CI 37.8-42.7) than either NDNW (32.8, 31.1-34.5) or NDW (35.7, 32.8-38.5) indicating more cognitive symptoms. There was no differences between the non-diver groups. Welding exposure was lower in DW (p less than 0.001) and was not related to CFQ score either overall or at group level. 40percent of DW had not welded in a pressurized environment and they had the same prevalence of complaint (27percent) as divers who had welded at pressure (37percent p=0.25). Welding fume exposure (mg.m-3. days), Median (IQR), Non-diver welders 43,623 (15,933-82,485), Diver welders 13,471 (3,607-39,470) CONCLUSIONS: DW have more cognitive symptoms than NDW. Since welding and diving did not have to be conducted simultaneously for an effect to be seen, a simple interaction between the two factors is unlikely. (1) Macdiarmid J et al.
