dc.description.abstract INTRODUCTION: Male UK professional divers have a higher prevalence of cognitive symptoms (18percent) than an age matched control group of Offshore Oil Industry workers (6percent) and this was associated with duration of diving career and experience of mixed gas bounce, surface oxygen decompression and saturation diving. The validity of this observation has been confirmed by objective neuropsychological testing and cerebral MRI studies. The original questionnaire data has been reanalysed to allow for potential confounding factors in the diving group. MATERIALS AND METHODS: 1540 professional divers responded to a postal questionnaire into lifestyle, health, work experience and work accidents. The presence or absence of moderate to extreme forgetfulness or loss of concentration was entered into a logistic regression model allowing for lifestyle factors, diving experience, work as a welder, decompression illness, other diving accidents and reported exposure to petrochemicals or hydrogen sulphide. RESULTS: 1442 cases were entered into the model with 98 cases excluded because of missing data. 262 subjects had cognitive symptoms. Results for significantly associated factors(p less than 0.05) are shown in the table. Factor Mean Odds Ratio 95percent CI for OR P, Age (years) 0.97 0.95-0.99 0.01, Binge drinking 0.02, never 1.00, less than monthly 1.81 1.02-3.21 0.04, 1-9 times per month 1.54 0.0.90-2.64 0.12, 10-20 times per month 2.03 1.10-3.77 0.02, greater than 20 times per month 3.21 1.56-6.61 0.002, Work as a welder 1.54 1.11-2.12 0.009, Mixed gas bounce (per 100 dives) 1.32 1.11-1.56 0.002, Neurological DCI 0.005, never 1.00, once 1.46 0.89-2.39 0.13, greater than once 2.87 1.45-5.66 0.002, Contaminated gas 0.01, never 1.00, once 1.19 0.81-1.73 0.39, greater than once 1.77 1.21-2.60 0.00, Petrochemicals 0.02, never 1.00, a little 1.09 0.70-1.68 0.72, a lot 1.79 1.06-3.01 0.03, CONCLUSIONS: Cognitive symptoms in professional divers may be largely explained by age, alcohol consumption, work as a welder, exposure to chemicals and neurological decompression illness. en_US
