Oral cancer: material deprivation, unemployment and risk factor behaviour--an initial study

Regional variations in the incidence of oral cancer may be related in some cases to material deprivation. The main aim of this study was to identify in cases (and controls matched for age and sex) an index of material deprivation, employment history, smoking and alcohol habits. This prospective study comprised 100 subjects in each group and was questionnaire based. Previous studies in relation to material deprivation in oral cancer have been population based. There was a statistically significant trend for patients to come from the most deprived groups. Sixty-six per cent of the cases had experience of long-term unemployment. Although a high proportion, this was not statistically significant after multi-variable analysis due to the confounding effects of smoking and alcohol use. Such a high proportion of cases with a history of long-term unemployment requires further study to examine in detail if there is a definite link with oral cancer once the confounding effects of smoking and alcohol are removed.
