Abstract
We investigated the effects of socioeconomic, demographic and health-related indicators on the incidence of and survival from tumours of the central nervous system (CNS) diagnosed in 1994–2003 with follow-up through 2006 in Denmark using information from nationwide Danish administrative registers. The analyses were based on data on 5622 patients with CNS tumours in a cohort of 2.7 million people born between 1925 and 1973 and aged ⩾30 years. Socioeconomic and demographic factors were not associated with the incidence of CNS tumours, except for a significantly increased incidence rate ratio (IRR) amongst men in the agricultural class (IRR, 1.23; 95% CI, 1.04–1.45). The 1- and 5-year survival was significantly longer in higher socioeconomic groups, as assessed by education, income, affiliation to the work market and size of dwelling.
