Geographical pattern of brain cancer incidence in the Navarre and Basque Country regions of Spain.

Background: The study of the distribution of brain cancer mortality in Spain shows a grouping of highest risk provinces corresponding to the autonomous regions of Navarre and the Basque Country.

Aim: To explore the possible existence of geographical patterns in these areas.

Methods: Municipal maps of brain cancer incidence were drawn up and the influence of land use related variables on the distribution of the disease duly analysed.

Bladder cancer and coffee consumption in smokers and non-smokers in Spain.

The association between coffee consumption and bladder cancer was investigated in a multi-centre case-control study conducted in Spain from 1983 to 1986. A total of 497 cases (438 male and 59 female) with histopathologically confirmed bladder cancer were used in the analysis along with 566 hospital controls and 547 population controls. Odds ratios (OR), adjusted for age, province of residence, occupations at risk, consumption of artificial sweeteners and cigarette smoking, did not show any association between coffee consumption and bladder cancer for either sex.

[The evolution of mortality from ischemic heart disease in Basque Country 1975-1990].

Background: Given the importance of ischemic cardiopathy (IC) as a cause of death in industrialized countries, the trend of mortality by IC in people from 30 to 69 years of age residing in the Basque Country between 1975-1990 were studied. Furthermore, the evolution of the mortality by cardiac diseases and by other causes which may compete with IC in the certification or coding of the cause of death was studied.

Methods: The rate of mortality standardized by age by the direct methods were estimated from data from the Natural Movement of Population.

Tobacco smoke inhalation pattern, tobacco type, and bladder cancer in Spain.

The association between tobacco smoking and bladder cancer was investigated in a multicenter case-control study conducted in five provinces of Spain between 1983 and 1986. A matched analysis was carried out in males, based on 430 histologically confirmed cases, 405 hospital controls, and 386 population controls, matched by age and place of residence. An increased risk was found for smokers as compared with nonsmokers (odds ratio (OR) = 3.

Diet and bladder cancer in Spain: a multi-centre case-control study.

A multi-centre case-control study on bladder cancer and diet was carried out in 5 regions of Spain. We report results on 432 male cases and 792 matched controls. Usual dietary habits were investigated by means of an interview-based dietary history questionnaire.
