BACKGROUND Increased brain tumour risk after head trauma suggested by case reports and clinical series has been previously studied epidemiologically with mixed results. An international multicentre case-control study investigated the role of head trauma from injury or sports participation in adult brain tumour risk. METHODS In all, 1178 glioma and 330(More)
AIMS To explore cancer risk from date of birth until 1994 in children, born 1958 or later, of Swedish male pesticide applicators. METHODS Records of male pesticide applicators licensed 1965-76 were linked to the Multigeneration Register. The records of their offspring were then linked to the Swedish Cancer Registry and the Cause of Death Register. (More)
The association between X-ray exposure in utero and childhood cancer was studied in a case-control study, nested in a national cohort of Swedish twin births. Records of the Swedish Twin Register for those born 1936-1967 (n = 83,316) were linked to the Swedish Cancer Register (1958-1983) and the Swedish Cause-of-Death Register (1952-1983). Ninety-five cases(More)
The majority of suspected occupational risk factors for adult brain tumours have yet to be confirmed as etiologically relevant. Within an international case-control study on brain tumours, lifelong occupational histories and information on exposures to specific substances were obtained by direct interviews to further investigate occupational risk factors(More)
The aim of the study was to determine the incidence of hospital care with the diagnosis rheumatoid arthritis (RA) among patients with schizophrenia, affective psychosis and neurosis compared with that among hospitalized patients in general. By means of the in-patient register of Stockholm County, a cohort was formed comprising all patients discharged with(More)
Fifty-six per cent of invited women aged 25-60 attended the Population-based Cervical Cancer Screening Programme (PCCSP) in Stockholm, Sweden in 1994-1996. The objective of this study was to explore factors related to participation in this PCCSP. Registry data on all women aged 25-60 invited to the PCCSP from 1994 to 1996 (n=307,552) was matched with a(More)
The aim of the study was to investigate the importance of diagnostic dental radiography and amalgam fillings as risk factors for tumours of the central nervous system (CNS). This population-based case-control study included subjects aged 25-74 years, living in the catchment area of the Neurosurgery Department of Uppsala University Hospital in Sweden. A(More)
While numerous studies have addressed the possible role of farming and related exposures as risk factors for brain tumours in adults, few of them have examined the potential effect of exposure to farm animals or pets. In an international multicentre case-control study, we investigated whether residence on a farm, contact with animals, or working in(More)
As part of a skin cancer control programme, we studied the occurrence of self-reported outdoor tanning, sunbed use and ultraviolet (UV)-induced erythema in an urban area. A cross-sectional questionnaire study of 6000 adolescents aged 13-19 years, and 4000 adults aged 20-50 years was applied. Non-response was analysed for outdoor tanning and sunbed use.(More)
Occupations with exposure to magnetic fields were studied in a population-based case-control study of male glioma and meningioma in Central Sweden. The study included 84 cases of glioma, 20 cases of meningioma and 155 controls. Information about job titles was obtained by means of a questionnaire. Three different methods were used to classify exposure 1)(More)
