Childhood central nervous system tumors and leukemia: Incidence and familial risk. A comparative population-based study in Utah and Norway.

Background: In this study, we aimed to evaluate incidence rates and family risk of the most common childhood cancers, tumors in the central nervous system (CNS), and leukemia among individuals from Norway and individuals with Scandinavian ancestry living in Utah.

Methods: We used the Utah Population Database and the Norwegian National Population Register linked to Cancer registries to identify cancers in children born between 1966 and 2015 and their first-degree relatives. We calculated incidence rates and hazards ratios.

Family history of cancer and risk of paediatric and young adult's testicular cancer: A Norwegian cohort study.

Background: The aim of this study was to examine the association of a family history of cancer with the risk of testicular cancer in young adults.

Methods: This is a prospective cohort study including 1,974,287 males born 1951-2015, of whom 2686 were diagnosed with TC before the age of 30.

Results: A history of TC in male relatives was significantly associated with a diagnosis of TC among children and young adults, including brothers (6.

The risk of cancer in the offspring and parental length of life.

Background: We investigated if cancer onset in offspring is related to having short-lived parents for different cancer types and to see if there was a difference in smoking- and non-smoking related cancers.

Methods: Our study included 524,391 individuals born in Norway 1940-1950. All children were followed up for cancer from the age of 20 until they were between 59 and 69 years.

Poverty and the risk of leukemia and cancer in the central nervous system in children: A cohort study in a high-income country.

Aims: The association between childhood cancer and socioeconomic status is inconclusive. Family income has seldom been included in large population-based studies, and the specific contributions of it remain unknown.

Methods: A total of 712,674 children born between 1967 and 2009 in the Oslo region were included.

Use of mobile phones in Norway and risk of intracranial tumours.

To test the hypothesis that exposure to radio-frequency electromagnetic fields from mobile phones increases the incidence of gliomas, meningiomas and acoustic neuromas in adults. The incident cases were of patients aged 19-69 years who were diagnosed during 2001-2002 in Southern Norway. Population controls were selected and frequency-matched for age, sex, and residential area.

Paternal occupational exposure to radiofrequency electromagnetic fields and risk of adverse pregnancy outcome.

Background: During the last decades, public concern that radiofrequency radiation (RFR) may be related to adverse reproductive outcomes has been emerging. Our objective was to assess associations between paternal occupational exposure to RFR and adverse pregnancy outcomes including birth defects using population-based data from Norway.

Methods: Data on reproductive outcomes derived from the Medical Birth Registry of Norway were linked with data on paternal occupation derived from the general population censuses.

Residential and occupational exposure to 50-Hz magnetic fields and brain tumours in Norway: a population-based study.

Our case-control study was conducted to investigate whether residential and occupational exposure to magnetic fields increased the risk for brain tumours in adults. Data from an occupational exposure matrix was also evaluated. The study population in this nested case-control study was made up of subjects aged 16 years and older who had resided in a broad corridor around a high-voltage power line in 1980 or during one of the years from 1986-1996.

Residence near power lines and the risk of birth defects.

Background: There has been some concern that exposure to electromagnetic fields may cause birth defects. We studied risks of birth defects by residential exposure to 50-Hz magnetic fields from power lines.

Methods: We estimated the distance between residence and power lines for 161,844 Norwegian residences, and their corresponding magnetic fields in the period 1980 to 1997.

Comparison of three different ways of measuring distances between residences and high voltage power lines.

The aim of this study was to evaluate whether distance data based on calculations by use of digitalized geographical information systems (GIS) and distance data based on measurements on 1:5000 maps agree sufficiently with on site distance measurements to be used as input to magnetic field calculations in epidemiological studies. The analysis were performed by use of weighted kappa (kappa(w)) statistical method described by Bland and Altman for comparison of measures of agreement. Map measurements showed better agreement with on site measurements than GIS calculations did.
