Residential extremely low frequency magnetic fields and skin cancer.
Published in: Occup Environ Med 2021: oemed-2021-107776 [in press]
Aim of study (acc. to author)
Endpoint/type of risk estimation
list: categorization of all apartments in the buildings included in the Database of Finnish Buildings with Indoor
Transformer Stations (DaFBITS) according to their location in relation to the transformer room (located on ground floor or basement) (see Khan et al., 2020) Exposure groups
Reference group 1
apartment located on any other floor than the first or ground floors of the building
apartment located above the transformer station or sharing a wall with the transformer station
adults living in buildings with indoor transformer stations for at least 6 months and 18 years or older at the end of study (31.12.2016)
1971 - 2016
Finnish Cancer Registry
8,617 individuals in the
exposed group and 170,706 individuals in the reference group; total person-years of follow-up were 149,291 for the exposed residents and 2,967,986 for the referents
Statistical analysis method:
Cox proportional regressions analysis
age at start of residency and birth year
Conclusion (acc. to author)
Limitations (acc. to author)
A limitation of the study was the low number of cases, particularly in the analysis focusing on
Study funded by
University of Eastern Finland, Finland
