Time trend in incidence of malignant neoplasms of the central nervous system in relation to mobile phone use among young people in Japan
Sato Y et al
Bioelectromagnetics 2016: in press
This is an ecological study that investigated whether there is an increase in incidence of cancer of the central nervous system (CNS) since the introduction of mobile phones in Japan. The information on mobile phone use was gathered via internet polling from 7,550 volunteers who were born before 2005. The incidence in CNS cancer has increased significantly in men and women aged 20-29 years (annual percent change, APC = 3.9%, 95% confidence interval, 95% CI = 1.6 – 6.3 in men and APC = 12.3%, 95% CI = 3.3-22.1) and 30-39 years (APC = 2.7%, 95% CI = 1.3 – 4.1 in men and APC = 3.0%, 95% CI = 1.4 – 4.7 in women) from 1993 to 2010 in Japan. The authors also calculated the expected incidence assuming that the relative risk was 1.4 for those who used mobile phones more than 1640 h cumulatively (classified as heavy use) as reported in the INTERPHONE study. The observed incidence was lower than the expected incidence if the association reported in the INTERPHONE study was true. Hence the authors concluded that the increase in incidence of CNS cancer among young people in Japan was unlikely to be caused by heavy mobile phone use.

Bioelectromagnetics 2016: in press
The Advanced Research on Interaction Mechanisms of electroMagnetic exposures with Organisms for Risk Assessment (ARIMMORA) project is a risk assessment funded by the European Commission to review the association between extremely low frequency (ELF) magnetic fields (MF) and childhood leukaemia after the International Agency for Research on Cancer (IARC) classified ELF MF as "possibly carcinogenic to humans" in 2002. Overall, the project found that there is a limited evidence of carcinogenicity in humans and inadequate evidence of carcinogenicity in experimental animals, with only weak supporting evidence from mechanistic studies, which confirms the validity of the IARC classification. The ARIMMORA project found that if the association is established, up to 2% of childhood leukaemia cases in Europe would be attributable to ELF-MF.
A paper published by the same main author in 2011 (reported in October 2011’s report) that reviewed a number of studies investigating ELF-MF and childhood cancers found that the assessment of ELF MF as a possible carcinogen was valid, mainly based on epidemiological evidence. It was found that more than 20 epidemiological studies have shown an association with relatively high consistency. Schuz et al estimated in 2011 that if there was a cause and effect relationship between ELF MF and childhood leukaemia, about 1% of all childhood leukaemia cases are attributable to ELF MF in Europe, and about 3% in North America.
The latest finding from the ARIMMORA project has estimated that up to 2% of childhood leukaemia cases in Europe will be caused by higher than typical ELF MF exposure (4 milligauss, mG and above), if the cause and effect relationship is assumed. The project acknowledged that the continuing existence of scientific uncertainty is dissatisfactory for public health messaging. However the continuing uncertainty is justified by the fact that although some epidemiological studies support a possible association with childhood leukaemia this is not supported by experimental studies.
Disturbed sleep in individuals with Idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF): Melatonin assessment as a biological marker
Andrianome S et al
Bioelectromagnetics 2016: in press
This is a case-control study which investigated whether the symptoms of electromagnetic hypersensitivity (EHS) are associated with melatonin levels. Thirty people with EHS (cases) were matched to twenty five healthy individuals (controls). The level of melatonin and sleep quality (assessed via questionnaires) were compared in the two groups. No significant difference was found in the melatonin levels in the two groups despite the difference in the sleep quality (people with EHS reported lower sleep quality).
Does chronic exposure to mobile phones affect cognition?
Mohan M et al
Funct Neurol 2016; 31 (1): 47 - 51
p>This is a cross-sectional study that aimed to assess the effects of RF exposure on cognition. A total of ninety participants aged 17-25 years were divided equally into 3 groups according to their mobile phone use: less than 5 years, more than 5 years, and no mobile phone use. The electroencephalography (EEG) analysis revealed that there was no significant difference among the three groups. The authors concluded that long-term mobile phone use does not affect cognition.
Effects of cell phone use on semen parameters: results from the MARHCS cohort study in Chongqing, China
Zhang G et al
Environ Int 2016; 91 : 116 - 121
This is a cohort study that investigated the effects of mobile phone use on male reproductive health. A total of 794 college students were included in the study in 2013 and they were reassessed in 2014 and 2015 (the loss of follow up was around 16% and 28% in 2014 and 2015, respectively). The information on mobile phone use was self-reported and the semen parameters including sperm count, volume and concentration were analysed. The authors reported that the mobile phone call duration using mobile phones was significantly associated with decreased semen parameters and thus concluded that mobile phone use may impair male fertility.
The effect of prenatal exposure to 1800 MHz electromagnetic field on calcineurin and bone development in rats
Erkut A et al
Acta Cir Bras 2016; 31 (2): 74 - 83
This is an animal study that investigated whether radiofrequency (RF) exposure causes any effects in the development of the offspring. A total of 16 pregnant rats were divided into 4 groups: exposed to either 0, 6, 12, or 24 hours a day. Details of the exposure received by the animals were not provided by the study. The exposure was at a frequency of 1800 megahertz and maximum power output of 2 Watts. The bone development of the male offspring was then evaluated after 60 days of birth. The authors reported that RF exposure during the prenatal period may inhibit bone and muscle tissue development.
Use of mobile and cordless phones and cognition in Australian primary school children: a prospective cohort study
Redmayne M, Smith CL, Benke G, Croft RJ, Dalecki A, Dimitriadis C, Kaufman J, Macleod S, Sim MR, Wolfe R, Abramson MJ
Environ Health 2016; 15 (1): 26
This Australian cohort study investigated whether there is an association between wireless phone use and cognitive function in children. The cohort included a total of 619 children aged 8-11 years from schools in Melbourne and Wollongong. Information on mobile and cordless phone use was obtained via questionnaires and the children were tested for cognitive function. Overall, there was no support of an association between wireless phones use and cognitive function in primary school-aged children.
This paper reported the results that were obtained at the start of the cohort study (baseline), which will be compared to the results obtained at a later time (after a period of follow-up).
As commented on January 2016’s report, studies investigating cognitive effects of mobile phone use on children have yielded inconsistent results so far.
Obtaining information via questionnaires can produce information bias. In this study by Redmayne et al, it was interesting to note that many children reported themselves as using a mobile phone whereas the parents reported that they were not using it.
Another interesting finding was that there was a significant difference in the reaction time (which is a measured parameter of cognitive function) on one of the tasks between girls and boys (gender effects), which may warrant further investigation.
Calcium homeostasis and low-frequency magnetic and electric field exposure: A systematic review and meta-analysis of in vitro studies
Golbach LA et al
Environ Int 2016: in press
This paper described the results of a systematic review and meta-analysis of in vitro studies that investigated the association between extremely low frequency (ELF) magnetic fields (MF) and calcium homeostasis (which is an indicator of efficient signalling between cells in the body). The systematic review, which included a total of 42 studies, showed evidence of an association. The meta-analysis revealed that there was a statistically significant effect of ELF MF exposure on both the frequency of calcium oscillations and intracellular calcium levels. Although the results supported an association between ELF MF exposure and calcium homeostasis, the authors noted that high heterogeneity in the different studies weakened the findings.
Dispositional aspects of body focus and idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF)
Domotor Z et al
Scand J Psychol 2016: in press
This is a human provocation study that investigated whether electromagnetic fields (EMF) exposure is associated with adverse health symptoms. A total of 72 people (36 claiming to have electromagnetic hypersensitivity, EHS, and 36 controls) were given sham exposure to an MF source (the participants were blinded to the exposure). Anxiety, EMF-related worries, and other subjective symptoms were assessed via questionnaires. People who claimed to have EHS reported more symptoms and had higher levels of anxiety than the controls. The authors suggested that somatosensory amplification is the biggest contributor to EHS.
Effects of radiation from a radiofrequency identification (RFID) microchip on human cancer cells
Lai HC et al
Int J Radiat Biol 2016: 1 - 6
This is an in vitro study that investigated whether radiofrequency (RF) exposure has any effects on cancer cells. Three types of human cancer cells (leukaemia, breast cancer, and hepatic cancer cells) were exposed to RF via the RF identification (RFID) microchip technology. The exposure was at a frequency of 134.2 kilohertz (kHz) and no exposure level was indicated. Four experiment settings were compared which involved all possible combinations of inactive/active activator (where the signal is generated) and with/without microchip. The authors found that the RF exposure emanating from the active microchip slowed down the growth of cancer cells.
