| Model | 900 MHz (GSM), 2 GHz (UMTS) mobile phone use by adolescents in Sweden and correlation with subjective complaints. | |
| Details | Adolescents (15-19 yrs) in Sweden (n = 1270) were sent a questionnaire regarding their use of mobile phones and various subjective complaints. The authors report a high percentage of mobile phone use in the respondents that increased with age (55.6% of 15 yr olds, 82.2% of 19 yr olds). Girls used more than boys, and 17.4% of respondents used headsets all the time. Watching TV increased the probability of using mobile and cordless phones. The authors report some indication of an association with tiredness, stress, headache, anxiety, concentration difficulties, and sleep disturbances. The authors do indicate the initial study was explorative and may be open to bias and confounding. In a subsequent study, blood samples from self reported electromagnetically hypersensitive individuals (n = 13) were collected and analyzed by high resolution gas chromatography and high resolution mass spectrometry to detect the concentration of several common organic pollutants (as compared with 21 control samples). The authors report generally higher concentrations of PCBs in the hypersensitive group, with chlordane MC6 (OR 11.2, 95% CI 1.18 - 106) and PBDE #47 (OR 11.7, 95% CI 1.45-94.7) being statistically significant. Other chlorinated hydrocarbons were also elevated but not to a statistically significant extent in the small sample population. The authors suggest such contaminants may be responsible for disorders that are attributed to other chemical or physical agents. AUTHORS' ABSTRACT: Hardell 2017 (IEEE #6765): The use of digital technology has grown rapidly during the last couple of decades. During use, mobile phones and cordless phones emit radiofrequency (RF) radiation. No previous generation has been exposed during childhood and adolescence to this kind of radiation. The brain is the main target organ for RF emissions from the handheld wireless phone. An evaluation of the scientific evidence on the brain tumor risk was made in May 2011 by the International Agency for Research on Cancer at World Health Organization. The scientific panel reached the conclusion that RF radiation from devices that emit nonionizing RF radiation in the frequency range 30 kHz300 GHz is a Group 2B, that is, a possible human carcinogen. With respect to health implications of digital (wireless) technologies, it is of importance that neurological diseases, physiological addiction, cognition, sleep, and behavioral problems are considered in addition to cancer. Well-being needs to be carefully evaluated as an effect of changed behavior in children and adolescents through their interactions with modern digital technologies. |
