Questo studio pubblicato da ricercatori di Taiwan ( dove  da poco promulgato una legge che pone divieto di utilizzo degli I-PAD sotto i 2 anni), si registra un aumento statisticamente significativo di emicrania e cefalea del +42% e di prurito/formicolio cutaneo + 84%, in bambini utilizzatori di telefono cellulare in una fascia di età compresa tra gli 11 ed i 14 anni.

Lo studio tende a suggerire la necessità di un uso più cauto dei telefoni cellulari nei bambini, perché in prospettiva sono tenuti ad una esposizione in vita ai campi elettromagnetici a radiofrequenza (RF-EMF) più a lungo rispetto agli adulti.

Abstract

 

BACKGROUND/PURPOSE:

To investigate the mobile phone (MP) use for talking in relation to health symptoms among 2042 children aged 11-15 years in Taiwan.

METHODS:

A nationwide, cross-sectional study, using the computer assisted telephone interview (CATI) technique, was conducted in 2009 to collect information on children's utilization of MPs and the perceived health symptoms reported by their parents.

RESULTS:

The overall prevalence of MP use in the past month was estimated at 63.2% [95% confidence interval (CI) = 61.1-65.3%]. MP use was associated with a significantly increased adjusted odds ratio (AOR) for headaches and migraine (1.42, 95% CI = 1.12-1.81) and skin itches (1.84, 95% CI = 1.47-2.29). Children who regularly used MPs were also considered to have a health status worse than it was 1 year ago (β = 0.27, 95% CI = 0.17-0.37).

CONCLUSION:

Although the cross-sectional design precludes the causal inference for the observed association, our study tended to suggest a need for more cautious use of MPs in children, because children are expected to experience a longer lifetime exposure to radiofrequency electromagnetic fields (RF-EMF) from MPs.
