Introduction: The present study was a comprehensive study that assessed the effects of exposure to mobile phone radiation on Body weight and Body Composition as well as assessing the critical indicators associated with Body Composition. Methods: Twenty rats weighing 200+10g at 4 to 6 weeks of age were individually housed in cages. The rats were randomly divided into the following two groups of 10 animals each: the control group and an exposure group that underwent electromagnetic wave radiation for 4 hours once a day for five weeks. The exposure was given by mobile phone having a specific absorption rate (SAR) of 0. 90 watts/kg. Results: There were no significant differences in mean changes in weight, height, lee index, and chest between the two groups. No significant differences were detected in fat mass, lean mass, and total mass of exposure and control groups at the end of the study. There were no significant differences among groups in FBS, lipid profile, thyroid hormone, kidney function, and appetite-regulating hormones. Conclusions: The current study showed that exposure to mobile phone radiations for 4 hours once a day for five weeks (SAR of 0. 90 Watt/kg) has no adverse effects on the thyroid, kidney functions, and hormonal profiles as well as Body weight and Body Composition.
