“…Кроме того, в отличие от других исследователей, которые применяли более точные, инструментальные методы оценки когнитивных функций [8,9], мы использовали субъективную оценку в виде жалоб на забывчивость и невнимательность. С небольшим периодом наблюдения, вероятно, связано и то, что мы не обнаружили описанного в литературе [2,5,9]…”

“…Современные научные данные свидетельствуют о неблагоприят ном влиянии сверхвысокочастотного (СВЧ) электромагнитного излучения МТ на здоровье школьников. В эпидемиологических исследованиях детей и подростков выявлена связь между интенсивностью разговоров по МТ и частотой жалоб на головные боли [2][3][4][5], головокружения [4,6], нарушения сна [2,4,5,7], утомляемость [4,[7][8][9][10][11], психоэмоциональные нарушения [4,7,10,12], связь с простудными заболеваниями [2,5], нарушением когнитивных функций [4,8,9]. Частота жалоб на самочувствие у детей и подростков тем выше, чем дольше и интенсивнее они используют МТ.…”

“…Оценка влияния мобильной связи на самочувствие осложняется тем, что сами режимы разговоров по МТ и уровень его излучения меняются в процессе его использования. Известно, что по мере роста и взросления дети чаще и дольше ежедневно говорят по МТ [2,5], переходят к использованию более современных моделей МТ, в частности смартфонов, уровень СВЧ-излучения которых ниже, чем у старых «кнопочных» моделей [15]. С появлением мобильного Интернета (МИ) дети в большей степени начинают использовать МТ в качестве мультимедийного средства, а не для голосового общения [16].…”

Background: Significant changes in the methods and modes of mobile phone (MP) use in modern primary schoolchildren and insufficient knowledge of their health consequences have determined the relevance and purpose of this study. Objective: To assess the dynamics of MP use in primary school students and its impact on children’s well-being. Materials and methods: In 2017–2019, changes in the type of MP, modes of voice communication and mobile Internet (MI) use, and the dynamics of the health symptoms frequency were assessed in the prospective cohort study of 47 primary schoolchildren (25 boys and 22 girls) using questionnaires. MP radiation levels were measured for 23 children. Results: During the observation period, we noted a decrease in the level of MP radiation (p = 0.002); an increase in the proportion of children using MI (from 57.4 to 85.1 %, p = 0.006) and in the frequency (p = 0.002) and duration (p = 0.01) of MI use; keeping MP closer to the body in the daytime (p = 0.01). By the end of the study, we observed an increase in the proportion of children with clinically significant symptoms (CSS) of sleep disturbance (from 23.4 to 40.4 %, p = 0.025) and anxiety (from 2.12 to 12.8 %, p = 0.043). The decrease in MP radiation levels accompanied by an increase in the frequency and duration of MI use correlated with the replacement of the “push-button” MP with a smartphone. The switch to smartphone and MI usage was associated with an increase in CSS of anxiety (p = 0.02) and difficulty falling asleep (p = 0.043). Conclusion: The study showed that in modern junior schoolchildren aged 7–10 with a short experience of MP usage, transition to using a MP as a multimedia device is a more important factor in impairment of well-being than the duration and intensity of MP voice communication.

Modern telecommunication technologies rely on using radio-frequency electromagnetic field (RF EMF). They have brought many useful services into our life able to solve multiple issues. However, we should bear in mind that this exposure is open, uncontrollable and permanent. Given that, it seems relevant to investigate possible negative influence exerted by RF EMF on health of children and adolescents since this population group is the most vulnerable and sensitive to any external exposure. This review analyzes Russian and foreign studies with their focus on chronic influence of RF EMF created by cellular communication means on health of children (aged 6–10 years) and adolescents (aged 11–16 years). We have established several manifestations of health disorders in children and adolescents including asthenic syndrome (headache, irritability, increased fatigue, sleeping disorders, periodical pains in the heart and joints); mental deadaptation (anxiety, stress, depression, etc.); as well as their combinations. Along with all the aforementioned syndromes, effects produced by exposure to RF EMF become apparent through some indirect signs of memory and attention failure such as forgetfulness (inability to recall the necessary information in time) and inattention (inability to concentrate on an event or activity) and even through growing frequency of respiratory diseases. Basing on the analyzed studies by Russian and foreign researchers, we can conclude that they provide solid evidence of negative influence of electromagnetic fields created by cell phones on health of children and adolescents. Therefore, implementation of modern gadgets and their active use by children and adolescents should be accompanied with assessment of actual threats posed by them, health risk assessment, and development of scientifically substantiated standards for their safe use.

“…It is noteworthy that students who use MEDs often have asthenopic complaints, functional state of their eyes (organs of sight) and musculoskeletal system is impaired, and they tend to suffer from developing psychological dependence etc. [3][4][5][6][7][8].…”

Many research works have described negative effects produced by use of electronic devices, mobile ones (smartphone, tablets) included, on children, adolescents and youth. However, the problem has many aspects and not all of them have been explored profoundly. In this study, our aim was to conduct hygienic assessment of routine use of mobile electronic devices by schoolchildren and students and to give grounds for its correction by hygienic education. By conducting a survey, we obtained data on use of mobile electronic devices by 1218 schoolchildren and students both in their educational and spare time activities and created a profile of a work and rest routine when working with mobile electronic devices. 943 students and schoolchildren were examined by an ophthalmologist. Next, issues related to hygienic education were integrated into the training program for medical students at the Hygiene Department of the Pirogov Russian National Research Medical University. The emphasis was on creating a safe routine of using mobile electronic devices. Schoolchildren and students who adhered to a healthy work and rest routine when working with mobile electronic devices complained about health disorders authentically less frequently (p ≤ 0.05).We established a statistically significant relative risk for visual acuity if schoolchildren and students did not pursue a safe routine of using mobile electronic devices. Its level was RR = 3.07 (95 % CI =1.88–5.03). By the end of hygienic studies with their focus on creating a safe routine of using mobile electronic devices, medical students had an authentic (p ≤ 0.05) increase in visual acuity due to decline in such states as routine accommodative excess and pre-myopia. Work and rest routines accepted by children, adolescents and youth when they use mobile electronic devices are a manageable risk factor of health disorders in these population groups. This study shows that hygienic education may be quite effective for correcting a routine of using mobile electronic devices by schoolchildren and students.
