Health risk assessment among younger schoolchildren in conditions of distance learning

Objective: based on a hygienic assessment of the conditions and organization of distance learning, to establish the main risk factors for the health of younger students. Material and methods. 276 junior schoolchildren from St. Petersburg and the Leningrad region were examined. The study of the organization and conditions of distance learning, and the subjective assessment of well-being was carried out by the method of questioning. The study of the dynamics of the functional state of the body of schoolchildren was carried out before and afterthe lesson of the Russian language with ophthalmic non-ergonomic visual material, implemented through an electronic learning tool. Results. Thus, in the group of children, the chances and risks of a change in well-being are higher with an irrational organization of connection to the Internet (RR=1.904, OR=3.139), the development of mental fatigue is higher in schoolchildren who study in an unfavorable light environment (RR=1.809, OR= 5.125), nervous fatigue is formed more often in schoolchildren who study through non-rational electronic means (RR=3.869, OR=24.271). Conclusion. The study made it possible to establish the main risk factors that contribute to a change in the well-being and functional state of the body of younger schoolchildren when organizing distance learning - incorrect posture during training, not a rational type of electronic learning tool, not a rational type of Internet connection and not a favorable light environment in the room.
