[Hygienic assessment of textbooks for educational establishments of different types].
The role of hygienic parameters of prints in the development of fatigue and this or that abnormality in schoolchildren of today has been inadequately studied. Practically every three or two textbooks on the humanities, analyzed by the authors, show breaches of the orders of educational publishing products; they are much less significantly encountered in the textbooks on natural sciences and, in isolated instances, in those on mathematical sciences. Thus, due to the variations in their weight, the lettering of a body text, high component complexity and abstractedness, the textbooks are a risk factor for visual, nervous, and musculoskeletal diseases among pupils of educational establishments, particularly those of the innovation type. The problems associated of the present-day textbook are of no hygienic order, although they may exert a considerable impact on pupils' efficiency.
