Objective: We performed a hygienic assessment of factual nutrition of schoolchildren and determined its impact on mental efficiency in middle-age and senior school age children.

Materials and methods: Features of nutrition were studied by means of the questioning of 462 schoolchildren in 5th 11th grades in the city of Kyiv. Mental efficiency was investigated with the help of corrective tests with a further statistic processing of all obtained data.

Results: Factual nutrition of modern schoolchildren is characterized by the insufficient consumption of such foodstuffs as meat, butter, eggs, dairy produce in 22 % of the children, fish and sea products in 60 % of the children. In general the malnutrition is typical for 19 % of middle-age schoolchildren and 16 % of senior age ones. Results of integral assessment showed that a number of children with malnutrition increased and decreased with optimum nutrition from 5th to 9th grades (p < 0,001). A connection of the increase of the productivity of mental efficiency with a growth of integral assessment of nutrition was established (rs = 0.12; p < 0.001). Isolated contribution of nutrition factor in the productivity of mental efficiency is 7.3 0.4 % (p<0.01). Probability of the high level of fatigue in the schoolchildren is 1.3 times as high at malnutrition than at the optimum nutrition (<0.05).
