Objective: We studied the night sleep duration in modern pupils and its impact on the state of health, formation of neurotic manifestations, mental efficiency, and fatigue in them.
Materials and methods: Components of daily regime, state of health of the children were studied by the questionnaire method; manifestations of neurotic disorders - with the help of the Childrens Questionnaire of Neuroses, and a stage of fatigue by the Andropova classical methodology with our supplements. We performed a correlative analysis and calculated a force of isolated factors effect.
Results: 11.4% of junior school age children, 23.5% of middle school age children, and 21.9% of senior school age ones have the sufficient night sleep duration. The components of mental efficiency both body of performed work and number of mistakes (p < 0.001) were sensitive to the factor of night sleep duration. At the deficiency of sleep a probability of a high degree of fatigue in the pupils is by 30% higher than at the sufficient sleep duration (p < 0.01). Reduction of night sleep leads to the deterioration of the state of health in the pupils (p < 0.001), in the group of girls, it is connected with the beginning of neurotic disorders (tendency to depression, asthenia, behavior violation, vegetative disorders) (p < 0.01-0.001). Recommended duration of night sleep is not less than 10 hours for the pupils of 1-4 grades, 9 hours for the students of 5-9 grades, and 8 hours for the students of 10-11 grades.
