[Health status of 1st- to 3d-grade pupils in a unified secondary polytechnical school entering school at different ages].

The purpose of the present work is to study the effect of training in the new unified secondary polytechnical school /USPS/ on the health status of students from I-III class, with initial school age 6 and 7 years, realized in the conditions of 5-day school week and all day organization of the training process. A longitudinal observation /I to III class/ on the health status of 6 divisions of schoolchildren in Sofia and Burgas is performed--on those starting at the age of 6 /experimental/ and 7 years /controls/. Besides a transversal investigation of a total number of 1657 students of I-III class in 10 districts of the country was carried out, distributed in like manner between 6 and 7 years old schoolchildren.

[Health status of 6- and 7-year-old 1st-graders studying under the new program of the Ministry of Public Education].

Medical follow-up was realized, during the first school year, on six- and seven-years old, first grade school-children, with the purpose to study effect on the health state of the training accordint to the new programme of Ministry of Education. Both groups of school-children observed, were trained according to identical plans and programmes but the organization of the school environment and regimen of the six-year old pupils were more favourable from sanitaryhygienic point of view (smaller number of pupils in the classes, more favourable microclimate in the class rooms, school furniture consistent with the age, conditions for afternoon sleep). A tendency to relatively better hialth state among the 6-years old, first grade pupils was established within the frames of the first grade, regardless of their younger age.

[Hygienic and physiological evaluation of the instruction during a 5-day school week].

A longitudinal study of development, reactivity and health state of the students from the initial course, trained during five- and six-day school week was carried out under conditions of full-day organization of the training-educational work. Deviations in the hygienic norms of some moments of daily regime, some results from the dynamics of working capacity and high neurotic morbidity with both forms of organization of trainingeducational work, necessitate essential corrections for its rationalization. Apart from all that, the parallel between the results from the examination of the students, trained during five- and six-day school week in the course of three school years, definitely indicate the following: better working capacity towards the end of school day and week, circulation, realized on a more rational base, better strength indices, lower moment somatic affection and acute morbidity, low number of often-sick-students and more completely healthy students, twice lower neurotic morbidity in favour of the students with a five-day school regime.
