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. On each stage of the study were made medical examinations with paraclinical ones /blood and urine/, and during every school year information has been gathered for all cases of acute diseases. It was established that the health status of the examined schoolchildren of I-III class of the unified secondary polytechnical schools, evaluated on the basis of data taken from the acute and chronic somatic diseases is good. There are no abrupt differences in the health of both compared groups of schoolchildren. A slight tendency for deterioration of the health is observed among those starting school at 6 years.
本研究旨在探讨在每周五天制学校及全天组织教学过程的条件下，新型统一中等专业技术学校（USPS）的培训对一至三年级、初始入学年龄为6岁和7岁的学生健康状况的影响。对索非亚和布尔加斯6个班级学童的健康状况进行了纵向观察（从一年级到三年级），观察对象为6岁开始上学的儿童（实验组）和7岁开始上学的儿童（对照组）。此外，还对全国10个地区的1657名一至三年级学生进行了横向调查，6岁和7岁的学童按相同方式分布。在研究的每个阶段都进行了包括辅助临床检查（血液和尿液检查）在内的医学检查，并在每个学年收集了所有急性疾病病例的信息。结果表明，根据急慢性躯体疾病数据评估，统一中等专业技术学校一至三年级受检学童的健康状况良好。两组相比较的学童在健康方面没有明显差异。6岁开始上学的儿童中观察到健康状况略有恶化的趋势。
