[Health status of dwellers of cities and towns with developed chemical industry].

Assessing the physical development of children residing in the developed chemical industrial town has revealed that more than a fourth of the children examined are abreast of their biological age and that there is a trend for reducing the number of those who have the level of biological development which corresponds to their age. In the total morbidity pattern among children, respiratory diseases rank first, whose proportion increases in the higher air-polluted areas. A comprehensive assessment shows that the overwhelming majority (88-93%) belong to Health Groups II-IY, which is indicative of the unfavourable environmental factors of the town.
