Aim Determination and estimation of risk degree of the factors in the chronic respiratory disease outbreak.
Methods To study the risk factors it was applied the discriminate analysis, which consists in determining of aggression of various risk factors by rendering of share. Shares were determined based on the relative and attributable risk for each risk factor separately.
Results The study presented a significant relationship between the children with chronic respiratory diseases and the low air temperatures in rooms (RR - 3,96, p < 0.001), increased relative humidity (RR - 2,41, p < 0.001) the presence of mould (RR - 2,27, p < 0.001), increased CO2 concentrations (RR - 1,76, p < 0.001). The results obtained in calculating the degree of risk attributable to reveal the likelihood of developing chronic respiratory pathology can be expected in children exposed to the following factors: low temperature air (RA-79.9%, p < 0.001), increased relative humidity (RA - 0.5%, p < 0.001), presence of mould (RA - 67.9%, p < 0.001), the concentration of CO2 (RA - 29.6%, p < 0.001), socio-economic level of the family (RA - 23.9%, p < 0.001) and passive smoking (8.6%, p < 0.001).
Conclusion According to the analysis of relations between pupils’ health state indices with chronic respiratory diseases and the factors of educational and residential medium based on the calculation of relative risk, attributable risk the main predictors of the environment are: low air temperature in rooms, high humidity, damp, mould, major CO2 concentration, lack of ventilation in houses and classrooms. The action of multitude risk factors in combination enhances the development and the onset of these diseases.
