Abstract

Objective: The research aimed to verify how the local climatic conditions can intensify the respiratory disease in children under five years, and circulatory and respiratory in adults sixty years and older. The sector south/southeast of São Paulo city from the association with the atmospheric variables and bioclimatic index PET (Physiological Equivalent Temperature). Methods: 12.269 cases respiratory diseases in children, 24 318 circulatory diseases and 8.894 respiratory tract in elderly people were selected. Admissions data were grouped according to socio-environmental profile. Meteorological variables were obtained at IAG/USP and Congonhas airport stations. Air quality data were obtained in Cetesb station. Statistical and numerical modeling tools were used. Statistical correlation between atmospheric variables and hospital admissions was observed, but in different ways. Results: Circulatory (>60 years old): GLM showed increase in hospital admissions with elevation in 1ºC temperature range (0.6per cent) index of pollution (0.2per cent) and decrease in average temperature (0.9per cent). The occurrence of hospitalizations was 12per cent higher with the decrease 1ºC in PET and increase in 1ºC maximum temperature, to lower socio-environmental profile. Respiratory Diseases (>60): GLM indicated increased hospitalizations with the increase in 1ºC in a temperature range (2.1per cent) and pollution (0.2per cent) and decreased 1ºC PET (1per cent). Higher admissions days (3.4per cent) occurred in districts with middle socio-environmental profile with decrease 1ºC minimum temperature. Children: GLM showed an increase in hospital admissions with an increase in average temperature 1°C (3.7per cent), the temperature range (2.7per cent) and pollution (0.2per cent) and a decrease 1ºC of PET (1per cent). Groups of different socio-environmental was significantly associated with thermal comfort index and temperatures range. Conclusions: There were association between morbidity and climatic variables and comfort index in the age groups and diseases. The results partially support the hypothesis that the districts with the worst social and environmental conditions have a higher negative impact on health. The data confirm the proposition with regard to the group of adults over sixty years, but no significant differences for the group of children with respiratory diseases and under-fives (AU)
