RESUMO

The constant exposition to air pollution continues to cause the populations health problems, and its result an increase of morbidity and mortality by respiratory and cardiovascular diseases. This is a cross-sectional study which aims to assess the modifications in the systemic blood pressure and the pulse pressure in young male individuals, exposed to the traffic pollution in Santo André city, metropolitan region of the Greater São Paulo in Brazil. The hourly daily levels of air pollutants were obtained from the Technology Institute for the Environment and Sanitation of São Paulo State (CETESB), the information by temperature and precipitation was obtained from the National Meteorology Office (INMET). There has been carried out a descriptive analysis of all variables of the study. The linear equation model has been used, having as dependent variables the systolic blood pressure (SBP), the diastolic blood pressure (DBP) and the pulse pressure (PP), the air pollutants as independent variables, and as control variables the minimum temperature, precipitation, working period and day time. A number of 19 traffic agents in Santo André city have been analysed. The average age of the studied group was of 42.8 (sd = 5.2) years old, ranging from 32 to 51 years old. Concerning the BMI, we have got the information that the average of the studied group was of 25.2 (sd = 2.8), ranging from 19.2 to 29.4. It is observed that for an interquartile range increased in PM10 (34g/m3), the SBP increases in 1.35 mmHg (CI95%: 0.40; 2.30), the DBP increases in 1.35 mmHg (CI95%: 0.57; 2.13), and the PP increases in 1.35 mmHg (CI95%: 0.40; 2.30) at the exposure time. The traffic agents in Santo André city presented increase of SBP, DBP and PP with the exposure to PM10 and to O3. The traffic agents from Santo André presented higher arterial blood pressure and pulse pressure levels associated with the air pollution exposure in Santo André city
