Effects Of Environmental Factors And Atmospheric Pollution In The Incidence Of Hospital Admissions By Stroke In São Paulo City

Abstract Objectives: To analyze the association between ambient temperature, air humidity and atmospheric pollution with the incidence of hospital admissions for stroke in the city of São Paulo in 2016. Results: An average in the year 2016 was observed for CO of 0.58 ppm (SD = 0.12), not exceeding 0.81 ppm. For MP10, there was an annual average of 28, 26 μg / m3 (SD = 7.13), ranging from 20, 45 μg / m3 to 42.81 μg / m3. MP2.5 had a mean of 2016 of 13.40 μg / m3 (SD = 5.01). SO2 had an annual average of 1,90 μg / m3 (SD = 0,90), with a minimum of 1,20 μg / m3 and a maximum of 4,20 μg / m3. It is observed that the higher incidence values of stroke were stated in the colder and drier months at the year between May and August, that is evident looking for the female incidence of 769 in August and the male incidence of 8.92 in July. This fact matches with high concentrations of the pollutants, mostly SO2 that had the most relevant value of 4.2 μg / m3 in July.
