Abstract:

We examined the impact of air pollution on hospitalizations for respiratory diseases in total population (DRT), in children under five (DRC) and for cardiovascular diseases in patients over 39 years of age (CVD) in the municipalities of Belo Horizonte, Betim and Contagem, of the Metropolitan Region of Belo Horizonte, Minas Gerais. Generalized additive models using Poisson regression were used to adjust the daily time series of hospitalizations. Single and accumulated lagged pollutants of up to five days were introduced as independent variables and models were adjusted for temperature, humidity, weekdays and holidays. In Belo Horizonte PM10 was related to DRT (RR% 1.06 95% CI: 0.41-1.72); DRC (RR% 1.25 IC95%: 0.25-2.26) and CVD (RR% 2.29, 95% CI: 0.96-3.64). In Betim we observed a RR% 1.33 (95% CI: 0.48-2.18) for DRT and RR% 2.38 (95% CI: 1.20-3.56) for DRC. In Contagem we observed a RR% = 1.23 (95% CI: 0.32-2.15) and RR% = 1.61 (95% CI: 0.26-2.96) for DRT and DRC, respectively. SO2 and CO were also associated with hospitalizations. Respiratory diseases were the outcome most frequently related to air pollutants. These results can be used in discussions of emission control policies in the region.
