0177/2018 - Poluição do ar e impactos na saúde na Região Metropolitana de Belo Horizonte – Minas Gerais. Air pollution and health impacts in the Metropolitan Region of Belo Horizonte - Minas Gerais.
Examinamos o impacto da poluição atmosférica nas internações por doenças respiratórias totais (DRT), em crianças menores de cinco anos (DRC) e por doenças cardiovasculares em maiores de 39 anos (DCV) nos municípios de Belo Horizonte (BH), Betim e Contagem, da Região Metropolitana de Belo Horizonte. Modelos aditivos generalizados via regressão de Poisson foram utilizados para ajustar as séries de hospitalizações. Os poluentes em defasagem simples e acumulada de até cinco dias foram introduzidos como variáveis independentes e os modelos foram ajustados para temperatura, humidade, dias da semana e feriados. Em BH o PM10 esteve relacionado as DRT (RR% 1,06 IC95%:0,41-1,72); DRC (RR% 1,25 IC95%:0,25-2,26) e DCV (RR% 2,29 IC95%:0,96-3,64). Em Betim observou-se RR% 1,33 (IC95%:0,48-2,18) para DRT e RR% 2,38 (IC95%:1,20-3,56) para DRC. Em Contagem observou-se RR% 1,23 (IC95%:0,32-2,15) e RR% 1,61 (IC95%:0,26-2,96) para DRT e DRC respectivamente. SO2 e CO também apresentaram associação com as hospitalizações. As doenças respiratórias foram o desfecho mais relacionado aos poluentes investigados. Esses resultados podem ser úteis nas discussões das políticas de controle de emissões na região.

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.
