Abstract
BACKGROUNDS: Shanghai, in China, is one of the highest incidence cities for asthma morbidity. However, few studies have systemically explored the association of ambient air pollutants and asthma patients with economic costs. OBJECTIVES: The study researched the link of short-term ambient air pollutants exposure and asthma patients in Shanghai. Furthermore, the economic cost was also assessed. METHODS: We applied the generalized addictive model (GAM) to analyze the association between ambient air pollutants and asthma patients with economic costs assessment. RESULTS: We investigated a total of 7200 asthma patient visits (inhabitant in Shanghai). A 10 µg m-3 increase in the current day concentrations of SO2, CO, NO2, PM10, O3 and PM2.5 corresponded to increase of 3.79% [95% CI: 0.84%, 6.83%], 0.27% [95% CI: 0.14%, 0.40%], 0.63% [95% CI: - 0.81%, 2.10%], 1.11% [95% CI: 0.38%, 1.85%], 0.23% [95% CI: 0.31%, 078%] and 1.27% [95% CI: 0.29%, 2.26%] in daily asthma patient visits. In economic cost level, the economic cost of asthma patients were attributed to ambient air pollutants (SO2, CO, NO2, PM10, O3 and PM2.5) with 197 million USD losses per year. Among, the economic cost of asthma patient visits were attributed to SO2, CO, NO2, PM10, O3 and PM2.5 with 101.30, 7.46, 17.15, 30.18, 6.39 and 34.50 million USD loss per year, respectively. CONCLUSIONS: Short-term exposure to SO2, CO, NO2, PM10, O3 and PM2.5 were linked to asthma patient visits increase in Shanghai areas. The economic cost of asthma patient visits were attributed to ambient air pollutants (SO2, CO, O3, PM10, NO2 and PM2.5) with 197 million USD losses per year. The study strengthen our fundamental comprehending of impacts of ambient air pollutants on human health and economy burden.
