Abstract Background Inter-mortality displacement (IMD) between cause-specific mortalities has not been introduced in air pollution epidemiology. Investigation into IMD would provide insights on the actual health burden of air pollution and interpretation of associations. We aimed to investigate IMD regarding short-term effect of air pollution on mortality. Methods We illustrated manifestations and interpretations of lag-mortality associations. If IMD exists, a net increase of one cause-specific death can be offset by a net decrease of other cause-specific deaths. We conducted a time-series analysis to estimate associations of ambient particulate matter smaller than 10 µm (PM10), ozone (O3), sulphur dioxide (SO2), nitrogen dioxide (NO2) and carbon monoxide (CO) with mortality, considering lags up to the previous 45 days, for seven major cities of South Korea from 2006 to 2013. Attributable mortality cases were identified. Results For O3, respiratory mortality [11 929 cases, 95% empirical confidence interval (eCI), 5358, 17 688 cases] was counterbalanced by cardiovascular mortality (-11 272 cases, 95% eCI: -22 444, -629 cases). All-cause mortality was 37 148 cases (95% eCI: 4448, 68 782 cases). For PM10, respiratory deaths were 9167 cases (95% eCI: 563, 16 521 cases), and cardiovascular deaths were 6929 cases (95% eCI: -11 793, 24 138 cases). Estimates for SO2 were comparable to those for PM10. All-cause mortality attributable to NO2 was explained by short-term mortality displacement. No associations with mortality were found for CO. Conclusions IMD may exist in the relationship between air pollution and mortality. The actual relationship between air pollution and cause-specific mortality may be masked by IMD.

Abstract Background Although time-series studies of the impact of air pollution on mortality are numerous in the literature there is noticeable lack of the results from multi-city studies in Poland. The aim of our analysis is to fill this gap and give estimates based on the most actual data. Methods A multi-city ecological time series analysis was carried out. A database contained a daily number of deaths from all causes (excluding external), by sex and age groups (below 65, 65 and more), PM10 and PM2.5 levels as well as meteorological conditions in 3 agglomerations and 19 big cities in Poland. The analysis was performed using generalized additive models. The distributed lag model method was used to investigate the mortality displacement phenomenon. Results Two versions of time-series analysis considering the level of air pollution from the current and previous day (acute effect) as well as from the past 30 days (allowing for mortality displacement) in the total population as well as in sub-populations determined by sex and age-group were done in each localization. The pooled effect estimate was calculated based on estimates obtained in each city. The value of the relative risk of death from all causes associated with an increase of air pollution with PM10 and PM2.5 was equal to (respectively) 1.005 (1.003-1.006) and 1.004 (1.002-1.005) for acute effect and 1.016 (1.011-1.021) and 1.021 (1.015-1.026) for delayed pollution effect. Higher relative risks were obtained for females and in the older age group. Conclusions A statistically significant short-term effect of air pollution with both PM10 and PM2.5 on mortality was found. The relative risks for PM2.5 were higher than for PM10. Population of females and people aged 65 years and above were more at risk. Key messages The existence of the short-term effect of dust air pollution on mortality in Poland has been confirmed. The air pollution effect modification by sex and age was found.

Abstract Funding Acknowledgements Type of funding sources: None. Background The short-term effect of air pollution on cardiovascular mortality is well-documented but a scarce number of studies focus on cause-specific mortality in low-polluted areas. Purpose We decided to distinguish deaths due to cerebrovascular disease (CbVD) from a region widely known as the Green Lungs of Poland to assess the short-term effect of air pollution on CbVD mortality. Methods The analysis with almost 4,500,000 person-years of follow-up with a time-stratified case-crossover design was performed. Results are reported as odds ratio (OR) associated with an increase in interquartile range (IQR) of air pollution. Results In the overall analysis of the studied region PM2.5 had an impact on increased CbVD mortality at LAG 0 (OR 1.046, 95% CI 1.013 – 1.080, P = 0.006), LAG 0-1 (1.048, 1.002-1.082, P = 0.040), and LAG 0-3 (1.052, 1.015-1.090, P = 0.006). The influence of PM10 was noted at LAG 0 (1.041, 1.002-1.082, P = 0.040). CbVD mortality in Bialystok was increased by exposure to PM10 at LAG 0 (1.05, 1.00-1.09, P = 0.048) and CO at LAG 1 (1.07, 1.00-1.14, P = 0.04). Additionally, an effect of CO was observed in cold season at LAG 1 (1.09, 1.02-1.17, P = 0.02), LAG 0-1 (1.08, 1.00-1.016, P = 0.04), and LAG 0-3 (1.09, 1.01-1.18, P = 0.04). In Suwalki, an impact of PM2.5 was also observed. Conclusions A short-term increase in air pollutants concentrations, especially in PM2.5 and CO, had an influence on CbVD mortality. Mortality rates were significantly increased in cold season. We also found heterogeneity in the influence of major contributors on mortality between analyzed cities.
