Impacts of PM10 exposure on hospitalization for acute bronchitis in Ankara, Türkiye

Abstract

The purpose of this study is to investigate the relationship between PM10 exposure and acute bronchitis admissions in Ankara, Türkiye. PM10 data and daily acute bronchitis admissions were obtained in Ankara for 2020-2021. A generalized additive model was applied to estimate the effects of daily PM10 concentration on hospital admissions for acute bronchitis. The Distributed Lag Non-linear Model was utilized to evaluate the lagged effects of PM10 concentration. Additionally, the model was adjusted for stratified analyses according to gender and age groups. Relative risks with corresponding 95% confidence intervals (CIs) were obtained for each 10 μg/m3 increment in PM10 values. A rise of 10 μg/m3 in PM10 concentrations was significantly linked with an elevated risk of acute bronchitis with relative risks observed at lag3 (RR: 1.010, 95% CI: 1.001-1.019) and lag4 (RR: 1.010, 95% CI: 1.002-1.019). There were associations for middle-aged individuals (45 to 64 years), with a 0.5% increase in risk at lag3 (RR: 1.005; 95% CI: 1.001-1.009) and lag4 (RR: 1.005; 95% CI: 1.001-1.010). PM10 exposure could increase the risk of acute bronchitis and better air quality would be beneficial to human health.
