The Relationship

Abstract Background The effect of ambient temperature on allergic rhinitis (AR) remains unclear. Accordingly, this study aimed to explore the relationship between ambient temperature and the risk of AR outpatients in Xinxiang, China. Method Daily data of outpatients for AR, meteorological conditions, and ambient air pollution in Xinxiang, China were collected from 2015 to 2018. The lag-exposure-response relationship between daily mean temperature and the number of hospital outpatient visits for AR was analyzed by distributed lag non-linear model (DLNM). Humidity, long-time trends, day of the week, public holidays, and air pollutants including sulfur dioxide (SO2), and nitrogen dioxide (NO2) were controlled as covariates simultaneously. Results A total of 14,965 AR outpatient records were collected. The relationship between ambient temperature and AR outpatients was generally M-shaped. There was a higher risk of AR outpatient when the temperature was 1.6–9.3 °C, at a lag of 0–7 days. Additionally, the positive association became significant when the temperature rose to 23.5–28.5 °C, at lag 0–3 days. The effects were strongest at the 25th (7 °C) percentile, at lag of 0–7 days (RR: 1.32, 95% confidence intervals (CI): 1.05–1.67), and at the 75th (25 °C) percentile at a lag of 0–3 days (RR: 1.15, 95% CI: 1.02–1.29), respectively. Furthermore, men were more sensitive to temperature changes than women, and the younger groups appeared to be more influenced. Conclusions Both mild cold and mild hot temperatures may significantly increase the risk of AR outpatients in Xinxiang, China. These findings could have important public health implications for the occurrence and prevention of AR.

Abstract Background Few studies have explored the modifications by family stress and male gender in the relationship between early exposure to traffic-related air pollution (TRAP) and allergic rhinitis (AR) risk in preschool children. Methods We conducted a case-control study of 388 children aged 2–4 years in Shenyang, China. These children AR were diagnosed by clinicians. By using measured concentrations from monitoring stations, we estimated the exposures of particulate matter less than 10 μm in diameter (PM10), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), and sulfur dioxide (SO2) in preschool children aged 2–4 years. After adjusted potential confounding factors, we used logistic regression model to evaluate the odds ratio (OR) and 95% confidence interval (CI) for childhood AR with exposure to different air pollutants according to the increasing of the interquartile range (IQR) in the exposure level. Results The prevalence of AR in children aged 2–4 years (6.4%) was related to early TRAP exposure. With an IQR (20 μg/m3) increase in PM10 levels, an adjusted OR was significantly elevated by 1.70 (95% CI, 1.19 to 2.66). Also, with an IQR (18 μg/m3) increase in NO2, an elevated adjusted OR was 1.85 (95% CI, 1.52 to 3.18). Among children with family stress and boys, PM10 and NO2 were positively related to AR symptoms. No significant association was found among children without family stress and girls. Conclusions Family stress and male gender may increase the risk of AR in preschool children with early exposure to PM10 and NO2.

The Impact

Objectives to reveal cause-and-effect relationships in the system "air pollution morbidity of the population" in a large industrial city. Material and methods.The dynamics of the pollutants concentration, such as formaldehyde and benzopyrene, through the period of 20152017 was analyzed in relation to the indicators of the morbidity of the respiratory system in the population of Samara. In particular, the study focused on the ratio of allergic rhinitis and asthma cases and the concentration of the formaldehyde and benzopyrene. Results.The incidence of respiratory diseases and the general morbidity increased both among children (by 46.7%) and adults (by 11.4%). There was the causal correlation between the effect of benzopyrene on the development of allergic rhinitis and bronchial asthma in children(r = 0.57 and r = 0.76) and in adults (r = 0.45 and r = 0.51) in Samara. The significant differences between the level of the pollutants and the frequency of the respiratory system diseases were registered in children and adults in different areas of Samara. Discussion.As a result of the increase of the maximum allowable concentration (MAC) of formaldehyde in atmospheric air, this pollutant has now ceased to be a priority. The revealed negative correlations point to the absence of an adverse effect of formaldehyde on the development of allergic rhinitis and bronchial asthma in both children and adults in Samara. Conclusion.According to the results of the study, the preventive measures aimed at reducing the impact of main air pollutants on the health of children and adults in Samara were suggested. Their implementation is possible by the immediate informing of the executive authorities to ensure they can make timely management decisions to improve the quality of the environment.
