“…The few existing multi-city studies of the association between ambient PM 2.5 exposure and all-cause hospital admissions obtained estimated risks that tended to be similar to our present findings. A recent study of 24 Canadian cities estimated a 0.29% (95% CI: 0.03–0.56%) increase in all-cause hospital admissions due to ambient PM 2.5 exposure [ 42 ]. A recent study of 200 Chinese cities estimated a 0.20% (95% CI: 0.08–0.31%) increase due to ambient PM 2.5 exposure [ 10 ].…”

The short-term association between ambient particulate matter ≤2.5 microns in diameter (PM2.5) and hospital admissions is not fully understood. Studies of this association with hospital admission costs are also scarce, especially in entire hospitalized populations. We examined the association between ambient PM2.5 and all-cause hospital admissions, the corresponding total charges, and the total charges per patient by analyzing the hospital admission data of 2 years from 628 hospitals in 12 cities in Japan. We used generalized additive models with quasi-Poisson regression for hospital admissions and generalized additive models with log-linear regression for total charges and total charges per patient. We first estimated city-specific results and the combined results by random-effect models. A total of 2,017,750 hospital admissions were identified. A 10 µg/m3 increase in the 2 day moving average was associated with a 0.56% (95% CI: 0.14–0.99%) increase in all-cause hospital admissions and a 1.17% (95% CI: 0.44–1.90%) increase in total charges, and a 10 µg/m3 increase in the prior 2 days was associated with a 0.75% (95% CI: 0.34–1.16%) increase in total charges per patient. Short-term exposure to ambient PM2.5 was associated with increased all-cause hospital admissions, total charges, and total charges per patient.

“…People are becoming more and more interested in the role of sex and gender played in the epidemiology relevant to air pollution. Several recent studies have reported that pollutants have a greater impact on female’s respiratory health than male 47 , 48 . A comprehensive analysis of the relationship between pollutants and death rate found that in a highly polluted environment, the risk for females increased by 1.12% and that for males increased by 0.73% 49 .…”

PM2.5 has an impact on residents' physical health during travelling, especially walking completely exposed to the environment. In order to obtain the specific impact of PM2.5 on walking, 368 healthy volunteers were selected and they were grouped according to gender and age. In the experiment, the heart rate change rate (HR%) is taken as test variable. According to receiver operating characteristic (ROC) curve, the travel is divided into two states: safety and risk. Based on this, a binary logit model considering Body Mass Index (BMI) is established to determine the contribution of PM2.5 concentration and body characteristics to travel risk. The experiment was conducted on Chang'an Middle Road in Xi'an City. The analysis results show that the threshold of HR% for safety and risk ranges from 31.1 to 40.1%, and that of PM2.5 concentration ranges from 81 to 168 μg/m3. The probability of risk rises 5.8% and 11.4%, respectively, for every unit increase in PM2.5 concentration and HR%. Under same conditions, the probability of risk for male is 76.8% of that for female. The probability of risk for youth is 67.5% of that for middle-aged people, and the probability of risk for people with BMI in healthy range is 72.1% of that for non-healthy range. The research evaluates risk characteristics of walking in particular polluted weather, which can improve residents’ health level and provide suggestions for travel decision while walking.

“…Because women may have stronger airway responsiveness, combined with hormones or other factors, and therefore had a stronger physiological response to air pollutants [42,43]. However, there was also con icting research evidence that men were more susceptible to the impact of PM 2.5 on non-accidental mortality [44,45]. In contrast, we found that men were more susceptible to the effects of O 3 on respiratory mortality than women.…”

Background In recent years, air pollution has become an imminent problem in China. Few studies have investigated the impact of air pollution on the mortality of middle-aged and elderly people. Therefore, this study aims to evaluate the impact of PM2.5 and O3 on non-accidental mortality and respiratory mortality of the middle-aged and elderly in Lishui district of China and provide the scientific basis for the prevention and control measures of air pollution. Method: Using daily mortality and atmospheric monitoring data from 2015 to 2019, we applied a generalized additive model with time-series analysis to study the association of PM2.5 and O3 exposure with daily non-accidental mortality and respiratory mortality in Lishui district of China. Using attributable risk to estimate the death burden attributable to short-term exposure to O3 and PM2.5。 Result PM2.5 and O3 were associated with non-accidental and respiratory mortality. For every 10µg/m3 increased in PM2.5, non-accidental mortality increased 0.94% (95%CI: 0.05%-1.83%), and PM2.5 had a more significant impact on women. For every 10µg/m3 increased in O3, respiratory mortality increased 1.35% (95%CI: 0.05%-2.66%). and O3 had a more significant impact on men. Compared with single pollutant model, the impact of the two-pollutant model on non-accidental mortality and respiratory mortality slightly decreased. Besides, in summer and winter, O3 had a more obvious impact on non-accidental mortality. The Population Attributable Fractions of non-accidental mortality were 0.839% (95%CI:0.004–1.626%) for PM2.5 and the PAF of respiratory mortality were 0.135% (95%CI:0.005–0.263%) for O3. Conclusion PM2.5 and O3 could significantly increase the risk of non-accidental and respiratory mortality in middle-aged and elderly people in Lishui district, China. Exposing to air pollutants, men were more susceptible to O3 damage, and women were more susceptible to PM2.5 damage.
