“…Many studies have examined health inequalities associated with air pollution, providing evidence that socio‐economic deprivation could exacerbate the adverse health effects of air pollution (Castillo et al., 2021; T. Liu et al., 2021; Martins et al., 2004; Morelli et al., 2016; Wong et al., 2008). Recently, a nationwide study including 2,640 Chinese counties found that people living in counties with lower literacy, college education, GDP per capita, and urbanization levels were more vulnerable to the mortality risks of long‐term PM 2.5 exposure than those living in counties with higher levels of these parameters (L. Han et al., 2021). In addition to the health effects of air pollution, ambient non‐optimal temperatures (both hot and cold temperatures) have also been reported to pose higher risks to populations living in suburban and rural areas than those in urban areas (K. Chen et al., 2016; Hu et al., 2019; Xing et al., 2020), challenging the assumption that populations living in urban areas may bear higher risks of temperature due to urban heat island effects.…”

Between 1978 and 2020, China experienced a rapid increase in the urban population, from 170 to 902 million, corresponding to an urbanization rate change from 17.9% to 63.9% (National Bureau of Statistics of China, 2022). By 2030, the urbanization rate and total urban population in China are projected to reach 71% and 1,070 million, respectively (Q. Chen et al., 2017). This trend can lead to several consequences for the health of China's population. There is no consensus on whether urbanization is more beneficial or detrimental to human health, but the common understanding is that the mechanisms underlying the impact on human health are complex.

“…To examine potential lagged effects of PM 2.5 concentrations, we used the moving average of PM 2.5 in the current year and 1-2 years before (lag 0-1 and lag 0-2) to refit the main model. We applied a meta-regression to check the statistical differences among the effect estimates of the primary model and sensitivity models [30,31]. The effect estimates were modeled against the meta-predictor (e.g.…”

Evidence on the spatial-temporal distribution of TB mortality across China and its relationship with long-term PM2.5 exposure is limited. We aimed to address significant gaps in our understanding of the spatial-temporal clustering patterns of tuberculosis mortality in China and provide evidence for its causal links with long-term PM2.5 exposure. Annual pulmonary tuberculosis mortality, PM2.5 concentrations, and socioeconomic factors for provinces in mainland China between 2004 and 2017 were obtained. Turning points in the temporal trend and spatial clustering patterns of pulmonary tuberculosis mortality were identified. A difference-in-differences causal inference approach was applied to estimate the long-term effect of PM2.5 exposure on the mortality. The average annual percent change of pulmonary tuberculosis mortality in China was -2.5% (95%CI: -5.6%, 0.7%), with an 11.1% annual increase in the Northwest since 2012 (P=0.029). The hot and cold spots were all located in northern China, where Xinjiang in the Northwest had the highest mortality across the study period. We found a significant association between long-term PM2.5 exposure and pulmonary tuberculosis mortality, with percent increases in risks (IR%) being 0.74% (95CI%, 0.04%, 1.45%). This association varied across multiple socioeconomic groups, with the highest IR% in provinces with lower level of latitude (IR%=0.83%, 95%CI: 0.01%, 1.65%), lower quartile of GDP (IR%=1.01%, 95%CI: 0.23%, 1.80%) or higher proportion (≥14%) of people > 65 years of age (IR%=1.24%, 95%CI: 0.44%, 2.04%). Comprehensive sensitivity analyses showed a robust adverse effect of long-term PM2.5 exposure on pulmonary tuberculosis mortality. Attention needs to be paid to the rising trend of pulmonary tuberculosis mortality in Northwest China. Our study provides the stable evidence to date of the causal association between long-term PM2.5 exposure and the risk of death from pulmonary tuberculosis, especially in low-altitude, underdeveloped, and aged provinces.

“…Another explanation considered that social infrastructure and health service were limited, as well as environmental protection sources was not accessible in rural areas. Generally, rural residents conducted more outdoor activities, resulting in higher PM2.5 exposure (Han et al, 2021). They less use anti-PM2.5 air filters and take special face masks to reduce exposure to PM2.5, which increases the exposure risks in rural areas (Zhao et al, 2021).…”

Long-term exposure to PM2.5 pollution is a significant health concern and increases risks for cancers in China. However, the studies regarding the effect of PM2.5 and esophageal cancer incidence (ECI) among urban-rural areas are limited. In this study, we examined the sex-and areaspecific association between long-term exposure to PM2.5 and ECI, as well as explored the corresponding lag effects on ECI using a geographical weighted Poisson regression. We found that each 10 ug/m 3 PM2.5 caused ECI risk increases of 1.22% (95% CI: 1.09%, 1.36%) and 1.90% (95% CI: 1.66%, 2.14%) for males and females after covariates controlled, respectively, during the study period. Moreover, the higher 0.17% and 0.64% incidence risks for males and females in rural areas than urban areas, as well as a larger lag period in rural areas, respectively. In addition, higher risks for both sexes appeared in north, northwestern, and east China. The findings indicated that long-term exposure to PM2.5 was significantly associated with increased risks for ECI, which reinforce a comprehensive understanding for ECI related to PM2.5.
