“…In addition, Dehghan et al reported that the effect of NO 2 and PM 2.5 were stronger among women (Dehghan et al 2018). Chen et al (2019) found that men are more susceptible to PM 2.5 DECH than women in the case of cardiovascular mortality (D. Chen et al 2019). Similar to this, in our study, significant associations found between NO 2 and IHD mortality in men were stronger than those in women.…”

“…PM 10 and PM 2.5 had stronger effect in age > 60 years than age < 60 years (Dehghan et al 2018). However, a study in Tehran indicated that 0-64 years old people suffered more from PM 2.5 pollution than people at older ages (D. Chen et al 2019). In a study conducted in Ahvaz, people aged over 60 years were more affected by NO 2 and CO than those in younger ages (Dastoorpoor et al 2018b).…”

“…Therefore, PM 2.5 daily excessive concentration hours (PM 2.5 DECH) has been introduced as an alternative (Lin et al 2017). In a study in Tehran (Iran), an interquartile range (IQR) increase in PM 2.5 DECH was related to 2.26% (95% CI 0.85, 3.69%) increase in cardiovascular diseases (D. Chen et al 2019).…”

This study investigated the association of short-term exposure to PM 10 , PM 2.5 , NO 2 , O 3 , and CO with daily all-cause, cardiovascular, ischemic heart disease (IHD), cerebrovascular, and respiratory deaths in Mashhad, a tourist megacity in Iran (2014Iran ( -2018. A distributed-lag-day, nonlinear model (DLNM) and generalized additive model (GAM) based on the quasi-Poisson distribution were used to explore the exposure-lag-day-response associations. The average (± standard deviation) concentrations of PM 10 , PM 2.5 , NO 2 , O 3 , and CO were 67.1 (± 35.5), 29.6 (± 14.2), 57.3 (± 24.1), 55.9 (± 16.9), and 1907.6 (± 1362.7) μg/m 3 , respectively. NO 2 was associated with IHD mortality in lag-days 0 to 0-7, and lag-day 1. The relative risks (RRs) for a 10 μg/m 3 increase in NO 2 ranged from 1.01 (95% CI 0.93, 1.11) at lag-day 0 to 1.04 (95% CI 0.94, 1.16) and 1.03 (95% CI 0.93, 1.14) for lag-day 0-1 (cumulative) and lag-day 1 (non-cumulative), respectively. For all-cause mortality, cumulative exposure to PM 2.5 for lag-day 0-7 (1.07, 95% CI 1.00, 1.15) and non-cumulative exposure to NO 2 at lag-day 6 (1.02, 95% CI 1.00, 1.03) were significant. Exposure to PM 10 (per 10 μg/m 3 ) was significantly associated with respiratory mortality at several lag-days. Adjusting for Ramadan did not significantly affect the results. PM 10 had significant associations with respiratory mortality of people > 65 years old, and men for several lag-days. For IHD, NO 2 affected older people, and men and women over different lagdays. Results of multi-pollutant models were similar to the single-pollutant model outcomes. In conclusion, NO 2 and PM 10 had more significant relationships with adverse health outcomes than the other pollutants.

“…To our knowledge, few studies have been conducted to evaluate the effects of short-term exposure to air pollution on cause-specific YLL in other countries than China. A recent study in Tehran focused on the effects of short-term exposure to PM 2.5 on CVD-specific YLL and found that an interquartile range increase in daily average concentration of PM 2.5 was associated with 35.21 (95% CI: 10.85–59.58) years increase in CVD-specific YLL [ 72 ]. However, in subgroup studies (including gender and age), opposite trends were found when compared with our study.…”

(1) Background: Years of life lost (YLL) as a surrogate of health is important for supporting ambient air pollution related policy decisions. However, there has been little comprehensive evaluation of the short-term impact of air pollution on cause-specific YLL, especially in China. Hence in this study, we selected China as sentinel region in order to conduct a meta-analysis to evaluate disease-specific YLL due to all the main ambient air pollutants. (2) Methods: A meta-analysis was conducted to evaluate disease-specific YLL due to the main ambient air pollutants in China, and 19 studies were included. We conducted methodological quality and risk of bias assessment for each included study as well as for heterogeneity and publication bias. Subgroup analysis and sensitivity analysis were also performed. (3) Results: Meta-analysis indicated that increases in PM2.5, PM10, SO2 and NO2 were associated with 1.99–5.84 years increase in YLL from non-accidental diseases. The increase in YLL to cardiovascular disease (CVD) was associated with PM10 and NO2, and the increase in YLL to respiratory diseases (RD) was associated with PM10. (4) Conclusions: Ambient air pollution was observed to be associated with several cause-specific YLL, increasing especially for elderly people and females.

“…NCDs accounted for 82% of all deaths in 2018 in Iran [22]. A study conducted in Tehran demonstrated the CVD mortality burden is associated with air pollution [23]. It is estimated that 79, 200 and 9100 deaths per year are the results of environmental factors and potential outcomes of outdoor air pollution respectively [24].…”

Background Ensuring public health is crucial in any policy debate on climate change. Paris Agreement on climate change is a global contract, through which countries have committed themselves to a public health treaty. The agreement has laid the foundation for mitigation and adaptation. This study was conducted to provide an evidence-based framework for policy-making in the health system of Iran in order to reduce the adverse effects of climate change on public health and to increase the adaptation of the health system as a result. Methods This is a qualitative study. We first used Delphi method to extract the components of Paris Agreement on climate change that were related to the functions and policymaking of health system in Iran. Twenty-three experts in health and climate change were identified purposefully and through snowball sampling as participants in Delphi. Data collection instrument was a structured questionnaire. We used SPSS software version 25 for data analysis based on the descriptive indices including the mean, the percentage of consensus above 75%, and the Kendall coordination coefficient. Results Seventy-nine components classified within nine categories were extracted. The most important examples of the implementation of Paris Agreement on climate change in the health system of Iran were: participation in the formulation of strategies for mitigation and adaptation, identifying vulnerable groups, assessing vulnerability, increasing the capacity of health services delivery during extreme events, using early warning systems, using new technologies to increase the adaptation, evaluation of interventions, financial support, increasing the number of researches, increasing the knowledge and skills of staff, and finally public awareness. Conclusions Evidence-based policy-making is pivotal to develop effective programs to control the health effects of climate change. This research provided policy translation and customization of micro and macro provisions of Paris Agreement on climate change, in line with the political context of health system in Iran. Our finding will pave the ground, we envisage, for further steps towards capacity building and enhancement of resiliency of the health system, adaptation interventions, and evaluation, identification of barriers and facilitators for adaptation and decreasing the adverse health effects caused by the climate change, in Iran and perhaps beyond.
