Outdoor Artificial Light at Night and Insomnia-Related Social Media Posts.

Importance: Understanding the outcomes of artificial light at night (ALAN) on insomnia is crucial for public health, particularly in rapidly urbanizing regions. However, evidence of the association between ALAN exposure and insomnia is limited, despite the large number of people exposed to ALAN.

Objective: To explore the association between outdoor ALAN exposure and insomnia among the Chinese population.

Surrounding greenness is associated with lower risk and burden of low birth weight in Iran.

The nexus between prenatal greenspace exposure and low birth weight (LBW) remains largely unstudied in low- and middle-income countries (LMICs). We investigated a nationwide retrospective cohort of 4,021,741 live births (263,728 LBW births) across 31 provinces in Iran during 2013-2018. Greenness exposure during pregnancy was assessed using satellite-based normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI).

Short-term effects of fine particulate matter constituents on myocardial infarction death.

Existing evidence suggested that short-term exposure to fine particulate matter (PM) may increase the risk of death from myocardial infarction (MI), while PM constituents responsible for this association has not been determined. We collected 12,927 MI deaths from 32 counties in southern China during 2011-2013. County-level exposures of ambient PM and its 5 constituents (i.

Submicron particle exposure and stroke hospitalization: An individual-level case-crossover study in Guangzhou, China, 2014-2018.

Background: Short-term exposure to ambient PM and PM (particulate matter with aerodynamic diameters ≤2.5 μm and 10 μm, respectively) has been linked with hospitalization and mortality from stroke. However, the effect of PM (≤1 μm) exposure on the risk of hospitalization from stroke and its subtypes has rarely been investigated, in particular, on the basis of fine-scale exposure assessment at the individual level.

Ambient PM, ozone and mortality in Chinese older adults: A nationwide cohort analysis (2005-2018).

Background: Cohort evidence linking long-term survival with exposure to multiple air pollutants (e.g., fine particulate matter [PM] and ozone) was extensively sparse in low- and middle-income countries, especially among older adults.

Short-term exposure to fine particulate matter constituents and mortality: case-crossover evidence from 32 counties in China.

A growing number of studies associated increased mortality with exposures to specific fine particulate (PM) constituents, while great heterogeneity exists between locations. In China, evidence linking PM constituents and mortality was extensively sparse. This study primarily aimed to quantify short-term associations between PM constituents and non-accidental mortality among the Chinese population.

Early-life exposure to PM constituents and childhood asthma and wheezing: Findings from China, Children, Homes, Health study.

Background: Emerging evidence suggests that early-life (in-utero and first-year since birth) exposure to ambient PM is a risk factor for asthma onset and exacerbation among children, while the hazards caused by PM compositions remain largely unknown.

Objective: To examine potential associations of early-life exposures to PM mass and its major chemical constituents with childhood asthma and wheezing.

Methods: By conducting the Phase II of the China, Children, Homes, Health study, we investigated 30,325 preschool children aged 3-6 years during 2019-2020 in mainland China.

Secular trends in global burden of diabetes attributable to particulate matter pollution from 1990 to 2019.

Increasing evidence suggests an association between fine particulate matter (PM) exposure and type 2 diabetes mellitus. However, there is still a lack of comparative evaluation regarding diabetes burden due to ambient and indoor PM pollution at a global scale. This study attempts to provide a systematic and comprehensive profile for PM-attributable burden of diabetes and its spatiotemporal trends, globally and regionally.

Longitudinal association of egg intake frequency with cardiovascular disease in Chinese adults.

Background And Aims: Reducing dietary cholesterol is generally acceptable for the prevention of cardiovascular disease (CVD). Eggs are nutrient-dense and common food items across the world, while rich in cholesterol. The potential effects of egg intake on cardiovascular health remain uncertainty and have been under debate in past decades.

Reduction in daily ambient PM pollution and potential life gain by attaining WHO air quality guidelines in Tehran.

Background: Fine particulate matter pollution (PM) is widely considered to be a top-ranked risk factor for premature mortality and years of life lost (YLL). However, evidence regarding the effect of daily air quality improvement on life expectancy is scarce, especially in the Middle East such as Iran. This study aimed to investigate the potential benefits in life expectancy at concentrations meeting the daily PM standards during 2012-2016 in Tehran, Iran.
