Effects of ambient air pollution on cause-specific hospitalizations in Wuhan during 2017-2019.

Background: Few studies have focused on the associations between air pollutants and multiple organ system diseases in the entire hospitalized population. The present study aims to explore the short-term effects of six routinely monitored air pollutants on the broad causes of hospital admissions and estimate the resulting hospital admission burdens.

Methods: Daily hospital admission records from 2017 to 2019 were obtained from the Wuhan Information center of Health and Family Planning.

PM-Associated Hospitalization Risk of Cardiovascular Diseases in Wuhan: Cases Alleviated by Residential Greenness.

PM, a type of particulate matter with an aerodynamic diameter of less than 2.5 μm, is associated with the occurrence of cardiovascular diseases (CVDs), while greenness seems to be associated with better cardiovascular health. We identified 499,336 CVD cases in Wuhan's 74 municipal hospitals between 2017 and 2019.

Association of NO with daily hospital admissions for mental disorders: Investigation of the modification effects of green spaces and long-term NO exposure.

Air pollution is a risk factor for increased hospital admissions due to mental disorders, while green spaces have been linked with better mental health. We linked daily hospital admission records from Wuhan's 74 municipal hospitals from 2017 to 2019 with modeled annual average NO concentrations and added data on the residential surrounding green spaces with 250 m and 500 m buffers based on the normalized difference vegetation index (NDVI) using a land use regression model (LUR). The conditional logistic regression model was used to estimate the acute effect of short-term NO exposure, and stratification analyses were applied to explore the modification effect of long-term NO exposure and green spaces by estimating the odds ratios in the single- and dual-environmental factor groups.

Effects of green spaces on alleviating mortality attributable to PM in China.

Increasing research suggested that green spaces are associated with many health benefits, but evidence for the quantitative relationship between green spaces and mortality attributable to particulate matter with an aerodynamic diameter of 2.5 μm or less (PM) is limited. We collected disease-specific mortality and PM data for a period of 4 years (2015-2018) along with green space data for an 8-year duration (2010-2017) in 31 provincial-level administrative regions of China.

Short-term effects of air pollution on respiratory diseases among young children in Wuhan city, China.

Background: The high risks for childhood respiratory diseases are associated with exposure to ambient air pollution. However, there are few studies that have explored the association between air pollution exposure and respiratory diseases among young children (particularly aged 0-2 years) based on the entire population in a megalopolis.

Methods: Daily hospital admission records were obtained from 54 municipal hospitals in Wuhan city, China.

The Association between Preterm Birth and Ambient Air Pollution Exposure in Shiyan, China, 2015-2017.

Shortening of the gestational duration has been found associated with ambient air pollution exposure. However, the critical exposure windows of ambient air pollution for gestational duration remain inconsistent, and the association between ambient air pollution and early term births (ETB, 37 to 38 weeks) has rarely been studied relative to preterm births (PTB, 28-37 weeks). A time-series study was conducted in Shiyan, a medium-sized city in China.

Effect of ambient fine particulates (PM) on hospital admissions for respiratory and cardiovascular diseases in Wuhan, China.

Background: Positive associations between ambient PM and cardiorespiratory disease have been well demonstrated during the past decade. However, few studies have examined the adverse effects of PM based on an entire population of a megalopolis. In addition, most studies in China have used averaged data, which results in variations between monitoring and personal exposure values, creating an inherent and unavoidable type of measurement error.
