Background: Greenspace is an important modifiable environmental factor that is associated with health and well-being. Although previous research has shown that exposure to greenspace is beneficial for cardiovascular diseases, studies have rarely focused on early subclinical health outcomes such as electrocardiogram (ECG) abnormality.
Methods: We developed a longitudinal study using data from the China National Stroke Screening Survey (2013-2019).
Whether maternal exposure to dust-sourced particulate matter (hereafter, dust PM) is associated with stillbirth remains unknown. We adopted a sibling-matched case-control design to analyze 9332 stillbirths and 17,421 live births. We associated the risk of stillbirth simultaneously with dust and nondust components of PM and developed a nonlinear joint exposure-response function.

However, evidence on the long-term health effects of floods from large-scale studies on the vulnerable aged population in China is insufficient. This study analyzed the long-term effects of exposure to flood on electrocardiographic (ECG) abnormalities, a commonly used indicator of cardiovascular disease (CVD) screening, in middle-aged and elderly people.

While temperature fluctuation has been demonstrated to be a risk factor for cardiovascular diseases, few epidemiological studies have reported its relationship with ECG outcomes. In this study, we employed temperature anomaly (TA) as an innovative indicator of temperature fluctuation to quantify its detrimental impacts on ECG outcomes.

Methods: Derived from the national community-based China Hypertension Survey database during 2012--2015, a total of 203 108 residents aged at least 18 years were included. Individual-level physical activity was evaluated using a standardized questionnaire, and minutes of metabolic equivalent tasks per week (MET-min/week) were calculated, integrating domain, intensity, frequency, and duration.
Stroke is a significant global cause of disability and death, and its burden has been on the rise, while ambient air pollution has been conclusively linked to stroke incidence. However, knowledge about effects of atmospheric oxidation on stroke and its interactions with fine particles (PM) are still limited. In this study, we investigated the short-term effects of ambient NO, O, and their combined oxidation (O) on first-ever stroke, based on data from the China National Stroke Screening Survey (CNSSS) conducted from 2013 to 2015.

Background: Recently, professionals, such as those from the World Health Organization, have recommended a rigorous standard for nitrogen dioxide (NO), a typical urban air pollutant affected by regular traffic emissions, based on its short-term and long-term cardiorespiratory effects. However, the association between middle-term NO exposure and cardiovascular disorders remains unknown.
Objectives: This study was conducted to examine the relationship between NO exposure and its middle-term cardiovascular risks indicated by electrocardiogram (ECG) abnormalities.
Background: Long-term exposure to ambient fine particulate matter (PM) has been linked to an increased risk of stroke. However, the effect of long-term exposure to PM and its major components on the functional disability of stroke patients remains unclear.
Methods: Based on China National Stroke Screening Survey data obtained from 2013 to 2019, we conducted a national multicenter longitudinal study of the associations of long-term exposure to PM and its components with the risk of disability after stroke in China.
Ambient ozone (O) pollution has been associated with an increased risk of cardiovascular diseases. However, few studies have addressed the effect of O exposure on electrocardiogram (ECG) abnormalities, a subclinical indicator of early damage to the cardiovascular system. This study aimed to examine the association between short-term exposure to O and ECG abnormalities.

The trade-off between harmful effects of PM exposure and protective effects of PA remain unclear. Our study aims to examine the joint effects of PA and PM exposure on blood pressure (BP) in Chinese adults.
View Article and Find Full Text PDFBackground: Electrocardiogram (ECG) abnormalities are known to have prognostic value for heart conditions, while evidence on the relationship between long-term exposure to PM constituents and electrocardiographic (ECG) abnormalities is limited. This study aimed to quantify the association between long-term exposure to PM constituents and changes in ECG diagnoses.
Methods: We designed a longitudinal study among participants with repeated records of ECG examination based on the China National Stroke Screening Survey 2013-2018.
Due to global warming, an increased number of open fires is becoming a major contributor to PM pollution and thus a threat to public health. However, the burden of stillbirths attributable to fire-sourced PM is unknown. In low- and middle-income countries (LMICs), there is a co-occurrence of high baseline stillbirth rates and frequent firestorms, which may lead to a geographic disparity.

Gestational exposure to ambient fine particles (PM) increases the risk of stillbirth, but the related disease burden is unknown, particularly in low- and middle-income countries (LMICs). We combine state-of-the-art estimates on stillbirths, and multiple exposure-response functions obtained from previous meta-analyses or derived by a self-matched case-control study in 54 LMICs. 13,870 stillbirths and 32,449 livebirths are extracted from 113 geocoded surveys from the Demographic and Health Surveys.

Background: Gestational hypertension (GH), preeclampsia (PE), and gestational diabetes mellitus (GDM) are common pregnancy complications and can result in maternal and prenatal morbidity and mortality. Air pollution exposure could adversely impact pregnancy complications; however, evidence remains limited in China, where ambient air pollution is relatively severe.
Objective: This study aims to examine the associations of GH, PE, and GDM with exposure to six air pollutants (PM PM, SO, NO, O, and CO) during pregnancy.
Background: Exposure to landscape fire smoke (LFS) is linked to child mortality and birthweight. It is unknown whether gestational exposure to LFS affects child survival rate. We aimed to link under-five death (U5D) to gestational LFS exposure by performing a causal mediation analysis based on birthweight.
