There is a lack of evidence regarding associations of eye-level greenness exposure with blood pressure among children. We aimed to investigate the associations between different types of eye-level greenness and pediatric blood pressure in China. From 2012 to 2013, we recruited 9354 children aged between 5 and 17 years in northeast China.

But anthropogenic heat (AH) relationship with childhood attention deficit hyperactivity disorder (ADHD) is unknown. To assess the relationship with AH exposure and childhood ADHD symptoms in the context of global climate change, this study was conducted in a cross-sectional survey from April 2012 to May 2018 in the northeastern, northwestern, and southern regions of China, with a total enrollment of 179,846 children aged 6-18 years.

However, the health risk assessment of chlorinated paraffins (CPs), an emerging pollutant occupying a high proportion of persistent organic pollutants (POPs) in PM, remains scarce. This study aimed to evaluate the association between PM-bound CPs and asthma, along with relative symptoms, in school-aged children and adolescents.

We did a population-based cross-sectional survey, including 177,888 children from 173 primary and middle schools in 14 Chinese cities. A satellite-based spatiotemporal model was employed to assess four-year average O exposure at both residential and school locations.

This study explores the individual and joint associations between PM constituents and CER hospitalization risks through a cohort analysis of 36,271 adults in the Pearl River Delta, South China, from 2015 to 2020. Cox proportional hazards regression and quantile-based g-computation models were used to quantify the individual and joint associations of annual mean concentrations of PM constituents with hospitalization for CERs.

This study aims to examine the associations between long-term exposure to O and sleep disorders in children. We conducted a population-based cross-sectional survey, including 185,428 children aged 6-18 years in 173 schools across 14 Chinese cities during 2012 and 2018.

We examined the associations between long-term exposures to PM and PM (PM with an aerodynamic equivalent diameter <2.5 μm and <1 μm, respectively) with sleep disorders in children.

Therefore, we continuously monitored and calculated the number and mass concentrations of airborne PM in December 2017, January 2018 and March 2018 during the high pollution period in Guangzhou. We collected PM from the same period and analyzed their chemical components.

Moreover, the effect of the combined exposure to PFASs and their alternatives on uric acid has not been reported. Hence, we conducted a cross-sectional study involving 1312 adults in Guangzhou, China.

Objectives: To evaluate associations between SHS exposure and NDDs diagnosis, identify critical time windows, and summarize the strength of evidence.
Information on the spatio-temporal patterns of the burden of ischemic heart disease (IHD) caused by ambient ambient fine particulate matter (PM) in the global level is needed to prioritize the control of ambient air pollution and prevent the burden of IHD. The Global Burden of Disease Study (GBD) 2019 provides data on IHD attributable to ambient PM. The IHD burden and mortality attributable to ambient PM were analyzed by year, age, gender, socio-demographic index (SDI) level, geographical region and country.

A total of 101 participants were recruited from a cohort in Shijiazhuang, Hebei province, China. They underwent baseline and follow-up surveys in 2011 and 2015.

In this study, we matched the 2008-2012 average anthropogenic heat flux, as simulated by a grid estimation model using inventory methods, with questionnaire and measurement data of 49,938 children randomly recruited from seven cities in Northeast China in 2012. After adjusting for social demographic and behavioral factors, we used generalized linear mixed-effect models to assess the association between anthropogenic heat flux and adiposity among children.

We examined the potential association between the quality of migrant patients' PHC experiences and the achievement of Patient-Centered Medical Home by CHCs in China.
Methods: Between August 2019 and September 2021, 482 migrant patients were recruited from ten CHCs in China's Greater Bay Area.
Chlorinated paraffins (CPs) belong to an emerging class of persistent organic pollutants (POPs) widely detected in environmental matrices and human samples. The potential health risks of CPs on humans have initiated intense concerns but there have been few studies focusing on the said topic. Addressing the gap, we make a scoping review on the current global body of evidence from epidemiological and toxicological studies.
