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.

The association between anthropogenic heat and parent-report symptoms of childhood attention deficit hyperactivity disorder in China: A novel perspective reflecting climate change.

Anthropogenic climate change will have a negative impact on worldwide well-being over and above the direct consequences of rising average temperatures. 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.

Exposures to particulate matters and childhood sleep disorders-A large study in three provinces in China.

Objectives: Evidence on the link between long-term ambient particulate matter (PM) exposures and childhood sleep disorders were scarce. 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.

Toxicological evaluation and concentration of airborne PM in high air pollution period in Guangzhou, China.

The emissions and exposure limits for airborne PM are lacking, with limited scientific data for toxicity. 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.

Associations between trace level thallium and multiple health effects in rural areas: Chinese Exposure and Response Mapping Program (CERMP).

Thallium (Tl) is a cumulative high toxicant in the environment, but few studies have investigated the comprehensive health effects underlying chronic Tl exposure at trace levels. This study aims to evaluate the liver, kidney, lung and other potential health effects associated with chronic Tl exposure at trace levels in rural areas of China. Urinary Tl concentrations of 2883 adults from rural areas of 12 provinces in China were measured and 2363 participants were involved in the final analysis.

Winter and spring variation in sources, chemical components and toxicological responses of urban air particulate matter samples in Guangzhou, China.

The sources and chemical components of urban air particles exhibit seasonal variations that may affect their hazardousness to human health. Our aims were to investigate winter and spring variation in particulate matter (PM) sources, components and toxicological responses of different PM size fractions from samples collected in Guangzhou, China. Four size-segregated PM samples (PM, PM, PM, and PM) were collected separately during winter (December 2017 and January 2018) and spring (March 2018).

Fine and ultrafine airborne PM influence inflammation response of young adults and toxicological responses in vitro.

Little evidence is available regarding the impact of different sizes of inhaled particulate matter (PM) on inflammatory responses in healthy young adults in connection with toxicological responses. We conducted a five-time repeated measurement panel study on 88 healthy young college students in Guangzhou, China from December 2017 to January 2018. Blood samples were collected from each participant and tested for tumor necrosis factor alpha (TNF-α) levels every week for 5 consecutive weeks.

Outdoor light at night, overweight, and obesity in school-aged children and adolescents.

Previous studies have indicated that outdoor light at night (LAN) is associated with a higher prevalence of overweight or obesity in adults. However, the association of LAN levels with overweight or obesity in children is still unknown. This study utilized data from the Seven Northeastern Cities study, which included 47,990 school-aged children and adolescents (ages 6-18 years).

Long-term PM exposure and human blood lipid metabolism: New insight from the 33-community study in China.

Ambient particles with aerodynamic diameter <0.1 μm (PM) have been suggested to have significant health impact. However, studies on the association between long-term PM exposure and human blood lipid metabolism are still limited.

Exposure to second-hand smoke during early life and subsequent sleep problems in children: a population-based cross-sectional study.

Background: Previous studies have revealed that current secondhand smoke exposure showed highly suggestive evidence for increased risk of simultaneous sleep problems in children. Data on the associations between early-life exposure to SHS with subsequent sleep problems in children were scarce. We aimed to evaluate the associations of early-life SHS exposure with sleep problems in children.

Is greener better? Associations between greenness and birth outcomes in both urban and non-urban settings.

Background: Beneficial effects of greenness on birth outcomes have been reported, but few studies have investigated the associations in both urban and non-urban settings. We aimed to evaluate and compare linear and nonlinear associations between greenness and birth outcomes in urban and non-urban settings.

Methods: From October 2015 to December 2018, participants were recruited into the Maoming Birth Cohort Study.

Street view greenness is associated with lower risk of obesity in adults: Findings from the 33 Chinese community health study.

Background: Urban greenness may protect against obesity, but very few studies have assessed 'street view' (SV) greenness metrics, which may better capture people's actual exposure to greenness compared to commonly-used satellite-derived metrics. We aimed to investigate these associations further in a Chinese adult study.

Methods: Our analysis included 24,845 adults in the 33 Chinese Community Health Study in 2009.

Short-Term Effects of Particle Sizes and Constituents on Blood Biomarkers among Healthy Young Adults in Guangzhou, China.

Evidence of the effects of various particle sizes and constituents on blood biomarkers is limited. We performed a panel study with five repeated measurements in 88 healthy college students in Guangzhou, China between December 2017 and January 2018. Mass concentrations of particles with aerodynamic diameters ≤ 2.

Associations of Particulate Matter Sizes and Chemical Constituents with Blood Lipids: A Panel Study in Guangzhou, China.
