Design: Prospective cohort study.

Setting: UK Biobank study, 1 January 2006 to 31 December 2010, with follow-up to 31 March 2021 (median follow-up 11.

Re-Imagining Public Health Education: Students' Perspectives and Considerations.

Since the onset of the COVID-19 pandemic, the shortcomings and neglected weaknesses of public health systems have risen to the surface, emphasizing the need for new approaches to designing and delivering public health training. Higher education institutions have a critical role in advocating for societal change and sufficiently prepare the next generations of public health. Therefore, this commentary shares the unique voices of current and recently completed graduate students from public health programs across the United States in identifying areas of improvement, so that proactive steps toward refining the current landscape of public health education and training may be taken.

Histological types of lung cancer attributable to fine particulate, smoking, and genetic susceptibility.

Background: Fine particulate matter (PM), smoking, and genetic factors are associated with lung cancer. However, the relationship between PM, smoking and subtypes of lung cancer remains unclear. Moreover, it is unclear whether genetic risk modifies the impact of PM and smoking on incident lung cancer.

Ambient particulate matter pollution of different sizes associated with recurrent stroke hospitalization in China: A cohort study of 1.07 million stroke patients.

Background: To estimate the associations between ambient particulate matter (PM) pollution of different sizes (PM, PM, and PM) and risk of rehospitalization among stroke patients, as well as the attributable burden in China.

Methods: We built a cohort of 1,066,752 participants with an index stroke hospitalization in Sichuan, China from 2017 to 2019. Seven-day and annual average exposures to PM pollution prior to the date of the index hospitalization were linked with residential address using a bilinear interpolation approach.

Particulate matter pollution and asthma mortality in China: A nationwide time-stratified case-crossover study from 2015 to 2020.

Background: A national and comprehensive evaluation is lacking on the relationship between short-term exposure to submicron particulate matter (PM) pollution and asthma mortality.

Methods: Data was obtained from 29,553 asthma deaths from the China National Mortality Surveillance System from 2015 to 2020. We used a bilinear interpolation approach to estimate each participant's daily ambient particulate matter pollution and meteorological variables exposure based on their geocoded residential address and a 10 km × 10 km grid from China High Air Pollutants and the fifth generation of European ReAnalysis-Land reanalysis data set.

Air quality improvement and cognitive function benefit: Insight from clean air action in China.

Introduction: Epidemiological evidence suggests associations between long-term exposure to air pollution and accelerated cognitive decline. China implemented a strict clean air action plan in 2013; however, it is unclear whether the improvement of air quality has alleviated cognitive impairment in the population.

Methods: From the China Health and Retirement Longitudinal Study, 8536 Chinese adults were enrolled in 2011 and followed up in 2015.

Non-linear Relationship of Maternal Age With Risk of Spontaneous Abortion: A Case-Control Study in the China Birth Cohort.

Background: Spontaneous abortion is one of the prevalent adverse reproductive outcomes, which seriously threatens maternal health around the world.

Objective: The current study is aimed to evaluate the association between maternal age and risk for spontaneous abortion among pregnant women in China.

Methods: This was a case-control study based on the China Birth Cohort, we compared 338 cases ending in spontaneous abortion with 1,352 controls resulting in normal live births.

Ambient gaseous pollutants and emergency ambulance calls for all-cause and cause-specific diseases in China: a multicity time-series study.

Much attention has been paid to the health effects of ambient particulate matter pollution; the effects of gaseous air pollutants have not been well studied. Emergency ambulance calls (EACs) may provide a better indicator of the acute health effects than the widely used health indicators, such as mortality and hospital admission. We estimated the short-term associations between gaseous air pollutants [nitrogen dioxide (NO), sulfur dioxide (SO), and ozone (O)] and EACs for all-cause, cardiovascular, and respiratory diseases in seven Chinese cities from 2014 to 2019.

Constituents of fine particulate matter and asthma in 6 low- and middle-income countries.

Background: Evidence concerning the effects of different chemical components of particulate matter with an aerodynamic diameter of 2.5 μm or less (PM) on asthma is limited, and the methodology to compare the relative importance of different PM components is lacking.

Objective: Our aim was to examine the associations between PM components and asthma and investigate which constituent of PM possessed the most harmful effect on asthma.

The Asthma Family Tree: Evaluating Associations Between Childhood, Parental, and Grandparental Asthma in Seven Chinese Cities.

To evaluate the associations between childhood, parental, and grandparental asthma. We studied 59,484 children randomly selected from 94 kindergartens, elementary, and middle schools in seven Chinese cities from 2012 to 2013, using a cross-sectional survey-based study design. Information on their and their family members' (parents, paternal grandparents, and maternal grandparents) asthma status were reported by children's parents or guardians.

Supporting Caregivers in Pregnancy: A Qualitative Study of Their Activities and Roles.

Background: The significant role of lay caregivers has been explored in chronic and acute illnesses. In pregnancy, caregivers' (eg, the baby's father, friends, and family) roles in promoting the health of the mother and baby are not well understood.

Objective: We characterize the activities and roles of pregnancy caregivers and offer opportunities for engaging this important group.
