Multiple variable logistic regression analysis was conducted to examine the associations between OEB and the diseases.

Dredging the Charge-Carrier Transfer Pathway for Efficient Low-Dimensional Ruddlesden-Popper Perovskite Solar Cells.

Low-dimensional Ruddlesden-Popper (LDRP) perovskites still suffer from inferior carrier transport properties. Here, we demonstrate that efficient exciton dissociation and charge transfer can be achieved in LDRP perovskite by introducing γ-aminobutyric acid (GABA) as a spacer. The hydrogen bonding links adjacent spacing sheets in (GABA) MA Pb I (MA=CH NH ), leading to the charges localized in the van der Waals gap, thereby constructing "charged-bridge" for charge transfer through the spacing region.

The effect of health literacy on COVID-19 vaccine hesitancy among community population in China: The moderating role of stress.

Background: The public's hesitant attitude is a major subjective barrier in promoting vaccination against COVID-19 to build herd immunity. The current study aimed to address how individual factors such as health literacy and perceived stress affect people's vaccine hesitancy of COVID-19 vaccine, and to provide insights for tailoring vaccine-promotion strategies.

Methods: With structured questionnaires, an online survey was conducted to address the relationship between the health literacy, perceived stress, and COVID-19 vaccine hesitancy among community population in mainland, China.

Association of Excessive Use with Mental Disorders: A Representative Nationwide Study in China.

Objectives: We examined associations between excessive use and mental disorders at the individual and contextual level.

Methods: We conducted a representative nationwide survey sampling process of 11,283 medical students from 30 universities in China. Mental health status was measured by the Chinese Health Questionnaire.

Urban Air Pollution and Mental Stress: A Nationwide Study of University Students in China.

Studies exploring the relationship between air pollution levels and mental stress have rarely been done, and no studies have been done comparing university student mental stress levels based on regional air pollution levels. The objective of this study was to evaluate the association between air pollution and mental stress among university students. Participants were 11,942 students, who were identified through a multistage survey sampling process conducted in 50 universities.

Association of cigarette production and tobacco retailer density on secondhand smoke exposure in urban China.

Unlabelled: The primary aims of this study are to examine the associations between two key environmental factors-regional cigarette tobacco production and tobacco retail outlet density-and secondhand smoke (SHS) exposure in urban China and to explore the possible mechanisms that explain this association.

Methods: A cross-sectional multistage sampling design was used to collect individual information in 21 cities in China. Environmental variables were retrieved from national databases.

Uncertainty Stress, and Its Impact on Disease Fear and Prevention Behavior during the COVID-19 Epidemic in China: A Panel Study.

We examined changing trends of uncertainty stress, and its impact on disease fear and prevention behaviors during the Chinese COVID-19 epidemic, using a prospective observational study. We employed a longitudinal design. We recruited participants for an online panel survey from chat groups on social media platforms.

Social deprivation and secondhand smoke exposure among urban male residents: A nationwide study in China.

Introduction: Social deprivation is a known determinant of health and related behaviors. Many studies have linked socioeconomic factors to secondhand smoke (SHS) exposure. However, no studies have examined the relationship between social deprivation and SHS exposure.
