Labor Migration of Parents and Aggression Among Their Offspring in China.

Importance: In China, parental labor migration often leaves children behind and is potentially adversely associated with children's health. However, the association between parental migration and aggression among their offspring remains largely underexplored.

Objective: To investigate the associations of parental labor migration with total and subtypes of aggression among their offspring as well as potential sex differences therein.

Shortwave Infrared InGaAs Detectors On-Chip Integrated with Subwavelength Polarization Gratings.

Shortwave infrared polarization imaging can increase the contrast of the target to the background to improve the detection system's recognition ability. The division of focal plane polarization indium gallium arsenide (InGaAs) focal plane array (FPA) detector is the ideal choice due to the advantages of compact structure, real-time imaging, and high stability. However, because of the mismatch between nanostructures and photosensitive pixels as well as the crosstalk among the different polarization directions, the currently reported extinction ratio (ER) of superpixel-polarization-integrated detectors cannot meet the needs of high-quality imaging.

Design and Fabrication of Broadband InGaAs Detectors Integrated with Nanostructures.

A visible-extended shortwave infrared indium gallium arsenide (InGaAs) focal plane array (FPA) detector is the ideal choice for reducing the size, weight and power (SWaP) of infrared imaging systems, especially in low-light night vision and other fields that require simultaneous visible and near-infrared light detection. However, the lower quantum efficiency in the visible band has limited the extensive application of the visible-extended InGaAs FPA. Recently, a novel optical metasurface has been considered a solution for a high-performance semiconductor photoelectric device due to its highly controllable property of electromagnetic wave manipulation.

Association of greenness surrounding school with aggression among adolescents: A multi-site study in China.

Association of greenness surrounding school with aggression among adolescents was not well understood. This study aimed to investigate the associations of greenness surrounding school with adolescents' total and sub-types of aggression and explore potential mediators underlying these associations. A multi-site study of 15,301 adolescents aged 11-20 years were recruited through a multistage, random cluster sampling across 5 representative provinces in mainland China.

Psychometric properties and normative data of the childhood trauma questionnaire-short form in Chinese adolescents.

Background: The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a widely utilized instrument of childhood maltreatment (CM). However, psychometric properties and normative data of the CTQ-SF for Chinese adolescents are still unknown.

Objective: To examine psychometric properties and normative data of Chinese version CTQ-SF in a nationally representative sample of Chinese adolescents, including internal consistency reliability, test-retest reliability, structural validity, and convergent validity.

Sex differences in association between Internet addiction and aggression among adolescents aged 12 to 18 in mainland of China.

Background: Previous studies have reported that Internet addiction (IA) is an important predictor of aggression. However, little is known whether aggression is a risk factor of IA. This study aims to explore whether IA can predict total and sub-types of aggression, whether aggression also can predict IA, and the potential sex difference.

Co-occurrence of sibling and peer bullying victimization and depression and anxiety among Chinese adolescents: The role of sexual orientation.

Background: Bullying victimization is a robust predictor of mental distress among lesbian/gay, bisexual, and questioning (LGBQ) adolescents. However, few research accounted bullying victimization within the context of both sibling and peer relationships.

Objective: To examine the effect of sibling and peer bullying victimization on depression and anxiety between heterosexual adolescents and LGBQ adolescents.

Interaction between Sirtuin 1 (SIRT1) polymorphisms and childhood maltreatment on aggression risk in Chinese male adolescents.

Background: Aggressive behavior is a highly prevalent and serious public health problem among adolescents. However, the etiology and pathogenesis of aggressive behavior remain unclear. Childhood maltreatment is an acknowledged factor for aggressive behavior.

Gene-environment interactions between CREB1 and childhood maltreatment on aggression among male Chinese adolescents.

Both the genetic and environmental factors may affect aggression susceptibility. However, the conclusions of these associations remain discrepant. In addition, studies that explored the association between CREB1 and aggression were meager.

Associations between screen time, physical activity, and depressive symptoms during the 2019 coronavirus disease (COVID-19) outbreak among Chinese college students.

Background: The 2019 novel coronavirus disease (COVID-19) emerges in China, which spreads rapidly and becomes a public health emergency of international concern. Chinese government has promptly taken quarantine measures to block the transmission of the COVID-19, which may cause deleterious consequences on everyone's behaviors and psychological health. Few studies have examined the associations between behavioral and mental health in different endemic areas.

The economic benefits of increased sugar-free chewing gum in China: a budget impact analysis.

Background: To analyze the potential cost savings in dental care associated with increased sugar-free gum (SFG) use among Chinese teenagers and adults.

Methods: The amount of SFG chewed per year and decayed, missing and filled teeth (DMFT) was collected from a cross-sectional survey to create a dose-response curve assumption. A cost analysis of dental restoration costs was carried out.

Circadian rhythm abnormalities during the COVID-19 outbreak related to mental health in China: a nationwide university-based survey.

Objective/background: School closure and home quarantine has been implemented worldwide during the coronavirus disease 2019 (COVID-19) outbreak. The study aims to assess the associations of circadian rhythm abnormalities (CRA) during the COVID-19 outbreak with mental health in Chinese undergraduates.

Methods: A nationwide cross-sectional university-based survey was conducted from 4th February to 12th, 2020.
