Decision tree-Markov model of perinatal depression screening: a cost-utility analysis.

Background: Perinatal depression affects the physical and mental health of pregnant women. It also has a negative effect on children, families, and society, and the incidence is high. We constructed a cost-utility analysis model for perinatal depression screening in China and evaluated the model from the perspective of health economics.

Factor structure and longitudinal invariance for the Chinese Mainland version of the Edinburgh postnatal depression scale during pregnancy.

Background: There are inconsistent results on the Edinburgh Postnatal Depression Scale's (EPDS) factor structure and longitudinal invariance among different cultures. Furthermore, limited relevant studies in Chinese pregnant women exist.

Purpose: To test the factor structure of the Chinese Mainland EPDS during pregnancy and conduct longitudinal invariance analyses.

The correlation between pregnancy-related low back pain and physical fitness evaluated by an index system of maternal physical fitness test.

To investigate incidence of pregnancy-related low back pain (LBP), evaluate physical fitness objectively during pregnancy and analyze the correlation between LBP and physical fitness of pregnant women, 180 pregnant women including 101 in mid-gestation (14-28 gestational weeks) and 79 in late-gestation (28-37 gestational weeks) were recruited and self-reported their LBP. The aerobic ability such as cardiorespiratory fitness and anaerobic ability including strength, endurance, speed, flexibility, and balance were evaluated by a novel materal physical fitness test system. The correlation between LBP and each component in physical fitness test system was analyzed in SPSS.

Exposure to ambient air pollution with depressive symptoms and anxiety symptoms among adolescents: A national population-based study in China.

Background: Air pollution threatens adolescents' physical health and adversely affects adolescents' mental health. Previous studies mostly focused on the effects of air pollution on physical health, but there were few studies on the effects of air pollution on mental health.

Methods: We collected scores of depressive symptoms and anxiety symptoms from 15,331 adolescents from 43 schools in eleven provinces in September and November 2017.

Effectiveness of mindfulness training on pregnancy stress and the hypothalamic-pituitary-adrenal axis in women in China: A multicenter randomized controlled trial.

Introduction: In the past two decades, mindfulness-based intervention programs have gradually become popular.Many studies have confirmed that these programs can effectively alleviate prenatal stress and negative emotion.The mindfulness-based stress-buffering hypothesis suggests that mindfulness training can induce changes in the levels of the cortisol secreted by the HPA axis, thereby reducing stress susceptibility.

Associations of greenness surrounding schools and self-reported depressive and anxiety symptoms in Chinese adolescents.

Background: The effect of school-based greenness exposure on mental health among adolescents remains unclear. The study aimed to estimate the associations between school-based greenness and depressive and anxiety symptoms among adolescents and explore potential modifier and mediator between the associations.

Methods: A cross-sectional survey involving 15,559 adolescents was conducted in China.

Relationship between school bullying and mental health status of adolescent students in China: A nationwide cross-sectional study.

Introduction: School bullying, as a public health problem, has been linked to many emotional disorders. However, the overall status of school bullying among adolescent students in China is unknown. This nationwide study aimed to investigate school bullying in China and evaluate the relationships between school bullying and mental health status.

Barriers to Adolescent Health Care in Maternal and Children's Healthcare Hospitals: Based on a National Survey in China.

Purpose: Adolescence is a critical period for physical and psychological development; therefore, health interventions at this phase may be especially beneficial. In this study, we aim to describe the distribution of the adolescent health care system in China and to compare the perceived barriers of running an adolescent clinic (AC) proposed by hospitals with corresponding government entities.

Methods: A nationwide online survey was launched by the National Health Commission of China in December 2015, among 116 Maternal and Children's Healthcare (MCH) hospitals located across 24 randomized selected provinces.

Association of health-risk behaviors and depressive symptoms and anxiety symptoms: a school-based sample of Chinese adolescents.

Background Depressive symptoms and anxiety symptoms of adolescents not only affect youth but also have wide-ranging impacts on the health of adults. The study was carried out to determine the epidemiological characteristics of depressive symptoms and anxiety symptoms and the associations between the two and health-risk behaviors in Chinese adolescents. Methods Participants were recruited from the junior and senior high schools in China.

A preliminary cervical cancer screening cascade for eight provinces rural Chinese women: a descriptive analysis of cervical cancer screening cases in a 3-stage framework.

Background: Cascade analysis is an effective method to analyze the processing data of an event, such as a provided service or a series of examinations. This study aimed to develop a primary cervical cancer screening cascade in China to promote the quality of the screening process.

Methods: We designed a cervical cancer screening cascade in China according to the program flow chart.

The role of depressive symptoms, anxiety symptoms, and school functioning in the association between peer victimization and internet addiction: A moderated mediation model.

Background: Both peer victimization and internet addiction are common public health problems for children and adolescents. Several studies found an association between peer victimization and internet addiction, but the mechanism underlying this association remained unclear. This study aimed to determine the mechanisms underlying this association.

Effect of estrogen on gene expression of fatty acid synthase in periosteum.

Background: Estrogen deficiency contributes to postmenopausal osteoporosis. Periosteum might be a potential target of estrogen, but the underlying mechanism at gene level is far from being elucidated. The objective of this study was to investigate the correlation between estrogen and fatty acid synthase (FAS) expression in periosteum.
