The mental health of women with polycystic ovary syndrome: a systematic review and meta-analysis.

Polycystic ovary syndrome (PCOS) has been proposed to be associated with several mental health problems, including anxiety, depression, diminished sexual satisfaction, and lowered health-related quality of life, etc. A systematic review and meta-analysis of published literature was conducted comparing the mental health of women with and without PCOS. Ten English and Chinese databases were searched up to 12/31/2018. Random-effects models were introduced, and subgroup analysis, sensitivity test, and meta-regression were carried out to determine the source for heterogeneity among studies. Forty-six studies, including 30,989 participants (9265 women with PCOS and 25,638 controls), were qualified for review according to the inclusion criteria. Twenty-eight studies reported depression symptoms, 22 studies were on anxiety, 16 studies showed quality of life (QoL) status, 12 studies were about sexual dysfunction, five on emotional distress, four on binge eating, and four on somatization. Women with PCOS reported significantly higher depression (SMD = 0.64; 95% CI 0.50-0.78), anxiety (SMD = 0.63; 95% CI 0.50-0.77), lower QoL (SMD = - 0.55; 95% CI -0.69 to -0.40), and not significant sexual dysfunction (SMD = - 0.24; 95% CI - 0.49 to 0.01). Studies from different countries, adopting various diagnosis criteria, using diverse instruments, as well as in different years, have reported heterogenetic results. Women with PCOS in China reported a larger effect size of depression and anxiety than patients from other countries. The results of this study have indicated that women with PCOS suffer from depression, anxiety, and experience a lower quality of life, whereas their sexual function is not distinct from that of healthy women. Psychological health care interventions for women with PCOS were addressed.

Effects of multidimensional child poverty on children's mental health in Mainland China.

This study aimed to investigate the effects of multidimensional child poverty on children's mental health in Mainland China. The data were based on a survey of children in 2015 conducted by multi-stage cluster random sampling method in Xiushui, where levels of poverty are very high. Structural equation model was adopted to analyze the data and test the hypothesized model. Results showed that multidimensional child poverty had a significant effect on both negative mental health and positive mental health of children, and the seven indicators of multidimensional child poverty all had slightly different effects on children's mental health.

The mediating effect of self-esteem on the relationship of living environment, anxiety, and depression of underprivileged children: A path analysis in Chinese context.

This study aimed to explore the relationships of living environment, self-esteem, anxiety, and depression of children in poverty. A sample of 1314 children (grades 4-9) was collected by a school-based survey in Xiushui city, Mainland China. Structural equation modeling was adopted to analyze the data and verify the hypothesized model. Results showed that living environment was negatively correlated with poor children's anxiety and depression levels, and self-esteem had a mediating effect on the relationship between living environment and the mental health of underprivileged children. Based on these findings, we proposed relevant theoretical and practical implications.

Impact of PM2.5 on Second Birth Intentions of China's Floating Population in a Low Fertility Context.

The total fertility rate of the Chinese population has declined dramatically over the last three decades. Research has substantiated the causal link between particulate matter (PM) and adverse health effects. However, the impact of PM on the birth intentions or fertility behavior of the childbearing population remains understudied. The paper analyzes the impact of PM2.5 concentration (a mixture of extremely small solid particles and liquid droplets found in the air) on the second birth intentions of the Chinese floating population. We used urban migrant population matching data at the prefectural level for the analysis. The unique datasets were derived from the Chinese Floating Population Dynamic Survey in 2014 administered by the National Health Commission, the National Prefecture-level City Matching Data administered by the National Bureau of Statistics of China, and the air pollution index PM2.5 collected by the Green Peace Organization. The results show that PM2.5 concentration has a negative impact on the second birth intentions of the floating population. This impact exhibits marked regional heterogeneity: the desire for a second birth across migrant groups living in south China decreases if PM2.5 concentration goes up, while migrants coming from, and living in, north China show strong intentions to have a second birth despite an increase in PM2.5 concentration in northern cities. The results have direct implications for the Chinese government at various levels to play a vital role in making and implementing environmental policies on the mitigation of smog to effectively safeguard the health of individuals and communities and potentially raise China's fertility rate.

Family social capital mediates the effect of poverty on children's anxiety and depression.

This study aims to examine how family social capital mediates the relationship between poverty and children's anxiety and depression in mainland China. Data were collected with multistage cluster random sampling method in Xiushui City in mainland China. The sample comprised 1,314 school-aged children (Grades 4-9). Data included children's basic demographics, internalizing symptoms, and parenting process. Structural equation modeling was used to test the hypothesized model. The results demonstrated a good fit for the sample. The overall model explained 12.7% and 16.1% of the variance for children's anxiety and depression, respectively. Poverty had a significantly direct effect on children's anxiety and depression, and family social capital could partially mediate the influence of poverty on children's internalizing symptoms. Family social capital plays an important mediating role between poverty and children's mental health. Our findings provide strong evidence for social work intervention. Family social capital is essential for parent-child interactions, especially in underprivileged families.

The factor structure of the 12-item general health questionnaire (GHQ-12) in young Chinese civil servants.

BACKGROUND: The 12-item General Health Questionnaire (GHQ-12) is a commonly used screening instrument for measuring mental disorders. However, few studies have measured the mental health of Chinese professionals or explored the factor structure of the GHQ-12 through investigations of young Chinese civil servants. METHOD: This study analyses the factor structure of the GHQ-12 on young Chinese civil servants. Respondents include 1051 participants from six cities in eastern China. Exploratory Factor Analysis (EFA) is used to identify the potential factor structure of the GHQ-12. Confirmatory Factor Analysis (CFA) models of previous studies are referred to for model fitting. RESULTS: The results indicate the GHQ-12 has very good reliability and validity. All ten CFA models are well fitted with the actual data. CONCLUSION: All the ten models are feasible and fit the data equally well. The Chinese version of the GHQ-12 is suitable for professional groups and can serve as a screening tool to detect anxiety and psychiatric disorders.
