Previously, only three species of the genus Neurigona Rondani of the subfamily Neurigoninae were known from Yunnan Province. Here, we reviewed the species of Neurigona from Yunnan and added the following seven new species: N. apicilata sp. nov., N. basicurva sp. nov., N. brevidigitata sp. nov., N. convexa sp. nov., N. huanglianshana sp. nov., N. quadrimaculata sp. nov., and N. ventriprocessa sp. nov. All seven new species are sympatric and were collected from below a reservoir in the Huanglianshan Nature Reserve in Yunnan using three Malaise traps in 2019. This suggests a very high species richness in the Yunnan fauna. A key to the species of Neurigona from Chinese mainland is provided. [ABSTRACT FROM AUTHOR]

Although evidence in supporting the associations between childhood maltreatment (CM), parenting style and anxiety in children and adolescents exists, few high-quality analytical epidemiological studies which focusing on clinically diagnosed anxiety disorders (AD) had been published. The aim of this study was to further corroborate the associations between CM, parenting style, and AD in a large representative sample of Chinese children and adolescents. Study subjects were derived from the Mental Health Survey for Children and Adolescents in Yunnan (MHSCAY), a population-based cross-sectional program. Individually matched case-control study design was adopted. Univariate and multivariate conditional binary logistic regression models were used to estimate the associations between CM, parenting style and AD. Dose-response trends were estimated using the Cochran-Armitage Chi-square test. A series of stratified analyses were conducted to explore effect modification on exposure-outcome association by some important features. Totally we screened out 202 cases and 404 matched controls, with an age mean of 14.43 years. Conditional logistic regression models revealed that EA and a higher level of parental over-protection were significantly associated with increased risk of AD, with adjusted ORs of 3.39 (95 % CI: 2.07–5.56) and 1.93 (95 % CI: 1.28–2.90). Stratified analysis identified noticeable effect modification by sex, age, and whether the only child in the family. Major findings of this study suggested that children and adolescents who had experienced EA or raised up by over-protective parents are at increased risk of AD. Targeted intervention measures should be developed and implemented for these high-risk youths. [ABSTRACT FROM AUTHOR]

The independent associations among childhood maltreatment (CM), parenting style, and school bullying in children and adolescents have not been adequately discussed. Epidemiological evidence of higher quality is still scarce. We intend to investigate this topic by using a case–control study design in a large sample of Chinese children and adolescents. Study participants were chosen from the Mental Health Survey for Children and Adolescents in Yunnan (MHSCAY), a mega ongoing cross-sectional study. The combined database from four study sites was used. The population-based case–control study was individually matched by study site, age, sex, race, left-behind status, whether a single child, and whether a boarding student. Cases were observed to have a significantly higher prevalence of CM, higher scores for parental rejection and over-protection, and lower scores for parental emotional warmth. Multiple conditional logistic regression revealed that CM, especially emotional abuse (EA) and sexual abuse (SA), were associated with a prominently increased risk of school bullying involvement, with adjusted odds ratio (OR) of 2.28 (95 % CI: 2.03, 2.57) and 1.90 (95 % CI: 1.67, 2.17). Subsequent analysis further corroborated the robustness of EA–bullying and SA–bullying associations. Although parenting style generally showed a weaker association with school bullying, a higher level of parental rejection was related to an increased risk of bullying victimization. Chinese children and adolescents who are victims of EA or SA, or experienced a higher level of parental rejection, are more vulnerable to school bullying. Targeted interventions should be designed and implemented. • CM, especially EA and SA, were associated with increased risk of school bullying involvement. • Parental rejection was related to school bullying victimization. • Victims of EA and SA, and adolescents reported higher level of parental rejection should be targeted for intervention.

Background: School bullying victimization is associated with increased risk of anxiety in children and adolescents. However, little is known about the role of resilience in this association. The purpose of this study was to investigate the possible mediation by resilience in this association in a large group of Chinese children and adolescents. Methods: A population-based cross-sectional study adopting two-stage simple random cluster sampling was implemented in Yunnan province, southwestern China. A comprehensive questionnaire was used to collect information from the participants. Among all the participants, 4624 were included in the final analysis. Descriptive statistics were used to present general characteristics of the study participants. Univariate and multivariate logistic regression models were adopted to estimate crude and adjusted associations among bullying victimization, anxiety, and resilience. A path model was used to analyze the hypothesized mediation by resilience in the association between bullying victimization and anxiety. Results: Analytical results of multivariate logistic regression models suggested that bullying victimization was significantly associated with anxiety in Chinese children and adolescents; compared with individuals who had not been bullied, victims of bullying were more likely to experience anxiety symptoms, with an adjusted odds ratio (OR) of 3.02 (95% CI 2.46–3.71). Path analysis revealed a prominent mediating effect of resilience in the association between bullying victimization and anxiety, accounting for 31.89% of the total association. Further analysis indicated that, among the five dimensions of resilience, emotional regulation, interpersonal assistance, and family support were significant mediators, accounting for 30.34%, 10.79%, and 8.35% of the total association. Conclusions: Our major findings highlighted the promising role of resilience-based intervention measures in reducing the risk of anxiety associated with school bullying victimization in Chinese children and adolescents.

Objective: We aimed to investigate the mediation of social support in the association between school bullying and suicidal risk among a large group of Chinese children and adolescents.Method: In this two-wave cross-sectional study, we analyzed 6,063 children and adolescents from southwest China. A two-stage simple random clustering sampling method with probability proportionate to sample size design had been used to select study subjects. Univariate and multivariate Logistic regression models were adopted to determine the inter-associations between school bullying, suicidal risk indicators, and social support. Path models were further fitted to estimate the mediation of social support.Results: Compared with students who were not involved in school bullying, only victimization was associated with increased suicidal risk, the adjusted ORs for suicidal ideation, suicidal plan, and suicidal attempt were 2.06 (95% CI: 1.61-2.65), 2.07 (95% CI: 1.62-2.64), and 2.41 (95% CI: 1.90-3.05), respectively. Path model indicated that parental social support significantly mediated the association between bullying victimization and suicidal risk. For different types of victimization, only relational bullying victimization was associated with increased suicidal risk, social support from classmates and close friends presented as significant mediators.Limitations: Causal inference cannot be made because of cross-sectional study design. Information was collected by using self-reporting method, the possibility of information bias exists. Generalization of study results could be limited.Conclusions: Intervention measures on improving parental and peer social support may be effective in reducing school bullying victimization associated suicidal risk for Chinese children and adolescents.
