Background Minimally invasive facial cosmetic surgery (MIFCS) is becoming more and more popular and acceptable in Chinese young people, and it influences people in many aspects. However, there is little research on the associations between MIFCS and psychopathology in Chinese college students. The purpose of this study was to identify the prevalence of MIFCS and its associated factors among Chinese college students. Methods A cross-sectional design was applied in this study. A total of 8089 students completed an online questionnaire on demographic data, depressive symptoms (Self-Rating Depression Scale), anxiety symptoms (Self-Rating Anxiety Scale) and MIFCS. Logistic regression was used to identify independent factors associated with MIFCS. Results The prevalence of MIFCS in Chinese college students was 2.7% (221/8098). Students with MIFCS were more likely to be from urban areas, from a single child household, experience depression or anxiety and have a history of smoking (all p < 0.05). They were also less likely to be right-handed or have a good relationship with father or mother (all p < 0.05). Binary logistic regression showed that older age (OR,1.162; 95%CI [1.061,1.273]), female sex (OR,1.837; 95%CI [1.352, 2.497]), community (urban) (OR,0.601; 95%CI [0.441,0.818]), right-handedness (OR,0.668; 95%CI [0.454,0.985]), depressive symptoms (OR, 4.708; 95%CI [1.690,13.112]), family income (30,000–70,000 yuan per year) (OR,0.572; 95%CI [0.403,0.812]) and smoking (OR,1.571; 95%CI [1.09,2.423]) were independently associated with MIFCS. Conclusions Minimally invasive facial cosmetic surgery (MIFCS) is very common in Chinese college students, indicating the importance of paying attention to MIFCS. This study provides valuable evidence for college counselors and doctors in the cosmetic department to provide better and healthier services to students who undergo MIFCS, especially those with depressive symptoms.

ObjectivesCyberbullying is quite common in adolescents and college students, and it influences mental health in many aspects. The purpose of this study was to investigate the prevalence of cyberbullying in Chinese college students and to look for related factors.MethodsEight thousand and ninety-eight college students aged 17–26 were enrolled in this cross-sectional study. We collected information of their sociodemographic data, depression (evaluated by Self-Rating Depression Scale), anxiety (evaluated by Self-Rating Anxiety Scale), lifetime suicidal behaviors (including suicidal ideation, suicidal plans, and suicide attempts), and experiences of cyberbullying for the past 12 months by online questionnaires.ResultsThe prevalence of cyberbullying for the past 12 months was 7.82% (633/8,098) among college students. Binary logistic regression analysis showed that sex (odds ratio, OR = 0.522, 95%CI = 0.433–0.629, p &lt; 0.001), suicide attempts (OR = 2.164, 95%CI = 1.589–2.948, p &lt; 0.001), depression (OR = 2.372, 95%CI = 1.602–3.512, p &lt; 0.001), and anxiety (OR = 1.911, 95%CI = 1.305–2.800, p = 0.001) were independently associated with cyberbullying.ConclusionCyberbullying is very common among college students in Hunan Province, China. Besides, being male, suicide attempts, depression and anxiety were independently associated with cyberbullying, which highlights the importance of paying attention to cyberbullying and addressing anxiety, depression, and suicidal behaviors among college students to better improve their mental health and prevent suicide.

BackgroundChildhood maltreatment has been identified as a risk factor for depressive symptoms. Social anxiety is closely associated with depression. Physical activity has been regarded as an underlying protective factor. Little is known about the complex relations among these factors in Chinese middle school students. This study aimed to explore whether social anxiety mediated the association between childhood maltreatment and depressive symptoms and investigate whether physical activity moderated the indirect or direct effect of the mediation model.MethodsA total of 1,570 middle school students were recruited and measured for childhood maltreatment (measured by Childhood Trauma Questionnaire—Short Form Chinese version), social anxiety (as the mediator, measured by the Chinese simplified version of Social Anxiety Scale for Adolescents), depressive symptoms (measured by the Chinese version of Depression Anxiety Stress Scales-21), physical activity (as the moderator), and covariates such as age, sex, and nationality. The proposed relationships were tested using mediation and moderated mediation models.ResultsEmotional abuse was directly associated with depression, and the association between emotional abuse and depression was partially mediated by social anxiety. The associations between emotional abuse with depression and with social anxiety were moderated by physical activity.ConclusionThis study revealed the mediating role of social anxiety and the moderating role of physical activity between emotional abuse and depression, which emphasizes the potential benefits of sufficient physical activity to reduce social anxiety and depressive symptoms, and more intervention studies should be conducted to explore the direct influence of sufficient physical activity in the future.
