Background: Internet addiction (IA) has gained more and more attention for its negative impact on the subjects' study and daily life. However, in a large sample, there is little research on the association between IA and insomnia in Chinese college students. This study aimed to investigate the prevalence of insomnia and its related risk factors among Chinese college students with IA.Methods: A cross-sectional design was used to investigate 627 Chinese college students with IA. Each student completed a survey on demographic data, Internet addiction (Revised Chinese Internet Addiction Scale), depression (Self-Rating Depression Scale), insomnia (Athens Insomnia Scale), anxiety (Self-Rating Anxiety Scale), and suicidal behavior. Binary logistic regression analysis was employed to adjust for confounding factors.Results: The prevalence of insomnia among students with IA was 54.86%. Compared with IA students without insomnia, IA students with insomnia were more likely to be younger, smoking, drinking, have anxiety, depression, suicidal ideations, suicide plans, and suicide attempts (all p < 0.05). Moreover, drinking [OR, 1.664; 95% confidence interval (CI), 1.139–2.431; p = 0.008], anxiety (OR, 2.321; 95% CI, 1.116–4.826; p = 0.024), and suicidal ideation (OR, 1.942; 95% CI:1.295–2.911; p = 0.001) were independently associated with insomnia in IA students.Conclusions: Insomnia is very common in Chinese IA students. Drinking, anxiety, and suicidal ideation are independently correlated with insomnia. This study provides valuable evidence for school counselors and clinical professionals to assess Internet addiction, insomnia, and suicide risk.
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.
Background: Recent studies have reported changes in the electroencephalograms (EEG) of patients with major depressive disorder (MDD). However, little research has explored EEG differences between adolescents with MDD and healthy controls, particularly EEG microstates differences. The aim of the current study was to characterize EEG microstate activity in adolescents with MDD and healthy controls (HCs).Methods: A total of 35 adolescents with MDD and 35 HCs were recruited in this study. The depressive symptoms were assessed by Hamilton Depression Scale (HAMD) and Children's Depression Inventory (CDI), and the anxiety symptoms were assessed by Chinese version of DSM-5 Level 2-Anxiety-Child scale. A 64-channel EEG was recorded for 5 min (eye closed, resting-state) and analyzed using microstate analysis. Microstate properties were compared between groups and correlated with patients' depression scores.Results: We found increased occurrence and contribution of microstate B in MDD patients compared to HCs, and decreased occurrence and contribution of microstate D in MDD patients compared to HCs. While no significant correlation between depression severity (HAMD score) and the microstate metrics (occurrence and contribution of microstate B and D) differing between MDD adolescents and HCs was found.Conclusions: Adolescents with MDD showed microstate B and microstate D changes. The obtained results may deepen our understanding of dynamic EEG changes among adolescents with MDD and provide some evidence of changes in brain development in adolescents with MDD.
