Objective: To explore the related factors of college students social network addiction based on problem behavior theory, so as to provide a basis for improving social networking addiction in this population. Methods: From May to June 2023, a method combining convenient sampling and cluster random sampling was used to select 1 768 college students from five universities in Shanghai for a questionnaire survey on social networking addiction, self esteem, loneliness, depressive symptoms, social support, interpersonal needs, sense of distress and frustration; at the same time, the physical exercise, smoking and drinking of college students were investigated. Multivariate Logistic regression analysis was applied to explore the association between the three systems of the problem behavior theory (personality, behavior, and social environment) and social networking addiction among college students. Results: The score on the Social Network Addiction Tendency Scale was (21.08±6.29) among college students, and the detection rate of social networking addiction was 66.29%. After adjusting for gender, family economic status, parental divorce status, and whether being an only child, multivariate Logistic regression analysis showed that in the personality system, higher loneliness ( OR =1.66) and higher depressive symptoms ( OR =2.18) were associated with increased risk of social networking addiction among college students; in the behavior system, alcohol consumption ( OR =1.42) was associated with higher risk of soical networking addiction compared to non drinkers; and in the social environment system, low social support ( OR =1.43) was associated with increased risk of social networking addiction (all P <0.05). Conclusions The rate of social networking addiction among college students is relatively high, and the systems of personality, behavior, and social environment are all related to social network addiction. Providing social support, cultivating healthy lifestyle habits, and increasing interpersonal interactions may help reduce excessive dependence on social networking among college students.

Objective To explore the application of serum signal transducers and activators of transduction 3(STAT3)and SMAD4 expression levels in the early diagnosis and clinical staging of primary glaucoma patients.Methods 86 patients with primary glaucoma admitted to Cangzhou Eye Hospital from August 2021 to May 2023 were selected as the study group,according to the clinical symptoms and visual examination results of the research group,they were divided into mild injury stage(n=30),moderate injury stage(n=34)and severe injury stage(n=22).Another 86 healthy individuals who underwent physical examinations in Cangzhou Eye Hospital during the same period were collected as the control group.Enzyme linked immunosorbent assay(ELISA)was applied to detect the expression levels of serum STAT3 and SMAD4.Multivariate Logistic regression was applied to analyze the relevant factors affecting clinical staging of primary glaucoma,receiver operating characteristic(ROC)curve was applied to analyze the diagnostic value of serum STAT3 and SMAD4 in patients with moderate/severe primary glaucoma injury.Results The expression levels of serum STAT3(13.96±3.45 ng/ml)and SMAD4(11.23±2.85 ng/ml)in the study group were obviously higher than those in the control group(9.83±1.72 ng/ml,7.78±1.95 ng/ml),the differences were statistically significant(F=13.085,17.513,all P＜0.05).The expression levels of serum STAT3(11.88±2.52 ng/ml,13.85±3.51 ng/ml,16.96±4.63 ng/ml)and SMAD4(9.15±1.95 ng/ml,11.23±2.83 ng/ml,14.08±4.12 ng/ml)in patients with primary glaucoma in mild,moderate and severe injury groups were gradually increased,the differences were statistically significant(F=13.085,17.513,all P＜0.05).There was a statistically obvious difference in intraocular pressure among patients with mild,moderate(24.21±5.03 mmHg,28.16±6.31 mmHg,32.26±7.57mmHg),and severe injuries(F=10.577.P＜0.05).serum STAT3[OR(95%CI)=2.728(1.409～5.281)],SMAD4[OR(95%CI)=2.849(1.507～5.387)],and intraocular pressure[OR(95%CI)=2.435(1.094～5.417)]were risk factors affecting clinical staging of primary glaucoma(all P＜0.05).The area under the curve(AUC)of the combined diagnosis of serum STAT3 and SMAD4 for moderate/severe injury in patients with primary glaucoma was 0.963(95%CI:0.899～0.992),which was superior to their respective individual diagnoses(Z =2.558,1.961;P=0.010,0.049),their sensitivity and specificity were 96.43%and 83.33%,respectively.Conclusion The higher the expression levels of STAT3 and SMAD4 in serum,the more severe the clinical symptoms in patients.The combined detection of the two has good diagnostic value for patients with moderate/severe injury.
