ABSTRACT

Objective@#To describe the prevalence of cell phone dependence and anxiety-depression co morbidity among college students, and to explore the association between cell phone dependence and anxiety-depression co morbidity among college students, in order to provide a reference basis for promoting the development of college students mental health.@*Methods@#Using a prospective study design, baseline survey was conducted in April-May 2019 among a random whole group sample of 1 135 individuals in two universities in Hefei, Anhui Province and Shangrao, Jiangxi Province, and a follow up survey was conducted in November 2019 among the sampled population, with a valid number of 1 110 individuals after matching with the baseline survey. The Self rating Questionnaire for Adolescent Problematic Mobile Phone Use (SQAPMPU) was used to assess college students cell phone dependence, and the Depression Anxiety Stress Self Rating Scale (DASS-21) to assess depression, anxiety, and anxiety depression co morbidity symptoms, and the self administered Health Related Behavior and Mental Health Questionnaire for College Students to report sleep duration.@*Results@#The detection rates of cell phone dependence among college students at baseline and follow up surveys were 24.5% and 27.7%, respectively, and the detection rates of anxiety symptoms, depressive symptoms, and anxiety depression co morbidities were 28.7%, 21.3%, and 18.4%, respectively. The results of the binary Logistic regression model showed that cell phone dependence was positively associated with the risk of anxiety depression co morbid symptoms among college students at baseline ( OR =5.79, 95% CI =4.06-8.24) and after six months of follow up ( OR =2.62, 95% CI =1.86-3.69) ( P <0.01). The results of the moderating effect analysis showed that sleep duration moderated the association between cell phone dependence and anxiety depression co morbidities, and the interaction term was statistically significant ( β =0.08, 0.04, P <0.01).@*Conclusion@#Cell phone dependence in college students increases the risk of depressive and anxiety co morbid symptoms, and sleep mitigates effect of cell phone dependence on depressive and anxiety co morbid symptoms in college students.

ABSTRACT

Objective@#To understand the current situation and influencing factors of Internet addiction among college students after returning to school during the COVID-19 epidemic, and to provide scientific basis for timely intervention measures to adjust the risk factors of Internet addiction.@*Methods@#A cluster sampling method was adopted to conduct a questionnaire survey among 2 700 college students who firstly returned to college using general condition questionnaire and Internet Addiction scale.@*Results@#The detection rate of Internet addiction disorder was 32.4% among returning college students, moreover, the detection rate of Internet addiction in male students(36.0%) was higher than that in female students (31.2%) (χ 2=5.42,P<0.05). The degree of Internet addiction was negatively correlated with the physical health score (r-s=-0.20) and mental health score (r-s=-0.24) of college students (P<0.01). Multivariate Logistic regression analysis showed that compared with introversion, neutral (OR=0.67, 95%CI=0.55-0.82) and extroverted college students (OR=0.59, 95%CI=0.48-0.74) were protective factors for Internet addiction; compared with no exercise, physical exercise ≥3 times or more per week (exercise 3-4 times:OR=0.67, 95%CI=0.51-0.87; ≥5 times:OR=0.67, 95%CI=0.50-0.90) were the protective factors for Internet addiction among college students; family loss during the epidemic was a risk factor for Internet addiction among college students (OR=1.34, 95%CI=1.12-1.60); the risk of Internet addiction was 2.13 times higher for college students who actively sought psychological help than for those who did not seek psychological help (95%CI=1.14-3.96); college students who did not want to go back to school had 1.50 times the risk of Internet addiction as those who did (95%CI=1.26-1.77).@*Conclusion@#The current situation of college students online behaviors during COVID-19 is not optimistic, and should arouse sufficient attention from society and universities. In addition, college students returning to school should take more physical exercises and psychological counseling to detect and intervene in psychological problems in time, reduce their psychological burden, and enhance their psychological quality.

ABSTRACT

Objective@#To exploring the relationship between college students’ mobile phone addiction, social support and depression.@*Methods@#During May 2019, 1 703 students from five universities in Shandong Province were selected to complete a questionnaire composed of Mobile Phone Addiction Tendency Scale(MPATS), Perceived Social Support Scale(PSSS) and Center for Epidemiological Studies Depression Scale(CES-D).@*Results@#The scores of mobile phone addiction, social support and depression among college students were(32.84±9.30)(67.20±11.09)(11.61±8.65). The mobile phone addiction and depression score of the low social support group were significantly higher than those of the high social support group( t =10.01, 15.89, P <0.01). Regression analysis showed that mobile phone addiction in the high social support group explained the depression variation to lower than the low social support group( R 2=0.16, 0.19, P <0.01). Social support had a partial mediating effect on mobile phone addiction and depression. The median effect value was -0.10, accounting for 21.0% of the total effect.@*Conclusion@#College students’ social support has partial mediating effects on the influence of mobile phone addiction on their depression. Improving the social support level of college students is advantageous to reduce the negative impact of mobile phone addiction on their depressive symptoms.

ABSTRACT

Objective@#To explore the impact of function of mobile phone use on self-perceived stress and mobile phone addiction of high vocational students, and the mediating role of coping styles between different mobile phone functions and mobile phone addiction.@*Methods@#A total of 911 participants in two vocational colleges in Wuhan and Liaocheng were investigated by using convenient sampling method. Smartphone Usage, Simplified Coping Style Questionnaire, and Stress subscale of Depression-Anxiety-Stress Scale(short version) were administered to participants.@*Results@#Female students scored significantly higher on mobile phone social features (4.77±1.06) than males( t =2.05, P =0.04), while males scored significantly higher on MPATS and DASS-S, Negative Coping Style subscales than females( P <0.01). The social function of the mobile phone was positively related to the positive coping styles( r =0.17, P <0.01). The game features of mobile phone were positively related to negative coping styles, stress and mobile addiction( P <0.01). Negative coping style could positively predict stress and mobile phone addiction( β =0.53, 0.50, P <0.01). Negative coping styles and stress had significant chain mediation effects in nonsocial functions and mobile phone addiction(95% CI =0.06-0.24, P <0.01).@*Conclusion@#Students of vocational college who often use cellphone not for social purpose have higher self-perceived stress. The game function of mobile phones had an adverse effect on the physical and mental health of vocational students. Negative coping style is a powerful predictor of stress and mobile phone addiction.

Female college students’ life meaning and school adjustment were negatively correlated with mobile phone addiction(r=-0.50, -0.58, P<0.01). Female college students’ life meaning was positively correlated with school adjustment(r=0.51, P<0.01). Having a sense of life meaning and seeking a sense of life meaning could jointly explain 24% of the variation in mobile phone addiction.

ABSTRACT

Objective@#To explore the effectiveness of short-term high-intensity exercise combined with nutritional intervention in female college students with Internet addiction and obesity.@*Methods@#Eighty female internet addicted and obese college students from Shijiazhang Information Engineering Vocational College were recruited into the intervention. They were divided into intervention group and control group (n=40) by random number table method. The control group maintained the original exercise and dietary habits, while the intervention group received nutritional intervention and 8-week high intensity intermittent exercise. Body composition, lipid metabolism index and Internet Addiction Scale scores before and after intervention were compared between the two groups.@*Results@#After intervention, weight, body fat percentage and abdominal fat in the intervention group decreased significantly, while lean mass and bone mass increased significantly(t=7.32,4.95,6.99,3.21,2.78,3.06,P<0.05). Water content did not change significantly. Body weight, body fat percentage and abdominal fat of the intervention group were significantly lower than those of the control group, and lean mass and bone mass of the intervention group were significantly higher than those of the control group(t=-7.87,-9.90,-5.24,2.19,6.17,P<0.05). The level of TG in the intervention group was significantly decreased after intervention, and there was significant difference between the two groups(t=8.76,6.66,P<0.05). After intervention, total and dimensional scores of Internet addiction in the intervention group were significantly lower than those in the control group(t=6.27,4.97,8.21,10.06,5.39,9.25,P<0.05), and the scores of compulsive Internet use behavior, Internet addiction tolerance, withdrawal reaction, time management problems, interpersonal and health problems and total scores in the intervention group were significantly lower than those in the control group(t=-8.61,-5.32,-8.65,-6.69,-5.56,-17.59,P<0.05).@*Conclusion@#Short-term high-intensity exercise and nutritional intervention among obese female college students with Internet addiction shows positive effects in reducing body fat and improving lipid metabolism, as well as Internet addiction.
