Association between sleep quality and anxiety-depression co-morbid symptoms among nursing students of medical college in Hefei City / 中国学校卫生

Objective@#To describe the prevalence and association of sleep quality and anxiety-depression co-morbid symptoms among nursing students, in order to provide a reference basis for promoting the development of nursing students mental health.@*Methods@#Using a prospective study design, baseline survey was conducted in January 2019 among a random cluster sample of 1 716 individuals in three medical universities in Hefei, Anhui Province, and a follow-up survey was conducted in October 2019, with a valid number of 1 573 individuals after matching with the baseline survey. The Pittsburgh Sleep Quality Index (PSQI) was used to assess nursing students sleep quality, and the Depression Anxiety Stress Scale (DASS-21) to assess the anxiety-depression comorbid symptoms.@*Results@#The detection rates of anxiety-depression co-morbidities among nursing students at baseline and follow-up survey were 16.9% and 18.2%, respectively, and the detection rates of poor sleep quality among nursing students at baseline and follow-up survey were 10.1% and 10.3%, respectively. The results of the binary Logistic regression model showed that baseline PSQI score were positively associated with the risk of anxiety-depression co-morbid symptoms among nursing students at baseline ( OR=1.49, 95%CI =1.40-1.59) and after nine months of follow-up ( OR=1.22, 95%CI =1.16-1.28). Furthermore, the influence of baseline sleep quality on the risk of anxiety-depression co-morbid symptoms were mainly concentrated in the five dimensions of sleep time, sleep efficiency, sleep disorders, hypnotic drugs and daytime dysfunction, and such effects of sleep time, sleep disorders and daytime dysfunction still existed in the follow-up investigation.@*Conclusion@#Poor sleep quality of nursing students can increase the risk of anxiety-depression co-morbidities. Improving sleep quality of nursing students has a positive effect on improving their mental health.

Association between cell phone dependence and anxiety-depression co morbid symptoms among college students / 中国学校卫生

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.

Mobile phone dependence and gray matter volume in college freshmen / 中国学校卫生

Objective@#This study aimed to investigate the correlation between brain gray matter volume(GMV) and MPD based on voxel-based morphometry(VBM) method.@*Methods@#By using principle of random sampling method, 566 students were recruited from 5 different majors in a certain university. An electronic questionnaire was used to collect the general situation and MPD. Moreover, 266 students were obtained high-resolution 3-dimensional T1 structure images by 3.0 T MRI based on voluntary principle. A multiple regression model with VBM8 was performed to detect GMV associated with MPD scores.@*Results@#Among the 266 participants, 81 students(30.5%) reported MPD. There were no statistical differences of MPD scores between different characteristics, such as gender, residential area, sibling and perceived family income, as well as academic performance(t/F=-1.04,0.40,-1.30,0.23,1.48,P>0.05). An inverse correlation was found between GMV of the anterior cingulate gyrus(ACC) and right fusiform gyrus(FFG) with MPD scores(FDR corrected, P<0.05), and no positive associations were found.@*Conclusion@#College students with higher severity of MPD have lower GMV of ACC and right FFG, and these results suggested that MPD was correlated with brain reward, executive control and emotional related GMV.

Study on the relationship between physical activity and physical, mental health of college students / 中国学校卫生

Objective@#To describe physical activity (PA) level of college students, and to examine the associations between PA and physical health and depression, so as to provide evidence for health promotion of college students.@*Methods@#During June to July 2018, a cross-sectional survey was conducted among 4 624 college students from 2 universities in Anhui and Jiangxi provinces. The basic information was investigated by the questionnaire. PA was assessed by the International Physical Activity Questionnaire(IPAQ). Physical and mental health were evaluated by the 36-item Short Form Health Survey Questionnaire (SF-36) and the Center for Epidemiologic Studies Depression Scale(CES-D), respectively.Chi-square test was used to examine the differences between physical health and depression among college students with different demographic characteristics. The generalized linear model and binary logistic regression model were used to analyze the relationships between PA and physical health and depression.@*Results@#The proportion of good, medium and poor physical health were 64.5%, 31.6% and 3.9%, respectively. The detection rate of depression was 34.1%. Compared to low PA group, physical health was negatively correlated with medium PA (OR=0.78, 95%CI=0.66-0.91) and high PA(OR=0.46, 95%CI=0.38-0.56). Binary logistic regression results showed that, depression was negatively associated with medium PA (OR=0.69, 95%CI=0.59-0.82) and high PA(OR=0.66, 95%CI=0.55-0.79)(P<0.05). @*Conclusion@#There is a significant association between PA and physical health and depression. Further longitudinal studies are needed to clarify the causal relationship between PA and physical and mental health.
