ABSTRACT
Objective@#This cross-sectional study explores the serial multiple mediation of the correlation between internet addiction and depression by social support and sleep quality of college students during the COVID-19 epidemic. @*Methods@#We enrolled 2,688 students from a certain university in Wuhu, China. Questionnaire measures of internet addiction, social support, sleep quality, depression and background characteristics were obtained. @*Results@#The prevalence of depression, among 2,688 college students (median age [IQR]=20.49 [20.0, 21.0] years) was 30.6%. 32.4% of the students had the tendency of internet addiction, among which the proportion of mild, moderate and severe were 29.8%, 2.5% and 0.1%, respectively. In our normal internet users and internet addiction group, the incidence of depression was 22.6% and 47.2%, respectively. The findings indicated that internet addiction was directly related to college students’ depression and indirectly predicted students’ depression via the mediator of social support and sleep quality. The mediation effect of social support and sleep quality on the pathway from internet addiction to depression was 41.97% (direct effect: standardized estimate=0.177; total indirect effect: standardized estimate= 0.128). The proposed model fit the data well. @*Conclusion@#Social support and sleep quality may continuously mediate the link between internet addiction and depression. Therefore, the stronger the degree of internet addiction, the lower the individual’s sense of social support and the worse the quality of sleep, which will ultimately the higher the degree of depression. We recommend strengthening monitoring of internet use during the COVID-19 epidemic, increasing social support and improving sleep quality, so as to reduce the risk of depression for college students.
ABSTRACT
Objective@#The purpose of this cross-sectional survey is to explore the current state of Internet addiction (IA) in Chinese medical students and its connection with medical students’ sleep quality and self-injury behavior. @*Methods@#Respondents were came from Wannan Medical College, China. The Young’s Internet Addiction Test, Pittsburgh Sleep Quality Index (PSQI), Self-Harm Questionnaire were used in this cross-sectional survey. A total of 3,738 medical students were investigated, 1,552 (41.52%) males, 2,186 (58.48%) females. T-test, chi-square test and MANOVA were used for data analysis. @*Results@#Of the 3,738 medical students, 1,054 (28.2%) reported having IA, 1,126 (30.1%) reported having poor sleep quality, 563 (15.1%) having self-harm behaviors. IA tends to be more female, upper grade students. The sleep quality of IA was worse than that of non-IA (χ2=54.882, p<0.001), and the possibility of self-injury was higher than non-IA (χ2=107.990, p<0.001). @*Conclusion@#This survey shows that the IA detection rate of medical students was 28.2%. Females, higher grade students had a higher IA detection rate. The low sleep quality and self-injury behavior of medical students are associated with IA.
ABSTRACT
Objective@#To analyze the current situation of the knowledge, attitudes and practice about Novelcoronavirus pneumonia (NCP) of the residents in Anhui Province.@*Methods@#Anonymous network sampling survey was carried out with an electronic questionnaire that designed by the questionnaire star, and a total of 4016 subjects from Anhui province were investigated. The content of the survey includes that the basic information of subjects,the residents’ knowledge, attitudes and practice about NCP, as well as their satisfaction with the prevention and control measures adopted by the government and health authorities and the suggestions on future prevention. The questionnaire doesn’t involve any privacy information, and all questions were mandatory to ensure the response rate.@*Results@#The M (P25, P75) age the 4016 subjects was 21 (19, 24), and the ranging from 7 to 80 years old. The number of males was1431(35.6%). Social networking tools such as WeChat and QQ were the main sources of epidemic information for residents (97.8%, 3 929 respondents). Residents have a high awareness rate of the main symptoms, transmission routes, using of masks, hand washing and treatment information of NCP, while a low awareness rate of the atypical symptoms. 92.6% of the subjects (n=3 720) think that the outbreak was scary. In terms of psychological behavior scores, the results showed that female (9.38±4.81), the urban (9.37±5.02) and the medical workers (10.79±5.19) had a poorer mental health than the male (8.45±5.00) , the rural (8.71±4.75) and the non-medical workers (the students: 8.85±4.83; public institude workers: 9.02±5.08; others: 8.97±5.39) (P < 0.05). 71.9% of the residents (n=2 887)were satisfied with the local epidemic control measures. The residents took various of the measures to prevent and control the epidemic. The ratio of residents that could achieve "no gathering and less going out" , "wear masks when going out" and "do not go to crowded and closed places" was up to 97.4% (n=3 913), 93.6% (n=3758) and 91.5% (n=3 673) respectively.@*Conclusion@#The residents in Anhui province have a good KAP about NCP, yet it is necessary to strengthen the community publicity, the mental health maintenance of residents and students’ health education.

Objective To evaluate the application effect of‘incorrect cases’in medical statis-tics teaching. Methods The junior students (n=307)of clinical medicine were selected as research subjects by random cluster sampling. They were divided into the teaching improving group (n=151) who accepted case teaching and control group (n=156)who accepted traditional teaching. At the end of the term,the teaching effect was surveyed by questionnaires and compared between the two groups. Measurement data was analyzed by t test,enumeration data by χ2 test and ranked data by rank sum test. Results Students' interests of medical statistics and understanding the importance of the course in teaching improving group were significantly higher than that in control group (Z=-2.375,P=0.018;Z=-2.971,P=0.003). The proportion of students with learning difficulties in teaching improving group was obviously lower than that in control group (Z=-2.488,P=0.013). The satisfaction with theory and practical teaching in teaching improving group (84.10% and 88.74%,respectively)was significantly higher that in control group (73.08%and 71.79%,respectively)(χ2=5.530,P=0.013;χ2=13.841,P<0.001). Although no difference was observed in the test score between the two groups (t=1.230,P=0.220),knowledge of parameter estimation,hypothesis testing and science research design in teach-ing improving group was significantly higher than that in control group (χ2=6.829,P=0.009;χ2=5.835, P=0.016). Conclusions Application of ‘incorrect cases’in medical statistics teaching could arouse students' learning interests and improve clinical medical students' comprehensive analy sis ability of medical statistics.
ABSTRACT
Objective To understand the medical college students' knowledge,attitude and behavior of AIDS,and provide the basis for health education programmes.Methods 2 130 school students were recruited by cluster sampling method in one medical college,including 717 freshman,533 sophomore and 880 junior.Questionnaire was used to investigate AIDS-related knowledge,attitudes and behaviors to all of the 2 130 students.Results The correct answer rate was 80.72%,which was positively correlated with the grade,but the knowledge of non-AIDS transmission and detection techniques was still not very clear,such as mosquito bites,sharing towels and clothing with AIDS patients could spread the AIDS or not,the correct answer rate was just 36.7% and 54.3%.There was a certain attitude of discrimination in medical students on AIDS,79.9% of medical students were unwilling to shopping at the place of AIDS patients,and 76.4% were unwilling to have dinner with AIDS patients.Compared with the freshmen,high-grade students have higher knowledge level on HIV/AIDS,but their attitude to AIDS patients was poor.Conclusions Presently,medical students' recognizing on HIV/AIDS still have a long distance from the professional requirements,suggesting that AIDS health education in medical college students is necessary.
ABSTRACT
Objective To explore the previous and current status of hypertension, hyperglycemia and hyperlipidemia in teachers of the primary and middle high schools of Wuhu city. Methods 2 026 teachers aged 30~85 yrs were cluster sampled from 10 primary and 10 middle high schools in WuHu city. They were investigated on their previous examination of blood pressure, blood glucose & lipids, and current prevalence of hypertension, hyperglycemia and hyperlipidemia. Results The previous detection rates of the blood pressure, blood glucose and the blood lipid were 65.24%, 35.21% and 37.84%, respectively. The female previous detection rate of blood glucose and lipids was significant higher than those of the male (?2=4.42,P=0.035;?2=5.42, P=0.020). The result of trends test showed that detection rates were increased with the age increasing. The prevalence of hypertension, hyperglycemia and hyperlipidemia were 21.39%, 3.21% and 37.90%, respectively, among the participations without previous detection for the blood pressure, blood glucose and blood lipid, the hypertension prevalence was significant difference between the male and female participations (26.29% vs 18.68%; ?2=5.58, P=0.018). The medication compliance rate of the hypertensions, hyperglycemia and hyperlipidemia were 70.75%, 70.74% and 15.18% and the control rates were 47.04%, 72.22% and 5.85%. Concludes It is important to strengthen the detection of the blood pressure, blood glucose and blood lipid in community population in order to prevent and control the cardiovascular diseases.
