| ObjectivesThe study is aiming at investigating the current status of smart phone usage, sleep quality and learning burnout in secondary vocational school students, exploring the effects of smart phone usage on sleep quality and learning burnout, which will provide a scientific basis for the prevention of mobile phone addiction and the correct use of smart phone in secondary vocational school students.MethodsBy using the method of self rating questionnaire survey investigated the demographic characteristics, and the current status of smart phone usage, sleep quality and learning burnout in secondary vocational school students. The date was inputted by using the computer software program of EpiDate3.1and SPSS21.0. Comparison of categorical variables used Chi square test. Quantitative variables were compared by using Independent-Sample-T-Test and One-Way ANVOA. The relationships of variables were by using Spearman correlation analysis and Stepwise Regression.Results1There are352secondary vocational school students in the survey in total, The mean age of research subjects is (18.41±1.793). The students of first grade are180people (51.1%), the second grade are172people (48.9%).There are102boys (29%) and250girls (71%).2In secondary vocational school, there are97.2%students have smart phone,66.7%students using smart phone are not exceeding2years,39.7%students use smart phone time in more than4hours every day,63.7%students’monthly Internet traffic is over150Mb,47.4%and40.9%students "often" use mobile phones before bedtime and in the self-study class, the "often used" functions of smart phone are QQ chat (41.2%) and network music (40.1%). The mobile phone addiction index score of secondary vocational students is (42.28±12.260), mobile phone addicts account for18.1%.3Secondary vocational school students sleep quality score is (3.07 ±1.361). There are168students with poor quality of sleep, accounting for49.1%of the total number. The comparisons of sleep quality in different situations of using smart phone before bedtime have more differences, with statistical significance(P<0.05). There is a significant positive correlation between the total score of sleep quality and the total scores and factors of mobile phone addiction index, with statistical significance (P<0.05).4Learning burnout mean is (44.42±7.969) for secondary vocational students.The total score is90and the scores are mainly concentrated in the40-55points. The comparisons of learning burnout factors in different situations of using smart phone in the self-study class have more differences, with statistical significance (P<0.05). The comparison between smart phone addicts and non addicts has difference in each factor of learning burnout, with statistical significance (P<0.05).Conclusions1Smart phones have gained popularity in the groups of secondary vocational students.Part of the secondary vocational students have the habit of using mobile phone before going to bed and in the self-study class.and the vast majority of students do not give full play to the role in the study of smart phone.The rate of smartphone addiction is much higher. Comparing with the non mobile phone addicts, addicts of secondary vocational school students using smart phones have characteristics such as the long years of using mobile phone, daily use of a long time, high monthly Internet traffic and high monthly mobile phone cost.2The overall situation of sleep quality of secondary vocational school students is poor. The higher of mobile phone addiction tendency, the worse of sleep quality.Using mobile phone before going to sleep can lead to poor sleep, prolong the sleep time and aggravate sleep disorder and daytime dysfunction.3The learning burnout level of secondary vocational students is moderate side on the whole medium. Often using smart phone in the self-study class and break and the higher of mobile phone addiction tendency all can evidently increase in the level of learning burnout. |
