Correlations Between Mobile Phone Dependence (MPD) And Sleep Quality In Secondary Vocational Medical School Students Majoring In Nursing

Objective: To investigate mobile phone dependence (MPD) in Secondary vocationalmedical school students majoring in nursing to understand the relationship betweenMPD and sleep quality for evidence of prevention interventions and the sleep qualityimprovement.Method: By randomized cluster sampling methods,542local Medical school studentsmajoring in nursing were investigated anonymously through questionnaire includingthe general situation of the students, phone usage, self-assessment questionnaire onMPD among young students, and the Pittsburgh Sleep Quality Index (PSQI)scale.descriptive statistics analysis, t test, analysis of variance, correlation analysis andmultiple linear regression statistical method were used to discuss nursing students’MPD, sleep quality and influencing factors.Results:1. There were138in high score group of MPD, The rates of cell phone addictionwere25.5%2. No difference in grades (F=1.176,P＞0.05),students source (F=2.872,P＞0.05)and the years of phone uses (F=0.208，P＞0.05),but there is significant difference inage （F=8.819,P＜0.01）,family economic status (F=8.689,P＜0.01), only child or not（t=2.052,P＜0.01）, smart phone or not （t=4.632,P＜0.01）,daily use time （F=32.872,P＜0.01）, monthly usage charges (F=14.817, P＜0.01), monthly Mobiledata traffic （F=5.467,P＜0.01）, average daily amount of SMS（F=5.304,P＜0.01）3.26.8%of the secondary vocational nursing students sleep quality is poor.4.MPD score has a positive correlation with the quality of sleep PQSI score(r=0.409,P＜0.01). Multiple linear stepwise regression showed that PQSI scores maybe affected by MPD score (β=0.113, P <0.01)Conclusion:1. MPD appeared prevalent in vocational nursing students, students who was theone-child, family economic condition better,using a smart phone, daily use mobilephone time for more than2hours,or higher in monthly mobile data traffic, usagecharges and average daily amount of SMS has higher MPD degree.2. MPD would result in sleep quality,Education on the fewer use of mobilephones may be helpful to improve sleep quality．...
