Subjective sleep quality relationship between Type D personality and lifestyle in health education students

Aim of the study: to assess the relationship between subjective sleep quality and health type D personality and lifestyle among health science students. Research Methods: students from Oral Hygiene, Occupational Therapy, Physiotherapy, Nursing, and Public Health at Lithuanian University of Health Sciences 2nd and 3rd courses have attended this research. An instant cross-sectional study was conducted in 2019 from October – December. During an online anonymous survey, subjects completed a questionnaire based on the \"Pittsburgh Sleep Quality Index\" (PMKI) used to measure sleep quality. To evaluate the D type personality assessment uses the \"14 Statement Type D Scale\" (DS 14). The International Physical Activity Questionnaire (IPAQ) is used to determine the level of physical activity. Also, these variables as alcohol use in the AUDIT (Alcohol Use Disorders Identification Test), smoking, electronic communication at bedtime, and eating habits at bedtime were evaluated. Differences between qualitative traits were assessed using the chi-square (χ2) criterion and the Z criterion. Quantitative attributes for evaluating relationships were calculated using the Spearman coral. ANOVA or Kruskal-Wallis test was used to assess changes in quantitative traits. Results: poor subjective sleep quality was reported by 60,6 % subjects. 49 % of the students who participated in the study had type D personality. Sleep latency (Z = -3,828; p = 0,001), number of sleep disorders (Z = -2,090; p = 0,037), total sleep quality questioner sum (Z = -3,388; p = 0,001) were higher among type D personality students compared with non-type D students and and also daytime dysfunctions were more frequently complained of by type D personality compared to non-type D students (Z = -3,236; p = 0,001). Moderately physically active students reported better subjective sleep quality than physically inactive and intensely active students (Z=-3,139; p=0,002). The high-risk group of alcohol-consuming students experienced statistically significantly worse daytime dysfunctions (Z=-3,496; p=0,001) than the low-risk group. Students who snacked before sleep (91,3 %) had shorter sleep duration (Z = -2,068; p = 0,039) and were said to have more frequent daytime dysfunctions (Z = -2,451; p = 0,014) than non-snacked before sleep. 15,4 % of participants stated that they snack during night, however, no statistically significant relationship was found between the nighttime snacking and the PMKI components. Most students (75 %) do not smoke. A correlation between smoking and sleep quality shows that students who do not smoke have a lower standard of sleep than smokers (Z=-2,211; p= 0,027). After evaluating 78,8 % of the respondents reported using electronic means of communication. The study found out that users who do not use electronic means of communication 1 hour before sleep had less common sleep disorders than those who were using
