Insomnia and the level of stress among students in Krakow, Poland.

INTRODUCTION: Stress and insomnia are increasing problems in young people in highly developed countries. They influence both the physical and psychological aspects of life and seem to be related to each other. Various strategies to cope with stress exist and can be used to reduce its level. The main goal of our study was to find a relationship between insomnia, stress, stress-coping strategies and selected social and medical factors among students. METHODS: A cross-sectional study was conducted in March 2017 among students of seven public Krakow universities, using the Perceived Stress Scale 10, an abbreviated version of the Coping Orientation to Problems Experienced inventory (mini-COPE inventory) and the Athens Insomnia Scale. In the statistical analysis, the chi-square, Student's t test and Spearman's rank correlation coefficient were used. RESULTS: A total of 264 students aged 22.22±1.5 years were involved in the study. High stress levels occurred in 10% of the respondents. A statistically higher level of stress was revealed in people suffering from chronic diseases (p=0.006) and in cigarette smokers (p=0.004). The most common stress-coping strategies were active coping and planning. Insomnia was present in 19.7% of the students. Insomnia level was correlated with the intensity of perceived stress (p=0.00; r=0.44). CONCLUSIONS: According to our study, one tenth of Krakow students perceive a high level of stress, and one fifth of the respondents suffer from insomnia. There is a strong positive correlation between level of insomnia and level of stress. To ensure high quality of life, problems such as stress and insomnia should be taken into consideration by every general practitioner.
