Abstract

Nursing students tend to overuse smartphones, and when this is combined with psychological issues, it often disrupts their sleep patterns. This study aimed to investigate the correlation of smartphone overuse, psychological problems, sleep quality, and daytime sleepiness among professional nursing students. Descriptive correlational and cross sectional design were employed. The samples were recruited using convenience sampling technique involving 110 students. The questionnaires were Smartphone Addiction Scale-Short Version (SAS-SV), Depression, Anxiety Stress Scale-42 (DASS-42), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS).  Pearson correlation was utilized to examine the correlation between study variables. Majority of students were addicted to smartphone (65.5%), poor sleepers (78.2%), and had excessive daytime sleepiness (EDS) (54.5%). Sleep quality was negatively correlated to depression (r=-0.335, p<0.001), anxiety (r=-0.333, p<0.001), and stress (r=0.331, p<0.001). EDS had correlation with smartphone overuse (r=0.315, p=0.001), depression (r=0.252, p=0.008), anxiety (r=0.288, p=0.002), dan stress (r=0.216, p=0.024). Participants with poorer psychological problrmes were trying to manage their sleep quality to be better, even though still experienced EDS. Future studies could investigate the factors contributing to excessive smartphone use, psychological influences, and other elements impacting sleep, while also incorporating more objective methods to improve data precision.

Abstract

Poor sleep quality among university students is often associated with academic stress, lifestyle habits, and irregular routines, which may influence blood pressure (BP). This study aimed to examine the relationship between sleep quality and BP in Indonesian university students. A descriptive correlational study with a cross-sectional design was conducted among 207 students at a private university in North Sulawesi Province of Indonesia. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) and BP was measured with an aneroid sphygmomanometer. Data analysis included descriptive statistics and Spearman correlation. The mean sleep quality score was 8.50 (SD=3.51) and 84.1% of participants were classified as having poor sleep quality. The mean systolic and diastolic BP were 107.76 mmHg (SD=13.61) and 75.91 mmHg (SD=11.91), respectively. A significant but weak negative correlation was observed between sleep quality and systolic BP (r=-0.191, p=0.006). While these findings differ from much of the global evidence linking poor sleep to higher BP, they highlight the complexity of sleep-BP interactions in young and healthy populations. These findings emphasize the importance of promoting better sleep hygiene, healthier lifestyle behaviors, and cardiovascular health strategies within university settings.
