The Relationship

Stress is a physical, mental, or emotional response to a change and is a significant problem in modern society. In addition to questionnaires, levels of stress may be assessed by monitoring physiological signals, such as via photoplethysmogram (PPG), electroencephalogram (EEG), electrocardiogram (ECG), electrodermal activity (EDA), facial expressions, and head and body movements. In our study, we attempted to find the relationship between the perceived stress level and physiological signals, such as heart rate (HR), head movements, and electrooculographic (EOG) signals. The perceived stress level was acquired by self-assessment questionnaires in which the participants marked their stress level before, during, and after performing a task. The heart rate was acquired with a finger pulse oximeter and the head movements (linear acceleration and angular velocity) and electrooculographic signals were recorded with JINS MEME ES_R smart glasses (JINS Holdings, Inc., Tokyo, Japan). We observed significant differences between the perceived stress level, heart rate, the power of linear acceleration, angular velocity, and EOG signals before performing the task and during the task. However, except for HR, these signals were poorly correlated with the perceived stress level acquired during the task.

The Relationship

The problems university students face during their education life often lead to undesirable situations as stress resources. Thus, various methods, techniques and strategies are employed in order to avoid negative effects of stress in their lives. Leisure is one of the effective methods in coping with stress, and leisure coping strategies are “leisure companionship”, “leisure palliative coping” and “leisure mood enhancement”. However, there are few studies in the literature focusing on the relationship between these strategies and perceived stress. Exploring this relationship is believed to provide valuable insights for university administrations so that they might offer effective recreation programs for their students. Therefore, this study aims to examine the relationship between perceived stress and leisure coping strategies. In addition, it examines whether there is a difference in perceived stress and strategies according to time spent for leisure activities and type of leisure participation. The participants of the study are 338 students, who were determined by using convenience sampling method. The data were collected through a survey that consists of three parts. The first part includes Perceived Stress Scale (PSS), the second one Leisure Coping Strategies Scale (LCSS) and the third one demographic questions about the participants. The data were analyzed by using Pearson Moment-Product correlation, t-test and ANOVA analyses. According to the findings, there is a negative significant relationship between perceived stress level, leisure coping strategies and its subdimensions. The study also found that perceived stress level of the participants who prefer passive participation in leisure activities is significantly different from that of those who prefer active participation. Similarly, the participants who prefer passive participation in leisure activities is significantly different from those who prefer active participation in terms of leisure coping strategies. In conclusion, the study contributes to the literature with these valuable findings and provides important insights for university campus recreation programs and services.

This study explored the immediate effects of Tai Chi (TC) training on attention and meditation, perceived stress level, heart rate, oxygen saturation level in blood, and palmar skin temperature in late middle-aged adults. Twenty TC practitioners and 20 nonpractitioners volunteered to join the study. After baseline measurements were taken, the TC group performed TC for 10 minutes while their cognitive states and cardiovascular responses were concurrently monitored. The control group rested for the same duration in a standing position. Both groups were then reassessed. The participants’ attention and meditation levels were measured using electroencephalography; stress levels were measured using Perceived Stress Scale; heart rate and blood oxygenation were measured using an oximeter; and palmar skin temperature was measured using an infrared thermometer. Attention level tended to increase during TC and dropped immediately thereafter (p<0.001). Perceived stress level decreased from baseline to posttest in exclusively the TC group (p=0.005). Heart rate increased during TC (p<0.001) and decreased thereafter (p=0.001). No significant group, time, or group-by-time interaction effects were found in the meditation level, palmar skin temperature, and blood oxygenation outcomes. While a 10-minute TC training could temporarily improve attention and decrease perceived stress levels, it could not improve meditation, palmar skin temperature, or blood oxygenation among late middle-aged adults.

Chronic stress is the main cause of health problems in high-risk jobs. Wearable sensors can become an ecologically valid method of stress level assessment in real-life applications. We sought to determine a non-invasive technique for objective stress monitoring. Data were collected from firefighters during 24-h shifts using sensor belts equipped with a dry-lead electrocardiograph (ECG) and a three-axial accelerometer. Levels of stress experienced during fire incidents were evaluated via a brief self-assessment questionnaire. Types of physical activity were distinguished basing on accelerometer readings, and heart rate variability (HRV) time series were segmented accordingly into corresponding fragments. Those segments were classified as stress/no-stress conditions. Receiver Operating Characteristic (ROC) analysis showed true positive classification as stress condition for 15% of incidents (while maintaining almost zero False Positive Rate), which parallels the amount of truly stressful incidents reported in the questionnaires. These results show a firm correspondence between the perceived stress level and physiological data. Psychophysiological measurements are reliable indicators of stress even in ecological settings and appear promising for chronic stress monitoring in high-risk jobs, such as firefighting.

Masticatory Muscle Activity

The aim of the study was to analyze the relationship between stress measured by the perceived stress scale (PSS-10) questionnaire and masticatory muscle activity. Experimental design assumed the study of healthy young women without temporomandibular disorders, dividing them into three groups depending on the result of the stress level and then comparing these groups in terms of bioelectrical activity of the masticatory muscles. After the exclusion criteria were applied, 63 female students (mean age: 22.3 ± 2.4 years) from Medical University of Lublin were included in the study. The subjects were then divided into 3 groups: with low (n = 18), medium (n = 18) and high stress level (n = 27), according to PSS-10 results. Resting and functional activity of temporalis anterior (TA) and masseter (MM) muscles were measured by electromyograph BioEMG III. There were statistically significant effects of group on the absolute value of asymmetry index (AsI) of TA and MM during maximum voluntary clenching on dental cotton rollers (both p = 0.02). Post hoc analysis shows that there were statistically significant differences between medium and high stress groups in AsI TA (p = 0.01) and between low and high stress groups in AsI MM (p = 0.02). Perceived stress measured by PSS-10 questionnaire seems to be associated with changes in muscular asymmetry in functional clenching activity.

Aim: The primary aim of this cross-sectional research study was to investigate the potential differences in perceived psychological stress level in those dieting compared to those not undertaking a diet. The secondary objective was to assess if stress levels in those dieting were correlated with the duration of the diet.Methods: We administered the previously validated Perceived Stress Scale (PSS) to 60 United Arab Emirates residents. Participants were also asked demographic questions concerning age and gender and were requested to indicate if they were currently undertaking a diet to achieve weight loss. Participants who were actively on a diet were also asked about the duration of the diet (days).Results: A total of 60 participants were recruited to the study, of which 71.7% were female. The majority (71.7%) of the sample were 18-25 years old and 58.3% indicated that they were undertaking a diet at the time of data acquisition. The median total score on the PSS was 19 (14 – 22). There was a significant difference in PSS total score between those on a diet and those not (p=0.021). A positive correlation was found between number of days on a diet and perceived stress level (r=0.147) but this was not statistically significant (p=0.406).Conclusions: Dieting behaviour was associated with higher levels of perceived psychological stress compared to those not undertaking a diet. Engaging in dieting behaviour is commonly driven by body dissatisfaction and may be linked to heightened stress due to social pressures or other factors.

The Relationship

Background and aims: Nowadays, with the advancement of science and technology, lifestyle has changed and fast foods are being commonly consumed. Due to their special circumstances, university students are susceptible to stress, anxiety, and bad nutritional patterns and, because of the consumption of high amounts of fat and salt and physical inactivity, are at increased risk of overweight and obesity. Therefore, the present research was conducted to study the relationship between the consumption of fast foods and perceived stress level among female students of Shahrekord University of Medical Sciences. Methods: The present research was a descriptive-analytical study conducted on female students of different faculties and majors in Shahrekord University of Medical Sciences in the academic year 2016-2017. From the study population, 152 students were selected as the samples using random cluster sampling method. Data were collected using a demographic information questionnaire (age, major, parents’ education level, education level, and place of residence), a standard 14-item scale for the measurement of perceived stress level, and a checklist to record the frequency of fast foods consumption in university and home or dormitory (daily, weekly, and monthly). Data analysis was conducted using descriptive and analytical tests (chi-squared, independent t test, and Spearman’s and Pearson’s correlation coefficients) in SPSS 18. Participation in the study was voluntary. Results: Results showed 45.4% of participants aged 18-20, 16.4% of whom were studying in public health, and 85.8% were BSc students. The mean scores of perceived stress and fast foods consumption were 51.36±13.52 and 12.42±5.42, respectively. There was a significant relationship between age and perceived stress (P=0.000), and between mother’s education level and perceived stress (P=0.011). There was no significant relationship between the mean score of perceived stress and fast foods consumption in participants (P=0.072) Conclusion: Considering the level of perceived stress and fast foods consumption in university students, it is necessary to apply effective patterns and theories of health education and promotion and also to direct attention to interpersonal and environmental factors to reduce stress and encourage healthy eating habits.
