Abstract
Aim of the study:
This study conducted to assess the prevalence of different health problems facing university students (poor health behavior, depression, anxiety, stress, internet addiction, poor sleep quality, overweight/obesity and smoing) and their influencing factors.
Research methodology:
This study is a descriptive cross-sectional study, included 714 students; (426 from Faculty of Medicine and 288 from faculty of Arts and social sciences) during the period from November 2019 to December 2020.
Data were collected from participants after explaining the nature of the study and taking a verbal consent from each of them. Approval of the dean of each college, the vice dean of student affairs and the ethics committee is taken.
A well structured aided questionnaire was designed to assess the different health problems. The questionnaire included:
• Demographic characteristics of students (age, gender, type of college, study grade, nationality, residence status, number of home visit, and housing problems and smoking history).
• The Health-promoting Lifestyle Profile II (HPLP 2)
• Depression, Anxiety. Stress Scale 21 (DASS 21)
• Internet addiction test (IAT)
• The Pittsburgh Sleep Quality Index (PSQI)
• Physical measurements (weight – height – body mass index)
Results:
The overall mean health promoting behavior score in all studied students was (2.33 ± 0.39), this mean poor health behavior response (<2.5 poor response), with higher interpersonal relation and spiritual growth score. University resident students had a lower health behavior score but urban students and those studying at practical faculties had a higher health score. Students with depression were about 4.38 times, more likely to have a negative health promoting behavior response.
There was high percentage of depression (70.2%), anxiety (66.2%) and stress (52.7%) among all studied students. Depression, anxiety and stress scores (DASS) were higher among non-resident than university or private resident students. Female, rural and theoretical faculty students had higher DASS score than other counterparts, Fourth grade students had higher depression and stress than first grade students. Internet addiction, poor sleep quality, stress and higher body mass index were significantly associated with depression and anxiety.
The mean internet addiction score was (49.65 ± 20.13), with about (45.2%) frequent and occasional problematic internet addiction. Internet addiction score was higher among private residents (50.39 ± 19.64) than non-residents or university resident students. fourth grade male urban students had a significant higher internet addiction score than first grade female rural students, Poor sleep quality, depression and anxiety were significantly associated with internet addiction among studied students.
Sleep quality index was high among all students (8.34 ± 3.34), this indicated poor sleep quality, private resident students experienced the highest index (8.55 ± 3.42). Internet addiction, depression and anxiety were significantly associated with poor sleep quality among studied students.
There were high percentage of overweight and obesity among university students (35.9%), the percentage of overweight was more among university resident students (32%), however, obesity was more in private residents. body mass index was significantly higher in urban and fourth grade students. Depression was significantly associated with body mass index ≥ 25 among studied students.
Smoking prevalence was very low among studied students (2.8%)
Recommendations:
1. Health promoting behavior programs should be regularly organized within colleges, generating an encauraging ennironment for adoption of good healthy behaviors and healthy lifestyles.
2. More emphasis should be directed toward university residence, encouraging the student to practice better and healthy life style inside residence halls, highly experienced public health teams should visit residence regularly, check on health facilities, served diet, health status and satisfaction and needs of resident students.
3. There is need for universal screening for depression in colleges and interventions to improve mental health and wellness. Counseling and preventive mental health services should be an essential part of the routine investigation of medical students.
4. It is necessary to develop strategies for prevention of internet addiction as well as therapeutic interventions to enhance the safe and healthy use of the Internet.
5. Awareness should be created among the undergraduate students about the disadvantages of the excessive use of the internet and encouraging students to use the internet for academic researches and gathering scientific information.
6. All college students should be given an interactive awareness session on importance of sleep in student life and academic performance and the criteria of good sleep quality and alarming signs of poor sleep.
7. Regular screening of sleeping problems and associated factors among resident students is nessesary to identity the students at risk and housing factors related to these problems, so measures are taken for adjustment of housing environment.
8. Organization of frequent anti-tobacco campaigns in universities and public places with involvement of the students as educators.
