The findings of the current research demonstrated that among the four components that were assumed to contribute to absenteeism, professors' performance and the issues pertaining to educational planning had the most significant effects on the students' absenteeism, while the students' personal and family issues had the least significant impact on their absenteeism. The majority of the students believed that they could only learn within the first 30 minutes of the class time and envisaged an average professional future. In addition, they admitted to the fact that their interest in their field of study had declined sharply compared to the time of university admission, and they did not feel the need to attend classes for learning, which further emphasized their diminished interest in attending general courses. The students also considered the professors' competence and presentation skills to be the most significant influential factors in the quality of teachers' performance. They also stated that their families were hardly aware of their academic status at the university, expressing no interest in attending the classes on the first two days of the week at 8-10 in the morning of all the weekdays. Consistently, Nabavi et al. investigated the contributing factors to the absenteeism of medical students in Tehran (Iran), reporting that among the four components of absenteeism, professors’ performance and educational planning problems were the most significant factors (

In a similar study, Wadesango et al. evaluated the causes of students' absence and the consequences in South African countries, and the findings indicated that the students' disinterest in the lessons, inappropriate teaching strategies, unsuitable learning environment, students' part-time employment, and poor interactions with the professors were the main reasons behind the students' absenteeism. In addition, the mentioned study showed an indirect, negative correlation between the students' absence and their academic performance (

The results of the study by Vakili et al. on medical students indicated that 39% of the students cut their class for two hours per each credit of the course, while 22.4% of the students were absent for four hours per each credit of the course, and 38.6% stated that they would never cut the classes, except in emergency situations. In the mentioned research, the students viewed inappropriate teaching methods, lack of sound sleep during the night and its concomitant fatigue and tiredness, and issues of professors’ presentation skills as the most important factors involved in their absenteeism, while disinterest in the field of study was considered to be the least significant contributing factor in this regard (

The findings of a study by Hughes revealed the main causes of students' absence in classes to be family problems, appointments with doctors/dentists, disinterest in lessons, and avoidance of assignment submission (
11). Among the other influential factors in student absenteeism in the literature are teaching methods, professors' self-confidence, uselessness of the materials presented in classes, low academic level of classes, traditional classroom management, students' non-participation in class activities, and professors' inattention to the attendance of students (

9-
12).
Contrary to the results of the present study, the study by Hughes et al., which was conducted in the United Kingdom on sophomore nursing students, indicated that the main reasons for students' absence were family issues, appointments with doctors/dentists, disinterest in the subject, and absence/indifference at the time of assignment (
11). Furthermore, the research by Jortof et al., which was performed on pharmacy students at the University of Chicago, demonstrated the main reasons for absenteeism to be the low academic level of classes, commuting between the university and home, no presentation of new materials, adherence of professors to textbooks/pamphlets, and class size (
13).
Professors could lead students to high aspirations or deprive them of achieving their goals with the appropriate and innovative combination of the elements of the educational system. Therefore, they play a pivotal role in motivating students to attend classes. The conflicting results of the present study with the previous findings in this regard could be due to the differences in the research community, geographical areas, and educational systems.
Our findings indicated significant correlations between the status of medical education as a contributing factor to absenteeism and the variables of age, marital status, and housing occupancy status. Furthermore, such correlations were observed between the personal and family issues of the students (absenteeism component) and marital status, as well as the issues pertaining to the professors' performance and students' grade point average. In this regard, the results obtained by Azmoudeh et al. showed a significant difference between the two genders in terms of the characteristics of the teacher, environment, and students. The field and degree of education were also reported to have significant associations with the influential factors in student attendance (
6). Karami et al. also observed significant correlations between the influential factors in the attendance of students and gender variable, as well as the influential factors in their absenteeism and educational degree (
7).
The results of the present study could be justified by the fact that the married students and those of the older age often have a broader, more realistic and forward-looking view, which lead them to pay closer attention to their field of study and its career prospects in the future. As such, the correlations between the status of medical education, age, and marital status could be confirmed as married students have more concerns and family issues. We also observed a correlation between the component of personal and family issues and marital status of the students.
Considering that students with a higher GPA put more effort into learning and obtaining higher grades, they also pay more attention to the classes and applied teaching methods, which justifies the association between the issues pertaining to the professors' performance with the GPA of the students in the present study. The discrepancies between the findings in this regard could be attributed to the differences in the influential factors in absenteeism, as well as the research tools and variables.
One of the limitations of our study was the data collection instrument, which was a questionnaire; the students’ problems and causes of absenteeism could have been more comprehensively identified and better solutions could have been put forward if interviews with open-ended questions had been used instead. Therefore, it is suggested that qualitative studies be designed and conducted in the future.
5.1. Conclusion
According to the results, student absenteeism may have multiple causes, while the most important factors were observed to be the issues associated with the performance of the professors in the viewpoint of the students. Therefore, special attention should be paid to this aspect, and it is recommended that professors, educational planners, and policymakers consider the mentioned factors as the main causes of students' absenteeism, so that students would become more willing to attend educational environments and the teaching-learning process would be promoted. Furthermore, free discussion sessions could be implemented to let students freely express their problems, and motivational classes could help solve these problems and motivate students.
