Background and Objectives: The prevalence of mental health disorders and risky behaviors among the population is increasing, especially young people. Some groups, such as students, are more likely to suffer from mental health problems and risky behaviors.Risky behaviors are among the most important factors endangering the health of communities.The present study aimed to evaluate mental health and risky behaviors among students of Kashan University of Medical Sciences. Materials and Methods:The current research is a descriptive, cross-sectional study. 400 students of Kashan University of Medical Sciences were selected. After receiving demographic information, the participants' mental health (SCL-90) and risk behaviors were measured. Then, the data were analyzed and examined using SPSS version 17 software and statistical methods (variance analysis and Pearson's correlation coefficient test). Results:The average age of the participants was 22.46±2.98 years, with 243 individuals (63.8%) being women. 55.6 percent of the participating students had symptoms of psychiatric disorder based on the total mental health score.Also, the level of tendency to risky behaviors in the participating students was low (average percentage less than 50).In general all mental health components have a significant relationship with tendency to risky behaviors (p<0.001, r=0.376) except the component of sensitivity in interpersonal relationships, alcohol and cigarettes and the component of fear with tendency to have relationships with the opposite sex. Conclusion:In general, the results of the study indicate that mental health plays an effective role in students' risky behaviors;therefore, planning to increase students' mental health and increase their awareness in the field of emotion management, life skills, and mental health can probably play a significant role in reducing risky behaviors.Therefore, given the importance of mental health and risky behaviors in society, it is necessary to conduct more studies in this field.
