To examine the exercise behavior of 953 Turkish University students (496 men, 457 women) by sex, residence, and department of study, a stratified sampling method, based on the total number of students in each department, was used to select participants. The mean age of the participants was 21.3 yr. (SD = 1.9). For completed Physical Activity Stages of Change Questionnaire and the International Physical Activity Questionnaire, descriptive statistics and chi-squared tests indicated that most Students were at the lower stages of change in exercise habits: Precontemplation (15.2%), Contemplation (31.4%), and Preparation (25.3%), compared with the later stages of Action (75%) and Maintenance (20.6%). Women and students from the Department of Architecture were at lower stages of change than men and Students from other departments (p<.05), but there were no significant differences between students who were living on or off campus. Stage-based interventions Would be appropriate, with focus on the physical activity of women and students in architecture.
