Background and Aim: In recent years great emphasis has been put on the importance of a healthy lifestyle. This study aimed to assess the lifestyle of high school and pre-university students in Bandar-Abbas, Iran.

  Materials and Methods: Using a multistage sampling method a total of 410 high school and pre-university students in Bandar-Abbas, Iran were selected. To assess the lifestyle of the students the Adolescent Health Promotion Scale was used. This 40-item scale assesses six health-promoting behaviors, including those related to nutrition, social support, personal responsibility, health valuation, physical activity, and stress management.

  Results: The mean age of the students (49.8% males and 50.2% females) was

  16.5 (SD=1.34) years. The data showed the mean score of the total scale to be 64.89 out of 100. The mean scores (out of 100) of the subscales of nutrition, social support, personal responsibility, health valuation, physical activity and stress management were 71.06, 63.00, 63.12, 82.11, 41.49, and 68.58, respectively.

  Conclusions: The findings of this study reveal that the health-promoting behaviors of high school students living in Bandar-Abbas are not, on the whole, desirable. The regular physical activity subscale had the least score, which shows that a sedentary lifestyle is a common, serious problem among thestudents.
