Introduction: Health is also particularly important in flights. The current study aimed to investigate the determinants of health behaviors among travelers of Shiraz Shahid Dastghaib International Airport based on Health Belief Model.
Methods: In this descriptive-analytic cross-sectional study, 349 air passengers were investigated at Shiraz International Airport using non-probability method. A researcher-made structured questionnaire was used to collect data. Validity and reliability of this questionnaire were at optimal level. Data were later analyzed by SPSS software and appropriate statistical tests were performed including descriptive statistics, spearman correlation coefficient, and linear regression.
Results: The mean and standard deviation of health behavior total scores was 8.20±5.65. Among the constructs, the highest and the lowest scores were related to  perceived benefits and cues to action, respectively. Health behavior had a significant relation with perceived susceptibility, perceived severity, perceived benefits, perceived barriers, self-efficacy, and cues to action (p<0.01). Perceived benefits, perceived barriers, self-efficacy, and cues to action explained health behavior. Furthermore, the perceived benefits (β=0.25, P=0.001) had the most and perceived sensitivity (β=0.32, P=0.56) had the least explanatory.
Conclusion: Health behaviors among air travelers were in undesirable condition. Thus, intervention programs are recommended to improve these behaviors. Since in recent study, the perceived benefits had the most explanatory power, health professionals should use the changing behavior strategy in interventions.
