Background & Objective: The most common disorders in psychiatry are anxiety disorder. The onset is from adolescence through early adulthood. Some people due to various reasons are susceptible to these disorders, such as airport tower’s controller. This study was done in order to determine anxiety level and its relationship with some variables such as age, length of employment, gender, education, marital status, cigarette consumption, physical training and employment satisfaction. Materials & Methods: This was a cross-sectional descriptive analytical study, which was performed on all of the controller personals (101 samples) during spring 2003, at Tehran Mehrabad Airport, control towers controllers. They were studied by using an anxiety questionnaire. The relationship between anxiety level was determined by 8 independent variables. Results: The findings from this study indicated the following results: Undetectable minor anxiety (22.8%), mild intermediate anxiety (52.5%) and high-very high anxiety (24.8%). Conclusion: According to the results from this study. The employment satisfaction could play an important role, in preventing the anxiety. In this sensitive job, the personal attention and concentration is of upmost importance, any factor that disrupts, this concentration should be prevented, otherwise unwanted accidents may happen. Therefore it is suggested that the responsible authorities select, the appropriate persons and provide them with a good and satisfactory job conditions to pave the way for the up grading the level of immunity in air flight.

Background and Objective: Aircraft as a safe means of transportation may cause occupational diseases and hearing loss. Prevention should be implemented for airport employee. This study was done to detemine the scale of hearing loss among Isfahan airport employees in 2005. Materials and Methods: This historical cohort study was conducted among Isfahan International airport employees. 80 employees were selected in four different case groups, the control group consist of two sub-gourps. The sub-group I (18 subjects) including the adminstrative airport employees (low noise exposed) and the sub-group II (32 subjects) including non-airport employees (non-noise exposed). The sound pressure level was measured and equivalent level (Leq) was calculated for all groups. Also the history of participants about past noise exposure and other confounding variables was detrmined by a questionnaire. Pure tone audiometry was carried out on conventional frequencies (0.5-8 KHz). Results: The mean age of subjects was 40.03±9.75 and 37.85±8.15 for exposed and non-exposed groups respectively. Leq (noise equivalent level) for Ramp and traffic workers was estimated more than 95 dBA. 35.7% (n=10) of Ramp workers were suffering in their right ear from noise induced hearing loss (26-40dB) and 32.1% (n=9) of them in their left ear. Relative risks of noise induced hearing loss in Ramp workers in comparison with control group were 9.4 and 7.5 for right and left ears. A siginificant difference was found between the hearing thresholds of exposed and non-exposed groups (P<0.05). Conclusion: This study showed that occupational exposure to noise cause hearing loss among airport employee. It is suggested strategies of noise assessment and prevention should be implemented for airport employees.
