Objectives: This paper aimed to examine the association between chest deformities and symptoms of depression and anxiety in a population of young individuals. Study Design: A cross-sectional study. Participants and Methods: The study included 100 participants and was conducted from January to the end of May 2024 using a questionnaire consisting of three parts: a section with general and sociodemographic data, the PHQ-9 Patient Health Questionnaire for assessing depression, and the GAD-7 scale for assessing anxiety. Results: Data from 100 participants were statistically analyzed. The average age of the participants was 14.6 years. Fifty-one participants attended primary school, forty-seven attended high school, and two were in college. Among the participants, 88% had scoliosis, 10% had hyperkyphosis, and 2% had pectus excavatum. The average depression score of all participants was 5.33 ± 4.19, which falls into the mild depression category. The average anxiety score was 4.26 ± 3.81, corresponding to normal to mild anxiety levels. There was a positive correlation between depression and anxiety. A significantly higher number of female participants showed signs of anxiety and depression compared to male participants. There was a significant statistical difference between younger and older participants; older participants had higher levels of depression, while there was no age-related difference in anxiety levels. There was no difference in anxiety and depression levels among participants with different diagnoses. There was no statistically significant difference in anxiety and depression according to the severity of deformity. Conclusion: Young individuals with chest deformities exhibited mild to moderate levels of anxiety and depression. Female participants had higher levels of these psychological conditions. Additionally, older participants had significantly higher levels of depression. There was no difference in the level of depression and anxiety concerning the severity of the deformity.
