Characteristic relationships between personality traits in healthy people were analysed, but little is known about the relationships assessment between personality traits in obesity patients with OSA, which may be important in the diagnosis of these patients.The aim of the study was to assess the correlation between personality dimensions in patients with OBS qualified for bariatric surgery.59 patients with II and III obesity, including 12 patients with OSA were exanimated. The study was conducted using the NEO-FFI questionnaire, the Epworth scale and the STOP-Bang questionnaire.We observed significant positive correlations between such personality traits as: conscientiousness and agreeableness (r= 0.416, p< 0.05), conscientiousness and extraversion (r= 0.530, p< 0.05) and agreeableness and extraversion (r= 0.502, p< 0.05) in patients with obesity and without OSA. A significant negative correlations were observed between such personality traits as: neuroticism and conscientiousness (r= -0.601, p< 0.05), neuroticism and agreeableness (r= -0.509, p< 0.05) and neuroticism and extraversion (r= - 0.651, p< 0.05). Interestingly, such relationships were not observed in obesity people with OSA.Psychological analysis in patients with obesity showed the existence of characteristic relationships between personality traits, consistent with literature data. In patients with OSA, these typical relationships in personality dimensions were not observed, which may indicate the existence of significant psychological determinants in the biology of this disease.FootnotesCite this article as: European Respiratory Journal 2023; 62: Suppl. 67, PA3827.This abstract was presented at the 2023 ERS International Congress, in session “Inflammatory endotyping: the macrophage across disease areas”.This is an ERS International Congress abstract.
