Sažetak
Purpose: Orthorexia nervosa (ON) is an eating behavior where patients obsessively try to reach health through purity of food. Narcissism is a personality trait characterized with the self- belief of grandiosity, importance and need of appreciation. Both of these conditions are connected through self-image in way of reaching perfection through health and body image, whereas one of the ways for reaching it is exercising. This cross-sectional study aimed to investigate ON and its possible association with narcissism in fitness center users. Methods: The study included 1017 fitness center users and three questionnaires were used for the assessment: general information, ORTO-R and Narcissistic personality inventory-13 (NPI-13). Results: There was a significant negative correlation (r = - 0.467, p < 0.001) between the ORTO-R score and the NPI-13 score. Comparison of the ORTO-R score between different durations of using a fitness center showed statistically significant differences (H = 134.72, p < 0.001). The subjects who are using the fitness center for less than 1 year have the highest ORTO- R score, while those who are using it 1-3 years have the lowest ORTO-R score. Moreover, multiple linear regression showed that ORTO-R score retained significant association with NPI-13 (beta +/- SE, - 0.416 +/- 0.026, p < 0.001) and the duration of using a fitness center (0.576 +/- 0.068, p < 0.001) after model adjustment for age and BMI. Conclusion: These results are implying that fitness center users could possibly be vulnerable of developing ON and that there is a strong association between ON and narcissism in this population. However, future larger-scale longitudinal studies are needed to address these findings.
