The Role of body image, disordered eating and lifestyle on the quality of life in Lithuanian university students
ENPurpose. The present study aimed to explore the associations between body image concerns (BI), disordered eating (DE), health-related lifestyle, and the different domains of the quality of life (QoL) in a Lithuanian sample of student-aged men and women. Methods. A mixed-gender sample of students (N = 1850, 58.8% were women, average age 21.6 ± 5.0 years) completed a series of questionnaires, including health-related lifestyles, BI, DE, and QoL. A series of simultaneous multiple linear regression analyses were conducted. Mediation analyses were performed to estimate the size of the total, direct, and indirect effects of variables in the models. Results. The analysis of the linear regressions demonstrated that the positive trait of body areas satisfaction was associated with the significantly enhanced QoL in all domains in both genders (for men β = 0.29–0.34; for women β = 0.26–0.33; p <0.001). DE was associated with a poorer psychological QoL domain in women only (β = −0.07; p = 0.047). The drive for muscularity was associated with a lower QoL in men (β = −0.06–(−0.141); p <0.05). Body areas satisfaction mediated the associations between body mass index and psychological and physical QoL in both genders (TLI (Tucker Lewis Index) = 0.975; CFI (comparative fit index) = 0.997; RMSEA (Root of the Mean Square Error) = 0.053). Conclusions. Positive traits of BI play essential roles in the QoL of student-aged women and men. The present study adds empirical evidence emphasizing the importance of integrating education about positive body image while implementing healthy lifestyle and QoL promotion programs in student-aged men and women.
