This cross-sectional study conducted in Poland explored the relationship between the fear of negative appearance evaluations, eating disorders, and physical activity objectives, particularly during the COVID-19 pandemic. The Fear of Negative Appearance Evaluation Scale (FNAES), the Eating Attitude Test (EAT-26), and the Physical Activity Goals Inventory (IPAO) were administered to 644 participants (455 males with a mean age of 35.2 ± 6.2 years and 189 females with a mean age of 30.18 ± 5.7 years). This study explored the effects of gender, age, and body mass index (BMI) on FNAES, EAT-26, and IPAO scores. The results of this study demonstrated that females scored higher on fear of negative appearance, peaking at 41-50 years of age. Distinct BMI categories were associated with different negative appearance fear scores, eating attitudes, and physical activity objectives. Significant correlations were also found between the fear of negative appearance, dietary attitudes, and physical activity goals. Eating attitudes completely moderated the relationship between the fear of negative appearance and physical activity objectives. A significant interaction effect of age and body mass index on physical activity objectives was also revealed. These results highlight the relevance of considering gender, age, and body mass index when examining the associations between the fear of negative appearance, eating attitudes, and physical activity objectives.

Body dissatisfaction (BD) is central to the development, maintenance and relapse of anorexia nervosa (AN). BD has been conceptualized as a multi-dimensional construct incorporating behaviours, cognitions and affect, yet little is known about the impact of weight and disordered eating on these aspects. 56 \'below DSM-IV weight criteria for AN\' (BMI 17.5 kg/m(2)) individuals currently receiving treatment for an eating disorder, and 60 non-eating disordered females completed the Body Checking Scale, Body Image Avoidance Questionnaire and the Body Image Anxiety Questionnaire. As expected, females diagnosed with AN showed significantly more behavioural and affective body dissatisfaction than the control group. Patients at lower weights showed significantly more avoidance behaviours and less body image anxiety than those with anorexia at higher weights. No difference was seen in checking behaviours between these groups. Weight based differences in avoidance behaviours continued to exist even when the effects of anxiety were controlled for. Affective and behavioural aspects of BD should be considered in clinical practice at all stages of treatment.
