Purpose. This study aims to examine the relationship between physical activity, eating attitude, and bigorexia nervosa among university students. Method. A questionnaire form consisting of sociodemographic characteristics, eating habits, the Eating Attitude Scale (EAT-40), the International Physical Activity Questionnaire (IPAQ), and the Muscle Appearance Satisfaction Scale (MASS) was conducted on undergraduate students at Üsküdar University. Results. There were 1006 students who participated in this study with a mean age of 22.58 ± 2.87 years. The median “muscle appearance satisfaction” score of the obese students was statistically higher than the normal weight and underweight students. The median score for “Obesity Anxiety” was statistically higher in underweight students than in obese ones. A one-unit increase in IPAQ scores was related to an elevation of 24.9% in the MASS and a decrease of 17.9% in the EAT-40 scores, while a one-unit increase in MASS scores was related to a reduction of 12.5% in the EAT-40 scores. Conclusion. Eating attitude is associated with bigorexia nervosa, and as MASS scores increase, EAT-40 scores decrease and as IPAQ scores increase, and EAT-40 scores decrease. In other words, as physical activity increases, muscle strength satisfaction elevates, and in parallel with this increase, a positive eating attitude improves.

Background: Emotion regulation challenges may be a general risk factor for disordered eating habits, and particularly during the university period, which entails processes such as young people moving away from their families and adjusting to new environments. This study examined the effect of difficulty in emotion regulation on eating attitudes and body mass index (BMI) in university students. Methods: A questionnaire form including questions about sociodemographic characteristics, questions about eating habits, the Difficulty in Emotion Regulation Scale (DERS-16), and the Eating Attitudes Test-40 (EAT-40) was administered to 750 undergraduate students at Üsküdar University. Data were analyzed with IBM SPSS Statistics 26. Results: Of the 750 students participating in this study, 47% were male and 53% were female. The average BMI of the students was 22.43 (20.44-24.80) kg/m 2 . There was a statistically significant positive and very weak correlation (s = 0.179; p < 0.001) between DERS-16 scores and BMI values, and an increase of 18% was found in DERS-16 scores as BMI values increased. There was also a statistically significant and very weak correlation (s = 0.174; p < 0.001) between the students' EAT-40 scores and BMI values, and an increase of 17% was found in EAT-40 scores as students' BMI values increased. Students' BMI values were significantly correlated with DERS-16 scores (R 2 = 0.033; F = 25.324; p < 0.001) and a one-point increase in the DERS-16 score resulted in a 4% increase in BMI. It was found that as the DERS-16 total score increased, there was a decrease in obesity anxiety, preoccupation with thinness and EAT-40 Total score (respectively 10.9%, 14.4%, 7.3%). Conclusions: Difficulties in emotion regulation may be correlated with BMI and eating attitude.

The aim of this study was to examine the effect of chronotype on addictive eating behavior and BMI in university students. A questionnaire on their sociodemographic characteristics and eating habits, as well as the three-factor eating questionnaire (TFEQ) and the morningness-eveningness questionnaire (MEQ), were given to students at Üsküdar University. Data were analyzed with IBM SPSS 26.0. This study included a total of 850 students, 46.8% of whom were male and 53.2% were female. The mean BMI was 22.94 ± 3.30 kg/m2. As the BMI values of students increased, there was a decrease of 25.6% in the TFEQ scores, regardless of gender (s = −0.256; p < 0.001), and an increase of 10.6% in their chronotype scores, meaning that the students tended to be morning types (s = 0.106; p < 0.01). A significantly negative, very weak correlation was found between the students’ TFEQ and MEQ scores (s = −0.123; p < 0.001). The students’ BMI (p < 0.01) and TFEQ scores (p < 0.001) were affected by their MEQ scores in a statistically significant way. It was found that each 1-point increase in the MEQ score led to a 4.0% increase in the BMI score and a 15.8% decrease in the TFEQ score. It was observed that the morning-type students tended to be obese in terms of their BMI, and these students demonstrated fewer addictive eating behaviors.
