The morbid obesity group had significantly higher rates of current BED (25.0%) and night eating syndrome (27.5%) diagnoses, as assessed by the DSM-5 criteria (p < 0.001). The total and sub-scale scores of the EDEQ were not normally distributed. A Kruskal-Wallis assessment revealed that the total and sub-scale scores of different BMI categories differed significantly, showing that higher BMI was associated with higher EDEQ scores. When the FA and non-FA groups were compared, FA was significantly associated with more severe eating symptomatology as assessed by EDEQ (Table 5).

When morbid obesity, FA, and BED diagnoses were examined together, although comorbidities were present, the majority of FA diagnoses (75%) did not meet the diagnostic criteria for BED. In the morbid obesity group, 22.5% had both FA and BED diagnoses. The comorbid group differed from the FA-only group with greater tolerance (? 2 = 6.10, p = 0.01), failure to fulfill major role obligations (? 2 = 9.93, p < 0.01), and higher attentional impulsivity scores (z = ?2.08, p = 0.04). On the other hand, the FA-only group differentiated from the comorbid FA and BED group, as they met the two following BED criteria significantly less frequently: (i) repetitive binge eating episodes and a sense of lack of control over eating during the episode, and (ii) feeling disgusted with oneself, depressed, or very guilty after overeating (p = 0.02, p = 0.06, respectively).

Finally, a logistic regression was performed to ascertain the effects of age, gender, sociodemographic characteristics, eating disorders and impulsivity on the likelihood that participants had FA. The logistic regression model was statistically significant, [? ( 11 ) 2 = , p < 0.05]. The model explained 45.7% (Nagelkerke R 2 ) of the variance in FA. Women were 6.7 times more likely to exhibit FA than men. The presence of BED (OR: 8.33 %95CI [1.96–]; p < 0.05) and higher BIS-11 scores (OR = 1.09 %95CI [1.02–1.23]; p = 0.03) independently predicted the diagnosis of FA.

Discussion

In such a case-manage investigation assessing the latest the total amount off and you may related issues that have FA in different Body mass index groups, it was learned that FA is actually in the a higher Body mass index, an early on start of diet and more frequent diet-putting on weight time periods; including highest attentional and you may engine impulsivity. Furthermore, brand new FA danger signal matter are certainly correlated that have Bmi. The results recommend that FA you’ll enjoy a crucial role for the being obese, using death of control of dinner use inside the an addictive trends. Hence, treating FA would be a useful method with respect to lbs losings.

The brand new Incidence from FA Having fun with DSM-IV and you may DSM-5 Techniques

The latest frequency regarding FA about morbid obesity classification given that analyzed because of the YFAS (fifteen.0%) is comparable with that in two knowledge in the arena, in which fifteen and you may sixteen.9% regarding bariatric functions mobifriends applicants was basically diagnosed with FA (45, 46). Although not, there are many more knowledge conducted among people undergoing weight-losses businesses where large costs instance 21.1% (47), twenty five.8% (48), 41.7% (49), 53.7% (50), 57.8 (38) had been located. This large adaptation might possibly be as a result of the thinking-report character out of YFAS, that is less-purpose than a standardized scientific comparison hence our try had less imply Bmi as compared to the second studies. It is known you to definitely DSM-IV substance reliance diagnosis represents major material have fun with illness regarding new DSM-5 (51). With all this, the brand new incidence of FA on morbid carrying excess fat group appears to end up being 40.0%, implying you to definitely DSM-5 conditions might possibly be even more permissive in terms of choosing FA, while YFAS you’ll overlook some cases. Also, once the YFAS, which is in accordance with the DSM-IV material dependency requirements does not include craving, which can subscribe below real costs.
