- Purpose Anorexia nervosa (AN) is an eating disorder characterized by low fat mass complicated by osteoporosis. The role of circulating vitamin D in the development of bone loss in AN is unclear. Fat mass is known to be inversely associated with vitamin D levels measured as serum levels of total, protein-bound 25-hydroxyvitamin D, but the importance of directly measured, free levels of 25(OH)D has not been determined in AN. The aim of this study was to investigate vitamin D status, as assessed by serum concentrations of total and free serum 25(OH)D in patients with AN and healthy controls. Methods In female AN patients (n = 20), and healthy female controls (n = 78), total 25(OH)D was measured by LC-MS/MS, and free 25(OH)D with ELISA. In patients with AN bone mineral density (BMD) was determined with DEXA. Results There were no differences between patients and controls in total or free S-25(OH)D levels (80 +/- 31 vs 72 +/- 18 nmol/L, and 6.5 +/- 2.5 vs 5.6 +/- 1.8 pg/ml, respectively), and no association to BMD was found. In the entire group of patients and controls, both vitamin D parameters correlated with BMI, leptin, and PTH. Conclusions The current study did not demonstrate a vitamin D deficiency in patients with AN and our data does not support vitamin D deficiency as a contributing factor to bone loss in AN. Instead, we observed a trend toward higher vitamin D levels in AN subjects compared to controls. Measurement of free vitamin D levels did not contribute to additional information.

- Adolescence has been considered a critical time for the development of body image-related difficulties and disordered eating behaviours, especially in females. Although adherence to eating rules has been linked to disordered eating, literature has not yet explored how the inflexible subscription to those rules impacts on eating psychopathology. Therefore, the aim of the current study was to explore whether inflexible eating impacts on the relationships between weight and body image-related variables, and disordered eating.Participated in this study are 497 female adolescents from the community, aged between 14 and 18 years old, who completed self-report measures.Results revealed that the majority of the participants were dissatisfied with their weight and body shape. Moreover, 6.64 % of the participants demonstrated severe eating psychopathology. A path analysis revealed that BMI, body dissatisfaction and social comparisons based on physical appearance impact on disordered eating behaviours, through the mechanism of inflexible adherence to eating rules. This model explained 52 % of eating psychopathology's variance.Findings highlight the relevance of body image-related difficulties in adolescence and additionally they emphasise the importance of promoting more flexible attitudes towards eating in prevention and intervention programmes with female adolescents.

- Purpose: Although the experience of body image has been considered an important indicator of women's psychological quality of life (QoL), it has also been suggested that the impact of unwanted body-related experiences on QoL may be mediated by emotional regulation processes. The aim of the current study was therefore to explore for the first time the role of body image-related cognitive fusion on these associations.Methods: This study comprised 779 young females who completed self-report measures. A path analysis was conducted to explore whether BMI, body dissatisfaction and feelings of inferiority based on physical appearance would impact on psychological QoL through body image-related cognitive fusion.Results: The model explained 39 % of psychological health, and revealed an excellent fit. Results showed that BMI did not directly impact on psychological health. Furthermore, the effects of increased body dissatisfaction and feelings of inferiority based on physical appearance on psychological health were fully and partially mediated by body image-related cognitive fusion, respectively.Conclusions: These findings suggest that the presence of body image-related negative experiences does not necessarily lead to impairment in women's QoL, which is rather dependent upon one's ability to observe these unwanted experiences as transient and subjective. Therefore, intervention programmes aiming at increasing women's QoL should focus on targeting emotional regulation processes in order to develop the ability to pursue life goals and values, even in the presence of unwanted experiences concerning body image.

- Restrictive dieting is an increasing behavior presented by women in modern societies, independently of their weight. There are several known factors that motivate diet, namely a sense of dissatisfaction with one's body and unfavorable social comparisons based on physical appearance. However, dieting seems to have a paradoxical effect and has been considered a risk factor for weight gain and obesity in women and for maladaptive eating. Nevertheless, the study of the emotional regulation processes that explain the adoption of inflexible and rigid eating behaviors still remains little explored. In this line, the present study aims to explore why normal-weight women engage in highly rigid and inflexible diets. We hypothesize that body and weight dissatisfaction and unfavorable social comparisons based on physical appearance explain the adoption of inflexible eating rules, through the mechanisms of body image inflexibility. The current study comprised 508 normal-weight female college students. Path analyses were conducted to explore the study's hypotheses. Results revealed that the model explained 43 % of inflexible eating and revealed excellent fit indices. Furthermore, the unwillingness to experience unwanted events related to body image (body image inflexibility) mediated the impact of body dissatisfaction and unfavorable social comparisons on the adoption of inflexible eating rules. This study highlights the relevance of body image inflexibility to explain rigid eating attitudes, and it seems to be an important avenue for the development of interventions focusing on the promotion of adaptive attitudes towards body image and eating in young women.

- Literature suggested that the recall of early positive experiences have a major impact on the promotion of feelings of connectedness and social safeness, and seems to protect individuals against psychopathology. Recent research has also demonstrated that the absence of these positive rearing memories play a key role on disordered eating-related behaviours. The impact of early affiliative memories on disordered eating do not seem to be direct, and the mechanisms underlying this relationship are scarcely investigated. The present study aimed to clarify how memories of warmth and safeness explain the adoption of disordered eating attitudes, and tested the mediator role of social safeness, external shame and appearance-focused social comparison on aforementioned relationship, in a sample of 277 young women. The tested model explained 36% of eating psychopathology's variance and presented an excellent fit. Path analysis results indicated that the impact of rearing memories on eating psychopathology was fully mediated through the mechanisms of social safeness, external shame and appearance-focused social comparison. Specifically, these findings suggested that the extent to which positive rearing memories are associated with lower levels of disordered eating attitudes is influenced by the current feelings of social safeness and connectedness, which in turn are totally carried by decreased feelings of external shame and by lower endorsement on unfavourable comparison based on physical appearance with proximal targets (peers). These results seem to offer important insights for research and clinical work on body image and eating-related difficulties, suggesting the relevance of promoting warm and safe interactions with others.Level of evidenceLevel V, descriptive study.

- Recently, several studies have pointed the importance of thought suppression as a form of experiential avoidance in different psychopathological conditions. Thought suppression may be conceptualized as an attempt to decrease or eliminate unwanted internal experiences. However, it encloses a paradoxical nature, making those thoughts hyper accessible and placing an extra burden on individuals. This avoidance process has been associated with several psychopathological conditions. However, its role in eating psychopathology remains unclear. The present study aims to explore the moderation effect of thought suppression on the associations between body image-related unwanted internal experiences (unfavorable social comparison through physical appearance and body image dissatisfaction) and eating psychopathology severity in a sample of 211 female students. Correlational analyses showed that thought suppression is associated with psychological inflexibility and eating disorders' main risk factors and symptoms. Moreover, two independent analyses revealed that thought suppression moderates, as it amplifies, the impact of unfavorable social comparisons through physical appearance (model 1) and body image dissatisfaction (model 2) on disordered eating attitudes and behaviors. Hence, for the same level of these body-related internal experiences, young females who reveal higher levels of thought suppression present higher eating psychopathology. Taken together, these findings highlight the key role of thought suppression in eating psychopathology and present important clinical implications.
