RESUMO

BACKGROUND: The dynamics of global, state-dependent reconfigurations in brain connectivity are yet unclear. We aimed at assessing reconfigurations of the global signal correlation coefficient (GSCORR), a measure of the connectivity between each voxel timeseries and the global signal, from resting-state to a stop-signal task. The secondary aim was to assess the relationship between GSCORR and blood-oxygen-level-dependent (BOLD) activations or deactivation across three different trial-conditions (GO, STOP-correct, and STOP-incorrect). METHODS: As primary analysis we computed whole-brain, voxel-wise GSCORR during resting-state (GSCORR-rest) and stop-signal task (GSCORR-task) in 107 healthy subjects aged 21-50, deriving GSCORR-shift as GSCORR-task minus GSCORR-rest. GSCORR-tr and trGSCORR-shift were also computed on the task residual time series to quantify the impact of the task-related activity during the trials. To test the secondary aim, brain regions were firstly divided in one cluster showing significant task-related activation and one showing significant deactivation across the three trial conditions. Then, correlations between GSCORR-rest/task/shift and activation/deactivation in the two clusters were computed. As sensitivity analysis, GSCORR-shift was computed on the same sample after performing a global signal regression and GSCORR-rest/task/shift were correlated with the task performance. RESULTS: Sensory and temporo-parietal regions exhibited a negative GSCORR-shift. Conversely, associative regions (ie. left lingual gyrus, bilateral dorsal posterior cingulate gyrus, cerebellum areas, thalamus, posterolateral parietal cortex) displayed a positive GSCORR-shift (FDR-corrected p < 0.05). GSCORR-shift showed similar patterns to trGSCORR-shift (magnitude increased) and after global signal regression (magnitude decreased). Concerning BOLD changes, Brodmann area 6 and inferior parietal lobule showed activation, while posterior parietal lobule, cuneus, precuneus, middle frontal gyrus showed deactivation (FDR-corrected p < 0.05). No correlations were found between GSCORR-rest/task/shift and beta-coefficients in the activation cluster, although negative correlations were observed between GSCORR-task and GO/STOP-correct deactivation (Pearson rho=-0.299/-0.273; Bonferroni-p < 0.05). Weak associations between GSCORR and task performance were observed (uncorrected p < 0.05). CONCLUSION: GSCORR state-dependent reconfiguration indicates a reallocation of functional resources to associative areas during stop-signal task. GSCORR, activation and deactivation may represent distinct proxies of brain states with specific neurofunctional relevance.

RESUMO

BACKGROUND: Childhood traumatic experiences have been associated with hypersexuality and sexual dysfunctions. However, the mediators of the interactions between these variables should be clarified in men. AIM: This study aimed to investigate the interaction of early traumatic experiences, psychopathology, and sexuality with respect to erectile dysfunction (ED) and hypersexual behavior. The hypothesized model expected that traumatic experiences would be associated with hypersexual behavior and reduced sexual functioning through the mediation of body uneasiness and psychological distress. METHODS: The study was cross-sectional and observational. A total of 317 men were enrolled. Male patients with a primary complaint of ED and an indication for psychiatry referral represented the clinical sample (n = 116; mean ± SD age, 42.82 ± 16.89 years). Clinical classification was assessed with the Structured Interview on Erectile Dysfunction. The second sample (n = 201, 30.82 ± 11.94 years) was recruited from the general population. All participants were administered the following questionnaires: Brief Symptom Inventory, Childhood Trauma Questionnaire-Short Form, Hypersexual Behavior Inventory, Body Uneasiness Test-A, and 5-item International Index of Erectile Function. OUTCOMES: Psychopathology and sexual functioning were assessed by a dimensional approach, and a multivariate model was computed by structural equation model analysis. RESULTS: When compared with the sample from the general population, the clinical sample exhibited a higher prevalence of early traumatic experiences, as measured by scores on the Childhood Trauma Questionnaire-Short Form (45.08 ± 14.25 vs 39.03 ± 10.22, F = 17.63, P < .001), and a higher tendency to engage in hypersexual behaviors (34.63 ± 13.55 vs 30.79 ± 12.44, F = 6.97, P < .01). Structural equation model analysis showed excellent fit indices indicating that early traumatic experiences predicted hypersexual behaviors and ED through the exacerbating mediating effect of body uneasiness and psychopathology. CLINICAL IMPLICATIONS: Clinicians should not limit their attention to the behavioral level when assessing sexual dysfunction in men; rather, they should also consider the complex psychopathologic consequences of childhood trauma. Integrated treatments that address the potential presence of childhood trauma with its wider psychological correlates (eg, emotion dysregulation, body uneasiness) might improve treatment response. STRENGTHS AND LIMITATIONS: The study reports novel data on the relationship among childhood maltreatment, male sexuality, and psychopathologic mediators with a dimensional assessment. However, the assessment was cross-sectional, and causality was mainly derived from previous studies. CONCLUSION: The present study enriches the current literature, strengthening the hypothesis that childhood traumatic experiences significantly shape development and sexuality. Body uneasiness and psychopathology can both tax sexual functioning, as assessed by erectile functioning or hypersexuality.

RESUMO

BACKGROUND: A better characterization of educational processes during psychiatry training is needed, both to foster personal resilience and occupational proficiency. METHODS: An adequate coverage of medical residents at the national level was reached (41.86% of the total reference population, 29 out of 36 training centers-80.55%). Controls were recruited among residents in other medical specialties. All participants were assessed by questionnaires to evaluate early life experiences, attachment style, personality traits, coping strategies, emotional competencies. A Structural Equation Model (SEM) framework was employed to investigate the interplay between individual factors. RESULTS: A total sample of 936 people was recruited (87.9% response-rate; 645 residents in psychiatry, 291 other medical residents). Psychiatry trainees reported a higher prevalence of adverse childhood experiences (emotional abuse, emotional neglect, physical neglect), greater attachment insecurity (anxious or avoidant) in comparison to other medical trainees. Psychiatry residents also reported higher social support-seeking as a coping strategy, lower problem-orientation, and lower transcendence. Lower neuroticism, higher openness to experience, and higher emotional awareness were also observed in psychiatry trainees. Psychiatry training was associated with a redefinition of conflict management skills as a function of seniority. The SEM model provided support for an interplay between early traumatic experiences, mentalization skills (coping strategies, emotion regulation), interpersonal competencies and occupational distress. CONCLUSIONS: The findings of the present study supported a theoretical model based on mentalization theory for the interactions between personal and relational competencies in psychiatry training, thus providing potential target of remodulation and redefinition of this specific process of education.

RESUMO

PURPOSE: To assess the knowledge, clinical experience, and attitudes of Italian midwives toward perinatal depression (PND) and to explore how these factors impact the quality of care. METHODS: We conducted a cross-sectional online survey among 152 midwives employed in public hospitals across Italy. The questionnaire covered a range of topics, including demographic data, professional experience, knowledge of PND symptoms, risk factors, and clinical management, as well as communication skills and personal experiences with PND cases. RESULTS: A concerning 76.3% of midwives displayed inadequate knowledge of PND based on current scientific literature. Those with a more comprehensive understanding were notably more confident in their practice, expressing significantly fewer apprehensions about communicating with mothers (25.8% vs 74.2%) and lesser concerns about the mothers' future well-being (38.9% vs 62.95%). The survey results also emphasised the midwives' call for specialised guidelines and formal training in PND management and underscored the value of communication skills, continuity of care, and family engagement in supporting affected mothers. CONCLUSION: This inaugural study sheds light on the current state of knowledge and attitudes among Italian midwives regarding PND. It pinpoints crucial areas for educational enhancement and practice improvement, suggesting that elevated levels of midwife expertise in PND could significantly elevate the standard of care and expedite early diagnosis and treatment.

RESUMO

OBJECTIVE: This quasi-experimental study aimed to compare the outcome of patients with Anorexia Nervosa (AN) reporting moderate/severe childhood maltreatment (CM) treated exclusively with Enhanced Cognitive Behaviour Therapy (CBT-E) or with CBT-E plus Eye Movement Desensitisation and Reprocessing (EMDR). METHOD: A total of 75 patients with AN reporting moderate/severe CM were initially assessed regarding body mass index (BMI), general and eating disorder (ED)-specific psychopathology, and dissociative symptoms, and re-evaluated after 40 CBT-E sessions (T1). Then, 18 patients received EMDR, whereas the others were placed on a waiting list and continued CBT-E. T2 assessment was performed after 20-25 sessions of EMDR or CBT-E. A control group of 67 patients without CM was also enroled and treated with CBT-E. RESULTS: Contrary to patients without CM, neither of the traumatised groups improved in BMI, general and ED psychopathology, or dissociation at T1. However, at T2, both traumatised groups improved in BMI and ED-specific psychopathology, with the CBT + EMDR group demonstrating greater improvements. Moreover, only the CBT + EMDR group improved in general psychopathology and dissociative symptoms. The reduction of ED symptoms in traumatised patients was mediated by the amelioration of dissociation. DISCUSSION: The addition of EMDR to CBT-E may benefit patients with AN reporting moderate/severe CM.

RESUMO

BACKGROUND: Phenomenological research has enriched the scientific and clinical understanding of Eating Disorders (ED), describing the significant role played by disorders of embodiment in shaping the lived experience of patients with ED. According to the phenomenological perspective, disorders of embodiment in ED are associated with feelings of alienation from one's own body, determining an excessive concern for external appearance as a form of dysfunctional coping. The purpose of the present narrative review is to address the role of gender identity as a risk factor for EDs in the light of phenomenological approaches. METHODS: Narrative review. RESULTS: The current study discusses the interplay between perception, gender identity, and embodiment, all posited to influence eating psychopathology. Internalized concerns for body appearance are described as potentially associated with self-objectification. Furthermore, concerns on body appearance are discussed in relation to gendered social expectations. The current review also explores how societal norms and gender stereotypes can contribute to dysfunctional self-identification with external appearances, particularly through an excessive focus on the optical dimension. The socio-cultural perspective on gender identity was considered as a further explanation of the lived experience of individuals with ED. CONCLUSIONS: By acknowledging the interplay between these factors, clinicians and researchers can gain a deeper understanding of these disorders and develop more effective interventions for affected individuals. LEVEL OF EVIDENCE: Level V narrative review.

RESUMO

PURPOSE: Individuals with anorexia nervosa (AN) and bulimia nervosa (BN) frequently exhibit Non-Suicidal Self-Injury (NSSI), yet their co-occurrence is still unclear. To address this issue, the aim of this study was to elucidate the role of impairments in interoception in explaining the NSSI phenomenon in AN and BN, providing an explanatory model that considers distal (insecure attachment/IA and traumatic childhood experiences/TCEs) and proximal (dissociation and emotional dysregulation) risk factors for NSSI. METHOD: 130 patients with AN and BN were enrolled and administered self-report questionnaires to assess the intensity of NSSI behaviors, interoceptive deficits, IA, TCEs, emotional dysregulation and dissociative symptoms. RESULTS: Results from structural equation modeling revealed that impairments in interoception acted as crucial mediators between early negative relational experiences and factors that contribute to NSSI in AN and BN, particularly emotional dysregulation and dissociation. Precisely, both aspects of IA (anxiety and avoidance) and various forms of TCEs significantly exacerbated interoceptive deficits, which in turn are associated to the emergence of NSSI behaviors through the increase in levels of dissociation and emotional dysregulation. CONCLUSIONS: The proposed model provided a novel explanation of the occurrence of NSSIs in patients with AN and BN by accounting for the significance of interoception. LEVEL OF EVIDENCE: Level V-Cross-sectional observational study.

RESUMO

BACKGROUND: Given the relationship between interiorized stigma and body image, it could be hypothesized that high levels of internalized transphobia (IT) might predict higher levels of body uneasiness in subjects with gender dysphoria (GD) and worse improvement of body image after gender affirming hormone therapy (GAHT). AIM: We sought to evaluate the relationship between IT and body uneasiness in subjects with GD and the role of IT in moderating the improvement of body image after GAHT. METHODS: In total, 200 individuals with GD performed the baseline assessment; 99 were re-evaluated 12 months after starting GAHT. At baseline participants were evaluated through a face-to-face interview and filled self-administered questionnaires to evaluate GD (Utrecht Gender Dysphoria Scale [UGDS]), IT attitudes (Attitudes Toward Transgendered Individuals [ATTI] Scale), body uneasiness (Body Uneasiness Test, part A [BUT-A]), and general psychopathology (Symptom Checklist 90-Revised [SCL 90-R]). The same questionnaires, except ATTI, were readministered at follow-ups. OUTCOMES: Outcomes were based on measures of the associations between IT and baseline characteristics of the sample, the longitudinal trends of GD, body uneasiness, and general psychopathology; and IT as a moderator of the longitudinal trend of body uneasiness. RESULTS: At baseline, IT correlated with lower level of education, higher GD, and more severe body uneasiness. Longitudinal analyses showed significant improvements in GD, body uneasiness, and general psychopathology during GAHT. Moderation analysis confirmed that participants with more transphobic attitudes showed less improvement after GAHT with regard to body uneasiness (bTime*ATTI = -.002, P = .040). The Johnson-Neyman technique revealed that no significant improvement in body uneasiness was found for participants with ATTI scores lower than 71.14. CLINICAL IMPLICATIONS: The presence of IT should be investigated in subjects with GD who require gender affirming treatments to provide specific interventions aimed at targeting this dimension. STRENGTHS AND LIMITATIONS: Strengths of this study include the mixed cross-sectional and longitudinal design and the dimensional evaluation of the investigated constructs. Limitations include the small sample size and the limited follow-up. Furthermore, the effects of gender affirming surgery were not evaluated. CONCLUSION: The association of IT with both baseline body uneasinessand the longitudinal course of this dimension highlighted the clinical significance of body uneasiness and the importance of making continuous efforts to improve education and information to fight societal stigmas.

RESUMO

INTRODUCTION: Eating disorders (EDs) are considered serious mental illnesses, with one of the highest lethality among psychiatric disorders, even though the issue of mortality due to these conditions is still controversial. The present study was aimed at comparing the mortality rate in a cohort of ED patients representative of the geographic area with that of the age and gender-matched general population of central Italy. METHODS: Patients were enrolled between 1994 and 2018, among those attending the eating disorders treatment network of the Florence area (EDTN), which is a regional multidisciplinary treatment reference center for EDs covering the clinical population of the metropolitan Florence area (Italy). The life status of participants was determined through linkage with the Regional Mortality Registry. RESULTS: A total of 1277 individuals with EDs were included, including 368 with Anorexia Nervosa (AN), 312 with Bulimia Nervosa (BN), and 597 individuals with Binge Eating Disorder (BED). Twenty-two patients (1.72%) died, during a median follow-up of 7.4 years. The mortality rates among ED patients did not significantly differ from that of the general population of the same age and sex with a Standardized Mortality Ratio (SMR) of 1.19, 95% CI 0.79-1.81. Only among BN patients, the mortality was significantly increased after 10 years from clinical evaluation (SMR 11.24, 95% CI 3.62-34.84). CONCLUSION: The low mortality in EDs, compared to published studies, might be due to the EDTN treatment strategy, based on a large network which makes an integrated multidisciplinary team available for almost all the patients with EDs of the geographical area.

RESUMO

PURPOSE: Adverse effects of selective serotonin reuptake inhibitors (SSRIs) on sexual function have been an important area of research for many years. However, the duration of SSRI-associated sexual adverse effects, and their possible persistence after treatment discontinuation, is still uncertain. The aims of the current systematic review were first to identify existing evidence of sexual dysfunction following SSRI discontinuation, and to provide an account of reported symptoms and proposed treatment options; and second, to establish whether current literature allows accurate estimates of the prevalence of such sexual dysfunction. METHODS: A systematic review was conducted on PubMed, Embase, and Google Scholar; papers with clinical data regarding patients with persistent sexual dysfunction after SSRI treatment suspension were included. RESULTS: Overall, two retrospective interventional studies, six observational studies and 11 case reports were judged eligible for inclusion. It was not possible to determine reliable estimates of prevalence. Similarly, a cause-effect relationship between SSRI exposure and persistent sexual impairment could not be ascertained. Nonetheless, the potential for continued sexual disturbances despite discontinuation could not be entirely ruled out. CONCLUSIONS: There is a need to investigate a possible dose-response relationship between SSRI exposure and persistent sexual adverse effects. Treatment options for persistent dysfunctions remain limited, but novel therapeutic approaches may be required in order to address an otherwise neglected need for sexual well-being.

RESUMO

BACKGROUND: Mental disorders are a major public health problem. However, over the last few years, there have been few studies aimed at evaluating their diffusion. Therefore, this study aimed at evaluating: the prevalence of the most frequent psychiatric disorders in the general population residing in Tuscany using a clinical scale administered by trainee in psychiatry. METHODS: The study was carried out on a representative sample of the general population aged > 18 years, randomly extracted from the register of patients in the Tuscany region, adopting a proportional sampling method stratified by gender, age group and Local Health Units (LHU). Each person was contacted by letter followed by a phone call from an operator who makes an appointment with the trainee in psychiatry. The diagnostic interview conducted was the Mini-International Neuropsychiatric Interview (MINI). Point and lifetime prevalence by gender and age group were calculated. Differences and associations were considered statistically significant if their p-values were less than 0.05. RESULTS: Of the 408 people involved, 390 people were enrolled (of which 52.6% female). The 28.5% of the sample had been affected by a psychiatric disorder during their lifetime. In their lifetime, the most represented psychiatric disorders were major depressive episode (20.4%), major depressive disorder (17.0%) and panic disorder (10.3%), more frequent in the female than the male group. Current conditions were predominantly major depressive episode (3.1%) and agoraphobia (2.8%). A 5.9% rate of current suicidal ideation was also found. CONCLUSIONS: In the general population, 28.5% of people reported a psychiatric disorder during their lifetime. This prevalence is considerably higher than that reported in a previous study carried out in central Italy.

RESUMO

BACKGROUND: Menstrual cycle has a significant impact on women's health from different perspectives, both physically and psychologically. The assessment of menstrual-related distress is of pivotal clinical interest, especially in women with chronic exposure to abnormal bleeding or pain. The Menstrual Distress Questionnaire (MEDI-Q) is a new tool originally developed in Italian that comprehensively evaluates menstrual-related distress. OBJECTIVE: To validate the English version of the MEDI-Q in an English-speaking population. METHODS: The study consisted of two phases: an initial translation phase of the original Italian version of the MEDI-Q, and a data collection phase to validate the new English version among 288 native English-speaking women. RESULTS: The English version of MEDI-Q showed excellent psychometric properties, with high internal consistency (Cronbach's alpha = 0.84) and test-retest reliability (intraclass correlation coefficient = 0.95). Construct validity was supported by significant correlations between MEDI-Q scores and scores on measures of psychological distress and premenstrual symptoms. CONCLUSIONS: The English version of the MEDI-Q is a valid and reliable instrument for the assessment of menstrual distress and its impact on psychological well-being. This tool can be utilized in research and clinical settings to comprehensively investigate the impact of menstruation on various populations, identify and monitor menstruation-related disorders promptly and effectively, and to evaluate the effectiveness of targeted treatments for menstrual distress.

RESUMO

An emerging body of research has evidenced the negative influence of using and being exposed to social networking sites (SNSs) on body image. Furthermore, it has been postulated that SNS use might be related with onset and persistence of eating disorders (EDs) psychopathology. The aim of the present study is to evaluate the complex interplay between problematic Instagram use (PIU) (conceptualized as a potential behavioral addiction comprising withdrawal, conflict, tolerance, salience, mood modification and relapse) and ED psychopathology, by means of an explanatory structural equation model. We hypothesized that PIU would be associated with ED symptoms through the mediating role of appearance comparison, individual psychological investment in physical appearance, and body uneasiness. A sample of 386 young female participants (Mage = 26.04 ± 6.73) was recruited, of which 152 had received a diagnosis of ED. ED patients used Instagram more than the control group and showed higher levels of PIU. Results from structural equation modeling (fit indices: χ2 = 44.54, df = 19, p < 0.001; RMSEA = 0.059; CFI = 0.98; SRMR = 0.02) showed that PIU predicted appearance comparison and psychological investment in physical appearance, which in turn predicted body uneasiness. In turn, body uneasiness predicted ED psychopathology and interpersonal difficulties. Our model provides a useful account of how eating disorder symptoms could be triggered and maintained by an addictive use of Instagram.

RESUMO

Homotopic connectivity during resting state has been proposed as a risk marker for neurologic and psychiatric conditions, but a precise characterization of its trajectory through development is currently lacking. Voxel-Mirrored Homotopic Connectivity (VMHC) was evaluated in a sample of 85 neurotypical individuals aged 7-18 years. VMHC associations with age, handedness, sex, and motion were explored at the voxel-wise level. VMHC correlates were also explored within 14 functional networks. Primary and secondary outcomes were repeated in a sample of 107 adults aged 21-50 years. In adults, VMHC was negatively correlated with age only in the posterior insula (false discovery rate p < .05, >30-voxel clusters), while a distributed effect among the medial axis was observed in minors. Four out of 14 considered networks showed significant negative correlations between VMHC and age in minors (basal ganglia r = -.280, p = .010; anterior salience r = -.245, p = .024; language r = -.222, p = .041; primary visual r = -.257, p = .017), but not adults. In minors, a positive effect of motion on VMHC was observed only in the putamen. Sex did not significantly influence age effects on VMHC. The current study showed a specific decrease in VMHC for minors as a function of age, but not adults, supporting the notion that interhemispheric interactions can shape late neurodevelopment.

RESUMO

Adiponectin (ADPN), a hormone produced by adipose tissue, facilitates gastric relaxation and can be a satiety signal in the network connecting peripheral organs and the central nervous system for feeding behavior control. Here, we performed preclinical research by morpho-functional analyses on murine gastric fundus smooth muscle to add insights into the molecular mechanisms underpinning ADPN action. Moreover, we conducted a clinical study to evaluate the potential use of ADPN as a biomarker for eating disorders (ED) based on the demonstrated gastric alterations and hormone level fluctuations that are often associated with ED. The clinical study recruited patients with ED and healthy controls who underwent blood draws for ADPN dosage and psychopathology evaluation tests. The findings of this basic research support the ADPN relaxant action, as indicated by the smooth muscle cell membrane pro-relaxant effects, with mild modifications of contractile apparatus and slight inhibitory effects on gap junctions. All of these actions engaged the ADPN/nitric oxide/guanylate cyclase pathway. The clinical data failed to unravel a correlation between ADPN levels and the considered ED, thus negating the potential use of ADPN as a valid biomarker for ED management for the moment. Nevertheless, this adipokine can modulate physiological eating behavior, and its effects deserve further investigation.

RESUMO

The overarching theme of causality in behavioral genetics is discussed on epistemological grounds. Evidence is offered in favor of a continuum spectrum in causality, in contrast to discrimination between causal factors and associations. The risk of invalidating exploratory studies in behavior genetics is discussed, especially for the potential impact on those fields of medicine interested in complex behaviors.

RESUMO

INTRODUCTION: The Aberrant Salience Inventory (ASI) is a useful tool to measure salience abnormalities among the general population. There is strong clinical and scientific evidence that salience alteration is linked to psychosis. To the present day, no meta-analysis evaluating ASI's psychometric properties and screening potential has been published. MATERIALS AND METHODS: PubMed, Google Scholar, Scopus, and Embase were searched using terms including "psychosis," "schizophrenia," and "Aberrant Salience Inventory." Observational and experimental studies employing ASI on populations of non-psychotic controls and patients with psychosis were included. ASI scores and other demographic measures (age, gender, ethnicity) were extracted as outcomes. Individual patients' data (IPD) were collected. Exploratory factor analysis (EFA) was performed on the IPD. RESULTS: Eight articles were finally included in the meta-analysis. ASI scores differ significantly between psychotic and non-psychotic populations; a novel three-factor model is proposed regarding subscales structure. Theoretical positive predictive values (PPVs) and negative predictive values (NPVs) were calculated and presented together with different cutoff points depending on preselected specific populations of interest. DISCUSSION: PPV and NPV values reached levels adequate for ASI to be considered a viable screening tool for psychosis. The factor analysis highlights the presence of a novel subscale that was named "Unveiling experiences." Implications regarding the meaning of the new factor structure are discussed, as well as ASI's potential as a screening tool.

RESUMO

PURPOSE: Disordered eating and body image concerns are increasingly common among adolescents, possibly representing the underpinning of eating disorders (EDs). This cross-sectional observational study aimed at investigating the relationship between various patterns of sports involvement or inactivity, and the abovementioned psychopathological dimensions. METHODS: All adolescents attending their 3rd-5th Italian grade in a single high school reported their sociodemographic and anthropometric data, their weekly sports involvement, and filled the Eating Disorders Examination Questionnaire 6.0 (EDE-Q), the Body Uneasiness Test, and the Muscle Dysmorphia Disorder Inventory (for boys). Comparisons were performed considering sex, weekly hours of activity, and different sports type (none, individual, or team sports). RESULTS: Of 744 enrolled students, 522 (70.2%) completed the survey. Girls showed higher underweight rates, preference for inactivity or individual sports, and higher psychometric scores compared to boys. Among girls, no differences were found based on time spent exercising or sports type. Inactive boys displayed worse weight- and shape-based psychopathology, higher body uneasiness, and higher appearance intolerance compared to those who devoted more time to exercise. Among boys, individual and team sports were associated with lower EDE-Q scores compared to inactivity, whereas body uneasiness and appearance intolerance were lower only in team sports. CONCLUSIONS: The study confirms the presence of remarkable sex differences in eating and body concerns of adolescents. Among boys, sports involvement is tied to lower ED psychopathology, and preference for team sports may be associated with reduced concerns. Wider longitudinal studies on will clarify the direction and specificity of these findings. LEVEL OF EVIDENCE: Level V-Cross-sectional observational study.

RESUMO

PURPOSE: Pregorexia is a phenomenon posited to occur in the peripartum, characterized by an attempt to counter pregnancy's physiological changes in body shape through reduced calorie intake or increased physical activity. METHODS: In this pre-registered systematic review and meta-analysis, body image dissatisfaction and eating psychopathology in the peripartum according to gestational age were formally assessed. PubMed was searched up to May 2023. Selection criteria were represented by studies on body image concerns or eating psychopathology in the peripartum (up to 1 year after delivery). The population needed to include women from the general population or among patients with a history of (or current) eating disorder. For the meta-analysis, 17 studies were included: 10 for body image dissatisfaction (2625 individuals overall), 7 for eating behaviors (2551 individuals overall). The interplay between body image and the following themes was examined in depth: the adoption of breastfeeding, peripartum depression, sociocultural influences on body image, sexual disturbances, experiencing or reporting an altered food intake. RESULTS: Progressive dissatisfaction with body image during pregnancy by gestational age was observed, stably elevated for at least 12 months postpartum. Eating psychopathology was observed as elevated only at 12 months in the postpartum, but not during pregnancy. DISCUSSION: The current work offers normative values of body image satisfaction and eating psychopathology in the peripartum by gestational age. The relevance of current results was discussed, in order to inform both current clinical practice and future public policies. LEVEL OF EVIDENCE: Level I-Evidence obtained from: systematic reviews and meta-analyses.

RESUMO

PURPOSE: Health Literacy (HL) consists in all the skills and knowledges used by people to understand and seek health-related information. Inadequate levels of HL substantially affect many different aspects of health. The primary aim of the present study was to assess levels of HL in female patients with anorexia nervosa (AN) and bulimia nervosa (BN), compared with matched control subjects. METHODS: A consecutive series of 64 female patients with AN and BN (mean age 23.1 ± 7.0) was enrolled, matched with 64 female control subjects (mean age 23.7 ± 7.1). Both groups completed the Health Literacy Survey Questionnaire (HLS-EU-Q16) and the Newest Vital Sign (NVS), which evaluate subjective and objective HL level respectively. RESULTS: Patients with AN and BN showed lower levels of subjective HL (10.0 ± 3.5 vs. 11.3 ± 3.0) and higher levels of objective HL (5.0 ± 1.3 vs. 3.6 ± 1.6) when compared with controls. No difference between AN and BN was found. No correlation between HLS-EU-Q16 Total Score and duration of illness was found. A negative correlation was found between EDE-Q Eating Concerns and subjective HL levels. HLS-EU-Q16 Total Score was predicted by educational level in control subjects only, while NVS Total Score was not predicted by educational level in control subjects nor in patients. CONCLUSION: Patients with AN and BN had lower levels of subjective HL. NVS scores could overestimate objective HL in female patients with AN and BN. The promotion of HL in areas differing from those that concern nutritional characteristics of food, could be a therapeutic target for these patients. LEVEL OF EVIDENCE: III: Evidence obtained from well-designed cohort or case-control analytic studies.
