A cultural models approach to understanding body fatness perceptions and disordered eating in young South Korean men.

The eating disorders field has been limited by a predominant focus on White, Western women, and there is growing recognition of the need to understand cross-cultural variation in key constructs (i.e., ideal body types). A transdisciplinary, cultural models approach systematizes the incorporation of an "emic" perspective (a culture's own understandings of phenomena) into assessments of relationships between body shapes and eating disorders. Eighty-one young South Korean men aged 19-34 years living in Seoul participated in this research. A cultural model of body fatness was identified using cultural consensus analysis during 18 months of ethnographic, mixed-methods fieldwork. Participants also completed questionnaires assessing age, height, weight, sexual identity, university prestige, body dissatisfaction, eating disorder symptoms, and cultural consonance with the Korean cultural model of the ideal male body. Variation in these factors was analyzed using a series of chi-squares and analyses of variance with the culturally defined categories of body fatness as the independent variables. Cultural consensus analysis found that young South Korean men are consistent in identifying categories of "too thin," "balanced," and "too fat." The "balanced" category contained the lowest proportion of high-prestige university attendees and the highest average cultural consonance. The "too fat" category was characterized by the highest levels of body dissatisfaction and dieting, as well as proportion of probable eating disorders. A cultural models approach identified culturally important factors and patterns in disordered eating among young South Korean men and may be effective for understanding eating disorders in other populations not typically studied. This study applies a systematic, "emic" perspective to young South Korean men's body ideals. Young Korean men share a cultural model of body fatness, and this model frames how they experience risk for eating disorders. This study demonstrates a method for incorporating culture into research on eating disorder risk.

Are two beneficial mutations (p.Q249R and 90-bp Indel) within the ovine BMPRIB gene associated with growth traits?

The problem of achieving economic efficiency in sheep breeding can be largely solved by increasing sheep productivity. Recently, the BMPRIB gene has been revealed by GWAS as a potential candidate gene for sheep body morphometric traits. Therefore, the present study aimed to investigate whether genetic polymorphisms (p.Q249R SNP and 90-bp deletion) in the BMPRIB gene are associated with sheep growth traits. PCR-based genotyping was performed on 1,875 sheep, including 1,191 Guiqian semi-fine wool (GQSFW), 560 Luxi Blackhead (LXBH), 55 Lanzhou fat-tailed (LZFT), and 69 Weining (WN) sheep. Genotype-phenotype association was assessed using the independent samples t-test and ANOVA. The significance level was set at αoriginal < 0.05. The threshold p-value for significance was adjusted after correction for multiple comparisons using the Bonferroni correction. After the Bonferroni correction, it was found that individuals with FecB+/FecB+ genotypes of the p.Q249R had significantly better growth traits in LXBH ewe lambs, including the body length, chest width, paunch girth, cannon circumference, and hip width (P<0.0005). Meanwhile, associations were observed between 90-bp deletion polymorphism and several growth traits (body length, body height, chest depth, and canon circumference) in GQSFW ewe adults after the Bonferroni correction (P < 0.0002), and individuals with the "DD" genotypes had greater growth traits. Our findings align with the experimental observations from GWAS, which identified the BMPRIB gene as a potential candidate gene for body measurement traits. These findings not only confirm the previous study's results but also expand on them. Therefore, further investigations regarding the impact of BMPRIB polymorphisms on growth traits are necessary in other sheep breeds.

Coastal Groundwater Bodies Modelling Using Geophysical Surveys: The Reconstruction of the Geometry of Alluvial Plains in the North-Eastern Sicily (Italy)

The integration of various geophysical methodologies is considered a fundamental tool for accurately reconstructing the extent and shape of a groundwater body and for estimating the physical parameters that characterize it. This is often essential for the management of water resources in areas affected by geological and environmental hazards. This work aims to reconstruct the pattern and extent of two groundwater bodies, located in the coastal sectors of the North-Eastern Sicily, through the integrated analysis and interpretation of several geoelectrical, seismic and geological data. These are the Sant’Agata-Capo D’Orlando (SCGWB) and the Barcelona-Milazzo (BMGWB) Groundwater Bodies, located at the two ends of the northern sector of the Peloritani geological complex. These two studied coastal plains represent densely populated and industrialized areas, in which the quantity and quality of the groundwater bodies are under constant threat. At first, the resistivity models of the two groundwater bodies were realized through the inversion of a dataset of Vertical Electrical Soundings (VES), constrained by stratigraphic well logs data and other geophysical data. The 3D resistivity models obtained by spatially interpolating 1D inverse VES models have allowed for an initial recognition of the distribution of groundwater, as well as a rough geological framework of the subsoil. Subsequently, these models were implemented by integrating results from active and passive seismic data to determine the seismic P and S wave velocities of the main lithotypes. Simultaneous acquisition and interpretation of seismic and electrical tomographies along identical profiles allowed to determine the specific values of seismic velocity, electrical resistivity and chargeability of the alluvial sediments, and to use these values to constrain the HVSR inversion. All this allowed us to recognize the areal extension and thickness of the various lithotypes in the two investigated areas and, finally, to define the depth and the morphology of the base of the groundwater bodies and the thickness of the filling deposits.

Three-dimensional vertebral shape changes confirm growth modulation after anterior vertebral body tethering for idiopathic scoliosis.

To evaluate three-dimensional (3D) vertebra and disk shape changes over 2years following anterior vertebral body tether (AVBT) placement in patients with idiopathic scoliosis (IS). Patients with right thoracic IS treated with AVBT were retrospectively evaluated. 3D reconstructions were created from biplanar radiographs. Vertebral body and disk height (anterior, posterior, left and right) and shape (wedging angle) were recorded over the three apical segments in the local vertebral reference planes. Changes in height and wedging were measured through 2years postoperatively. Change in patient height was correlated with changes in the spine dimensions. Forty-nine patients (Risser 0-3, Sanders 2-4) were included. The mean age was 12.2 ± 1.4years (range 8-14). The mean coronal curve was 51 ± 10° preoperatively, 31 ± 9° at first postoperative time point and 27 ± 11° at 2-year follow-up (p < 0.001). The mean patient height increased 8cm by 2years (p < 0.001). The left side of the spine (vertebra + disc) grew in height by 2.2mm/level versus 0.7mm/level on the right side (p < 0.001). This differential growth was composed of 0.5mm/vertebral level and 1.0mm/disk level. Evaluation of the change in disk heights showed significantly decreased height anteriorly (- 0.4mm), posteriorly (- 0.3mm) and on the right (- 0.5mm) from FE to 2years. Coronal wedging reduced 2.3°/level with 1.1°/vertebral level change and 1.2°/disk level. There was no differential growth in the sagittal plane (anterior/posterior height). Patient height change moderately correlated with 3D measures of vertebra + disk shape changes. Three-dimensional analysis confirms AVBT in skeletally immature patients results in asymmetric growth of the apical spine segments. The left (untethered) side length increased more than 3 × than the right (tethered) side length with differential effects observed within the vertebral bodies and disks, each correlating with overall patient height change.

Understanding Senior Adults' Needs, Preferences, and Experiences of Commercial Exergames for Health: Usability Study.

Many senior adults are at risk of mental and physical disorders due to a lack of sufficient exercise. Therefore, adherent exercise should be urgently promoted to improve senior adults' muscle strength, preventing falls and conditions caused by physical and cognitive decline. However, off-the-shelf exercise games, so-called exergames, are mainly targeted at the younger generation or children, while senior adults are neglected, when this age group strongly needs exercise. Exergames could serve as a health intervention for promoting exercise. This study aimed to investigate senior adults' experience, perceptions, and acceptance of game technology to promote exercise in order to suggest game design guidelines. In this usability study, participants engaged in playing Nintendo Switch and Xbox Kinect games, after which semistructured interviews were conducted. Before the gameplay, the participants provided their background information, exercise habits, and use of technology products. Next, all participants completed a workshop including 3 activities (brief instructions on how to play the games: 20 minutes; playing the selected exergames: 80 minutes; semistructured interviews: 20 minutes) for 2 hours a day for 3 days each. The participants played the latest Nintendo Switch games (eg, Just Dance, Boxing, Ring Fit Adventure) and Xbox Kinect games (eg, Kinect Adventures!, Mini Games). Just Dance, Zumba, and Boxing were played in activity 1; Ring Fit Adventure and Mini Games in activity 2; and Kinect Adventures! in activity 3. Reflexive thematic analysis was applied to identify the relative themes generated from the interviews. In total, 22 participants (mean age 70.4, SD 6.1 years) were enrolled in the workshop in May 2021. The results of the generated themes included incomprehension of game instructions, psychological perception of game technology, and game art preferences. The subthemes generated from game art preferences included favorite game genres, characters, and scenes. There is a significant need for customized game tutorials considering senior adults' cognitive and physical aging. Furthermore, the adventure game genre is preferable to other games. Humanlike game characters are preferable, especially those with a fit and healthy body shape. Nature scenes are more enjoyable than indoor stages or rooms. Furthermore, the game intensity design and playing time should be carefully planned to meet the World Health Organization's criteria for physical activity in older adults. Intelligent recommendation systems might be helpful to support older adults with various health conditions. The guidelines suggested in this study might be beneficial for game design, exercise training, and game technology adoption of exergames for older adults to improve health.

A Review: Exploring Nutrition Approaches to Improve Mental Health Among Athletes: Focus on Depression and Disordered Eating

Elite sports environments can increase psychiatric conditions like stress and depression due to social pressure for specific body shapes, encouraging disordered eating behaviors, especially in endurance, aesthetic, and weight-dependent sports. This review aims to investigate eating habits among athletes suffering from poor mental health and identify dietary strategies or nutritional advice to mitigate these conditions in physically active individuals. The review focused on studies conducted after 2010 involving adults in any level of regular physical activity, showcasing psychiatric symptoms related to a disordered relationship with food, including depression and various eating disorders. The search on the literature databases was conducted on 20th October 2023 through multiple electronic databases (PubMed, SCOPUS, and Google Scholar) to capture as many relevant citations as possible. Exclusions were made for studies on children or psychiatric patients. The research was sourced from significant databases, emphasizing the correlation between dietary habits and mental health in athletes. Findings reveal that athletes, particularly in ultra-endurance and weight-dependent sports, are susceptible to psychiatric disorders such as depression, anxiety, and exercise addiction. Competitive bodybuilders also showed higher levels of depression and orthorexia nervosa symptoms. Tailored nutrition therapy, guided by healthcare professionals and adjusted to each athlete's specific needs and preferences, is crucial for addressing psychiatric symptoms and eating disorders in athletes. A holistic approach to recovery and well-being can significantly enhance both performance and overall quality of life, underscoring the importance of high-quality, balanced diets in supporting mental health and athletes' achievement.

Patterns of morphological diversification are influenced by dietary evolution in a highly species-rich lizard radiation

The diversification of lineages is facilitated or constrained by the simultaneous evolution of multiple components of the phenotype that interact with each other during the course of speciation. When evolutionary radiations are adaptive, lineages proliferate via the emergence of multiple phenotypic optima that underlie diversification of species across multiple ecological niches. When radiations are non-adaptive, lineage proliferation unfolds constrained by similar (or nearly identical) correlations among traits that keep phenotypic and ecological diversity across newly emerging species within a single optimum. Nature offers very few opportunities where both types of diversification occur between closely related and highly diverse lineages. The Liolaemidae family of South American lizards offers unique such opportunities given two speciose lineages that have rapidly proliferated via adaptive (Liolaemus) and non-adaptive (Phymaturus) radiations. We analyze body shape in lizards in association with type of diet (herbivory, omnivory or carnivory). In these lizards, diet types have been suggested to be linked to body size. Our results confirm this hypothesis, with three body size optima tightly linked to all three diet types when radiation is both adaptive and non-adaptive. Diet reconstruction along their evolutionary history showed that the common ancestor of Liolaemidae was likely omnivorous, which is matched by ancestral reconstruction of body size. Phylogenetic PCA revealed that herbivorous species generally have more differentiated body shape than insectivores and omnivores. Herbivorous species have evolved larger heads, shorter hindlimbs and a small difference between forelimb and hindlimb length. In contrast, omnivores and insectivores have smaller heads and longer hindlimbs. Collectively, trophic niche plays an important role in defining body shape and size across species within lineages, and the patterns of trait–ecology correlations remain consistent when lineages have diversified via adaptive and non-adaptive radiation.

Phenotypes of predator individuals underpin contrasting ecosystem effects

Abstract Intraspecific variability has implications for our understanding of ecosystem functioning. Yet, beyond ontogenetic variation in body size, we know little about how phenotypic differences between individuals modulate ecosystem functioning. We addressed this question empirically within a forested stream, by studying the ecosystem effects triggered by conspecific predatory dragonfly larvae that varied in sex, body shape, behaviour and growth rate. With the help of stream enclosures, we were able to evaluate how different predator phenotypes drive cascading effects on litter‐dwelling prey, fungal biomass and leaf litter decomposition, in uncontrolled natural conditions. Some individual predators increased leaf litter standing stocks and fungal biomass compared to controls (without dragonfly larvae added), but others had the opposite effect. These contrasting effects were repeatable between the two runs of our experiment. Phenotypic effects were related to the sex and the position of individuals along a life history—behavioural continuum, and were possibly mediated by differential top‐down control of prey, or by inter‐individual variability in non‐consumptive effects. Several phenotypic dimensions are likely to mediate individual variability in predator effects on ecosystem processes, even in a complex and stochastic natural context such as a forested stream. We invite further investigations that seek to understand the mechanisms (e.g., non‐consumptive effects) driving individual variability in predator effects on ecosystem processes.

Impact of body image and perceived stigmatization on the psychological wellbeing of obese women in Kumasi metropolis, Ghana.

Obesity is found to have a significant impact on body image perception and overall well-being. This study examines the impact of body image and perceived stigmatization on the psychological wellbeing of obese women in Kumasi metropolis, Ghana. A sample of 231 obese women was selected from health shops and some fitness centers using snowballing technique (purposive, snowballing technique and convenience). The study employed the descriptive survey design and made use of both descriptive and inferential data analysis approaches. The body shape questionnaire BSQ-34, the inventory of the Stigmatization Situation (SSI) and finally, the psychological well-being tools were used. Also, frequency distributions mean, and standard deviation, Pearson correlation coefficient and simple linear regression analysis were employed using SPSS version 23. Our findings indicated that obese women in the Kumasi metropolis were significantly satisfied with their body image. This is a true reflection of their higher self-esteem and standard of living. The body image and perceived stigmatization on the psychological wellbeing of the obese do have some counselling implications. Counselors, nutritionists, and clinical psychologists address specific schemes such as binge eating, dieting, and exercising to build the self-esteem of obese women.

Investigating the interplay of smoking, cardiovascular risk factors, and overall cardiovascular disease risk: NHANES analysis 2011–2018

BackgroundThis study explores the intricate relationship between smoking, cardiovascular disease (CVD) risk factors and their combined impact on overall CVD risk, utilizing data from NHANES 2011–2018.MethodsParticipants were categorized based on the presence of CVD, and we compared their demographic, social, and clinical characteristics. We utilized logistic regression models, receiver operating characteristics (ROC) analysis, and the chi-squared test to examine the associations between variables and CVD risk.ResultsSignificant differences in characteristics were observed between those with and without CVD. Serum cotinine levels exhibited a dose-dependent association with CVD risk. The highest quartile of cotinine levels corresponded to a 2.33-fold increase in risk. Smoking, especially in conjunction with lower HDL-c, significantly increases CVD risk. Combinations of smoking with hypertension, central obesity, diabetes, and elevated triglycerides also contributed to increased CVD risk. Waist-to-Height Ratio, Visceral Adiposity Index, A Body Shape Index, Conicity Index, Triglyceride-Glucose Index, Neutrophil, Mean platelet volume and Neutrophil to Lymphocyte ratio demonstrated significant associations with CVD risk, with varying levels of significance post-adjustment. When assessing the combined effect of smoking with multiple risk factors, a combination of smoking, central obesity, higher triglycerides, lower HDL-c, and hypertension presented the highest CVD risk, with an adjusted odds ratio of 14.18.ConclusionSmoking, when combined with central obesity, higher triglycerides, lower HDL-c, and hypertension, presented the highest CVD risk, with an adjusted odds ratio of 14.18.

Body contouring effects of at-home beauty device equipped with suction, radiofrequency, and electrical muscle stimulation functions.

With the rise in interest and demand for body contouring, beauty devices have continuously developed. Suction can aid in increasing the rate of fat breakdown by inducing a massage-like effect, thereby increasing blood flow. Moreover, radiofrequency (RF) can boost fibroblast activity and help reduce cellulite. In addition, electrical muscle stimulation (EMS) can use electrical stimulation to induce muscle contraction, leading to an athletic, and skin elasticity-increasing effect. This study aimed to assess the effects of body contouring, such as cellulite and swelling, in healthy Korean women to objectively prove the efficacy of an at-home beauty device equipped with suction, RF, and EMS functions. For 8 weeks, 21 participants used the at-home beauty device 3 days a week on their abdomen, thighs, and left calf. Validity assessments and subjective surveys were conducted at 4 and 8 weeks, including the first visit. The results of the validity assessments revealed that cellulite, swelling, elasticity, femoral skin texture, and dermal density were significantly (p < 0.05) improved in the experimental group compared with those at the baseline. The results of this study demonstrate that the combination of suction, RF, and EMS function is effective for body skin, fat, and body shape management. For better body-contouring effects, combining the beauty device with regular exercise and healthy eating habits is recommended.

Social Media and Body Image from the Perspective of Secondary School Youth

The study aimed to map the prevalence of social media disorder in secondary school youth. We used an abbreviated version of the Social Media Disorder Scale (SMD) and the Body Shape Questionnaire (BSQ-16B). The reliability of the questionnaires used in the research, indicates that they have sufficient internal consistency. A total of 637 re-respondents participated in the study. Their ages ranged from 15 to 19 years (AM=16.63). The results of the study showed social media impairment in 11.1% of the respondents, confirming a statistically significant difference in terms of the gender of the adolescents in favour of girls, and in terms of the degree of concern about their appearance, in favour of those who are more concerned about their appearance. Furthermore, a statistically significant difference in the degree of concern about their appearance in terms of gender, was confirmed in favour of girls.

Numerical analysis of turbulent nitrogen-diluted hydrogen flames stabilised by star-shaped bluff bodies

In this paper, we investigate the flow and flame dynamics within a combustion chamber supplied with nitrogen-diluted hydrogen fuel and air as oxidiser. The chamber is equipped with a bluff body that serves as a flame stabiliser. We focus primarily on the influence of the bluff body shape on the formation of large and small-scale vortical structures generated at the bluff body edge. We analyse how the geometry of the bluff body alters these structures and examine the impact of resulting modifications on flame characteristics, including key features such as flame length and radial extent, temperature and species field, and completeness of the combustion process. We consider four bluff body geometries, namely a typical cylindrical shape, a star-shaped wall, and a small triangular sharp and smooth wavy structure. The research employs the Large Eddy Simulation (LES) method, providing deep insight into the complex physics of unsteady flow. In the cylindrical bluff body configuration, the key mechanism driving the fuel-oxidiser mixing process is the periodic occurrence of large toroidal vortices shed at an exit of the oxidiser duct and on the bluff body edge. They exert the flow towards and away from a recirculation zone formed above the bluff body. When its geometry is irregular, the appearance of the large vortices is suppressed, however, the wall irregularities induce small-scale flow phenomena that enhance mixing in the shear layer formed between the recirculation zone and the oxidiser stream. The mixing efficiency is largely dependent on the shape of the bluff body wall, and it turns out that seemingly small changes (sharp vs. smooth small triangular parts), which in non-reactive regimes have only a minor effect on the flow dynamics, significantly change the flame length and fuel consumption rate. Compared to the cylindrical bluff body configuration, the small triangular parts cause an axial shift of the maximum temperature downstream and slow down fuel consumption. Contrary, large triangular elements in the star-shape bluff body clearly influence the flow both in non-reactive and reactive regimes. They cause the formation of local oxidiser streams directed towards the fuel-rich mixture. Consequently, the injected fuel burns at a rate similar to that observed in the case of the cylindrical bluff body, but the combustion process occurs at an average temperature approximately 200 K lower and its fluctuations are reduced. These factors may influence the thermal reduction of NOx. On the other hand, a negative aspect is the highest level of hydrogen in the closest vicinity of the bluff body, which in practical applications may accelerate the embrittlement of its surface.

Long-term growth, feed efficiency, enteric methane emission, and blood metabolite responses to in utero hyperthermia in Holstein heifers

Dairy producers are experiencing production and animal welfare pressures from the increasing frequency and severity of heat stress events due to global climate change. Offspring performance during the pre-weaning and lactating periods is compromised when exposed to heat stress during late gestation (in utero). However, knowledge of the lingering impacts of in utero heat stress on yearling dairy heifers is limited. Herein, we investigated the long-term effects of in utero heat stress on heifer growth, feed efficiency, and enteric methane emissions in post-pubertal heifers. During the last 56 d of gestation, 38 pregnant cows carrying heifer calves were exposed to either heat stress (IUHT; n = 17) or artificial cooling (IUCL; n = 21). At 18 ± 1 mo of age, the resulting IUCL and IUHT heifers were enrolled in the present 63-d study. Heifers were blocked by weight and randomly assigned to 3 pens with Calan gates. Body weights (BW) were recorded on 3 consecutive days at the start and end of the trial and used to calculate average daily gain (ADG). Body condition score (BCS), hip width, body length, and chest girth were measured at the start and end of the study. All heifers were fed a TMR comprised of 46.6% oatlage, 44.6% grass/alfalfa haylage, 7.7% male-sterile corn silage, 0.3% urea, and 0.8% mineral/vitamin supplement (DM basis). The TMR and refusal samples were obtained daily, composited weekly, and dried to calculate DMI. During the study, each pen had access to a GreenFeed unit for 8 ± 1d to measure CH4 and CO2 gas fluxes. During the last 3 d of measuring CH4 and CO2 fluxes, fecal samples were collected, composited by animal, dried, and analyzed to calculate NDF, OM, and DM digestibility. On the last day of fecal sampling, blood samples were also collected via coccygeal venipuncture, and gas chromatography time-of-flight mass spectrometry analysis was performed Residual feed intake (RFI; predicted DMI - observed DMI) and feed conversion efficiency (FCE; DMI/ADG) were calculated to estimate feed efficiency. No differences were found in initial or final BW, hip width, chest girth, or BCS; however, IUCL heifers were longer in body length compared with IUHT heifers. Dry matter intake, ADG, RFI, and FCE were similar between IUHT and IUCL heifers. In utero heat stressed and IUCL heifers produced similar amounts of CH4 and CO2, and no differences were found in the number of GreenFeed visits or latency to approach the GreenFeed. The concentrations of 6 blood metabolites involved in lipogenic pathways were different between in utero treatments. In conclusion, in utero heat stress does not seem to have long-term effects on feed efficiency or methane emissions during the post-pubertal growing phase; however, IUCL heifers maintained a body length advantage over their IUHT counterparts and differed in concentrations of several candidate metabolites that encourage further exploration of their potential function in key organs, such as the liver and mammary gland.

IJCM_340A: Eating Disorders And Its Associated Factors Among Medical Students Of A Government Medical College In Karnataka- A Cross Sectional Study

Background: Eating disorders are behavioral conditions characterized by severe and persistent disturbance in eating behaviors and associated distressing thoughts and emotions affecting physical, psychological, and social function. The high levels of stress affecting medical students predispose them to developing burnout and mental health problems, including eating disorders. Research and awareness efforts are crucial to understand and support the specific challenges faced by these students. Objective: To assess the prevalence of eating disorder and its associated factors among medical students a government medical college, Bengaluru. Methodology: A cross-sectional study was conducted among 200 students at a government medical college in Bengaluru. A stratified random sampling did from first year to fourth year medical students to select the study participants. The data was collected using a self-administered structured questionnaire, The Eating Attitudes Test (EAT-26), perceived stress scale (PSS) and Body Shape Questionnaire (BSQ-16B). We also calculated body mass index (BMI) for all the participants Results: 15% (30/200) of medical students were found to be at high risk for eating disorders. The prevalence of body shape concerns among the participants were found to be 28% (56/200). Eating disorders had statistically significant associations with female gender, severe body shape concerns and higher BMI (p value &lt;0.05). Conclusion: Eating disorders and body shape concerns are an emerging area of concern among medical students. The implementation of stress reduction and eating disorders preventive program during medical schools may be beneficial for the future physicians.

Autobiographical memory following weight gain in adult patients with Anorexia Nervosa: A longitudinal study.

Patients with anorexia nervosa (AN) show overgeneralization of memory (OGM) when generating autobiographical episodes related to food and body shape. These memories are central for the construction of a coherent self-concept, interpersonal relationships, and problem-solving abilities. The current study aims to investigate changes in autobiographical memory following weight gain. OGM was assessed with an adapted version of the Autobiographical Memory Test including food-, body-, depression-related, and neutral cues. N=41 female patients with AN (28 restricting-, 13 binge-eating/purging-subtype; mean disease duration: 4.5years; mean BMI: 14.5kg/m2) and N=27 healthy controls (HC) were included at baseline. After inpatient treatment (mean duration: 11weeks), 24 patients with AN and 24 age-matched HC were reassessed. Group differences were assessed using independent samples t-tests for cross-sectional comparisons and repeated measures ANOVAs for longitudinal data. At baseline, patients with AN generated significantly fewer specific memories than HC, independent of word category (F(1.66)=27.167, p<0.001). During inpatient stay, the average weight gain of patients with AN was 3.1 body mass index points. At follow-up, patients with AN showed a significant improvement in the number of specific memories for both depression-related and neutral cues, but not for food- and body-related cues. Generalised OGM (i.e., independent of word category) in patients with AN before weight restoration may be a general incapacity to recall autobiographical memory. After weight gain, the previously well-studied pattern of eating disorder-related OGM emerges. The clinical relevance of the continuing disorder-related OGM in patients with AN after weight gain is discussed.
