The impact of weight and negative body image on the body schema in undergraduate women.

BACKGROUND AND OBJECTIVES: Alterations of the sensory-motor body schema question the origins of such distortions. For example, in anorexia nervosa where patients think they are broader than they really are (body image) but act as if it was really the case (body schema). To date, the results of studies about what hinders the updating of the body schema so much (weight, body image) have been contradictory. METHODS: We therefore conducted two studies that aimed to assess the impact of weight and body image problems on body schema in 92 young women without anorexia nervosa. For this purpose, we used a new body schema assessment tool (SKIN) that is sensitive enough to detect fine alterations of body schema in seven different body parts. RESULTS: In Study 1, the thinness or overweight of the young women had a major impact on their tactile perception, especially because the assessed body part was a sensitive area for body dissatisfaction in young women (e.g., belly, thigh). In Study 2, the level of body dissatisfaction of the participants in its attitudinal and perceptual dimension also had a negative impact on their body schema, again in interaction with weight and body part. CONCLUSIONS: These results imply that body dissatisfaction and thinness are predictors of massive body schema distortions. An oversized body schema could maintain various weight-control behaviors, thus risking the development, maintenance, or relapse of an eating disorder.

Culturally Local Perspectives Are Imperative to Scientific Excellence and Health Equity in Eating Disorders Research: Commentary on Monocello et al. (2024).

This commentary discusses a principal contribution of Monocello et al.'s paper presenting a cultural models approach to body fatness perceptions, which provides a rigorous and systematic means of identifying analytic categories that are locally meaningful, in contrast to categories derived from a solely universalizing perspective. In situating their work within an underrepresented population in eating disorders research-young men in South Korea-the authors step beyond the constraints of a universalizing, or etic, framework for probing how body dissatisfaction relates to eating disorder risk. The value of an alternative analytic framework, based on a culturally local, or emic, perspective on how bodies are perceived is demonstrated through the use of a cultural models approach exploring the relationship between culturally defined conceptualizations of body image and eating disorder risk. Understanding such relationships and the meanings attributed to the myriad aspects of body image through locally grounded frameworks provides an essential tool for investigators and clinicians to better understand the lived experience of body dissatisfaction and disordered eating, and also to inform more culturally salient approaches to diagnosis, treatment, and prevention. An emic approach that centers local perspectives and priorities also facilitates participation of communities underrepresented in research in knowledge production.

A Call for More Culture-Based Research to Understand Body Dissatisfaction and Disordered Eating in Men: Commentary on Monocello et al. (2024).

Using culture-based approaches, Monocello et al. revealed that young Korean men generally shared the same perceptions of fatness, including three categories ("too thin," "balanced," and "too fat"). The "balanced" category was most consistent with local South Korean culture, and the "too fat" category was associated with higher body dissatisfaction and disordered eating. Even though cultural differences in body ideals are an essential factor to consider in the development of body dissatisfaction and disordered eating, little research has applied culture-based approaches to explore body ideals in men, including how these ideals may be related to men's body image or eating behaviors. Thus, Monocello et al.'s work is a timely and vital contribution to the literature. In this commentary, we expand on Monocello et al.'s work by not only illustrating the roles of local cultures but also introducing the potential influences of external cultures via acculturation in shaping body ideals which, in turn, contribute to body dissatisfaction and disordered eating in men. We also provide future research directions to call for more culture-based research to understand body dissatisfaction and disordered eating among men in different cultural contexts.

Beyond Age, BMI, Gender Identity, and Gender Minority Stress, Weight Bias Internalization Is Uniquely Associated With More Eating and Body Image Disturbances and Poor Physical and Mental Health in Chinese Gender-Diverse Adults.

OBJECTIVE: Weight bias internalization (WBI) is a robust, positive correlate of negative health outcomes; however, this evidence base primarily reflects cisgender individuals from Western cultural contexts. Gender-diverse individuals from non-Western cultural contexts (e.g., China) are at potentially high risk for WBI. Yet, no research has examined WBI and associated negative health consequences in this historically underrepresented population. METHOD: A cross-sectional, online survey sampled Chinese gender-diverse individuals (N = 410, Mage = 22.33 years). Variables were self-reported, including demographics, WBI, body shame, body dissatisfaction, disordered eating, physical and mental health status, and gender minority stress (e.g., internalized cisgenderism). Analyses included correlations and multiple hierarchical regressions. RESULTS: Pearson bivariate correlations demonstrated associations between higher WBI and more eating and body image disturbances and poor physical and mental health. After adjusting for age, BMI, gender identity, and gender minority stress, higher WBI was uniquely and positively associated with higher body shame, higher body dissatisfaction, higher disordered eating, and poor physical and mental health. Notably, WBI accounted for more unique variance in eating and body image disturbances (13%-25% explained by WBI) than physical and mental health (1%-4% explained by WBI). DISCUSSION: While replication with longitudinal and experimental designs is needed to speak to the temporal dynamics and causality, our findings identify WBI as a unique, meaningful correlate of eating and body image disturbances in Chinese gender-diverse adults.

Exploring longitudinal relationships between fitness tracking and disordered eating outcomes in college-aged women.

OBJECTIVE: A growing body of research, primarily cross-sectional, suggests a relationship between the practice of tracking one's food intake and exercise behaviors using fitness-tracking smartphone applications ("apps") or wearable devices ("wearables") and disordered eating symptomatology. The aim of the present study was to explore longitudinal relationships between fitness tracking and disordered eating outcomes among college-aged women, as well as to determine whether the individual-level risk factors of pre-existing eating concerns, perfectionism, and rumination about food moderated the relationship. METHOD: N = 68 female undergraduates used the MyFitnessPal app for 8 weeks while completing a series of self-report measures. RESULTS: At the trait level, fitness tracking frequency was positively associated with weight/shape concerns, but not with the other outcome measures. Daily levels of fitness tracking did not predict next-day levels for any of the outcome measures. Within-day fitness tracking at one timepoint was associated with lower reports of dietary restraint efforts at the next timepoint. None of the proposed moderators significantly interacted with the relationships over time. DISCUSSION: These results suggest that while those who engage in fitness tracking may experience higher weight/shape concerns as a trait, over time fitness tracking was not associated with an increase in concerns. Further work exploring whether fitness tracking may affect particular subgroups in different ways is warranted.

Associations Between Negative Body Image and Sexual Health Practices in Emerging Adults from Malaysia.

Past findings on the association between negative body image and sexual health behaviors have been mixed and mostly derived from Western samples. The aim of the current study was to examine associations between indices of negative body image and sexual health practices that reduce the risk of disease transmission in emerging adults, and whether these associations are moderated by gender. Using an online survey, a convenience sample of 584 Malaysian adults aged 18-30 years (230 men, 354 women) completed measures of satisfaction with overall appearance, body size dissatisfaction, weight satisfaction, height satisfaction, and genital image evaluation. They also reported if they ever had partnered sex, condomless sex, and been screened for human immunodeficiency virus (HIV), as well as their lifetime number of penetrative sex partners. Hierarchical logistic and ordinal regression analyses indicated that more positive genital image evaluation, but not the other body image indices, was significantly associated with having had partnered sex and fewer lifetime penetrative sex partners. None of the body image indices were significantly associated with condomless sex. All associations were consistent across men and women. For HIV testing, a significant interaction between genital image evaluation and gender emerged. However, this was reduced to non-significance after controlling for the number of penetrative sex partners. Overall, our findings underline the importance of promoting improved genital image in interventions aimed at increasing positive sexual health behaviors.

Differences in Thinness- and Muscularity-Oriented Eating and Body Image Disturbances and Psychosocial Well-Being in Chinese Sexual Minority Men Reporting Top, Bottom, and Versatile Sexual Self-Labels.

In addition to describing sexual partner preferences, sexual self-labels in gay and bisexual (henceforth, sexual minority) men, such as top, bottom, and versatile, are associated with psychological characteristics (e.g., gendered personality traits). No research has explored the association between sexual self-labels and eating and body image disturbances in sexual minority men. Research in sexual minority men from China is particularly valuable and needed due to recent rises in rates of eating and body image disturbances and unique, minority-specific stressors experienced by Chinese sexual minority populations. We adopted an online, cross-sectional study in a sample of sexual minority men from China (N = 403; tops, n = 256, bottoms, n = 95, versatiles, n = 52). Bottoms reported higher thinness internalization, lower muscularity internalization, higher body fat dissatisfaction, and higher psychological distress than tops. Bottoms' weight bias internalization was higher than tops' and versatiles' reports and, compared to versatiles, bottoms also reported higher psychosocial impairment related to eating disorder psychopathology. Compared to versatiles, tops reported higher drive for muscularity and muscularity-oriented disordered eating. Adjusting for age, psychological distress, and psychosocial impairment, tops reported higher muscularity internalization than bottoms and higher drive for muscularity and muscularity-oriented disordered eating than both bottoms and versatiles. Findings suggested unique relations between sexual self-labels and eating and body image disturbances in Chinese sexual minority men. Replication and validation of the temporal order between sexual self-labels and eating and body image disturbances is needed, including assessment of social factors (e.g., femmephobia, minority stress) that may help explain the links between sexual self-labels and eating pathology.

Determinants of Dissatisfaction After Laparoscopic Cure of Vaginal and/or Rectal Prolapse using Mesh: a Comprehensive Retrospective Cohort Study.

INTRODUCTION AND HYPOTHESIS: The primary objective is to identify determinants of dissatisfaction after surgical treatment of vaginal prolapse ± rectal prolapse, using laparoscopic mesh sacrohysteropexy (LSH) or sacrocolpopexy (LSC) ± ventral mesh rectopexy (VMR). The secondary objective is the evaluation of complications and objective/subjective recurrence rates. METHODS: The study performed was a single-surgeon retrospective review of prospectively collected data. LSH/LSC ± VMR were performed between July 2005 and September 2022. Primary investigated outcome was patients' satisfaction, assessed using the Patient Global Impression of Improvement (PGI-I) score and the bother visual analog scale (VAS) obtained postoperatively (at a 1-month interval and on a 6-month/yearly basis thereafter). We looked for a correlation between the level of satisfaction (as reflected by the VAS) and potential determinants. RESULTS: There were 355 patients with a mean age of 62 ±12 years. Nearly all the patients (94.3%) had a stage 3 or 4 prolapse according to the POP-Q classification. The mean postoperative bother VAS was 1.8, with only 12.7% of patients reporting a bother VAS score ≥ 3/10, indicating a dissatisfaction. PGI-I showed improvement in the vast majority of patients (96.4% scoring 1 to 3). Patients with anal incontinence preoperatively scored higher on the bother VAS postoperatively (r=0.175, p < 0.05). The use of a posterior arm mesh (for posterior vaginal prolapse) correlated with better satisfaction overall (r= -0.178, p = 0.001), whereas the performance of VMR was associated with a bothering sensation (r = 0.232, p < 0.001). A regression analysis confirmed the impact of posterior mesh and VMR on satisfaction levels, with odds of dissatisfaction being 2.18 higher when VMR was combined with LSH/LSC. CONCLUSIONS: Posterior mesh use improves patient satisfaction when the posterior compartment is affected. In patients with concomitant vaginal and rectal prolapse, combining VMR with anterior LSC/LSH appears to negatively impact patients' satisfaction. Preoperative anal incontinence was demonstrated to be a risk factor for postoperative dissatisfaction.

Addressing nutritional issues and eating behaviours among university students: a narrative review.

University life is a critical period for establishing healthy eating habits and attitudes. However, university students are at risk of developing poor eating habits due to various factors, including economic conditions, academic stress and lack of information about nutritional concepts. Poor diet quality leads to malnutrition or overnutrition, increasing the risk of preventable diseases. Food environments on university campuses also play a significant role in shaping the dietary habits of students, with the availability of and accessibility to healthy food options being important factors influencing food choices and overall diet quality. Disordered eating habits and body dissatisfaction are prevalent among university students and can lead to eating disorders. Income and living arrangements also influence dietary habits, with low household income and living alone being associated with unhealthy eating habits. This study is a narrative review that aimed to address nutritional issues and eating behaviours, specifically among university students. We investigated the eating behaviours of university students, including their dietary patterns, food choices and food environments. The objective of this review was to provide insights into the nutritional issues and eating behaviours of university students, with the aim of identifying target areas for intervention to improve the overall health and wellbeing among college students. University food environments need to be restructured to promote healthy eating, including the availability, accessibility, affordability and labelling of healthy foods, and policies to limit the availability of unhealthy foods and drinks on campus.

Dissatisfaction-considered waiting time prediction for outpatients with interpretable machine learning.

Long waiting time in outpatient departments is a crucial factor in patient dissatisfaction. We aim to analytically interpret the waiting times predicted by machine learning models and provide patients with an explanation of the expected waiting time. Here, underestimating waiting times can cause patient dissatisfaction, so preventing this in predictive models is necessary. To address this issue, we propose a framework considering dissatisfaction for estimating the waiting time in an outpatient department. In our framework, we leverage asymmetric loss functions to ensure robustness against underestimation. We also propose a dissatisfaction-aware asymmetric error score (DAES) to determine an appropriate model by considering the trade-off between underestimation and accuracy. Finally, Shapley additive explanation (SHAP) is applied to interpret the relationship trained by the model, enabling decision makers to use this information for improving outpatient service operations. We apply our framework in the endocrinology metabolism department and neurosurgery department in one of the largest hospitals in South Korea. The use of asymmetric functions prevents underestimation in the model, and with the proposed DAES, we can strike a balance in selecting the best model. By using SHAP, we can analytically interpret the waiting time in outpatient service (e.g., the length of the queue affects the waiting time the most) and provide explanations about the expected waiting time to patients. The proposed framework aids in improving operations, considering practical application in hospitals for real-time patient notification and minimizing patient dissatisfaction. Given the significance of managing hospital operations from the perspective of patients, this work is expected to contribute to operations improvement in health service practices.

Effects of linear periodized and non-periodized combined training on body image perception of adults with obesity: A randomized clinical trial.

OBJECTIVE: Verify the effect of non-periodized and linear periodized combined training on body image perception and body dissatisfaction in adults with obesity. DESIGN: A randomized clinical trial on the effect of two types of combined training periodization was carried out on people with grade I and II obesity. SETTING: Participants were allocated into three groups: non-periodized periodization group, linear periodization group, and control group, with 23 participants in each. SUBJECTS: Adults with obesity, with a body mass index between 30 kg/m² and 40 kg/m². INTERVENTIONS: The intervention lasted 16 weeks (separated into three mesocycles of 4 weeks and 1 week of familiarization), in 3 weekly sessions of 1 hour each, composed of aerobic (30 min) and muscle strength exercises (six exercises) in the same session. The group with non-periodized model maintained uniform intensity, volume, and workload throughout the mesocycles. The group with the linear periodization model started with low initial intensity, subsequently introducing a gradual increase of intensity in the mesocycles. MAIN MEASURES: Body image perception (current and ideal silhouette) and body dissatisfaction were assessed using the Stunkard silhouette scale. RESULTS: The perception of the current silhouette increased only in the control group (Δ = 1.16; p = 0.04). There was a significant reduction in the ideal silhouette over time (p = 0.001), especially in non-periodized group (Δ = -1.26). Body dissatisfaction increased significantly only over time (p = 0.001), especially for control group (Δ = 1.47). CONCLUSIONS: Regardless of periodization, combined training effectively maintained the perception of the current silhouette and reduced the ideal silhouette in adults with obesity. TRIAL REGISTRATION: Brazilian Registry of Clinical Trials (RBR-3c7rt3).

Body dissatisfaction and beyond: Investigating attitudes towards calorie labels on UK food menus.

In 2022 the British government made calorie labels on menus a legal requirement to encourage healthier food choices while dining out. Yet, little research has explored perceptions of calorie labels on menus in the United Kingdom or tested whether there may be groups of people vulnerable to potential negative effects of calorie labels, such as those with body dissatisfaction. This between-subjects, convergent mixed-methods study addressed these enquiries. Participants were 562 adults who completed an online survey where hypothetical food orders were made from a menu. The study found that participants who viewed a menu with calorie labels ordered fewer calories. Quantitative results did not find that participants with higher levels of body dissatisfaction were at significantly greater odds of using calorie labels to order fewer calories. However, our qualitative (thematic) analysis revealed that experiences of calorie labels could be shaped by body image concerns. Themes further drew on how calorie labels were empowering, but there were also concerns about their oversimplicity. Findings are discussed in relation to implications for future calorie labelling policies. Given the inconsistent findings amongst the limited amount of literature investigating the role of body dissatisfaction in how calorie labels are used, future research is crucial. In the meantime, as a cautionary measure, clinicians involved in supporting individuals with body or food-related concerns should be aware of the challenges their clients may experience in facing calorie labels on menus when dining out.

Exposure to Instagram junk food content negatively impacts mood and cravings in young adults: A randomized controlled trial.

Exposure to different types of images on social media is known to affect physical and mental wellbeing including changes in perception of body image (BI) and dietary behavior. The present study aimed to assess the effects of junk food-related Instagram content exposure on body image, overall mood, and cravings in young adults. A randomized crossover experimental design was used. After filling out a baseline survey, participants (n = 63, aged 18-24) browsed either a control Instagram account feed or an account rich in junk food images during 15 min. They then filled a short survey evaluating their state BI, mood, and cravings (T1). After a 1-week washout period (T2), participants browsed the other account type followed by the same short survey as in T1. Results showed that exposure to junk food content was associated with increased feelings of hunger, stress, sadness, and exhaustion, in addition to higher salty, savory, and fatty food cravings. Moreover, participants showed higher desire for junk food and lower desire for healthy food items from a virtual food tray after junk food content exposure. There was no impact of content type on state BI dissatisfaction. In conclusion, exposure to junk-food related content on social media negatively affects mood and cravings, subsequently influencing food choices. The present findings shed light on the need for interventions aimed at providing cognitive and emotional competencies for enhancing media literacy and promoting mindful social media use.

Passive social networking sites use and disordered eating behaviors in adolescents: The roles of upward social comparison and body dissatisfaction and its sex differences.

Previous research has indicated a link between social networking site (SNS) use and eating behaviors, but the underlying mechanisms have not been well explored. This study investigated the role of upward social comparison and body dissatisfaction in the relationship between passive SNS use and disordered eating (DE) behaviors, as well as sex differences. A total of 744 middle school students (51.6% female, Mage = 12.87 years, SD = 0.68) completed self-report questionnaires regarding passive SNS use, upward social comparison, body dissatisfaction, and DE behaviors. Results revealed that: 1) girls reported significantly higher levels of passive SNS use, body dissatisfaction, and DE behaviors than boys; 2) passive SNS use was a significant predictor of DE behaviors both sexes; 3) body dissatisfaction mediated the relationship between passive SNS use and DE behaviors for girls; 4) the chain mediating effects of upward social comparison and body dissatisfaction between passive SNS use and DE behaviors were found only among adolescent girls; 5) Compared to boys, body dissatisfaction in girls is more significantly related to DE behaviors, and upward social comparison is more closely related to body dissatisfaction in girls. These findings suggest that passive SNS use, rather than general SNS use, was related to body dissatisfaction and eating concerns. Interventions targeting specific passive SNS users may be an effective avenue for the prevention and management of body-related concerns and disordered eating behavior in adolescent girls.

Eating disorder symptom dimensions and protective factors: A structural network analysis study.

Eating Disorders (EDs) and related symptoms pose a substantial public health concern due to their widespread prevalence among both genders and associated negative outcomes, underscoring the need for effective preventive interventions. In this context, deepening our understanding of the interplay between ED symptoms and related protective factors appears crucial. Therefore, this study employed a structural network analysis approach considering both ED symptom dimensions (i.e., drive for thinness, bulimic symptoms, and body dissatisfaction) and related protective factors (i.e., body and functionality appreciation, intuitive eating, and self-esteem) to shed light on how these factors are interrelated. A community sample of 1391 individuals (34.4% men; Mage = 26.4 years) completed a socio-demographic schedule and self-report questionnaires. The network showed that the nodes with the highest positive expected influence were body and functionality appreciation, while those with the highest negative expected influence were eating for physical rather than emotional reasons and unconditional permission to eat (i.e., two components of intuitive eating). Crucially, the most relevant bridges between the conceptual communities "ED symptom dimensions" and "Protective factors" were the negative relations between (a) eating for physical rather than emotional reasons and bulimic symptoms, (b) unconditional permission to eat and drive for thinness, and (c) body appreciation and body dissatisfaction. Finally, age, gender, and body mass index did not moderate any edge in the network. The practical implications of these findings are discussed, especially in terms of preventive interventions for ED symptoms.

Beyond medical errors: exploring the interpersonal dynamics in physician-patient relationships linked to medico-legal complaints.

BACKGROUND: Previous research suggests that medico-legal complaints often arise from various factors influencing patient dissatisfaction, including medical errors, physician-patient relationships, communication, trust, informed consent, perceived quality of care, and continuity of care. However, these findings are not typically derived from actual patients' cases. This study aims to identify factors impacting the interpersonal dynamics between physicians and patients using real patient cases to understand how patients perceive doctor-patient relational problems that can lead to dissatisfaction and subsequent medico-legal complaints. METHODS: We conducted a retrospective study using data from closed medical regulatory authority complaint cases from the Canadian Medical Protective Association (CMPA) between January 1, 2015, and December 31, 2020. The study population included patients who experienced sepsis and survived, with complaints written by the patients themselves. A multi-stage standardized thematic analysis using Braun and Clarke's approach was employed. Two researchers independently coded the files to ensure the reliability of the identified codes and themes. RESULTS: Thematic analysis of 50 patient cases revealed four broad themes: (1) Ethics in physician's work, (2) Quality of care, (3) Communication, and (4) Healthcare system/policy impacting patient satisfaction. Key sub-themes included confidentiality, honesty, patient involvement, perceived negligence, perceived lack of concern, active engagement and empathy, transparency and clarity, informed consent, respect and demeanor, lack of resources, long wait times, and insufficient time with physicians. CONCLUSIONS: This study identifies and categorizes various factors impacting relational issues between physicians and patients, aiming to increase patient satisfaction and reduce medico-legal cases. Improving physicians' skills in areas such as communication, ethical practices, and patient involvement, as well as addressing systemic problems like long wait times, can enhance the quality of care and reduce medico-legal complaints. Additional training in communication and other skills may help promote stronger relationships between physicians and patients.

Association Between Body Image Before and During Pregnancy and Gestational Weight Gain in Japanese Women: A Prospective Cohort Study.

OBJECTIVES: More than half of women do not achieve appropriate gestational weight gain. Maternal body image may be an important factor associated with gestational weight gain. However, this association has not been thoroughly evaluated. We aimed to elucidate whether body image parameters before and during pregnancy are associated with gestational weight gain in Japanese women. METHODS: This prospective cohort study was conducted at a hospital in Osaka, Japan from March 2020 to March 2021. We recruited women with singleton pregnancies in their second and third trimesters. Body image was assessed using the Pregnancy and Weight Gain Attitude Scale and additional questions. Gestational weight gain was classified as insufficient, appropriate, or excessive based on recommended ranges in Japan. One-way analysis of variance, chi-square tests, and multinomial logistic regression analyses were performed to identify factors associated with insufficient or excessive weight gain. RESULTS: Of 266 enrolled women, 47 had insufficient weight gain and 100 had excessive weight gain during pregnancy. Risk factors for excessive gestational weight gain included a history of dietary restriction before pregnancy, negative attitudes toward gestational weight gain, and perception of body shape as fat and body shape dissatisfaction during pregnancy. Perception of body shape as thin during pregnancy was identified as a risk factor for insufficient gestational weight gain. CONCLUSIONS: Body image before and during pregnancy may be an important factor in preventing insufficient or excessive gestational weight gain in Japanese women. Healthcare professionals should consider body image when providing health guidance on weight management to pregnant women.

Exploring the Relationship Between Instagram Use and Self-Criticism, Self-Compassion, and Body Dissatisfaction in the Spanish Population: Observational Study.

BACKGROUND: The widespread use of online social networks, particularly among the younger demographic, has catalyzed a growing interest in exploring their influence on users' psychological well-being. Instagram (Meta), a visually oriented platform, has garnered significant attention. Prior research has consistently indicated that Instagram usage correlates with heightened levels of perfectionism, body dissatisfaction, and diminished self-esteem. Perfectionism is closely linked to self-criticism, which entails an intense self-scrutiny and is often associated with various psychopathologies. Conversely, self-compassion has been linked to reduced levels of perfectionism and stress, while fostering greater positive affect and overall life satisfaction. OBJECTIVE: This study investigates the relationship between Instagram usage (time of use and content exposure) and users' levels of self-compassion, self-criticism, and body dissatisfaction. METHODS: This study comprised 1051 adult participants aged between 18 and 50 years, either native to Spain or residing in the country for at least a decade. Each participant completed a tailored questionnaire on Instagram usage, along with abbreviated versions of the Self-Compassion Scale, the Body Shape Questionnaire, and the Depressive Experiences Questionnaire, spanning from January 23 to February 25, 2022. RESULTS: A positive correlation was observed between daily Instagram usage and self-criticism scores. Participants of all age groups who spent over 3 hours per day on Instagram exhibited higher self-criticism scores than users who spent less than 1 hour or between 1 and 3 hours per day. Contrary to previous findings, no significant relationship was detected between Instagram usage time and levels of self-compassion or body dissatisfaction. Furthermore, content centered around physical appearance exhibited a positive correlation with self-criticism and body dissatisfaction scores. Among younger participants (aged 18-35 years), those who primarily viewed beauty or fashion content reported higher self-criticism scores than those consuming science-related content. However, this association was not significant for participants aged 35-50 years. Conversely, individuals who predominantly engaged with sports or fitness or family or friends content exhibited higher levels of body dissatisfaction than those focusing on science-related content. No significant associations were observed between self-compassion scores and daily Instagram usage or most-viewed content categories. CONCLUSIONS: The findings of this study underscore the considerable impact of Instagram usage on self-criticism and body dissatisfaction-2 variables known to influence users' psychological well-being and be associated with various symptoms and psychological disorders.

Body dissatisfaction and dieting among Finnish adolescents: a 20-year population-based time-trend study.

Body image has an important role in the health and development of adolescents. Body dissatisfaction and dieting can become chronic and continue into adulthood. There is a lack of recent, comprehensive studies on ongoing trends on body dissatisfaction. This study assessed time-trend changes in self-reported body dissatisfaction and dieting among Finnish adolescents at four assessment points. Representative samples of adolescents (N = 6660) aged 13-16 years participated in school-based, cross-sectional studies in 1998 (N = 1458), 2008 (N = 2044), 2014 (N = 1809), and 2018 (N = 1349), respectively. The studies were similar in design, methodology, and geographical recruitment areas. Body dissatisfaction and dieting were assessed with a questionnaire including items derived from the DSM-IV criteria for anorexia and bulimia nervosa. From 1998 to 2018, dieting and fears related to gaining weight decreased among females. Body dissatisfaction reduced among females, and their wishes to become thinner became less prevalent. Consuming large amounts of food at one time consistently decreased among females and males and there were no changes in the rates of willful vomiting. The number of females in the 90th percentile with the most severe symptoms decreased. The results indicate that body dissatisfaction and disturbed dieting improved among females during the 20-year study. Despite these positive developments, the overall level of symptoms among females remained substantial, indicating that females have much higher levels of body dissatisfaction and dieting than males.

Eating Disorder Symptomatology Among Young Adult Cigarette and E-Cigarette Users.

Objective: Tobacco use is elevated among individuals with eating disorders (EDs). Yet, further research is needed to understand associations between cigarette and e-cigarette use patterns and ED symptomatology. To gain a more comprehensive understanding of tobacco use and EDs, this study characterized ED symptomatology and tobacco use patterns, including exclusive cigarette use, e-cigarette use, dual use, and nonuse. Method: Young adults aged 18-24 years who self-reported exclusive cigarette, e-cigarette, dual, or nonuse (N = 2500) were recruited via Lucid, an online survey management company. Participants completed questionnaires assessing body dissatisfaction, global ED psychopathology, binge eating and self-induced vomiting frequency, and demographics. ED diagnostic groups included: anorexia nervosa (AN), bulimia spectrum eating disorders (BSED), atypical AN, and night eating syndrome (NES). Results: Multinomial logistic models revealed those with AN were more likely to be dual users, those with atypical AN were more likely to be exclusive e-cigarette users, and participants with a BSED or NES were more likely to be exclusive e-cigarette or dual users, compared to those without an ED. General linear models suggested body dissatisfaction and global ED psychopathology were higher among exclusive e-cigarette and dual users, while binge eating and self-induced vomiting frequencies were greater among all tobacco use groups compared to nonusers. Discussion: Our findings suggest young adults with ED symptomatology were more likely to be users of e-cigarettes exclusively or dual users. It will be necessary to examine how these associations manifest using longitudinal and clinical populations in future research.
