A Review of the Literature Lacie L Parker and Harriger Journal of Eating Disorders (2020) 8:51 https://doi.org/10.1186/s40337-020-00327-y REVIEW Open Access Eating disorders and disordered eating behaviors in the LGBT population: a review of the literature Lacie L. Parker1* and Jennifer A. Harriger2 Abstract Background: According to past research, lesbian, gay, bisexual, and transgender (LGBT) individuals experience a higher prevalence of psychopathology, which is attributable to the increased stress (i.e., stigma and prejudice) that they experience, as detailed by the minority stress model (MSM). Main: This current literature review examined the empirical literature regarding the rates and types of, and risk factors for eating disorders and disordered eating behaviors in LGBT adults and adolescents, in addition to each individual subgroup (i.e., lesbians, gay males, bisexuals, transgender and gender-nonconforming individuals). Conclusion: LGBT adults and adolescents experience greater incidence of eating disorders and disordered eating behaviors than their heterosexual and cisgender counterparts. Additionally, gay, bisexual, and transgender adults and adolescents were all at increased risk for eating disorders and disordered eating behaviors. Mixed results were found for lesbian adults and adolescents. Results are discussed within the framework of the MSM.

    Eating Disorders – A Current Affair An Introduction An expanded introduction to National Eating Disorder Publications: An Integrated Response to Complexity National Eating Disorders Framework 2012 Clarity in Complexity Strategic Communication to Support the Prevention and Early Identification of Eating Disorders Eating disorders are a priority mainstream health issue in Australia Eating disorders are highly complex and serious mental illnesses within our community. They include Anorexia Nervosa, Bulimia Nervosa, Binge Eating Disorder, and Eating Disorder Not Otherwise Specified (EDNOS)1. These disorders are associated with a high level of morbidity and mortality; in fact Anorexia Nervosa has the highest rate of mortality of any psychiatric illness. They can be long- term, disabling disorders, and they carry substantial costs – economic, social and loss of life. As serious mental disorders with significant consequences for physical health and quality of life as well as mental health, eating disorders require the same quality, breadth and accessibility to research funding, prevention interventions, treatment options, and community awareness programs as other serious physical or mental illnesses. Eating Disorders have a significant and highly underestimated impact on Australian society: Physically, as well as mentally, the person with the eating disorder is profoundly affected. Eating disorders involve wide-ranging medical complications which can affect every major organ in the body. In children and adolescents, eating disorders can affect

Sicignano The City College of New York SOMATIC DEPRESSION AND EATING DISORDERS 2 Abstract Depression is known to affect females in much greater numbers than males, with about three times as many women having the disorder as men (American Psychiatric Association, 2013). A similar gender disparity can be seen in eating disorders, where up to nine in ten sufferers are female (American Psychiatric Association, 2013). Studies have shown that most of the gender difference in depression occurs as a result of women experiencing a form of depression involving a number of body-centric symptoms, including headaches, weight changes, fatigue, and insomnia, which has been termed “somatic depression” (Silverstein et al., 2013). Some of the symptoms, such as a fear of becoming fat, restricting or binging, and an abnormal focus on shape, are also characteristic of eating disorders (American Psychiatric Association, 2013).

  • Intermittent Fasting Diets and Disordered Eating
    Protection, risk and dieting: Intermittent fasting diets and disordered eating Jasmin Langdon-Daly D.Clin.Psy. Thesis (Volume 1) 2016 University College London UCL Doctorate in Clinical Psychology Thesis declaration form I confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Signature: Name: Jasmin Langdon-Daly Date: 09.06.16 2 Overview Consideration of factors and behaviours which may increase the risk of disordered eating, or protect against these difficulties and promote resilience, can inform efforts to prevent and intervene. Part One of this thesis is a systematic review of research into protective factors against eating disorders and disordered eating in proximal social systems. A range of potential protective factors in families, schools, peer groups and neighbourhoods are identified. Many of these factors may be non-specific to eating difficulties, promoting a range of positive outcomes, while others may be more specific to disordered eating. Methodological issues in the literature which limit the ability to draw firm conclusions are discussed. Part Two presents empirical research into the impact of intermittent fasting (IF) diets on eating psychopathology, binge eating, food craving and mood. Contrary to expectation, starting a 5:2 IF diet did not result in increases in disordered eating or binge eating in healthy adult dieters, and in fact appeared to result in improvements in all outcomes. Higher scores on measures of risk factors for eating disorders at baseline were associated with greater reductions in disordered and binge-eating over the 28 day IF period.

  • Body Image Perception Among Undergraduate Females As It Relates to Disordered Eating and Depressive Symptoms
    Body Image Perception of Undergraduate Females as it Relates to Disordered Eating and Psychological Conditions Natalie Swierkosz Project Advisor: Dr. Jill Clutter Co-advisor: Dr. Chris Taylor Undergraduate Honors Thesis School of Allied Medical Professions The Ohio State University Abstract Objectives: The purpose of this research was to determine the accuracy of body image perception among domestic undergraduate women at four-year universities. Analysis was also performed to determine if women who overestimated body mass index (BMI) would be more likely to report the desire to lose weight and what behaviors they were using to do so, as well as if they were more likely to experience psychological disorders such as depression and anxiety. Previous research suggests that undergraduate females with a negative body image are at high risk for developing patterns of disordered eating and psychological conditions. Methods: This was a retrospective cross-sectional study. Data was obtained through the American College Health Association and was analyzed using the Statistical Package for Social Sciences (SPSS v 17.0). Data came from participants in the 2005 National College Health Assessment. For All males, graduate students, and international students were excluded in order to isolate the target population. Results: Results indicated that the majority of undergraduate females have an accurate body image perception. However, those women who overestimated their actual body weight were much more likely to express the desire to lose weight than those with accurate perception or those who underestimate. Women who perceive themselves as being heavier than they truly are were more likely to report taking action to lose weight, including partaking in unhealthy behaviors such as vomiting and taking diet pills.

  • Depression, Anxiety and Eating Disorder-Related Impairment: Moderators in Female Adolescents and Young Adults
    International Journal of Environmental Research and Public Health Article Depression, Anxiety and Eating Disorder-Related Impairment: Moderators in Female Adolescents and Young Adults Johanna Sander * , Markus Moessner and Stephanie Bauer Center for Psychotherapy Research, Heidelberg University Hospital, 69115 Heidelberg, Germany; [email protected] (M.M.); [email protected] (S.B.) * Correspondence: [email protected]; Tel.: +49-6221-5638170 Abstract: Adolescents and young adults, particularly females, are highly vulnerable to the develop- ment of anxiety disorders, depression, and eating disorders. Comorbid anxiety disorder or depression in eating disorders are associated with greater symptom severity, poorer prognosis, and burden of illness. Nonetheless, studies on what affects the relationship between anxiety, depression, and eating disorders in female at-risk samples are scarce. Using hierarchical linear modeling, the present study examined potential moderators to explain between-person differences in the association between anx- iety, depression, and eating disorder-related impairment within 12- to 25-year-old females (N = 320). High impairment in anxiety/depression was associated with more severe eating disorder symptoms. Older age as well as greater impairment in mood dysregulation, self-esteem, and perfectionism were linked to more severe eating disorder symptomatology. Whereas mood dysregulation, self-esteem, and perfectionism had no statistically significant moderating effects, younger age appeared to aug- ment the association of anxiety/depression and eating disorder symptomatology. Preventive care in particular needs to consider age-related effects as eating disorder symptoms are associated more Citation: Sander, J.; Moessner, M.; strongly with symptoms of anxiety and depression in early adolescence.

  • 'Depression Meals': How Diets Connect to Mental Health
    ‘Depression meals’: How diets connect to mental health By Meghan Collie National Online Journalist, Smart Living & Entertainment Global News Catherine was formally diagnosed with depression at 13 years old and anxiety at 17. Both have severely impacted her relationship with food. “When I’m in a depressive episode, I tend towards disordered eating,” she told Global News. “Maybe I’ll have one meal instead of three. [I often] eat too much or too little.” Catherine, whose last name has been withheld to protect her identity, also works as a line cook. “I spend all day cooking for other people [and] I find it really hard to take care of myself in the same way,” she said. When she feels depressed, she tends to opt for things like a handful of crackers or ordering a pizza — “something that requires little to no food prep.” “My ‘depression meal’ a lot of the time is ordering food out, but because that’s expensive, I also eat a lot of cereal.” Catherine believes the food she eats when she’s depressed, which typically lacks any real nutrition, reinforces her symptoms, furthering her depression and contributing to poor health overall. “I feel noticeably better when I eat something good and healthy, but it’s really tough to find the spoons to do that sometimes,” she said. “The junk food makes me feel worse.” It’s more common for people with depression to experience a decrease in appetite, but research also shows that as many as 35 per cent of people may experience an increase, said Dr.

Read Full License Page 1/12 Abstract Purpose Evidence suggests that the harm avoidance personality type is more common among individuals with night eating syndrome (NES) than in the general population. Evidence of associations with other personality traits is limited. The current study investigated the association between a range of personality traits and NES. Methods Cross-sectional data were used from women with bulimia nervosa or binge eating disorder referred for treatment in an outpatient psychotherapy trial. Regression analyses were used to test associations between personality traits (measured with the Temperament and Character Inventory-Revised) and NES symptoms (measured with the Night Eating Questionnaire), adjusting for potential confounding variables. Results The sample included 111 women. Low cooperativeness scores were associated with greater NES symptoms in the multivariable model (mean difference: -.10, 95% condence intervals: -.20 to -.01, p = 0.033). There was weak evidence of associations between both high harm avoidance and low self-directedness personality traits and greater NES symptoms.

  • Disordered Eating in Athletes
    PHYSICIAN PERSPECTIVE Tracy Ray, MD, Column Editor Disordered eating in Athletes Salvador O. Montenegro, MD • American Sports Medicine Institute ANY RECENT STUDIES have demonstrated a higher incidence of eating Mdisorders among athletes than among nonathletes.1-4 The prevalence of disordered eating, unhealthy dieting, and distorted body image has been reported to range from 12% to 57%.4 One study revealed that 20% of females and 8% of males met Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria for anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified, compared with 9% and 0.5% for nonathletic females and males, respectively.5 Over one third of athletes have reported to use at least one extreme dieting method, 51% have tried to lose weight in the past month, and 77% want to lose weight. Questions about dieting and weight reduction among athletes are com- monplace. Early warning signs can be identified when athletes complete their preparticipation physical-exam forms. Athletic trainers are often the first to detect eating disorders in athletes and should become familiar with the signs, symptoms, and multiple diagnostic tools available. Since the introduction of Title IX in the early 1970s the number of female college athletes has increased by more than 500%.6 Many stud- ies have reported a higher incidence of eating disorders among female athletes than among males.7-10 Athletes at higher risk of developing eating disorders are those who participate in sports that use weight classifica- tion, such as rowing, judo, tae kwan do, weight lifting, and wrestling. Sports that emphasize body leanness, such as distance running, track, swimming, and cross-country skiing, are also associated with higher incidence of disordered eating.
