LO 12.2 Describe the concepts of normal eating, disordered eating, and eating disorders. Compare and contrast anorexia nervosa, bulimia nervosa and binge eating disorder LO 12.3 State the prevalence of disordered eating and eating disorders in male and female athletes and explain the distinctions between athletes with eating disorders and those who are training intensely but do not have a disordered eating pattern. 3 3 Icebreaker: Disordered eating and eating disorders are deviations from normal eating habits and practices. To identify potential deviations, an individual must have a working definition for “normal eating.” What is your definition of “normal eating”? How has the current culture influenced this definition? 4 4 ©2019 Cengage Learning. All Rights Reserved.

It is being able to choose food you like and eat it and truly get enough of it – not just stop eating because you think you should. Normal eating is being able to use some moderate constraint in your food selection to get the right food, but not so restrictive that you miss out on pleasurable foods. Normal eating takes up some of your time and attention, but it keeps its place as only one important area of your life. Normal eating is flexible” Satter, 1987. 7 7 Normal eating in athletes Athlete’s diets often require careful plan ØEnsure adequate intake of macronutrients ØMinimize excessive caloric intake that may result in weight gain Diets may become more rigid at particular times ie competition season Normal eating amongst athletes is characterized by discipline, not obsession and inflexibility. 8 8 ©2019 Cengage Learning.

Eating disorders represent a substantial deviation from normal eating. There are different types of eating disorders that someone can be diagnosed with, according to the DSM-5 (classification and assessment tool for mental disorders). 9 9 Anorexia Nervosa Caloric restriction that results in a significantly low body weight for age. Intense fear of gaining weight Extremely distorted body image Behaviors to prevent weight gain even at a significantly low weight Restricting type Binge-eating/purging type 10 10 ©2019 Cengage Learning.

Adverse impacts on quality-of-life and health. Ie acute injuries, over-training. Often found in conjunction with eating disorders and disordered eating. Mechanism to control weight.

Include yo-yo dieting, restrictive eating patterns, removing whole food groups, fasting and then feasting patterns, rigid eating patterns, compulsive or dependent exercise. These behaviours are connected to attempts to lose weight or change body shape. 15 15 The Eating Continuum -Moderate restraint -Mild-moderate psychological -Significant psychological -Eating when hungry; pathology pathology stopping when full -Eating and hunger not aligned -Social isolation -Flexible eating pattern -Restrained and rigid eating -Body image distortion -No psychological -Food is restricted and perceived -Self-esteem associated with pathology negatively weight -Eating and weight normal -Compensatory behaviours -Extreme control or lack of emphasis in life -Weight and food control overemphasized -Rigid and inflexible eating - Diet extremely overemphasized compared to other areas of life 16 16 ©2019 Cengage Learning.

In athletes, this prevalence is much higher: modest estimate of 14-16% of athletes will experience an eating disorder in their lifetime. Estimates of disordered eating amongst athletes range from 6-45% in females and as high as 19% in males 17 17 Reference: Butterfly Foundation 18 18 ©2019 Cengage Learning. All Rights Reserved.

Trauma/Complex PTSD Cultural influences – “thin ideal” Major life events, changes or loss. Athletics/sports with thin bodies and weight requirements. 19 19 Engaging in dieting (food restriction to intentionally lose weight) is the single biggest predictor for the onset of an eating disorder. 20 20 ©2019 Cengage Learning.

Electrolyte imbalances and dehydration – impaired cardiac function, low blood pressure Gastrointestinal problems – bloating, constipation, diarrhoea, impaired intestinal function Dental problems if purging Impaired mood, cognitive and psychological functioning due to lack of nutrition à impaired decision making and emotional regulation. 21 21 Disordered Eating and Eating Disorders in Athletes 22 22 ©2019 Cengage Learning.

Difficulties in determining the presence of an eating disorder in athlete vs non- athlete populations due to disciplined eating and high-volume exercise required by athletes 23 23 Question: What sports do you think would have the highest prevalence of eating disorders? 24 24 ©2019 Cengage Learning.

Sports requiring a certified weight before competition do not have a higher prevalence of disordered eating. 27 27 Changes to eating and exercise behaviors are often gradual. Do you think you would be able to recognize early signs of an eating disorder in yourself or an athlete you are working with? Why or why not? 28 28 ©2019 Cengage Learning. All Rights Reserved.

Distress when unable to adhere to exercise plan. General social isolation, withdrawal or depression. 32 32 ©2019 Cengage Learning. All Rights Reserved.

This line may be crossed intentionally or unintentionally. 33 33 Signs and symptoms of EDs in athletes: Repeated injuries ie stress fractures or muscle injuries (may have continued to exercise despite initial pain or indicates low energy availability). Slow recovery from illness or injury, frequent illnesses. Gastrointestinal problems – constipation, diarrhoea. Rapid/unexplained weight gain or loss Iron deficiency anaemia Irregular or absence menstruation Sudden changes in food rules or patterns of eating. Bathroom visits after meals Avoiding eating with others and general social isolation, weary baggy and layered clothing. Relentless, excessive exercise. 34 34 ©2019 Cengage Learning.

What was the motivation for these changes? What influenced Allie’s diet restriction and onset of the eating disorder? 36 36 ©2019 Cengage Learning. All Rights Reserved.

Community treatment involves a GP, psychologist and dietitian (all suitably trained in eating disorder treatment) to address medical, nutritional and psychological pathologies. 37 37 ©2019 Cengage Learning.
