Describe the difference between feeding and eating

Feeding implies a relationship aspect - being given food by another - whereas eating is more autonomous


What percentage of parents with children below age 5 would say their child has a feeding difficulty?



Describe some factors involved in the progression from feeding to eating

Being able to select appropriate foods, being able to handle food (swallow, chew, use cutlery), sensory integration, managing social aspects of food, regulating food intake, effective interpretation of emotions (recognising when not feeling hungry means feeling upset), moving from dependence t self-care


Describe how the progression from feeding to eating relates to obesity

One theory of obesity states that parents who are overly controlling of their child's food intake lead to a child unable to recognise their own satiety cues, leading to issues with food regulation when they progress to controlling their own intake


Why is food often used by children to signal unhappiness to parents?

Mealtimes can be one of the few times when the whole family sits down and interacts


What is the difference between an eating disorder and disordered eating?

An eating disorder is a phenotype of behaviours, whereas disordered eating is a single behaviour


What is rumination disorder?

Where an individual regurgitates and re-swallows food - this is widely seen as a self-soothing behaviour


Which 2 population groups typically develop rumination disorder?

Those with disabilities and those who have experienced extreme trauma


In which 3 population groups is disordered eating more common?

Those with intellectual disabilities, those with severe food allergies, and type 1 diabetics - all groups which encourage the obsessive checking of food


What percentage of individuals with disordered eating have a comorbid medical condition?



What are eating disorders?

Mental health disorders n which people experience severe disturbances in their eating or behaviour intended to control weight, which significantly impairs physical health or psychosocial functioning


How are eating disorders distinguished from feeding disorders?

They are caused by negative thoughts about weight and shape


Give some examples of behaviours intended to control weight

Restricted eating, self-induced vomiting, excessive exercise, use of laxatives or diuretics, appetite suppressing medications (including caffeine and smoking)


How can eating disorders affect physical health?

They can impair growth and development in childhood and cause amenorrhoea, osteoporosis, and affects on the brain


Name the 7 eating disorders in DSM-V

Anorexia nervosa, bulimina nervosa, binge-eating disorder, atypical anorexia nervosa, atypical bulimia nervosa, purging disorder, night-eating syndrome


Define atypical anorexia nervosa

Exhibiting anorexia nervosa-type behaviour and losing a lot of weight very quickly but still falling within the normal weight range; typically affects individuals who were severely overweight


Define atypical bulimia nervosa

Exhibiting bulimia nervosa-type behaviour but not bingeing and purging often enough to meet criteria


State the 3 main diagnostic criteria for anorexia nervosa in DSM-V

1) Persistent restriction of energy intake leading to significantly low bodyweight in the context of what is minimally expected for age, sex, developmental trajectory, and physical health
2) Intense fear of gaining weight or persistent behaviour that interferes with weight gain, despite being low weight
3) Disturbance in the way one's body weight or shape is experienced or lack of recognition of the seriousness of current low body weight


Define binge eating

Eating in a discrete period of time (e.g. 2 hours) an amount of food that is definitely larger than most people would eat during a similar period of time and similar circumstances, and a sense of lack of control over eating during the episode


State the 5 main diagnostic criteria for bulimia nervosa in DSM-V

1) Recurrent episodes of binge eating
2) Recurrent inappropriate compensatory behaviour to prevent weight gain
3) Both binge eating and compensatory behaviours occur at least once a week for 3 months
4) Self-evaluation is unduly influenced by body shape and weight
5) Does not meet criteria for anorexia nervosa


State the 5 main diagnostic criteria for binge-eating disorder in DSM-V

1) Recurrent episodes of binge eating
2) Binge-eating associated with eating more rapidly than normal, eating until feeling uncomfortably full, eating when not hungry, eating alone due to embarrassment, or feelings of guilt or shame afterwards
3) Marked distress over binge eating
4) Binge eating occurs once a week for 3 months
5) Does not meet criteria for anorexia or bulimia nervosa


Is obesity an eating disorder?



Define avoidant-restrictive food intake disorder (ARFID)

An eating or feeding disturbance as manifested by persistent failure to meet appropriate nutritional or energy needs and associated with at least 1 of: significant weight loss or growth failure, significant nutritional deficiency, dependence on enteral feeding or supplements, or interference with psychosocial functioning


How is ARFID different to anorexia nervosa?

There is no evidence of disturbance in the way one's body weight or shape is experienced


State the 3 main subtypes of avoidant-restrictive food intake disorder (ARFID) (Bryant-Waugh et al, 2010)

Restricted type, sensory type, and phobic type


Describe the restricted subtype of ARFID

Not eating enough or showing little interest in feeding but with no restriction in food variety or texture. Also known as infantile anorexia


Describe the phobic type of ARFID

Refusing food due to past aversive experience, e.g. choking or anaphylaxis. Also known as post-traumatic feeding disorder


Describe the sensory type of ARFID and the main population group it affects

Accepting only a limited diet due to sensory fears, common in autism spectrum disorder


State the incidence of anorexia nervosa in adolescents (Smink et al, 2016)

26.7 per 100,000


State the incidence of anorexia nervosa in adolescent girls

50 per 100,000
