Look at growth charts and how they can be useful in everyday practice• Use BMI look-up table – no calculator
required• Interpreting growth through puberty
Look at suitable themes to bring into discussion with families
Role play and cases – small group work
Aims
![Page 4: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/4.jpg)
Growth trends shine a light on health
Growth is best indicator of health
Charts demonstrate normal growth by age and stage of puberty - and in relation to parental height
Identify disorders of growth
Assess obesity
Isolated readings of weight height or BMI are inadequate – they must relate to the appropriate age/sex reference ranges which change throughout childhood

Breast-fed baby population trends
WHO produced charts that set breastfeeding as the norm and described optimal rather than average growth, that can be used worldwide.
Swap over from ‘breast-fed baby’ charts to UK-90 chart at age 4. (note the centile lines alter slightly at age 4)
There is a wider weight range in breast fed baby populations indicating that lower weight ranges can be normal

Body Mass Index (BMI) lookup
• Read weight and height centiles from the growth chart.
• Plot weight centile (left axis) against the height centile (bottom axis)
• Read off the corresponding BMI centile from the slanting lines
• Record centile on grid at top of chart
• Accurate to ¼ centile space
BMI =
91st centile

BMI Interpretation
A child whose weight is average for their height will have a BMI between the 25th and 75th centiles‘Growth’ continues into early 20s e.g. bone and muscle mass. Caution re restrictive dieting
For children yet to reach adult height:-
‘Growing into one’s weight’ means slowing down the rate of weight gain whilst further increase in height helps to normalise BMI
Children at full height will require weight loss in order for BMI to normalise
![Page 9: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/9.jpg)
BMI centile grid: plotting example
>91st centile suggests overweight>98th centile is very overweight (clinically obese)

Talking child obesity
It’s not only puppy fat...
‘Growing out’ of a weight problem requires altering ‘energy in/out’ balanceAdvising ‘eat less and exercise more’ should work - but it doesn’t… Avoid simplistic adviceObesity does not mean gluttony:- A small but prolonged energy imbalance can lead to obesity
![Page 13: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/13.jpg)

Promote positives - 'do's' rather than 'don'ts’
Focus on families not individuals - Encourage parents and carers to model a healthy lifestyle
Explore feelings to test water non-judgmentally
Test kids on what they already know - build on this
Relate lifestyle to a variety of health factors - dental care, fitness, bone and muscle strength, not just weight
![Page 15: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/15.jpg)
Teach concepts
Eat together as whole family - siblings and friends influence food preferences too
‘Do as I do rather than Do as I say’ - Children gradually learn to copy parent behaviours – diet and activity
Manage expectation of energy dense foods – ‘save for special times’
Reduce sugary drinks and increase consumption of water and milk
![Page 16: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/16.jpg)
Developing a ‘taste’ – varied diet
Children learn to accept new foods by repeated exposure and seeing others enjoy them
It may take many calm exposures to a new food for it to become ‘normal’ – food we eat and choose without giving much thought
Never force food – it creates strong dislikes and behaviour battles. Why do so many children dislike ‘greens!’
Use unusual settings, games and appealing presentation to generate positive associations
![Page 17: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/17.jpg)
Tuning in to appetite
Abandon ‘clear your plate’ concept – it teaches children to ignore appetite signals and risks eating whatever portion is served or simply to please others.
Parent guides – child decides
Involve children in choosing appropriate portion size – they know best how hungry they are and need practice choosing right amount
Think of ‘portions’ as handfuls – little hands, little portions
![Page 18: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/18.jpg)
Screen time
Avoiding being sedentary (reducing screen time) is strongly linked to preventing obesity – due to both the relation to activity and to exposure to advertising
4 hours a day screen time doubles the risk of overweight cf <1 hour
Having a TV in the bedroom is linked with overweight in young children
![Page 19: Slide set for Workshop 5 Child obesity challenges and opportunities Acknowledgments R Pryke](https://reader036.vdocuments.us/reader036/viewer/2022062715/56649da95503460f94a96822/html5/thumbnails/19.jpg)
Workshop 5 Cases – p 39
Divide into small groups 1. Plot the height and weight centile examples then
use the BMI Look up chart
2. Using ‘Bea’ as a case for role play, explain the concept ‘growing into one’s weight’ to Bea’s parent
Choose a caseTry the opening few sentences as role play to test out how phrases can come across. Discuss the other questions as a group
