Most conversations about body image focus on teenagers. It's easy to assume that three or four is far too young for any of this to matter. The evidence says otherwise.
Anti-fat bias shows up by age three
Researchers study this with very young children using simple picture tasks that need no reading and very little talking. Children are shown drawings of figures in different sizes and asked which one is happy, which one has friends, and so on. Studies like this show that children as young as three reliably favour thinner figures and give more negative traits to figures at higher weights.
In children aged three to five, anti-fat bias has been shown to increase with age. Researchers at La Trobe University in Australia found the same pattern: five-year-olds showed a stronger size bias than three-year-olds. As Dr Siân McLean put it, young children "reflect our society: these are the biases adults hold too."
This matters for two reasons. Children who hold more weight bias also tend to have higher levels of depression, anxiety and low self-esteem. And anti-fat bias doesn't only shape how children feel about themselves - it shapes how they treat each other.
Early years practitioners are already seeing it
In a survey of 361 childcare professionals by PACEY (the Professional Association for Childcare and Early Years):
nearly a third had heard a child calling themselves fat
a quarter had seen signs that children aged three to five were already worried about how they look
around one in five had seen children refuse food because they said it would make them fat
71% said children were becoming anxious about body image at a younger age
Body dissatisfaction starts before school, too
It isn't only bias towards other people. A systematic review of 16 studies found that children under six do experience body dissatisfaction. The proportion ranged from around 20% to 70%, depending on how it was measured. The review also found that parents appear to be an important influence on how preschool children feel about their own bodies.
A recent review of UK research with children aged four to 12 found that their views about body size and weight are present from an early age. Those views are bound up with what children are told about health and physical ability.
Why this means starting early
The pattern across this research is clear. Body shame is hugely impacted by the environment and culture around children. Older children show stronger bias than younger ones, and children's attitudes track the attitudes of the adults around them. They pick it up from the comments adults make about their own appearance, about food and weight, and from the books, screens and conversations around them - and even from the wider school environment, such as how healthy eating or PE is taught or how school food standards are communicated.
That's exactly why body image is a cultural issue that needs cultural solutions, and why prevention can't wait until secondary school. The early years are when these attitudes first take shape. They're also when the adults in a child's life have the most influence over which messages stick.
Where we come in
We’re proud to work across age groups, with workshops and resources from EYFS right up to KS4 - and a training offer for university staff too. Our community programme includes participants from ages 0-70+ and we know that starting this work early (and involving families as much as possible too) is the true path to prevention.
Earlier this month, our facilitator Claire spent a day with Nursery, Reception and KS1 classes at a school in Cambridge. Afterwards, one of the teachers wrote to tell us that "the children responded so positively to the hands-on activities throughout the sessions". Other staff commented on how well Claire connected with the children and how smoothly the workshops ran. They told us it was brilliant to see the children so engaged - proof that a strengths-based approach to body respect education can be joyful, curriculum-aligned and absolutely appropriate for all age groups, if delivered with expertise, skill, care and a proper framework. This is where we come in!
If you'd like to bring body respect into your early years setting or school we’d love to hear from you. Send us an email at hello@bodyhappyorg.com - or check out our standalone sessions and whole school programmes.
We talked about this exact subject - and so much more - when our Executive Director Molly Forbes spoke on this episode of the Pop That Mumma podcast. Listen to the episode “Raising Body Confident Kids in a Body Obsessed World” where ever you get your podcasts.
