Kids as young as 5 concerned about body image

I remember that girls in my classroom were embarrassed to show their results of physical strength check, when I was younger than 10. That's because it included weight data.
It means that they had already been able to concern about their shape through weight data, instead of how they actually look.
That's affected by their mothers, who measures their weight everyday?
We can't look down on their observation skills.
