I'd agree with Lou here. Those figures seem...off. I'd be interested to see the references for those. It's more than likely 1 in 100 preteens are on steroids if you include corticosteroids (in fact, 1 in 100 seems a bit low if you include corticosteroids).
As with any epidemiological study, the main issues have to do with defining your exposure, and defining your denominator population. Ambiguity with either of these can result in an incorrect estimate of prevalence or incidence.
