Here's a Newsweek article titled "Generation Diva: How our obsession with beauty is changing our kids."

An excerpt:

"these days, body dissatisfaction begins in grammar school. According to a 2004 study by the Dove Real Beauty campaign, 42 percent of first- to third-grade girls want to be thinner, while 81 percent of 10-year-olds are afraid of getting fat. "When you have tweens putting on firming cream"—as was revealed by 1 percent of girls in an NPD study—"it's clear they're looking for imaginary flaws," says Harvard psychologist Nancy Etcoff."
