Assessment of Child and Adolescent Overweight and Obesity
-- Krebs et al. 120 (4): S193 -- Pediatrics
Here's a 36-page review, incl 336 citations. It purports to review assessment methods, and indeed it includes skinfolds and WC. But it avoids mentioning waist-to-height so far as I can tell.
I think that's strange for such a comprehensive review article.
