According to the Journal of Pediatrics, 54% of one-month old babies using disposable diapers had rashes. THAT IS MORE THAN HALF! Of those 16% were severe rashes. Cathy Allison, in her article, "Disposable Diapers: Potential Health Hazards?," cited a study done by Procter & Gamble (manufacturers of Pampers® and Luvs®) that, rather humorously - I think, concluded that the incidence of diaper rash INCREASES from 7.1% to 61% with increased use of THEIR diapers! Bet Procter & Gamble wishes it never prompted that study, eh? Mark Fearer in "Diaper Debate - Not Over Yet," stated that "Several independent medical studies document an astounding increase [in diaper rash]: from 7% in 1955 to 78% in 1991. Critics of disposables say this parallels the increase in usage for disposables."
