Anthropomorphic characteristics of centerfold models were analyzed to determine if there has been a trend towards slimmer models over the last 50 years.Height and weight, breast, waist, and hip measurements of 559 Playboy centerfold models, obtained from the magazine's website, were analyzed.Regression analyses indicated a gradual and subtle change towards slimness. A latent class analysis yielded five basic types of figures and results indicated that the prevalence of the type of figures being depicted changed over time, with a slightly thinner figure being more common. However, really thin figures were rare until the 2000s and the probability of a model having a body mass index (BMI) < 17 was greater in the 1950s than in the 2000s.These findings suggest that there has been a trend towards slimness, but that the changes have been gradual. © 2005 by Wiley Periodicals, Inc.
