Association between measured BMI and self-perceived body size in Mexican adults.

Aim: The study examined the association between perceived body size (through self-selection of Stunkard's body shape silhouettes) and measured body mass index (BMI) in Mexican Mestiso adult men and women, and determined the BMI values that corresponded to each silhouette.

Subjects: A sample of 1092 men and 1247 women, apparently healthy, aged 20-69, was studied.

Methods: Participants were asked to identify the silhouette that most accurately represented his/her body size.
