Tuesday, May 08, 2007 1:38 am Email this article
Men and women overestimate how tall they are and underestimate how much they weigh according to a study from Italy.
Men overestimate height by 0.8 inches, women by 1.1 inches
Men overestimate their height by an average of 0.8 inches, while women overestimate their height by an average of 1.1 inches.
Men underestimate weight by 3.3 lbs, women by 4.2 lbs
Men underestimate their weight by an average of 3.3 pounds, while women underestimate their weight by an average of 4.2 pounds.
BMI underestimated by 1.1 units for men, 1.5 units for women
This overestimation of height and underestimation of weight underestimates BMI by an average of 1.1 units for men and 1.5 units for women.
Underestimation of Normal Weight
Prevelance of normal weight underestimated by 8%
Based on self-reported data, the prevelance of normal weight was overestimated by 12.2 percent in women and 4.3 percent in men.
(The study states these percentages as opposite for men and women, but I believe the paper has to be wrong because women overestimate their height and underestimate their weight to a greater extent than men which means that normal weight would be overestimated more in women than in men.)
Underestimation of Overweight
Prevelance of overweight underestimated by 8%
Based on self-reported data, the prevelance of overweight was underestimated by 8 percent in both men and women.
