Abstract

Objectives: The purpose of this study was to (1) determine the prevalence of weight misperception among overweight and obese men with total body fat levels ≥ 25%, and (2) examine associations of weight misperception with anthropometric and body composition measures.

Methods: Data came from 4,200 overweight or obese men from the 1999 to 2006 National Health and Nutrition Examination Survey. Weight misperception was operationalized as having a dual-energy X-ray absorptiometry-derived total body fat percentage ≥25% and classifying oneself as either "underweight" or "about right weight." Logistic regression was used to determine physical characteristics associated with weight misperception.

Results: Weight misperception was highest among Mexican American (35.9%) followed by Black (30.8%) and White men (22.9%). Physical characteristics (OR, 95% CI) associated with weight misperception were decreased arm fat (0.95, 0.91-0.98), being overweight (9.02, 5.34-15.24), and having a waist circumference ≤ 94 cm (2.31, 1.72-3.09).

Conclusions: Findings suggest that future research should include a measure of adiposity in the operationalization of weight misperception among male populations.
