Underassessment of weight and weight management in patients with diabetes: one more reason in support of weight management advice.

Abstract

The purpose of this study was to determine whether underassessment of weight affects weight management behaviors of overweight and obese individuals with diabetes and to determine whether weight management advice from health care professionals modifies the effect of underassessment of weight. Data (n=979) from the 2006 and 2008 National Health and Nutrition Examination Survey were analyzed. Multivariate logistic regression was used to identify factors associated with underassessment of weight, weight management behaviors, and receipt of weight management advice from health care professionals. Underassessment of weight was common (26%). Men, overweight persons, Blacks and Hispanics were more likely to underassess their weight. Those who underassessed their weight were 53% less likely to report weight management behaviors, odds ratio 0.47 (95% CI=0.31-0.73). Weight management advice increased weight management behaviors among individuals who underassessed their weight, 3.49 (95% CI=1.70-7.18). Underassessment of weight can negatively affect weight management behaviors of overweight and obese individuals with diabetes. Weight management advice from health care professionals is important, and can modify the effect of underassessment of weight on weight management behaviors in this high risk group.
