Abstract

Background/ObjectiveWeight misperception is common among adolescents with obesity, but it is not known whether weight perception is related to future weight gain. The objective of the study was to examine the prospective association between accurate weight perception versus weight misperception and weight change among youth who are overweight or obese.Subjects/MethodsUsing a subsample of The National Longitudinal Study of Adolescent to Adult Health Wave II cohort, we used linear regression modeling (adjusted for age, baseline BMI, parental education, household percent federal poverty level, depression, race, and ethnicity) to examine the prospective association between weight misperception (i.e., perceiving oneself to be under or normal weight) among 2738 overweight and obese youth and subsequent BMI change from Wave II (1996) to Wave IV (2008-2009). Mean age at baseline (Wave II) was 15.9 (0.1).ResultsFifty-seven percent of males and 80% of females accurately perceived themselves as overweight. In fully adjusted models, weight misperception was associated with less BMI gain among youth who were overweight and obese. Specifically, youth who perceived themselves to be at a healthy weight had lower BMI gains (males: beta=-1.43, 95% CI=[-2.26, -0.60], P=0.001; females: beta=-1.35, 95% CI=[-2.59, -0.11], P=0.035) from Wave II to IV relative to those who accurately perceived themselves as overweight or obese.ConclusionsContrary to commonly held assumptions, weight misperception among a non-clinical sample of youth who were overweight or obese predicted lower future weight gain. Efficacy of efforts to correct weight misperception should be rigorously examined to assess for both intended and unintended consequences.
