ABSTRACT
The purpose of this study was to investigate the relationship between body image discrepancy (BID) and weight status as measured by BMI percentiles (BMI%) among adolescents. A cross-sectional survey was conducted among 265 adolescents at an urban clinic (females 116 blacks and 63 whites; males 62 blacks and 24 whites). BID was the difference between ideal and current body images selected from a 13-figure rating scale, and BMI% were calculated from measured weight and height. Regression analyses were conducted separately for girls and boys. Over half of the female and one-third of male adolescents wanted a thinner body. BID was positively related to BMI% with a one-unit increase in BID associated with a 4.84-unit increase in BMI% among females and a 3.88-unit increase in BMI% in males. Both female and male adolescents reported BID beginning at a BMI% corresponding to a normal weight. At zero BID, white females had a BMI% of 62.6, statistically different from black females (BMI% 69.7). At zero BID, white males had a mean BMI% of 69 and black males at a BMI% of 75.8, not statistically different. While black and white differences exist in BID, black female adolescents like their white counterparts are reporting BID at a weight range that is within the "normal". Our study portends the increase in BID with the increasing prevalence of obesity and highlights the need for interventions to help adolescents develop a healthy and realistic body image and healthy ways to manage their weight.
