Alternative methods of nutritional status assessment in adolescents.
The main objective of this cross-sectional study was to determine the validity of the silhouette rating scale and reported values of height and weight in assessing weight status in a group of adolescents. 245 adolescents, students of the Belgrade elementary school, aged 11-14 (12.33 +/- 0.50), were involved. Weight status was assessed by anthropometry, self-reported height and weight and by figure rating scale. From the results obtained significant differences emerged as a function of weight status. The majority of normal weight adolescents were accurate in reporting their body size. The percentage of under-reporters was significantly higher in the overweight/obese group than in the normal weight group (chi2 = 9.741, p = 0.003). The correlation between BMI, both measured and self-reported, and perceived body size was positive and highly significant (p < 0.001). Self-reported weight and height appears acceptable for estimating weight status in normal weight adolescents, but not in those who are overweight or obese. This study also demonstrated that adolescents can estimate with some accuracy their body size using figure ratings scales.
