A cross-sectional study of changes in Norwegian adolescents' body image from 1992 to 2002.

The present study examines changes in adolescents' body image over a 10-year period. Both satisfaction with appearance in general, and satisfaction with different aspects of appearance (e.g., face, muscle tone, and weight) are considered. We analyzed data from two general population studies of 13-19-year-old Norwegians, "Young in Norway 1992" (N = 10,460, response rate = 97.0%) and "Young in Norway 2002" (N =1 1,371, response rate = 92.3%). These studies used identical sampling procedures, data collection procedures, and measures of body image. The analyses showed a polarization in adolescents' body image - concurrent with an increase in the proportion of adolescents with a very negative body image, there was an increase in the proportion of adolescents with a very positive body image. The greater proportion of adolescents with a very negative body image could partly be explained statistically by the increased body mass index (BMI) in the same period. Girls had a more problematic body image than boys, both in 1992 and in 2002. Whether the strength of this gender difference changed or not depended on the aspect of appearance considered.
