Comparison of Body-Image Dissatisfaction Among Chinese Children and Adolescents at Different Pubertal Development Stages.

Background: Body-image dissatisfaction among children and adolescent has become increasingly serious, and may be the result of staged differences in the puberty-development process. The aim of this study was to compare differences in body-image dissatisfaction among children and adolescents at different pubertal stages. Methods: A total of 574 students aged 8-15 years were recruited from two nine-year schools via stratified cluster sampling, their secondary sex characteristics and external genital development examined, and body-image cognition surveyed using the teenage body-image annoyance questionnaire. This questionnaire covers body-shape, gender, sexual organ, and appearance dissatisfaction. Lower scores indicate a more negative body image. Results: Total, gender, and appearance-dissatisfaction scores in girls were significantly lower than in boys (P<0.05); however, sexual organ-dissatisfaction scores in girls were significantly higher than in boys (P<0.05). Girls' gender-dissatisfaction scores before breast development Tanner II were higher than those after menarche (P<0.05); however, girls' sexual organ-dissatisfaction scores before breast development Tanner II were significantly higher than those after menarche (P<0.05). Conclusion: The girls were more dissatisfied with their gender and appearance than the boys, and the boys were more dissatisfied with their sexual organs than the girls. The girls were more dissatisfied with their sexual organs before breast development Tanner II and more dissatisfied with their gender after menarche.
