title: [Effects of transtheoretical model intervention on improving self-esteem of obese children].
abstract: OBJECTIVE
  To explore the effects of transtheoretical model (TTM) intervention on improving self-esteem status of obese children.
  
  
  METHODS
  A quasi-experimental research was conducted using a repeated-measure, pretest-posttest control group design in one randomly-selected boarding school of Changsha, Hunan Province in China. Seventy-three obesity students (54 males, 19 females) among grade three to six were included. All participants received first assessment, including: demographic data, stage of change questionnaire, and the Self-Esteem Scale (SES). According to the baseline data, different intervention measures based on TTM were given to different students to promote them to begin exercise and improve their self-esteem status. Follow-up assessments were collected respectively at 1- and 6- month after intervention. Intervention effects on proportion of obese children and self-esteem status as well as BMI were explored. All analyses were conducted using SPSS 17.0.
  
  
  RESULTS
  After intervention, the proportion of obese children in precontemplation and maintenance stages was significantly different (P < 0.001). BMI and SES scores didn't change significantly. SES score was significantly different in five stages among three intervention points (P < 0.001).
  
  
  CONCLUSIONS
  Obesity children who are in the later stages have higher self-esteem scores than those in former stages. Intervention based on TTM can help obese children move through the stages of change.
