This study examines relationships among weight status, weight perceptions, and dieting behaviors in South Korean adolescents. As perceptions of an ideal body for teens in Korea have changed over time, it is important for school nurses to understand these relationships to help students achieve health. A cross-sectional survey of 3,191 8th and 2,252 11th-grade students from 21 middle and high schools across Korea completed a self-administered questionnaire. The prevalence of overweight among adolescents was 17.5% in males and 6.0% in females. Overall, 65.9% of students perceived their weight status accurately. Females overestimated their weight status 2.3 times more often than males. Male students underestimated their weight status 2.7 times more frequently than females. Approximately one third of participants misperceived their weight status, with variations existing between males and females. Study results suggest the need to develop male- and female-specific interventions to promote healthy body images and body weight.

The purpose of this study was to estimate the prevalence of overweight and examine relationships between weight status of children with intellectual disabilities (IDs), mothers' perceived weight status of children, and socioeconomic status (SES). A cross-sectional study of 206 mothers of children with IDs in six special schools in Seoul, South Korea, was conducted. Data were collected through school health record abstraction and parent survey during December 2004. Relationships between measures were assessed using chi-square (chi(2)) with Fisher's exact test, analysis of variance (ANOVA), and logistic regression modeling while stratifying by mothers who overestimated versus underestimated their children's weight status. Almost half (46.6%) of the children were overweight, and 72.8% of mothers accurately perceived their children's weight status. Overweight among children with IDs in South Korea appears to be a more prevalent problem than expected. This study suggests the need for school-based weight management interventions for children with special needs.

The high rates of overweight and obesity in children with intellectual disabilities highlight the need for interventions to help children achieve healthy weight. Before conducting weight management interventions, identifying risk factors that influence weight status in children with intellectual disabilities is an important step.
