The Influence of Weight and Height Status on Psychological Problems of Elementary Schoolchildren through Child Behavior Checklist Analysis

PURPOSE This study aimed to evaluate weight and height status and their relationship with psychological problems among elementary schoolchildren. MATERIALS AND METHODS A total of 405 schoolchildren (211 boys and 194 girls, aged: 10-13 years), living in Seoul, Korea, participated in this study. The participants were divided into 3 groups according to their weight and height standard deviation score. Psychological assessments were performed using the Korean-Child Behavior Checklist (CBCL). RESULTS In this study, 34.4% of boys and 32.1% of girls showed dissatisfaction with their weight, whereas 26.2% of boys and 30.2% of girls showed dissatisfaction with their height. The obese group showed higher weight dissatisfaction than the normal or underweight groups (p < 0.001). The short stature group showed higher dissatisfaction in their height than the normal group (p = 0.01). There was no significant difference in total CBCL problems score according to weight or height status. The underweight and obese groups had higher score for social problems than normal weight group (p < 0.05 respectively). There were no significant differences in each CBCL problem score by height status. As a whole, the prevalence rate of a CBCL total problems score in the clinical range was 3 percent (12/405). These children showed no difference in terms of weight or height, compared with normal students. Among the factors related, only school performance was negatively correlated with the total problems score (p < 0.01). CONCLUSION Approximately one-third of elementary schoolchildren were dissatisfied with their height or weight. Although their total CBCL psychological problem scores were closely related with school performance, they did not show any significant relation with height or weight status. Contrary to the general view, our study suggests that psychological problems of elementary schoolchildren may be related more with their school performance than their body physique.
