Objectives: This study was carried out with 31, 519(16,653 boys, 14,857 girls) of elementary school students to investigate the prevalence of obesity at a district in Gwangju City. It can be applied to develope an educational program of the obesity control as basic data in this local area
Methods: The data collected from May, 2004 to July, 2004 were analyzed by SAS PC+ 8.0 program. Children were selected depending on criteria from obesity index(%) by using physical index(height, body weight), and then subjects were classified into one of three groups according to the degree of obesity; mild(20∼29.9%), moderate(30∼49.9%), and severe(?50%) obesity.
Results: It showed that male elementary school students were higher and heavier than female elementary school students(p<.001) in every grade except the 4th grade(height) and the 6th grade( body weight). The obesity rates of male students(11.6%) showed higher(p< .001) than those of female students(8.8%). Specially the 4th grade elementary school boys were higher than any other groups in obesity(13.7%). As a whole, the prevalence of obestiy showed mild(5.9%), moderate(3.8%), and severe(0.6%). Male students showed higher rate of obesity than those of female students. The obesity of male students showed higher rate than that of female students except 2-3rd grade elementary school students(p< .001). The obesity of 4∼6th grade elementary school students showed higher rate than those of 1∼3rd grade students(p< .001).
Conclusions: The obesity rates of male students are higher than that of female students, and the obesity rates of 4∼6th grade students are higher than those of 1-3rd grade students in the elementary school. Additionally, these results suggest that the program may be needed to prevent obesity of children.
