This study aimed at examining the overall sleep features of elementary school children according to their grade, district, gender, mother"s education level and average income, and comparing the sleep features of normal children and obese children. The subjects of this study included a total of 662 children (boys: 309, girls: 353), and 346 of them were chosen from elementary schools randomly selected in Seoul and 316 from elementary schools in P City. The instrument used here to measure the sleep behavior of the elementary school students was a Korean version questionnaire of The Children"s Sleep Habits Questionnaire (CSHQ) developed by Owens, Spirito and McGuinn(2000). The results of the study were as follows. First, the elementary school children"s average bedtime, wake time and sleep latency turned out to be 22:22(p.m.), 7:24(a.m.) and 8.81(h) respectively. Second, the elementary school children showed no significant differences in bedtime, wake time or sleep latency according to gender.Third, the elementary school children showed significant differences in bedtime, wake time and sleep latency according to their grade. Fourth, the elementary school children displayed significant differences in bedtime, wake time and sleep latency according to the district where they lived. Fifth, as for the elementary school children"s sleep features according to the mother"s education level, children had later bedtime as their parents had higher education level. Sixth, with regard to the elementary school children" sleep behavior according to the mother"s average income, children had later bedtime as their parents" average income was higher, and had shorter sleep latency as their parents had lower average income. Seventh, obese children and normal children were compared. According to the results, the two groups showed no significant differences in bedtime, wake time and sleep latency. However, as for sleep related problems, the obese children accessed in the study displayed more sleep problematic behaviors of sleep disordered breathing, compared with their normal counterparts.
