Using pulmonary function and questionnaire data for 127 primary-school-age children (62 boys and 65 girls) in Kwangju city, we analyzed spirometric data (FVC. FEV_0.5, FEV_1, FEV_3, FEF_200-1200, FEF_25-75%) to determine the factors affecting the pulmonary function in 3 primary schools. The results were as follows; 1. Boys had higher value of spirometric data than do girls. 2. Obese children were tended to lower value of spirometric data than non-obese children in both sexes. 3. FEF_200-1200 were higher for taking exercise group than for not taking exercise group in boys. 4. FEV_0.5, FEF_200-1200, FEF_25-75% in boys and FVC and FEV_3 in girls were higher for group whose sleeping hours is less than 8 hours per day than for group whose sleeping hours is more than 8 hours per day. 5. Non-smoking status was associated with higher FVC, FEV_1, FEF_200-1200 in girls. 6. Spirometric data were correlated very strongly with height, weight, age in both sexes and there was a significant correlation between sleeping hours and spirometric data except FEF_25-75% and familial smoking amount and FVC in girls. We conclude that the management and education of environmental factors may be needed to improve pulmonary functions.

This prospective study was performed to find the associated factors of obesity in primary school children in Kwangju. We studied obesity incidence over 2 years among 4th grade primary school children, In 1994, base line study about 1,344 children of 4th grade was performed and in 2 years later, we reinvestigated health examination and questionnaire about several variables in 922. The 797 children included in the analysis had non-obese(normal and overweight) at baseline in 1994. This results were as follows; l. In 2 years later, 3.5% of normal and 15% of overweight children were to the obese. 2. The body mass index and obesity in one or both parents, sex, overweight at baseline, regular exercise and meat preference were statistically significant factors in simple analysis. 3. In multiple logistic regression analysis, the odds ratios associated with obesity were 0.41 (95% CI: 0.20-0.82) for female, 0.48(95% CI: 0.25-0.92) for doing regular exercise, 4,95(95% CI: 2.55-9.59) for overweight at baseline, and 3.22(95% CI: 1.11-9.34) for obesity in both parents. In conclusion, obesity incidence in primary school children was associated with physical characteristics, genetic factors and social factors like a life style. It is suggested that obesity management and appropriate regular exercise in family unit should be required to prevent obesity in children.
