The incidences of obesity in school children of urban area were compared with those of rural area, using Rohrer index as a parameter of obesity.
Body weight and height were measured in primary schools of both areas on May, 1982. The subjects studied were 2054 boys and 1887 girls in the ages from 6 to 12 years.
Incidences of obesity in urban and rural areas were 7.5% and 8.6% respectively (p<0.05).
For boys, average incidences of obesity in urban and rural school were 8.1%, and 7.5%, respectively. For girls, they were 7.2%, and 7.6%, respectively.
These results showed that there were no significant differences in incidences of obesity between the two districts and both sexes of school children.
We also found the eight cases of fatty liver in obese children.They were six boys and two girls, aged from 8 to 15.
In 7 of eight cases, obesity started from early childhood. During the first six months of life, they were fully fed cows milk formula. Of the cases, one developed hypertension, and two had hyperlipidemia.
With accurate exercise and optimal nutritional treatment, obesity, hepatic involvement and hypertension promptly improved. However, three cases had frequent recurrences.
Abdominal CTwas examined in six cases of the eight obese children with hepatic involvement. They showed that there were low CT numbers of liver in obese children with hepatic involvement.
The usefulness of abdominal CT in terms of evaluation of fatty liver in obese children was discussed.
