I have compared and analyzed the changing pattern of their heights and weights based on their indices of physique and change of their growth pattern from the age of six to seventeen.
The conclusions obtained from this study were as follows:
1. The height of the urban students were taller than that of the rural area by 1.1 Cm?1.3 Cm, and the weight was heavier by 0.4 Kg?2.9 Kg.
2. From the age 6 to 9, the boys were taller than the girls by 0.5 Cm, but from the age 10 to 12 the height of boys and the girls was reversed. However, from the age 13, the boys became taller than girls and the difference reached about 11.3 Cm at age 17. But the revision of weight between boys and girls was showed from the age 10 to 13.
3. Rohrer indices of the rural were higher than that of urban students during the age 6 to 9, but after age 10, the students of urban area were more obese. And at the boys were more obese than the girls during age 6 to 10 but it was reversed after age 11.
4. Out of total 2,431 students, 105 students were obese at the age 6 in 12.8 to 38.1 percent of these students obesity was continued, and the rate of obesity was highest at age 12, as 38.1 %.
5. The tracking of obesity in urban students was increased to 20.1 %, until age 12, after then it was decreased gradually but, there are no significant tendency in rural students.
