Purpose: In this study, nutrient intake during the adolescent period is a critical time for the development of the vision. Therefore we analyzed the relationship between the obesity index and the refractive power. Methods: We used the Korean National Health and Nutrition Examination Survey 2010 document. The obesity index is classified as Broca index (less than 80.0% is low weight, 80 to 89.9% is underweight, 90.0 to 109.9% is normal, overweight is from 110.0 to 119.9%, 120.0% or more is obesity) and body mass index (BMI)(less than 18.5 is underweight, 18.6~22.9 is normal, 23.0 to 24.9 is overweight, and obesity is higher than 25.0). We analyzed correlation with the body mass index and refractive error in adolescent. Results: As shown in the statistics, according to Broca index and body mass index (BMI), the refractive power and the obesity index showed a statistically significant correlation in the ages 15 to 18. Under weight subjects are ingested 43.84% dietary fiber, vitamin C 56.55%, 35.20% iron, 31.84% of, and 38.03% potassium less than the average food intake by the standard group. Conclusions: Moderate weight with a broad variety of taking nutrition and good eating habits seems to have an effect to the good growth and the good vision.

The purpose of this study is to investigate the differences in body fat distribution between obese boys and girls in high school and the relationship between the precent of body fat and the Broca Index. The survey of data was conducted from November 3rd to the 11th in 1997. The data were analyzed by the use of a mean, standard deviation and a Pearson's correlation coefficient. Measurements of the percentage of body fat and lean body mass were made by a Bioelectrical Impedence while height, weigh and the Broca index were measured by a fatness measuring system. First, measurements of height, weight and the Broca index were made by a fatness measuring system on 1,125 1st year students and 1,076 2nd year students. The result of measurements, 216 obese boys and 100 obese girls appeared to have above 10% of the Broca index. The result of this study can be summarized as follows: 1) Obese boys and girls were grouped by the level of the Broca index as follows: boys, 110-less than 120 60.0%, 120-less than 130 20.8%, 130-less than 140 11.1%, above 140 7.4%. ; girls, 110-less than 120 44.4%, 120-less than 130 32.0%, 130-less than 140 13.0%, above 140 11.0%. 2) Obese boys and girls were grouped by level of the percentage of body fat by Bioelectrical Impedence as follows: boys, less than 20% 5%, 20%-less than 25% 34.7%, above 25% 33.8% ; girls. less than 25% 15.0%, 25%-less than 30% 43.0%, above 30% 42.0%. 3) In obese boys the Broca index score appeared to be positively related to body weight(r = .741, p<.001), the percent of body fat(r=.604, p<.001), lean body mass(r=.375, p<.001), body fluid(r=.445, p<.001l). On the other hand the percent of body fat was not a significant correlation of lean body mass (r= -.074), body fluid(r= -.073). 4) In obese girls, the Broca index score appeared to be positively related to body weight(r= .693, p<.001), the percent of body fat(r=.645, p<.001), lean body mass(r=.531, p<.001), body fluid(r=.532, p<.01), and the percent of body weight score appeared to be positively related to lean body mass(r=.206, p<.01), body fluid(r=.207, p<.01).
