For new high school students (431 persons), an evaluation of the relationship between body shape
(BMI: calculated by height and weight) and HDL-C, LDL-C, and ALT are summarized below.
Firstly, the percentages of skinny students (BMI＜18.5) and obese students (BMI≧25) based on BMI
were examined. The percentages of skinny students are 6.9% (15/218 persons) for males and 12.7% (27/213
persons) for females, and of obese students are 11.5% (25/218 persons) for male and 4.7% (10/213 persons)
for females.
Secondly, the relationship between BMI and biochemical markers were examined by using Pearson's
correlation coefficient. For male students, the relationship between BMI and HDL-C is significantly
negative at r＝－0.26, p＜0.05. Conversely, there is a positive correlation between BMI and LDL-C (r＝0.27,
p＜0.05), as well as ALT (r＝0.57, p＜0.01). In addition, there is a significant positive correlation between
ALT and LDL-C (r＝0.27, p＜0.05). For female students, there is no significant correlation between BMI
and HDL-C, LDL-C or ALT.
These results suggest that from around the second growth spurt, the body shape might change to
visceral fatty obesity in males and to subcutaneous fatty obesity in females
