A Comparative Study on Body Composition and Lifestyles between Collegiate Students and Army Soldiers

&nbsp;&nbsp;From March-25, 2000 to April-2, 2000, we investigated anthropometry, body composition, and general lifestyle of 157 collegiate students in Kyung-Gi province and 106 soldiers of the Korean Army Soldiers in Kang-Won province. The results were as follows:<BR>&nbsp;&nbsp;1. There was no significant difference of the height between the students and the soldiers. The Weight of the students was 64.9±7.8㎏ compared to 69.3±7.1㎏ of the weight of the Army soldiers. The percent body fat was 17.0±4.l% and 14.8±3.2% for the students and the sold- iers, respectively.<BR>&nbsp;&nbsp;2. The trend of height is that the most highest population is the under fat groups, with the students 173.8±5.9㎝ and the soldiers 173.6±6.0㎝. The population with obese groups had the lowest height.<BR>&nbsp;&nbsp;3. TBW of the soldiers was 40.9±4.2ℓ, which is about 3.7ℓ more than TBW of the students. And the soldiers had more protein and mineral of body, about 1.4㎏ and 0.14㎏, respectively.<BR>&nbsp;&nbsp;4. In students, the obese group had the most TBW, 38.0±2.8ℓ. In sold- iers, the under fat soldiers, however, had the most TBW, 41.2±4.2ℓ.<BR>&nbsp;&nbsp;5. The percents of people with the iregular lifestyle were 79% and 17%, the students and soldiers, respectively, and the percent of people drinking three times per week were 29% and 3%, the students and soldiers, respectively.<BR>&nbsp;&nbsp;6. 51% in the students and 75% in the soldiers were smokers, and 64% in the students and 85% in the soldiers considered them healthy.<BR>&nbsp;&nbsp;7. 65% in the students and 7% in the soldiers have taken an irregular meal and 50% and 15% often had instant food.<BR>&nbsp;&nbsp;8. 25% in the students and 100% in the soldiers take an regular exercise, and frequency is 3 times per week and 5 times per week, students and soldiers respectively.<BR>&nbsp;&nbsp;9. In collegiate students, Pearson coefficient correlation between height and weight was proportional with r=0.320, between height and LBM with r=0.565, and also weight and WHR with r=0.490, weight and LBM with r=0.900, weight and percent body fat with r=0.559, WHR and LBM with r=0.311, percent body fat and WHR with r=0.515, smoking amount and lifestyle with r=0.277, smoking amount and frequency of drinking with r=0.370, but height and percent body fat had inverse proportion with r=-0.342.<BR>&nbsp;&nbsp;10. In Amy soldiers, Pearson coefficient correlation between height and weight was proportional with r=0.675, and also between height and LBM with r=0.744, weight and WHR with r=0.298, weight and LBM with r= 0.932, percent body fat and WHR with r=0.284. But Pearson coefficient correlation between percent body fat and smoking amount had inverse proportion with r=-0.240.
