This study was conducted to monitor bone density changes of South Korean college students from year to year. The subjects were divided into groups according to gender (male and female) and investigation period (group 1: 2003-2005, group 2: 2006-2008, and group 3: 2009-2011).The height, body weight, BMI (body mass index) were 174.4/173.8/176.3 cm, 66.7/67.4/69.2 kg, and 21.9/22.3/22.2 kg/m² for the male groups, and 160.8/161.7/161.2 cm, 54.7/54.1/53.2 kg, and 21.2/20.7/20.5 kg/m² for the female groups, respectively. The BQI was 109.9/97.7/87.5 for the male groups, and 89.6/82.1/79.9 for the female groups, respectively. The osteopenia and osteoporosis percentages were 15.8/26.3/39.2% and 0.0/0.9/4.3% for the male groups, and 38.8/56.2/59.8% and 0.5/3.8/6.6% for the female groups, respectively. For males, heights of the different groups were significantly different. Among females, BMI values were significantly different between the groups. BQI and T-scores were significantly and negatively correlated with height in the male groups. In the female groups, BQI, T -scores, %young adult, Z-scores, and %age-matched had a significantly positive correlation with weight and BMI. Based on these findings, it was concluded that the bone density of college students is decreasing on a yearly bases. The results of this study suggest systematic and practical programs for college students are needed to improve bone density and maintain bone health. [ABSTRACT FROM AUTHOR] |
