Abstract

The purpose of this study was to analyze the relationship of body mass index (BMI), bone mineral density (BMD) and blood pressure (BP) in third and fourth decade college students. Total of 114 (67 male and 47 female) students who received health examination in April 2010 participated in this research. Bone status was measured by a peripheral dual energy X-ray absorptiometry method and T-score was calculated via WHO guideline. For body composition measurements, body fat, height and weight were measured and BMI was calculated. Among male students, 3.6% belong to the UW (under weight) group, 49.1% to the NW (normal weight) group, 18.2% to the OW (over weight) group and 29.1% belong to the obese group, while 2.1% of female students belong to the UW group, and 68.1% to the NW group, 14.9% to the OW group and 14.9% belong to the obese group. Differences of body weight among male and female students were statistically significant (p<0.001). Above overweight groups showed higher systolic and diastolic BP than normal group. Differences among two groups were statistically significant (systolic BP: p=0.041, diastolic BP: p=0.021). The mean BMI of normal BP group is 22.6+/-2.87, hypertension group is 24.1+/-2.95. Differences among two groups were statistically significant (p=0.045). The mean T-score of male students is -0.1+/-1.17, female is -0.6+/-0.88(total -0.5+/-0.91). Differences of T-score among male and female students were statistically significant (p=0.007). In conclusion, our results showed that many college students had the problems in the BMI, BMD and BP, and BP increased according to the increase of BMI. Therefore, nutritional education and weight control is required for normal blood pressure and bone health.
