Abstract
To investigate the decrease of BMD by age and the risk factor of osteoporosis in Korean men. We describe the study of a five-years retrospective observational study with male patients. Eighty Korean men who visited hospital for health screening were assessed for this study from 2002 to 2006. We evaluated the BMD of the femoral neck and L-spine, and the preferences and habits in the life. The data were collected for 5 years, and we analysed the five-years change of BMD and the relations between BMD and other factors. Subjects were divided into 3 group by 1st assessment of femoral neck BMD, and were compared with each other. The age of subjects was $43.15{\pm}4.82$ and BMD of femoral neck was $-0.61{\pm}0.97$ and BMD of L-spine was $-0.67{\pm}1.10$ in the first year assessment. The femoral neck BMD of 4th and 5th assessment was decreased significantly compared to that of 1st assessment. The L-spine BMD of 2nd assessment was decreased significantly compared to the 1st assessment. There was no significant correlation between the changes of BMD and preferences or habits-drinking, smoking, eating habit, exercise. The femoral neck BMD of 5th assessment was decreased significantly compared to that of 1st assessment in the high femoral neck BMD group. And there was no significant change of femoral BMD and L-spine BMD in other groups. Low BMD group in the 1st assessment showed lowest BMD in the 5th assessment and high BMD group in the 1st assessment showed highest BMD in the 5th assessment. We can guess that the young men who has low BMD could have high risk of osteoporosis when he became older. And the femoral BMD should be considered important in anticipating the changes of BMD in middle aged men.
성인 남성들이 2002년부터 2006년 까지 건강검진을 받기위해 대학병원을 내원한 성인 남성 80명을 개인별 골밀도를 5년간 관찰하여 분석하였다. 연구 대상자 성인 남성 80명의 평균연령은 $43.15{\pm}4.82$세였다. 대퇴경부의 골밀도는 1차 측정에서 -0.61에 비하여 4차 및 5차 측정에서 유의하게 감소하였으며, 척추 골밀도는 1차 측정 -0.67에서 2차 측정에서 유의한 감소를 나타냈지만 3~5차 측정에서 유의한 차이를 보이지 않았다. 생활습관에 따른 음주, 흡연, 운동, 식습관에 따른 군 간의 대퇴경부 및 척추 골밀도 변화 값의 차이는 보이지 않았다. 1차 측정에서의 대퇴경부 골밀도를 기준으로 골밀도 상($0{\leqq}BMD$), 중($-1.0{\leqq}BMD<0$), 하(BMD < -1.0) 집단에서 1차 측정과 5차 측정 골밀도의 차이를 비교하였을 때, 상 집단에서 대퇴경부 골밀도가 1차 $0.67{\pm}0.76$에서 $0.42{\pm}0.93$로 유의하게 감소하였다. 다른 집단에서는 전후 비교에서 유의한 차이를 보이지 않았다. 대상자들의 나이에 관계없이 젊어서부터 골밀도가 낮은 사람들은 대퇴경부 및 척추의 골밀도가 낮아 있었으며, 골밀도가 높은 사람들은 1차 측정 때부터 5차 측정 때까지 높았다. 대퇴경의 골밀도는 1차 측정에 비해 5차에서 유의한 감소를 나타내어 척추보다는 대퇴경부의 골밀도에 주의하도록 한다.
