Abstract

This study is to analyze femoral necks and lumbar spine bone mineral density in Korean men aged 60 or older 2,736 people, as well as to research in its relation to anthropometry, life style, diet, fracture history, family history of osteoporosis and medical history using data from Korea National Health and Nutrition Examination Survey (KNHANES)(the 2nd(2008) and 3rd(2009) year at the 1st survey, and the 1st(2010) year at the 5th survey). To express the strength of the associations, percent differences were calculated from multiple linear regression models using the formula ${\beta}{\times}$(unit/mesnBMD). Unit for continuous variables were chosen to approximate 1 standard deviation(SD). Prevalence of osteoporosis for 60-69, 70-79 and >80 old men were 6.7%, 15.8% and 31.4% respectively. The proportion of osteoporosis calculated for each age group in the femoral neck group was: 60-69 years old, 2.6%, 70-79years old, 8.2%, >80years old, 24.8%. For the lumbar spine group, the values were: 60-69 years old, 5.5%, 70-79years old, 11.3%, >80years old, 15.4%. In men aged 60 or older, lean mass greatly influenced bone density in the femoral neck and lumbar spine. Thus, to increase the lean mass would be an effective way to prevent osteoporosis in elderly men.

본 연구는 국민건강영양조사 제 4기 2차년도(2008), 3차년도(2009), 제 5기 1차 년도(2010)에 참여한 60세 이상 남성노인 2,763명을 대상으로 대퇴경부 골밀도와 요추골밀도의 골밀도 수준을 파악하고, 신체계측, 생활습관, 식이섭취, 골절 과거력, 골다공증 가족력, 병력 등의 제 요인들과 골밀도의 관련성을 알아보고자 시도하였다. 각 변수의 단위별 BMD의 변화를 표현하기 위해 비율차이 계산식 ${\beta}{\times}$(단위/BMD의평균)를 이용한 다중선형회귀분석을 실시하였다. 모든 연속변수의 단위는 1SD를 사용하였다. 연구결과, 남성노인에서 골다공증 유병률은 60대는 6.7%, 70대는 15.8%, 80대이상은 31.4%이었고, 부위별 골다공증 유병률을 보면, 대퇴 경부부위 유병률은 60대는 2.6%, 70대는 8.2%, 80대이상은 24.8%, 요추부위 유병률은 60대는 5.5%, 70대는 11.3%, 80대이상은 15.4%이었다. 또한 대퇴경부 및 요추 골밀도에 조사된 각 독립변수 중 남성노인의 골밀도에 가장 큰 영향을 미치는 것은 제지방량으로 확인되었다. 따라서 남성노인에서는 제지방량을 늘리는 것이 골다공증을 예방하는 효과적인 방안이 될 것이다.
