골다공증은 골량을 반영하는 골밀도의 감소로 골격이 약화되어 골절의 위험을 증가시키는 질환이다. 발생률은 중년 이후 성인에 서 높아지고 고연령으로 갈수록 급격히 증가한다. 골다공증은 무 증상으로 골밀도 검사를 하지 않은 경우에서는 인지하지 못할 수 있고, 골절 발생 후 알게되는 경우가 흔하고, 골절은 고령자에게 치 명적인 결과를 초래하기도 한다.
Purpose: This study aimed to examine the factors related to the bone mineral density (BMD) in male and female adults aged 50 years or older. The factors included were socio-demographics, body mass index (BMI), blood pressure, blood lipids, and health habits. Methods: As a secondary data analysis, this study used raw data from the 5th Korean National Health and Nutrition Examination Survey, and selected 2,295 adults aged over 50 years who participated in the survey and had BMD values. The T-score of the femoral neck was evaluated for BMD. Data were analyzed using descriptive statistics, ANOVA and multiple regression. Results: The factors influencing the BMD in men were age (β=-.029, p<.001), BMI (β=.100, p<.001), triglyceride (β=-.001, p=.001), and calcium (β=.001, p=.003), and the suggested regression equation explained 25.6% of the variance in BMD (F=16.32, p<.001). The factors related to BMD in women were age (β=-.060, p<.001), BMI (β=.091, p<.001), total cholesterol (β=-.002, p=.028), HDL cholesterol (β=.009, p=.001), and calcium (β=.001, p=.004), and the suggested regression equation explained 47.0% of the variance in BMD (F=61.72, p<.001). Conclusion: Based on the findings of this study, the modifiable factors, such as BMI, blood cholesterol, and calcium, should be targeted to improve the BMD in both men and women.
