| Objective To explore the methods to improve bone mineral density (BMD) by investigating the relationship between life style and BMD in the elderly people. Methods Basic conditions and life style of 100 elderly people were investigated and graded. Basic conditions consisted of gender, marital status, degree of education, and medications. And life style included smoking, diet habit, sunbath, exercise, and the medication of calcium and vitamin D. BMD of the femur and the lumbar vertebrae was tested. The relationship between life style and BMD in elderly people was analyzed. Results Only 18% elderly people had normal BMD. The normal rate of BMD of the elderly people, who had lifestyles with a higher score, was higher than that of those people who had lifestyles with a lower score. And the difference was significant (P<0.05). Conclusion To cultivate better life style gradually is an important method to improve BMD in the elderly people. |
