| Objective To investigate the bone mineral density (BMD) in partial population of Langfang region, and to understand the relevant factors of the BMD variation and pathogenesis of osteoporosis in healthy people in Langfang. Methods BMD of the left distal 1/3 radius was measured in 1298 volunteers, including 382 men and 916 women, aging from 40 to 76 years old, with a mean of 53.28 ± 22.71 years old, using dual energy X-ray absorptiometry. All the data were divided in groups according to gender and age and analyzed using a SPSS 10.0 statistical software. BMD and the incidence of osteoporosis were analyzed according to 10-year-age division. Data between groups were compared using t test. The P value lower than 0.05 was considered statistically significant. Results BMI, milk, and soy played a protective role in BMD. Smoking and drinking led to a decrease of BMD. Conclusion BMI, daily habits, diet, and regular exercise can affect BMD. |
