Relationship between Bone Mineral Density and Pulmonary Function in Adult Females

ABSTRACT

BACKGROUND: Reduced pulmonary function is a common outcome in pulmonary patients with reduced bone mineral density. But, there are few studies on the relationship in adult females who do not have pulmonary diseases. Thus, this study was to assess the correlation between bone mineral density and pulmonary function in healthy women. METHODS: A total of 193 subjects was selected among adult females who visited a health promotion center. BMD was measured by Dual energy X-ray absorptiometry and T-score of lumbar spine (L1-L4) was used. Pulmonary function was measured by spirometer and questionnaire survey was used to obtain information from the subjects. RESULTS: Mean T-score of L-spine was -0.284, FEV1 (pred %) was 98.82% and BMI was 23.50 kg/m2. The results showed positive correlation (0.128) between BMD and FEV1 by multiple regression analysis (P<0.05). CONCLUSION: As FEV1 of subjects increased, BMD increased in adult women who did not have pulmonary diseases.
