- Abstract
Objective To analyze the characteristics of body composition, muscle strength and cardiac function in elderly people with different bone densities. Methods This study was conducted from January 2019 to December 2021, A total of 500 subjects who underwent bone mineral density examination in the Health Management Center of our Hospital. The skeletal muscle index, body fat percentage, fat control muscle, muscle mass and muscle strength of right arm were measured and recorded. Cardiac function was recorded by ultrasound (EF, EDY, ESY, FS, HR, e/a). Results Among the 500 subjects, the number of people with abnormal bone mass was 77%, including 93 people with osteoporosis (18. 6%), 292 people with decreased bone mass (58. 4%) and 115 people with normal bone mass (23 %). In the male group, 21 (8. 4 %) were osteoporosis, 153 (61. 2 %) were bone loss, and 76 (30. 4 %) were normal bone mass. In the female group, 72(28. 8 %) were osteoporosis, 139(55. 6 %) were bone mass loss, and 39 (15. 6 %) were normal bone mass. The body fat percentage of female (37. 20 ± 4. 13) was higher than that of male (28. 15 ± 5. 38). the skeletal muscle index of females (8. 20 ±0. 58) was lower than that of males (9. 23 ± 0. 55) (P < 0. 05). Among the 500 subjects, the ratio of muscle control was 278 (55. 6 %), and the ratio of fat control was 500 (100 %). BMI, T value, Z value, skeletal muscle index, muscle control, right arm muscle mass and grip strength were compared among the three groups, and the differences were statistically significant (P < 0. 05). There were no significant differences in age, body fat percentage and fat control (P>0. 05). There were significant differences in BMI, T value, Z value, skeletal muscle index, muscle control, right arm muscle mass, right hand grip strength and left hand grip strength between the male group (P<0. 05). There were significant differences in T value, Z value, skeletal muscle index, muscle control, right arm muscle mass, right hand grip strength and left hand grip strength between the female group (P<0. 05). Pearson correlation analysis showed that T value was positively correlated with skeletal muscle index, BMI, right arm muscle mass and right hand grip strength. Compared with BMI, T value had a higher correlation with skeletal muscle index. It was negatively correlated with muscle control (muscle gain) (r = -0. 326, P = 0. 000). There was no correlation between T value and body fat percentage. In the three groups, EDY (F = 0. 042, P = 0. 958), ESY (F = 0. 008, P = 0. 992), EF (F =0. 060, P=0. 942), FS (F=0. 057, P=0. 945), HR(F =0. 032, P=0. 969) had no significant difference (P>0. 05). E/A (F= 3. 768, P = 0. 034) was significantly different (P<0. 05). Conclusion The rate of abnormal bone mass is higher in the elderly population. As bone mineral density decreases in the elderly, skeletal muscle index and muscle strength also decrease. Patients with osteoporosis may have decreased diastolic function. Using a body composition analyzer to analyze changes in the body composition of osteoporosis patients, we can learn about their muscle and fat content. The result provide a basis for further prevention and treatment of osteoporosis and optimization of body composition in the elderly.
