Abstract

Objective To explore the relationship between body composition and bone mineral density (BMD) of female workers in a university of Tai'an. Methods This study randomly selected 90 female employees in a university of Tai'an. The body composition was monitored by body composition analyzer (inbody770), and the lumbar bone mineral density was monitored by dual energy X-ray absorptiometry (BMD model). The data were analyzed by SPSS 22.0 statistical software. Results With the increasing of body mass index (BMI), BMD of female lumbar spines 1-4 (L1-4) increased gradually. Spearman correlation analysis showed that BMI, skeletal muscle mass, upper limb muscle mass, trunk muscle mass, lower limb muscle mass, and whole-body phase angle were positively correlated with L1-4BMD. Age was negatively correlated with L1-4BMD. Linear regression analysis showed that age was a negative factor of L1-4BMD, and skeletal muscle mass was a protective factor of abnormal bone mass, especially lower limb muscle mass. Conclusions Lower limb muscle mass is a protective factor of female BMD. Strengthening physical exercise to improve lower limb muscle mass is conducive to the prevention of female osteoporosis.

Highlights

The aging population in China has been dramatically growing, which becomes a heavy burden for the government at all levels
The waist hip ratio and body fat percentage of the study group were higher than the normal level, and the body composition was
Taking lumbar spines 1-4 (L1-4) bone mineral density (BMD) as dependent variable and age, and upper limb muscle, trunk muscle, lower limb muscle, and whole-body phase angle as independent variables, linear regression analysis shows that age is a negative influencing factor of BMD, and lower limb muscle is a protective factor of BMD

Summary

Objective

To explore the relationship between body composition and bone mineral density (BMD) of female workers in a university of Tai’an. The body composition was monitored by body composition analyzer (inbody770), and the lumbar bone mineral density was monitored by dual energy X-ray absorptiometry (BMD model). With the increasing of body mass index (BMI), BMD of female lumbar spines 1-4 (L1-4) increased gradually. Spearman correlation analysis showed that BMI, skeletal muscle mass, upper limb muscle mass, trunk muscle mass, lower limb muscle mass, and whole-body phase angle were positively correlated with L1-4BMD. Linear regression analysis showed that age was a negative factor of L1-4BMD, and skeletal muscle mass was a protective factor of abnormal bone mass, especially lower limb muscle mass. Lower limb muscle mass is a protective factor of female BMD. Strengthening physical exercise to improve lower limb muscle mass is conducive to the prevention of female osteoporosis
