Abstract:
Objective To investigate the correlation between body composition and bone mass in postmenopausal women and its application value.
Methods Clinical data of 80 postmenopausal women accepting body composition analysis in the Medical Examination Center of the People’s Hospital of Jieyang from June 2015 to May 2016 were retrospectively studied. The informed consents of all women were obtained and the local ethical committee approval had been received. According to the bone mass value, these women were divided into the normal bone mass group and the low bone mass group. Seventeen women were included into the normal bone mass group with an average age of (60±6) years old, and the other 63 women were included into the low bone mass group with an average age of (61±5) years old. The indexes of age, height, body weight, fat content, muscle quality, presumptive bone mass, bone proportion, estrogen, body fat and muscle rate were compared between the two groups. The data of the two groups were compared using t test, and the correlation analyses between bone proportion and body fat and muscle rate were conducted using Pearson correlation analysis.
Results The body weight, fat content and body fat rate of the women in the low bone mass group were (62±7) kg, (22.8±3.3) kg and (37±5)% respectively, which were significantly higher than (57±7) kg, (19.1±2.3) kg and (33±4)% of those women in the normal bone mass group (t=2.222, 4.228, 2.685, P<0.05); the presumptive bone mass, bone proportion, muscle rate and estrogen level of the women in the low bone mass group were (1.94±0.28) kg, (3.2±0.5)%, (60±5)% and (51±7) pg/ml respectively, which were significantly lower than (2.26±0.27)kg, (3.9±0.3)%, (63±4)% and (69±8) pg/ml of those women in the normal bone mass group (t=4.212, 6.584, 2.092, 9.223, P<0.05). Bone proportion was negatively correlated with body fat rate (Y= –12.84X+0.84, r= –0.742, P<0.001), but positively correlated with muscle rate (Y=11.96X+0.16, r=0.696, P<0.001).
Conclusion Bone mass is related with the change of body fat and muscle in postmenopausal women, so analyzing body fat and muscle rate may contribute to evaluating and forecasting the risk of osteoporosis in postmenopausal women.
