Abstract:
Objective:To analyze the relationship between body fat distribution and bone mineral content (BMC) in adolescents and gender differences among Chinese adolescents, and to provide a scientific basis for the prevention and treatment of bone metabolic diseases.
Methods:A total of 1 575 adolescents aged 12-18 years old were selected from Yinchuan by cluster random sampling. Body composition and bone mineral content were measured by bioelectrical impedance analysis(BIA). Multiple linear regression analysis was used to explore the relationship between body fat distribution and BMC after adjusting for confounding factors.
Results:Except for LTFR, the levels of FM, AFM, TFM, TrTFR and TrLFR in boys were lower than those in girls( t =-13.52， -15.18 ，-12.47，-12.25，-7.96， P <0.05); After adjusting for age, sex and weight, FM, AFM, TFM, TrTFR and TrLFR were all negatively correlated with BMC level( P <0.05). For each increase of 1 standard deviation in TFM, BMC level decreased by 0.53 standard deviation(95% CI=-0.57--0.49, P<0.01]. LTFR had a linear negative correlation with BMC level in boys( B=0.07, P <0.01), no similar correlation was found in girls( B=0.01, P =0.74). There was a linear negative correlation between TrLFR and BMC level in girls( B=-0.06, P =0.03), but the correlation was of no significance in boys( B=-0.01, P =0.55).
Conclusion:Sex difference in body fat distribution in Chinese adolescents is observed. Body fat distribution is closely related to bone minerals content in adolescents.
